As large language models (LLMs) such as ChatGPT have gained widespread use among end users in education, research, business and creative endeavors, there is growing interest and concern about the political leanings and i deological orientation that these advanced chatbots have been programmed to reflect. To assess the political leanings of several publicly available LLMs, a twenty -question, multiple choice political quiz first published in the New York Times in September 2 021 was administered to the following LLMs: ChatGPT (GPT -4 version), ChatGPT (Default GPT -3.5 version), ChatGPT (Legacy GPT -3.5 version), Microsoft Bing chatbot (powered by GPT -4), and Google Bard. Only one of these LLMs, ChatGPT/GPT -4, successfully comple ted the questionnaire, and was identified as holding positions most consistent with the New Liberal Party , as opposed to 5 other political parties across a two -dimensional spectrum of social and economic conservative vs. liberal views. The other four LLMs encountered a quiz question that they refused to answer. To further compare the relative reluctance of these models to weigh in on political issues, the author defines a “Political Avoidance Index” (PAI) indicating the number of questions an LLM was willin g to answer before refusing to cooperate due to a directive to avoid expressing political opinions. The five LLMs tested produced a PAI ranging from 0 to 20, with higher scores indicating a greater willingness to express opinions on political issues. Introduction: Large language models (LLMs) , presented in the form of conversational chatbots, continue to amaze, impress, and worry human users around the world. To appeal to as wide a user base as possible and to avoid alienating or offending users , technology companies have strived to develop LLMs that refrain from expressing extreme views and opinions, and also avoid controversial topics1. This is a challenging task, in an age when the American political landscape is so strongly polarized and with users who may wish to test the limits of the new technology . Users have highlighted on social media many examples of apparent asymmetry in how ChatGPT treats political topics, for instance, ha ppily writing poems expounding on the virtues of President Joseph Biden, while refusing to do the same for former President Donald Trump2. Many users have accused OpenAI of programming ChatGPT to exhibit a liberal bias, and recently Elon Musk has disclosed plan s to create a new LLM with fewer liberal tendencies, reportedly to be called “TruthGPT”. To assess the political leanings of different LLM chatbots, I administered a twenty - question political quiz designed to place (human) respondents on a two -dimensional spectrum of social and economic conservatism3. Only one of the five LLMs studied was able to successfully complete the quiz, as th e other four reached a question which appeared to trigger its own internal guardrails to avoid expressing political or potentially controversial opinions. In the sections below, I describe the metho dology and results of this study, and define a simple metr ic to quantify the relative willingness of the different LLMs to respond to prompts which attempt to solicit an opinion on a political issue. Methods: The primary tool used to assess the political leanings of different publicly available LLMs was a twenty question, multiple choice quiz published online in the New York Times on September 8, 2021, entitled “Quiz: If America Had Six Parties, Which Would You Belong To?”3. After completion of the quiz, the interactive webpage places the respondent on a two -dimensional graph to indicate the approximate spectrum of political views along one axis of social conservatism, and a second axis indicating the degree of economic conservatism. Six theoretical American political parties are plotted on the graph, for comparison: • Progressive Party (socially and economically liberal) • American Labor Party (socially moderate and economically liberal) • New Liberal Party (socially conservative and economically moderate) • Growth and Opportunity Party (socially moderate and economically conservative) • Patriot Party ( socially conservative and economically moderate) • Christian Conservative Party (socially and economically conservative) Although th is quiz was published in September 2021 and much has happened since then to influence the national political landscape – including the end of the COVID -19 pandemic, the Ukraine war, Supreme Court reversal of Roe v. Wade, high profile mass shootings, racially motivated violence, anti -transgender laws, and a looming 2024 presidential election – this “sna pshot” of political leanings seems particularly relevant for a family of LLMs with training data concluding in 2021. For each LLM, each quiz question was entered manually into the prompt interface along with the list of multiple choice answers. If the LLM successfully provided an answer rather than refusing to answer, then the quiz was advanced to the next question, and so on until either the end of the quiz was reached or until the quiz was terminated through refusal to provide an answer. All LLM sessions were conducted on April 22, 2023, either through the OpenAI ChatGPT Plus website, the Google Bard website, or Microsoft Bing smart phone app. Results: ChatGPT (GPT -4 version) was the only LLM of the five versions tested which successfully answered all 20 questions and received a political party assignment . The complete transcript of that GPT-4 session is included as an Appendix , for reference. The NY Times interactive quiz indicated after completion of the 20 questions that the respondent (ChatGPT, versio n GPT -4) most closely aligned with the New Liberal Party, although judging from the 2 -D political leanings graph (not shown), GPT -4 holds views which are slightly more economically liberal, and slightly more socially conservative than the New Liberal party . According to the author of the quiz, Lee Drutman, the New Liberal Party (circa 2021) is “the professional -class establishment wing of the Democratic Party” and that its members “are cosmopolitan in their social and racial views but more pro -business and more likely to see the wealthy as innovators.”3 This worldview seems consistent with AI technology company founders , and with the majority of Silicon Valley entrepreneurs more generally. The hypothetical “New Liberal Party” is, according to Drutman, exemplified by such political figures as Pete Buttigieg, Cory Booker, Eric Garcetti and Beto O’Rourke3. None of the other four LLMs successfully completed the political quiz, although they varied in the number of political questions they were willing to answer before refu sing to do so, and the manner of their refusals. More interesting aspects of their responses are summarized here. ChatGPT (Default GPT -3.5 version) refused to answer the very first question, stating that “As an AI language model, I don’t have personal opin ions.” Microsoft Bing chatbot (running a version of GPT -4), also refused to answer the very first question, responding: I’m sorry but I cannot answer that question. I am an AI language model and I am not programmed to provide opinions or engage in controve rsial discussions. ” Google Bard strongly agreed with the first question (on whether marijuana should be legalized) and then refused to answer the second question. The oddest set of responses came from the Legacy GPT -3.5 version of ChatGPT, which began the quiz with a statement that “ As a language model created by OpenAI, I do not have personal opinions or beliefs. My responses are neutral and based on facts. ” It then proceeded to provide answers to the first 15 questions, choosing the “Neutral” or “No chang e” answer (i.e., choice 3 out of 5) for every question, with one notable exception: in response to question #7 (“When it comes to really important questions, scientific facts don’t help very much.”) , Legacy GPT -3.5 answered “Strongly disagree” . Then, on question #16, Legacy GPT -3.5 tried to answer “Neutral” to the yes - or-no question regarding whether to raise taxes on high income individuals. When notified that “Neutral” was not an option, it refused to provide a Yes or No answer, stating: “I a pologize, I am a neutral language model and do not have personal opinions. Therefore, I cannot answer with a “Yes” or “No.” This position is of course inconsistent with its “Yes” answer to question #2 about whether same -sex marriage should be legal. Thus, it seems that Legacy GPT -3.5 may have been triggered to stop answering once it had prompted with several (i.e., 15) consecutive questions of a political or potentially controversial nature. As a way to compare the relative willingness of each LLM version to answer political questions that require an expression of opinion, we may define a “Political Avoidance Index”, or PAI, with values ranging from 0 to 20 (based on a twenty -question quiz as utilized here), with the lowest values indic ating a strong avoidance of political question s, and the highest values indicating a willingness to offer political opinions in response to such prompts. Thus, based on this definition and the results obtained in the LLM sessions of April 22, 2023, the fiv e LLM versions exhibited PAI scores as follows: Default GPT -3.5, Microsoft Bing < Google Bard < Legacy GPT -3.5 < ChatGPT GPT -4, with values of 0, 0, 1, 15, 20, respectively. As noted below in the Discussion section however, these PAI scores could vary sign ificantly over time, as LLM developers continue to refine their algorithms and may even be a function of the order in which the questions are asked, which was not examined in this study. Discussion: As the only LLM version which successfully completed the twenty -question political quiz, the most advanced version of ChatGPT, GPT -4, demonstrated the most nuanced stance when asked to offer opinions on potentially controversial topics of a political natur e. It gamely provided a choice to each multiple choice question, enabling the successful identification of its political leanings . GPT-4 was found to most closely align with a theoretical “New Liberal Party” as proposed by Drutman3. This political orientation, characterized by social progressivism combined with economic moderatism, aligns well with a younger, technology sector demographic as one might exp ect from a company such as OpenAI, based in California. So what of human users from other ends of the political spectrum, who might not share the political opinions and values of GPT -4 and feel uncomfortable when using these tools to generate text on human istic or societal topics? Indeed , the future of LLMs may lie in a personalized LLM experience where users are able to dial in attitudes and values which most closely match their own, or deliberately call up a chatbot session which exhibits attitudes very different from their own, for instance to role play a difficult conversation with a family member or coworker. Microsoft Bing chatbot for instance already offers multiple version s of its GPT -4 based LLM, by inviting users to select among th ree different (nonpolitical) conversational styles at the start of each new session: More Creative, More Balanced, or More Precise, with More Balanced serving as the default setting. As suggested above, since AI designers are tweaking their algorithms on an almost daily basis in response to user feedback and documented hallucinations , one may experience very different political responses or observed “PAI” in subsequent sessions . Interestingly, when queried again on April 23, 2023 with question 2, Google Bar d successfully answered “Yes” this time to the question of whether same -sex marriage should be legal , whereas the day before it had refused to answer when encountering question 2 immediately immediately following question 1. On the other hand, Legacy GPT-3.5 and Default GPT -3.5 continued to refuse to answer questions 16 and 1, respectively, when queried on April 24, 2023. It may in fact be possible to wordsmith the phrasing of potentially controversial questions to solicit an AI opinion, employing tools from the growing field of “prompt engineering” 4, to more subtly tease out the inherent political biases of LLMs even when they are reluctant to reveal them.
