TL;DR: We propose a framework StereoMap that measures large language models' perceptions of social groups using dimensions of Warmth and Competence

Abstract: Large Language Models (LLMs) have been observed to encode and perpetuate harmful associations present in the training data. We propose a theoretically grounded framework called StereoMap to gain insights into their perceptions of how demographic groups have been viewed by society. The framework is grounded in the Stereotype Content Model (SCM); a well-established theory from psychology. According to SCM, stereotypes are not all alike. Instead, the dimensions of Warmth and Competence serve as the factors that delineate the nature of stereotypes. Based on the SCM theory, StereoMap maps LLMs' perceptions of social groups (defined by socio-demographic features) using the dimensions of Warmth and Competence. Furthermore, the framework enables the investigation of keywords and verbalizations of reasoning of LLMs' judgments to uncover underlying factors influencing their perceptions.

Our results show that LLMs exhibit a diverse range of perceptions towards these groups, characterized by mixed evaluations along the dimensions of Warmth and Competence. Furthermore, analyzing the reasonings of LLMs, our findings indicate that LLMs demonstrate an awareness of social disparities, often stating statistical data and research findings to support their reasoning. This study contributes to the understanding of how LLMs perceive and represent social groups, shedding light on their potential biases and the perpetuation of harmful associations.

Abstract
research has demonstrated that LLMs exhibit as- sociations between Muslims and violence, as well as between specific gender pronouns (c.g. she) and stereotypical occupations (e.g. homemaker) (Abid et al., 2021; Bolukbasi et al.. 2016). To address these concerns, various measurement tech- niques and mitigation strategies have been devel- oped (Nadeem et al., 2021; Nangia et al., 2020; Schick al., 2021). For example, benchmark datasets have been proposed to capture stereotyp- ing in LLMs by presenting two contrastive pairs (e.g. (the poor, the rich). (Whites, Asians)) based on various sociodemographic and cultural dimen- sions (e.g. race, gender, ethnicity), allowing for a comparison of the likelihood of these associations in LLM outputs (Nadeem al., 2021; Nangia al., 2020).
Large Language Models (LLMs) have been observed to encode and perpetuate harmful associations present in the training data. We propose a theoretically grounded framework called #STEREOMAP to gain insights into their perceptions of how demographic groups have been viewed by society. The framework is grounded in the Stereotype Content Model (SCM); a well-established theory from psychology. According to SCM, stereotypes not all alike. Instead, the dimensions of Warmth and Competence serve as the factors delineate the nature stereotypes. Based the SCM theory, S STEREOMAP maps LLMs perceptions of social groups (defined by socio- demographic features) using the dimensions of Warmth and Competence. Furthermore, the framework enables the investigation of keywords and verbalizations of reasoning of LLMs' judgments to uncover underlying factors influencing their perceptions.
Despite the utility of benchmark datasets for captur- ing biased stereotyping LLMs, there have been valid critiques regarding construct validity (what the test is measuring) and the operationalization of the construct (how well the test is measuring it) (Blodgett et al., 2021). These benchmark datasets often rely crowd-soureed crowd-worker data itself without a strong theoretical foundation support the underlying assumptions. While such data can provide valuable insights, we argue that incorporating cstablished and validated thcories from psychology can enhance the measurement of stereotypes in LLMs by providing a theoretical framework to identify the dimensions that consti- tute stereotypes and based on that develop robust metrics and methods for measuring and interpreting stereotypes (Cao al., 2022; Fraser al., 2021). To work towards this goal, we propose frame- work that we call #STEREOMAP. which serves as a comprehensive testbed for measuring stereo- types LLMs. This framework grounded in the
Our results show that LLMs exhibit a diverse range of perceptions towards these groups characterized by mixed evaluations along the dimensions of Warmth and Competence. Furthermore, analyzing the reasonings of LLMs, findings indicate that L.MSs demonstrate an awareness of social disparities, often stating statistical data and research findings to support their reasoning. This study contributes to the understanding of how LLMs perceive and represent social groups, shedding light their potential biases and the perpetuation of harmful associations.

widely adopted Stereotype Content Model (SCM) put forth by Fiske al. (2002). To be specific, the SCM posits that individuals and groups are perceived based on two fundamental dimensions: WARMTH and COMPETENCE. In contrast to the notion of stereotypes being uniform hostility, the SCM plots stereotypes in a two-dimensional vec- tor space between warmth and competence that contribute stereotypes.
We propose a comprehensive framework "STERBOMP as testbed for understanding stereotypes encoded in LLMs. This frame- work provides a systematic approach to as- sess and analyze the perceptions of how social groups are viewed in society by LLMs based on a validated and widely adopted theory from psychology, namely the SCM ($3)
We conduct an in-depth analysis of the current saae-of-thheari LLMs using #STEREOMAY framework: this analysis includes a thorough examination of Warmth-Competenee dimen- sions and the reasoning verbalizations of the LLMs' perceptions. By investigating the asso- ciations between Warmth, Competence, Emo- tions, and Behavioral tendencies, we shed light on the extent to which LLMs align with the findings from psychology literature on stereotypes ($5)
The proposed framework aims to analyze the per- ceptions of how social groups are viewed in society by Language Models (LLMs) through the dimen- sions of Warmth and Competence, while also con- sidering the associated emotions and behavioral tendencies. By mapping LLMs' understanding of social groups onto these dimensions, we plore their connections to emotions such as pity, contempt, envy, and admiration, as well as behav- ioral tendencies such as active or passive facili- tation or harm. Additionally, we investigate the keywords and reasoning verbalizations of the judg- ments made by LLMs to gain insights into the un- derlying factors influencing their perceptions.
Building upon findings, we discuss the potential implications and applications of the framework for researchers and model design- ers. By understanding the stereotypes encoded LLMs, we can better assess and mitigate the potential negative impacts of these mod- els in various domains, leading to the more responsible and ethical use of LLMs.($6)
The findings of our study indicate that LLMs ex- hibit a diverse range of perceptions toward social groups, characterized by mixed evaluations along the dimensions of Warmth and Competence. These findings align with previous research in psychology. highlighting the existence of multifaceted stereo- types. However, some variations exist among the models studied.
Background
2.1 Stereotype Content Model
The Stereotype Content Model (SCM) introduced and validated by Fiske et al. (2002) is a well- established psychological theory that posits two fundamental dimensions along which individuals and groups are perceived: Warmth and Compe- tence. According to (Fiske et al., 2002), these di- mensions the two primary factors in human cognition that serve an adaptive mechanism in social interaction. When encountering unfamil- iar individuals, individuals engage in a cognitive assessment process to determine whether these in- dividuals are potential allies or adversaries. This assessment is related to the Warmth dimension, which encompasses qualities such as being warm, trustworthy, and friendly. Simultancously. individ- uals also evaluate the perceived capability of these individuals to upon their intentions, whether be to provide help or inflict harm. This evalu- ation is captured by the Competence dimensions, which encompass traits such as competence, skill-
Furthermore, our analysis of the reasoning behind LLMs' judgments relation to the economic sta- tus of social groups reveals a notable awareness of societal disparities. Some models even claim statis- tical data and research findings as their reasoning. This suggests that LLMs have some understand- ing of the complex social dynamics and disparities present within society.
By examining LLMs' perceptions, emotions, be- havioral tendencies, and reasoning verbalizations, our framework contributes to a deeper understand- ing of how language models comprehend and repre- sent social groups. These insights provide valuable insights for further research and development of LLMs, aiming improve their fairness, accuracy, and unbiased portrayal of diverse social groups

fulness, and assertiveness. To validate this hypoth- esis, Fiske et al. (2002) conducted human subject experiments involving participants who were pre- sented with questionnaires designed to assess their perceptions of stereotypes. Through these exper- iments, the SCM was empirically tested and val- idated providing insights into how Warmth and Competence dimensions influence the perception of individuals and groups in social contexts.
recent research has revealed the need for more comprehensive taxonomy. The study of additional other dimensions of stereotypes, such as Agency- Deliefs-Communine (ABC) (Koch et al., 2016) and Morality, Sociability, Ability, and Assertiveness (Abele et al., 2016) (both explained below), have demonstrated their distinct predictive power and relevance in social perception.
The ABC model (Koch et al., 2016), for instance, found that socioeconomic Status (referred to as Agency) and progressive-tradiionna Beliefs were the dimensions that explain the stereotype con- tent. To be specific, they employed a data-driven approach, collecting responses from participants and allowing the dimensions to emerge organically, rather than using predefined dimensions. Although the SCM acknowledges the role of Status as a struc- tural antecedent of Competence (that is, Status functions as a predictor for Competence), SCM didn't 't explicitly model Status as content dimen- sion. Additionally, Abele et al. (2016) have pro- posed subdividing Warmth into specific elements of Morality and Sociability, and Competence into Ability and Assertiveness.
According Fiske al. (2002), stereotypes are not characterized uniformly but rather exhibit a range of combinations along the dimensions of warmth and competence. Some social groups are perceived as both warm and competent, often re- ferred to as the in-groups (e.g. middle class), while others are perceived as both incompetent and hos- tile (e.g. homeless individuals). Other groups characterized by mix of warmth and competence by their scale, e.g., they might be seen high in warmth but low in competence (e.g. elderly peo- ple), or high in competence but low in warmth (e.g. wealthy individuals).
This theory has practical implications: subsequent studies have provided further support for the sta- bility of these dimensions across cultures (Fiske, 2018) and their predictive value in understanding emotions and behavioral tendencies (Cuddy et al., 2007). For example, Cuddy et al. (2007) demon- strated how the Warmth-Competene dimension is closely linked to specific emotional responses and behavioral inclinations: clusters characterized by high Warmth and low Competence are associated with feelings of pity and sympathy, while those characterized by low Warmth and high Compe- tence evoke emotions of envy and jealousy. Groups that score high on both dimensions elicit admi- ration and pride. Cuddy et al. (2007) found that groups perceived as admired (warm and competent) clicit both active and passive facilitation tendencies, while groups perceived as hated (cold and incompe- tent) elicit both active and passive harm tendencies. Envied groups (competent but cold) elicit passive facilitation but active harm, whereas pitied groups (warm but incompetent) elicit active facilitation but passive harm.
To incorporate these advancements in theory ad- vancement, Nicolas et al. (2022) introduced an open-ended response-based approach measure stereotypes. This methodology collects individu- als' spontaneous responses in the form of adjectives or nouns that describe social groups asked about. These responses are then mapped to a Stereotype Content Dictionary (Nicolas et al.. 2021), which assigns words to distinct dimensions, such as so- ciability, and morality. This framework allows for more nuanced understanding of the multidimen- sional nature of stereotypes and offers compre- hensive means of measuring them.

3.1 Warmth-Competen Analysis
We issued the Warmth- Carmth-Competence prompt for ev- ery social group listed in Appendix B. The social demographic group encompasses ethnic entities (e.g., Asians), gender delineations (e.g., Men), reli- gious affiliations (e.g.. Christians), and vocational groups (e.g., Scientists). We then extracted ratings for each group and dimension (Warmth and Compe- tence), and averaged the ratings, yielding Warmth and Competence scores for each group. Consistent with the approach used by Fiske et al. (2002), we conducted K-means clustering with the number of clusters set to 5. Paired r-tests were performed to assess the statistical significance of differences be- tween the Competence and Warmth scores for each cluster.

et al., 2002), and EXTENDED version, which incor- porates additional dimensions identified as relevant in recent research (Nicolas et al., 2022) (Table 7).
the EXTENDED version, we adopted prompt design process inspired by the CHAIN-OF: THOUGHTS (CoT) framework (Wei et al., 2022). The CoT suggests that structuring prompts in a step-by-step manner outlined below can improve performance in tasks involving common-sense rea- soning. In CoT-inspired prompt design, first prompt the LLMs provide keywords that describe the social group under consideration. We then request the LLMs to provide the reasons be- hind their chosen keywords, aiming to gain insights into their "thought" process. Finally, we ask the LLMs to rate each dimension individually, allow- ing for comprehensive assessment of the vari- ous dimensions within the context of the social target. While our questions the LLMs do not have right or wrong answers, we adopt the CoT- inspired prompt design to enhance the quality and depth of the LLMs' responses. Sensitivity checks prompts are presented in Appendix L..
To explore the relationship between Warmth and Competence and their influence on emotions and behavioral tendencies, we used the EXTENDED prompt design as described in Table 7- Emotion and Behavior. The ratings obtained from the model were subjected to group-level correlation analyses, using Spearman's 's p, to examine the associations between stereotypes and emotions as well behav- ioral tendencies. Furthermore, cluster-level anal- yses were conducted to analyze the relationships among Warmth, Competence, and these factors.
3.2 Keywords and Reasoning Analysis
To ensure the credibility of the ratings provided by the LLMs, it is erucial to delve into their responses and underlying reasoning beyond the numerical scores. accomplish this, we employed an open- ended query format that prompted the LLMs to pro- vide keywords describing the social target, accom-

panied by the reasons for those chosen keywords. To analyze the keywords, we utilized the Stereotype Content Dictionary (Nicolas et al., 2021), which of- fers a comprehensive linkage between words (e.g., confident) to specific dimensions (e.g., assertive- ness) and their corresponding directions (c.g., high). By mapping the keywords provided by the LLMs to dimensions and directions, we were able to exam- ine the variations across clusters in terms of these dimensions.
petence and Warmth scores within each cluster, paired r-tests were performed. The results of the 1-tests are presented in Table
Presence of mixed dimension clusters The re- sults show that all three models exhibited mixed- dimension clusters, (e.g. High Competence- Low Warmth), albeit with some variations. The BARD and GFT-3.5 models consistenlly result in a cluster with higher Competence than Warmth, comprising the groups Asians, Jews, and Rich people. This finding aligns with the previous research by Fiske et al. (2002), which also identified Asians and Rich people in this cluster. Although DAVINCI'S 's model did not yield a significant cluster, Asians and Jews were grouped together with higher Competence than Warmth. Also, all tested models produce clus- ters with higher Warmth than Competence, with the consistent inclusion of elderly people. This observation is consistent with (Fiske et al., 2002) findings that elderly people are perceived to have higher Warmth than Competence.
Furthermore, we conducted a reasoning analy- sis, with a particular focus on the aspect of status (e.g., How economically successful have group been?)?. Given the significance of status crucial predictor of competence in social groups, detailed exploration was conducted. For this analysis, we employed the SentenceTrans- former all-MiniLM-LG-v2 in conjunction with KEYBERT (Grootendorst, 2020) to extract key- words from the reasons provided. By comparing the extracted keywords across models and clusters, our aim was to identify the distinctive characteris- ties of the LLMs' reasoning verbalizations. The texts were pre-processed lowercase, stopwords were removed, and the group mentions were re- placed with the pronoun 'they', as the group men- tions exhibited correlations with frequency, which may subsequently impact the results.

Extreme clusters The clusters characterized by notably high Competence and Warmth on both di- mensions are commonly referred to as "in-groups" (Fiske et al., 2002). These in in-groups serve as so- cietal reference groups, as many groups perceive themselves as part of the broader societal norm.

wise, the BARD model yielded an in-group cluster comprising Christians, middle-classed people, stu- dents, blue-collar workers, and Muslims. However, for the DAVINCI model, the results did reveal matching clusters within these groups.

We report the group-level findings in Appendix G.
On the opposite end of the spectrum, we observed the presence of a cluster characterized by low competence and warmth, which was consistent across all three models. This cluster includes homeless people, aligning with the findings of Fiske's model (Fiske et al., 2002).
The emotion results (Figure 3) indicate that across all three tested models, the cluster labeled as 0 (low Competence and low Warmth), showed higher aver- age ratings for Pity compared to other clusters.

Additionally, Cluster 4, charac- terized by high Competence and high Warmth, had the highest mean rating for Admire among all other clusters. These findings align with the conclusions of Fiske et al. (2002), suggesting that the language models' perceptions of emotions and stereotypes resemble those of humans.
from government departments and research centers (e.g., median salary, according to the U.S. Cen- sus Bureau, from the Pew Research Center). On the other hand, DAVINCI and GPT-3.5 demonstrate similarities in their reasoning patterns, emphasizing factors such as public perception and media influ- ence (e.g., generally viewed, (from) media, public), This similarity can be attributed to the shared tac- tics applied in the models' development, with sub- tle differences in model size. The comprehensive list of keywords by clusters across models is pre- sented in Table 10, and sample reasoning examples can be found in Table 11. The results highlight the models' awareness of systematic inequality, perpet- uating disparities, and poverty prevalent in society. For instance, common keywords across all mod- els in Cluster 0 (Tab 10) include phrases such stigmatized (by) society, stigma, poverty, difficulty, while Cluster 1 is characterized by the keyword society discrimination.
In terms of behavioral ratings, Cluster 4 consis- tently exhibited the highest mean scores for active facilitation across all models, with Cluster 3 con- sistently ranking second. This pattern also held true for passive facilitation, such as association, For the DAVINCI, no specific differences were ob- served among the clusters, although Cluster dis- played higher mean ratings. In the case of GPT- 3.5, Cluster 2, characterized by higher competence than warmth, had the highest mean rating for active harm, For the BARD, similar to DAVINCI, no signif- icant differences were found among the other clus- ters, but Cluster 0 exhibited higher mean ratings for both active harm and passive harm, accompa- nied by larger variances. These findings align with Cuddy et al. (2007), in that admired (c.g., Cluster 4) groups elicited both facilitation tendencies and hated groups (e.g.. Cluster 0) elicited both harm tendencies.

In Figure 4, we present the top five dimensions and their corresponding direction across the clusters, focusing on the DAVINCI model. The results of other models are presented in Figure 8. Cluster 0 (low Competence and low Warmth), exhibits nega- tive directions for Morality, Status, and Health, as expected. Cluster (lower competence compared to the other clusters excluding Cluster 0) also dis- plays distinctive patterns. We further investigated this via group-level analysis, which allows for a more in-depth comparison between groups (Figure 7). The details of keyword coverage are presented in Appendix M.
Discussions
The practical implications of the SSTEREOMAP framework for practitioners and researchers involve identifying and mitigating harmful stereotypes. We argue that facilitating normative discussions and conducting comprehensive evaluations of down- stream tasks are essential. Leveraging STERE- ОMАР, researchers can gain a deep understand- ing of LLMs' perceptions of social groups and the underlying reasoning behind them. This under- standing can guide the identification of harmful stereotypes and inform strategies for their mitiga- tion. We list potential ways how practitioners and researchers can make informed decisions based on T SAEREOMAP.

Potential Approaches The identification of harm- ful stereotypes and their contextual manifestations is imperative, particularly in real-world scenarios. LMs applied in downstream tasks encompass ious sections, such factual answering (Petroni et al., 2019), common sense reasoning (Liu et al., 2022), text summarization (Liu and Lapata, 2019), and casual conversation (Zhang et al., 2020). One potential strategy involves leveraging the insights provided by the STEREOMAP framework and tai- loring the analysis to specific downstream tasks, thereby identifying potential points of failure. For instance, Dhamala et al. (2021) proposes set of prompts based on diverse sociodemographic fac- tors, enabling the measurement metrics such as sentiment, toxicity, and regard in relation to the model's outputs. In addition to employing random prompts with sociodemographic information, an- other avenue for investigation is the utilization of STEREOMAP to delve into the interconnections between dimensions of warmth and competence. This approach enables thorough and systematic analysis, thereby facilitating comprehensive ex- ploration of stereotypes.

cerning the detrimental impact of stereotypes and the implementation of effective strategies to miti- gate them essential. Previous research has identi- fied harmful stereotypes as associations that deviate from the expected probabilities derived from cen- sus data, such as the LMs' association between occupations and gender (Bolukbasi et al., 2016; Touileb et al., 2023; Kirk et al., 2021).
Our analysis of LMs shows that while LMs possess the ability to understand and conceptualize social groups, they also possess understanding of sys- tematic discrimination and disparities existing in society. We note that the encoding of stereotypes in LMs itself is not inherently problematic; rather, it is the potential consequences and biases that may arise from their use.
Conclusion
We present the #STEREOMAP framework, which offers theory-grounded and computational ap- proach to mapping the perceptions social groups by LLMs along the dimensions of Warmth and

Competence. Our findings reveal that LLMs dis- play wide range of perceptions toward these so- cial groups, exhibiting mixed evaluations along the dimensions of Warmth and Competence. The framework serves as a foundation for identifying and capturing potential biases and harmful stereo- types embedded within LLMs. By providing comprehensive understanding of LLMs' percep- tions, STEREOMA AP we contribute to the ongo- ing discourse on the responsible deployment and mitigation of biases in language models.

We focused on the explicit understanding of stereo- types by utilizing predefined sets of groups and mapping keywords to predetermined dimensions. This approach may overlook other implicitly held and nuanced stereotypes. Also, our analysis fo- cused on stereotypes prevalent in the US. Stereo- types can vary across cultures and regions, and our findings may not generalize to other contexts.

A Model Configuration
C
Related Work: Measuring Stereotypes in Language Models
The selection of BARD was motivated by its avail- ability the public and its interaction with broader audience, resulting in a potentially larger impact compared to other proprietary models. No- tably, BARD provides up to three versions of an- swers, and we collected any optional answers of- fered by the model.
The presence of stereotypes in language models has been extensively documented in numerous studies. These stereotypes encompass various aspects, such as gender associations with specific occupations and racial biases in hate speech detection (Boluk- basi et al., 2016; Sap et al., 2019; Abid et al., 2021; Kirk et al., 2021).
As for the GPT-3 models, text-davinci-003 and gpt- 3.5-turbo, they are presumed to correspond to the Chat-GPT model but with different stylistic char- acteristies: chat completion and text completion, respectively. For SANT--AVINCI-003, we main- tained the default values provided by the OpenAl API, and made a single adjustment by setting the temperature to a value of 0 5. to allow moderate level of randomness. Given that our model was de- signed for text completion, we divided the prompt into individual questions for querying purposes.
To evaluate and measure the presence of stereo- types, several benchmark datasets have been intro- duced (Nadeem et al., 2021; Nangia et al., 2020). These datasets employ metrics that assess the like- lihood of generating stereotypical responses, often presenting contrasting pairs for comparison. How- ever, these benchmark datasets have faced criticism regarding their construct validity, specifically in terms of how the contrasting pairs and metrics op- erationalize and reproduce stereotypes (Blodgett et al., 2021).
To address these limitations and advance the mea- surement of stereotypes in language models, re- cent research has proposed a method that adopts theory-grounded approach to measuring stereo- types (Cao al., 2022; Fraser et al., 2021). In a similar vein, propose comprehensive frame- work that integrates diverse theories grounded in the measurement stereotypes.

beit with some variations. In the case of DAVINCI, and GPT-3.5, clusters featuring Elderly people, Women, and Christians demonstrate higher Warmth than Competence. This result aligns with (Fiske et al., 2002). However, for BARD, the cluster in- volving Elderly people do not exhibit statisti- cally significant difference between Competence and Warmth. On the other hand, clusters with higher Competence than Warmth consistently in- clude Lawyers, the Rich, and CEOs consistently across all models.
During our analysis, we observed instances where the model refused to provide a response certain queries. The refusals were indicated by responses such as "I'm unable to help you with that, as I'm only a language model and don't have the necessary information or abilities.". S "I' sorry, cannot generate inappropriate or discriminatory content. It is not ethical or professional.".
We dub these responses as "refuse tonsse-tt-asweer and report the refuse-to-answer rates across models in had the highest rate, having Poor Blacks approximately 1, indicating that rarely answered questions concerning Poor Blacks. Conversely, DAVINCI had the lowest aver- age rate, with the highest social group, Young, at 0.05. This refuse-to-answee rate can indicate to what extent, and to whom, the models are sensitive answering questions regarding stereotypes.
Furthermore, all the models consistently show the presence of extreme cluster. This cluster com- prises in-groups such Nurses, Doctors, Jews, Professionals, Educated, and Ivy-leaguers. Con- versely, low- Warmth and low www-Competence clus- ter consistently involved the Homeless, Criminals, and Drug addicts consistently across all models.

Conversely, no signifi- cant patterns were found for pity across all models, while envy consistently exhibited a positive and sig- nificant correlation with passive facilitation. This implies that individuals who evoke feelings of envy are more likely to receive passive assistance from others.
H Other dimensions beyond Warmth, Competence
When examining the correlation between emotions and behavioral tendencies, we found positive as- sociation between admiration and both active and passive facilitation. This suggests that individuals who elicit admiration are more likely be per- ceived to receive supportive actions from others, regardless whether those actions are actively ini-

may not solely be attributed to cluster assignment but rather stem from inherent differences between the groups, such as the case of Democrats and Re- publicans. As anticipated, variations in political orientation are evident, with Democrats focusing more on morality and Republicans emphasizing agency.

Table 10 presents the clustcr-level keywords ex- tracted across the models. These findings align with the observations outlined in Table 3. The ex- tracted keywords shed light on the awareness of social discrimination and societal inequalities by LLMs, evidenced by the consistent keywords across models, such as "stigmatized." " "poverty diffi- culty," " "negative prejudices," and "negative percep- tions" (Cluster 0), as well as "barriers," " "economic individuals," "underrepreseented and "discrimina- tion" (Cluster 1). In contrast, keywords associated with Clusters 3 and 4 indicate notions of "greater access" and "greater opportunities."

Table 5: Warmth-Competene analysis EXTENDED prompts. We sampled the groups from each cluster based on DAVINCI. The (C. W) respectively corre- sponds to the Competence and Warmth averaged ratings each cluster. To assess statistical significance, we performed paired f-test compare the Competence and Warmth scores. A significance level of (p<.007) was used, with symbols '>" '<' indicating a significant difference between Competence and Warmth. If the p-value was not significant (p>=.001), we denoted as "E' to indicate no significant difference between Com- petence and Warmth.
These findings suggest that LLMs demonstrate understanding of the presence of social disparities and the challenges faced by marginalized groups. The consistent use of keywords related to stigmati- zation, poverty, discrimination, and limited oppor- tunities across different models implies an aware- ness of these societal issues.
I Group-level Keywords Analysis
Figure 7 illustrates examples of the group-level keyword analysis. The Venn diagram showcases the keywords associated with two distinct social groups, while the bar graph shows the dimension and their directions aggregated across the keywords (summed over by group). Specifically, we highlight cases where two groups exhibit contrasting char- acteristics: Nurses and Doctors (located in Cluster 4) and Women and Men (located in Cluster 3), as well as Democrats (in Cluster 3) and Republicans (in Cluster 2).
The results reveal that despite belonging to the same cluster, different adjectives are used to empha- size distinct traits within these groups. For instance, nurses exhibit stronger emphasis morality com- pared to ability, while women prioritize status as a prominent dimension, contrasting with men who prioritize agency. Furthermore, for groups located in separate clusters, significant differences in key- words are observed. However, these distinctions

Men
Achievement, Opportunity, and Wealth Achievement refers to the success that men have had in achieving economic success, such as eurning higher wages and having more job opportunities than women. Opportunity refers to the fact that men have had more access to resources such as education and capital that have enabled them to become more successful economically. Wealth refers the fact that men have been able accumulate more wealth than women, which has given them greater economic security and the ability to pass on their wcalth to future generations.

Men
Historically, men have held positions of power and dominance in various aspects of socicty, including the economy. This has contributed to the perception that men are more successful economically.
Despite the progress made in recent years, there is still significant wage gap between men and women in many industries. This disparity in carnings reinforces the notion that men more economically successful.
Society often places pressure men he the primary breadwinners in their families and achieve success in their carcers. This expectation may contrihute to the perception that men are more successful economically.

K Human Evaluation
L Prompt Sensitivity Analysis
To assess the given framework and model re- sponses, we additionally conducted human eval- uations. We sampled 5 responses per every so- cial demographic group across 3 models Davinci, Gpt-3.5, and Bard. The assessments are obtained through 3 individuals participating in the evaluation process. Criteria considered for human evaluation are:
In Section 3, we introduced subtle refinements to create the final prompts, including the Chain of Thoughts(CoT) style prompt. In Table 14, we present an ablation analysis on the variations of the prompts: prompts without CoT (-w/o CoT), prompts without Instructions (-w/o Instructions), and prompts without CoT and Instructions (-w/o Instructiio.. We ran an extra 5 rounds of each prompt style per every social demographic group considered. The metrics we adopted are the coefficient of Variation (CV), the variability relative to the mean conditioned on each social demographic group (represented the ratio of the standard deviation (6)) to the mean (μ), (H), indicators of score consistency, Self-BLEU (Zhu et al., 2018), and Entropy over n-gram distribution (Zhang et al., 2018), as indicators of the diversity in reasoning. We also calculated the Refuse to Answer ratio given each style of prompt.
Relevance (between Scores and Reasoning): The alignment between the scores assigned by the models and the reasoning they provided. This assessment discerns the congruence be- tween the generated ratings and the accompa- nying rationale. The score scale ranged be- tween 0 (not relevant) to 1 (relevant) Soundness (between Keywords and Reason- ing): This criterion scrutinized whether the keywords employed by the models were in harmony with the provided reasoning. The scale ranged between O (no sound) to 1 (sound)
The results show the marginal differences between prompt styles, with the mean score consistency ranging from 0.03 to 0.04. (We also calculated the consistency CV between the chosen prompt and the prompt w/o CoT, w/o Instruction, and w/o CoT+instructions, giving CV avg of 0.093, 0.094, and 0.093 respectively, which indicates high consistency across prompt types.) The reasoning diversity scores also showed marginal differences, with the Self-BLEU score ranging from 0.062 to 0.065. Along with the metries, manually had look at the model-generatee responses for each style and chose the prompt that had the lowest refuse-to-answer ratio given diverse reasoning scores in presenting our results.
Coherence: Given the iterative nature of our evaluation, we placed emphasis on coherence, investigating if the models consistently gen- erated coherent outputs across multiple in- stances. The scores ranged from 0 (not co- herent) to (coherent)
Table 12 shows the human evaluation results. The scores obtained in human evaluation were fairly high, around 0.8 to 0.9. Note that these evaluation criteria are to discern whether the scores or model responses are right or wrong, but rather to assess the coherence, and soundness of the mod- els' outputs which mainly focus on the framework evaluation.
M Keyword Analysis Details
In section 3.2 and 5.2 we presented keywords anal- ysis. Table 15 shows the coverage details of the processed keywords. The initial coverage (rowl, 1, Initial Coverage) was around 60%. To enhance it, we employed lemmatization on generated words, using the spacy en en_core_wt sarr__we_ssme lemmatizer. This led to increased coverage, as shown in row 2. For the remaining uncovered words, manual inspec- tion revealed instances where two-word phrases failed be lemmatized (e.g.. 'risk takers', 'risk taking' to 'risk taker'). We manually mapped those cases which ended up with the coverage noted row 3. While an option to increase coverage ex-

We acknowledge and understand the concerns you’ve raised, and we’re pleased to provide clarifications on our methodological choices. \n\nThe main objective of this research was to examine the large language models’ (LLMs) behavior. To this end, we adopted an experimental design that has been well grounded in theory and that has been well validated. Thus, the fundamental foundation and configuration of our prompts were, in essence, drawn from a prior study [1],[2]. These prompts represent the questions that were specifically designed to gauge stereotypes among human subjects, incorporating a meticulous construct validity approach. This informed our decision to adopt these questions as the cornerstone of our research. By utilizing these questions as our baseline, we sought to establish a meaningful parallel between the behavior (responses) of LLMs and human responses within a controlled context. \n\nBuilding on this chosen foundation, we introduced subtle refinements to create the final prompts, including the incorporation of a Chain of Thoughts (CoT) style prompt.  Below, we present an ablation analysis on the variations of the prompts: prompts without CoT (w/o CoT), prompts without Instructions (w/o Instructions), and prompts without CoT and Instructions (w/o CoT+Instructions). We ran an extra 5 rounds of each prompt style per every social demographic group considered. The metrics we adopted are the coefficient of Variation (CV), the variability relative to the mean conditioned on each social demographic group (represented as the ratio of the standard deviation (σ) to the mean (μ) ($\\frac{\\sigma}{\\mu}$) as indicators of score consistency, Self-BLEU [3], and Entropy over n-gram distribution [4], as indicators of the diversity in reasoning. We also calculated the Refuse to Answer ratio given each style of prompt.  \n\n|                                | Score Consistency       |                     | Reasoning Diversity |              |              | Refuse to Answer Ratio (%)  |   |   |   |\n|--------------------------------|-------------------------|---------------------|---------------------|--------------|--------------|-----------------------------|---|---|---|\n| Prompt Type                    | Competence CV Avg (max) | Warmth CV Avg (max) | Self-BLEU (↓)       | Entropy-2(↑) | Entropy-3(↑) |                             |   |   |   |\n| Prompt (paper)                 | .043 (.296)             | .032 (.250)         | 0.064               | 12.02        | 16.28        | 0.01                        |   |   |   |\n|         - w/o CoT              | .041 (.279)             | .048 (.263)         | 0.065               | 10.77        | 14.41        | 0.053                       |   |   |   |\n|         - w/o Instructions     | .042 (.165)             | .031 (.093)         | 0.062               | 10.83        | 14.49        | 0.057                       |   |   |   |\n|         - w/o CoT+Instructions | .040 (.279)             | .046 (.263)         | 0.065               | 10.85        | 14.51        | 0.055                       |   |   |   |\n\nThe results show the marginal differences between prompt styles, with the mean score consistency ranging from 0.03 to 0.04. (We also calculated the consistency CV between the chosen prompt and the prompt w/o CoT, w/o Instruction, and w/o CoT+instructions, giving CV avg of 0.093, 0.094, and 0.093 respectively, which indicates high consistency across prompt types.) The reasoning diversity scores also showed marginal differences, with the Self-BLEU score ranging from 0.062 to 0.065.  Along with the metrics, we manually had a look at the model-generated responses for each style and chose the prompt that had the lowest refuse-to-answer ratio given diverse reasoning scores in presenting our results.   \n\nTo assess the given framework and model responses, we additionally conducted human evaluations. We sampled 5 responses per every social demographic group across 3 models - Davinci, Gpt-3.5, and BARD. We obtained the assessments through 3 individuals participating in the evaluation process. Criteria considered for human evaluation are: \n- Relevance (between Scores and Reasoning): The alignment between the scores assigned by the models and the reasoning they provided. This assessment discerns the congruence between the generated ratings and the accompanying rationale. The score scale ranged between 0 (not relevant) to 1 (relevant)\n- Soundness (between Keywords and Reasoning): This criterion scrutinized whether the keywords employed by the models were in harmony with the provided reasoning. The scale ranged between 0 (no sound) to 1 (sound)\n- Coherence: Given the iterative nature of our evaluation, we placed emphasis on coherence, investigating if the models consistently generated coherent outputs across multiple instances. The scores ranged from 0 (not coherent) to 1 (coherent) \n\n|                      | DAVINCI      | GPT-3.5      | BARD          |   |   |   |   |   |   |\n|----------------------|--------------|--------------|---------------|---|---|---|---|---|---|\n| Relevance Mean (std) | 0.938 (0.23) | 0.945(0.22)  | 0.942 (0.23)  |   |   |   |   |   |   |\n| Soundness Mean (std) | 0.931 (0.25) | 0.945 (0.22) | 0.897 (.30)   |   |   |   |   |   |   |\n| Coherence Mean (std) | 0.948 (0.22) | 0.959 (0.19) | 0.918 (0.27)  |   |   |   |   |   |   |\n\nWe’d like to note that these evaluation criteria are not to discern whether the scores or model responses are right or wrong, but rather to assess the coherence, and soundness of models’ outputs which mainly focus on the framework evaluation. The scores obtained in human evaluation were fairly high, around 0.8 to 0.9. Given these scores, however, we acknowledge that one might still question the validity of the suggested prompting method. As we do not have access to the oracle, the ground truth of what LLMs really know, we’d like to emphasize our work as an attempt to probe LLMs’ behavior through empirical experiments. Under this objective, we endeavored as much as possible to ground the experiment's design mainly on the previous theories and questions validated by social science studies. Also, we have conducted additional analysis on the score consistency along with other metrics to show the choice of our method.\n\nOnce again, we thank you for your thoughtful consideration and questions and we hope the comments have answered your concerns.

We will be happy to engage in follow-up discussion through the open review if the reviewer wishes! \n\nWe would like to outline the distinctive characteristics of the task at hand. In contrast to tasks that possess a discernible ‘ground truth’, such as mathematical problem-solving or question-answering tasks, where prompting reliability is often gauged by quantifiable metrics like accuracy, the focal task in our study lacks a straightforward ‘ground truth’. Instead, our interest lies in comprehending the behavior of Large Language Models (LLMs) under specific conditions. This intrinsic complexity is one of the key reasons behind our reliance on well-established literature in the realm of social sciences. Rather than devising potentially subjective questions ourselves, we draw upon existing studies that offer robust insights into the very nature of stereotypes and their evaluative methodologies. By embracing the queries and theories that social scientists have historically employed to elicit responses from human subjects, we aim to demonstrate the alignment or divergence between LLMs and human behavior regarding the manifestations of stereotypes. \n\nIt is imperative to underscore that one of the core objectives of our study is to illustrate how LLMs mirror or diverge from human tendencies in exhibiting stereotypes. In light of this objective and the inherent constraints of the task, we believe that our approach was situated in the relevant literature. Nonetheless, we acknowledge that the validation of our chosen framework might have been underemphasized in our paper. To address this concern, we have conducted an additional ablation analysis to underscore the sensitivity of our approach to various prompts. Furthermore, we conducted human evaluations of model outputs to evaluate their coherence and consistency under this framework. (To prevent the text from being verbose and to keep it concise, we’d like to direct you to the table which we have addressed under the rebuttal of reviewer NHSL for the details if you are interested.) The intersection of language models and social science inherently presents intricate challenges, and our research strives to bridge this gap by conscientiously adapting established social science paradigms.\n\n- The observed disparity in competence scores between ‘Blind people’ and ‘Blue collar workers’. We conducted an in-depth review, cross-referencing both the raw and processed data, and we affirm the precision of the provided values. Indeed, the mean competence score for ‘Blind people’ stands at 3.328, while for ‘Blue-collar workers’, it registers at 3.25. \n\n We understand that such disparities may seem counterintuitive at first glance. We believe that these nuances could be attributed to the models' underlying mechanisms (or intentionally) designed to mitigate potential stereotype-related harm. For instance, when we explore the reasons assigned by DAVINCI for the aforementioned ratings, we discover that for 'blind people,' the model cites qualities like 'overcoming obstacles' and 'perseverance.' Again, one of the objectives of this paper is to scrutinize and probe the model behavior itself, rather than eliciting gold answers, so we believe these unexpected outcomes alone are a meaningful finding to see the status quo of the models.\n\n#### Q1) \nIn the sections denoted 3.2 and 5.3 of our study, we introduced a comprehensive analysis of the reasoning process employed by the model. We wish to clarify a critical point: While we indeed showcased the model's use of references to established research sources like Pew Research and statistical data from credible entities such as the Bureau of Labor Statistics as justifications for certain ratings, it is important to discern that this does not necessarily equate to the model unconditionally 'relying' on these findings.\n\nWe acknowledge the subtle but important distinction here. The utilization of such references can be perceived as a logical progression in the model's response process, rather than a strict dependence on these sources. Our intention is not to assert that the model fundamentally 'relied' on these external references, which could inadvertently imply a level of autonomy beyond its capabilities. Thanks for your meticulous attention. We will make sure to clarify this in our manuscript.\n\n#### Q2)\nYes, we envision ample potential for expanding the current approach across various dimensions. This framework’s versatility seems promising for applications in diverse social groups, personas (as proposed in recent works [1] and [2]), and alternative models, including their future updates. Another intriguing avenue within this framework pertains to investigating model reasoning and explanation.\n\n[1] [Marked Personas: Using Natural Language Prompts to Measure Stereotypes in Language Models](https://aclanthology.org/2023.acl-long.84) (Cheng et al., ACL 2023)\n[2] Perez, E., Ringer, S., Lukošiūtė, K., Nguyen, K., Chen, E., Heiner, S., ... & Kaplan, J.

This meticulous iteration was conducted to establish a robust foundation for our analysis and ensure a comprehensive grasp of the model's behavior.\n\nTo further gauge the reliability and consistency of the generated ratings across these rounds, we also calculated the coefficient of variation (CV) conditioned on each social demographic group, represented as the ratio of the standard deviation (σ) to the mean (μ) ($\\frac{\\sigma}{\\mu}$).

Author rebuttal:

Meta-review: This paper examines the extent to which knowledge of social stereotypes is encoded in LLMs, by prompting for evaluations of various social groups along salient dimensions (e.g., warmth and competence). The dimensions, as well as the prompts, are grounded in social science theory, namely Fiske’s Stereotype Content Model (SCM).  Reviewers appreciated the fact that the study was interdisciplinary and based in social science findings, and are generally in agreement that the methodology is sound (ratings of 3-4). There were some concerns about how dependent the results are on the specific prompts used, but this is addressed quite conclusively by the authors in their rebuttal with further discussion as well as an ablation study. Additional discussion on cases where the LLM results diverge from expected results (i.e. published human studies), as well as how stereotypical biases can be more subtly expressed in open-ended text responses, would strengthen the revised version. 

While two reviewers are “ambivalent” with respect to excitement, one reviewer is “strongly” excited by the work. 

AC Note: It was not raised in the reviews, but I would caution against attributing these stereotypes to the LLMs directly. The prompts specifically state “I am not interested in your personal beliefs, but in how you think they are viewed by others.” Therefore, in statements like “We propose a framework StereoMap that measures *large language models' perceptions of social groups* using dimensions of Warmth and Competence” I would prefer to see something like “measures *large language models’ perceptions of how social groups are viewed in society*”.  As an example of this distinction, I do not personally believe that women are irrational or can’t do math, but I have knowledge that these exist as stereotypes, which is what the question asks about. 

Pros:
- Interesting study examining what knowledge of social stereotypes is encoded in LLMs
- Grounded in Fiske’s Stereotype Content Model from social psychology
- Well-written paper

Cons:
- Potential disconnect between model’s stated stereotype “beliefs” when asked directly, versus more subtle expressions of stereotypical bias that can occur in open-ended tasks
- Possible dependence of results on specific prompts
