Aleph Big5 Synthetic
Disclaimer: this dataset is entirely synthetic. Every single comment was written by an LLM (either Opus5.5 or Haiku 4.5), and the dataset contains reddit-style comments, alongside the corresponding Big 5 score of the persona that the LLM used to generate the comment. Each commenter has a particular Big 5 profile, and their comments are supposed to indirectly reflect the profile.
This dataset contains text fragments (modelled on reddit comments), alongside its (artificial author persona's) corresponding Big 5 scores. It is meant to be used as supplementary data for any text-to-big5 regression models, but its use is not strictly limited to that. The reason why the relation between the two is not random is because the comments are meant to realistically represent what a person with a given Big 5 profile would sound like, at least according to the LLMs that generated it. Details below.
How it was made
- We generated Big 5 scores for each profile randomly, using the distributions found in AlephPsychometric.org 's collected user data
- Each profile got a randomly sampled persona: age bracket, occupation, two interests, and a writing-style instruction. Styles are conditional on traits passing a certain threshold, so for example the "blunt" trait only appears for profiles with ≤ 40 agreeableness.
- Each persona was generated in an independent API call, asked for 20–40
comments as replies to unseen threads, and forbidden from naming traits or
describing itself. Outputs were filtered for format and minimum length.
Generators are recorded per row in
instrument(llm:<model>).
Known limitations
- The comments were written by two different models, but both of these were made by Anthropic.
- It is highly likely that the models generated comments that lean heavily into stereotypes of particular Big 5 profiles, so profiles high in agreeableness may have a high tendency to use polite language for example.
- Subreddit names are model-invented and may not exist.
