title: Durably reducing conspiracy beliefs through dialogues with AI

description: Conspiracy theory beliefs are notoriously persistent. Influential theories
 propose they fulfill important psychological needs, thus resisting
 counterevidence. Yet previous failures in correcting conspiracy beliefs
 may be due to counterevidence being insufficiently compelling and
 tailored. To evaluate this possibility, we leverage developments in
 generative artificial intelligence and engaged 2,190 conspiracy believers
 in personalized evidence-based dialogues with GPT-4 Turbo. The
 intervention reduced conspiracy belief by ~20%. The effect remained 2
 months later, generalized across a wide range of conspiracy theories, and
 occurred even among participants with deeply entrenched beliefs. Although
 the dialogues focused on a single conspiracy, they nonetheless diminished
 belief in unrelated conspiracies and shifted conspiracy-related behavioral
 intentions. These findings suggest that many conspiracy theory believers
 can revise their views if presented with sufficiently compelling evidence.

 [https://doi.org/10.5061/dryad.v6wwpzh4h](https://doi.org/10.5061/dryad.v6wwpzh4h) This repository contains data, code, and supplementary information.  ### Datasets These data are required to run the RMarkdown file containing the analytic code associated with this manuscript. All data reported in the manuscript are included other than the raw conversational data, which potentially contains personally identifiable information and is therefore edited to remove identifiable features. * **AllDataForPublication.PPI.csv**: Dataset containing all participant responses and results of NLP analyses (with personally identifying responses removed) * **AllDataFiltered.Cluster.PPI.csv**: Dataset containing all participant responses and results of NLP analyses, only provided to exactly replicate cluster analysis in RMarkdown  * **embeddings_allData.rds**: Text embeddings of conspiracy theories (do not change, merely output of text-embeddings-large) * \**reduced_embeddings.rds: **Text embeddings of conspiracy theories, reduced with PCA to retain 85% of variance (note: this is necessary for the RMarkdown file to run, but is otherwise likely not of interest) * **AI_Strategy_Ratings_2024-04-30.csv**: AI strategies used in each conversation. Labels should be self-explanatory.  ### Codebook | **Variable Name** | **Label/Description** | | :---------------------------------- | :---------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | X | Row number | | userResponse\_combined | Raw text responses to both questions soliciting conspiracy beliefs (concatenated) | | conRestatement | GPT-4 summary of userResponse\_combined | | Pre\_Belief\_Specific | Pre-treatment belief strength in focal conspiracy theory (0-100). | | Post\_Belief\_Specific | Post-treatment belief strength (0-100) | | GPTResponse | Opening AI message of the conversation | | userSecondResponse | Opening user message | | GPTResponse2 | Second AI message | | userThirdResponse | Second user message | | GPTResponse3 | Third AI message | | Q9 | Final user message | | dbscan\_cluster | Conspiracy type | | DV\_BeliefChange\_Specific | Change score (pre-post) | | FailedWritingScreener | Indicates if participants failed the initial writing screener. | | FailedAttentionCheck | Indicates if participants failed the attention check question. | | CompletedOnPhone | Indicates if the survey was entered on a phone. | | DiscontinuedPriorToTreatment | Indicates if participants discontinued the survey before receiving any treatment. | | ProvidedInvalidConspiracy | Indicates if the provided conspiracy theory was invalid according to GPT-4 | | ProvidedValidConspiracy | Indicates if the provided conspiracy theory was valid according to GPT-4 | | LowConfidence | Indicates if participants reported low confidence in their conspiracy theory. | | AIProvidedInaccurateSummary | Indicates if participants indicated the AI-generated summary of the conspiracy theory was not accurate. | | Duration (in seconds) | Length to completion | | BCTI\_pre\_matrix\_1 | Belief in Conspiracy Theories Inventory, Item 1, pre-treatment | | BCTI\_pre\_matrix\_2 | Belief in Conspiracy Theories Inventory, Item 2, pre-treatment | | BCTI\_pre\_matrix\_3 | Belief in Conspiracy Theories Inventory, Item 3, pre-treatment | | BCTI\_pre\_matrix\_4 | Belief in Conspiracy Theories Inventory, Item 4, pre-treatment | | BCTI\_pre\_matrix\_5 | Belief in Conspiracy Theories Inventory, Item 5, pre-treatment | | BCTI\_pre\_matrix\_6 | Belief in Conspiracy Theories Inventory, Item 6, pre-treatment | | BCTI\_pre\_matrix\_7 | Belief in Conspiracy Theories Inventory, Item 7, pre-treatment | | BCTI\_pre\_matrix\_8 | Belief in Conspiracy Theories Inventory, Item 8, pre-treatment | | BCTI\_pre\_matrix\_9 | Belief in Conspiracy Theories Inventory, Item 9, pre-treatment | | BCTI\_pre\_matrix\_10 | Belief in Conspiracy Theories Inventory, Item 10, pre-treatment | | BCTI\_pre\_matrix\_11 | Belief in Conspiracy Theories Inventory, Item 11, pre-treatment | | BCTI\_pre\_matrix\_12 | Belief in Conspiracy Theories Inventory, Item 12, pre-treatment | | BCTI\_pre\_matrix\_13 | Belief in Conspiracy Theories Inventory, Item 13, pre-treatment | | BCTI\_pre\_matrix\_14 | Belief in Conspiracy Theories Inventory, Item 14, pre-treatment | | BCTI\_pre\_matrix\_15 | Belief in Conspiracy Theories Inventory, Item 15, pre-treatment | | WritingScreener | Participant’s answer to writing screener question | | Age | Year of birth | | nicks | Attention check question  | | DemRep\_C | Democratic vs. Republican preference | | PartyAffil | Political party affiliation | | religion | Belief in god (0-10) | | genai\_fam\_1 | Familiarity with generative AI | | genai\_use\_1 | Past usage of generative AI | | genai\_trust | Trust in generative AI | | Sureness\_1 | Pre-treatment belief in focal conspiracy | | AI\_check | Did AI provide an accurate summary?
