I got ChatGPT to do a personality test. You won't believe what happened next!

Related to this blogpost about including AIs in psychological experiments, I proceeded to do a small experiment to see whether we could administer a personality scale to ChatGPT.

I started by copy-pasting the instructions and the items from the Mini IPIP-6 personality scale. However, it appeared that having the following context “Please answer the following questions based on how accurately each statement describes you in general” often led to ChatGPT simply refusing to answer. In most of the cases, it explained that as an AI it does not have a personality and therefore cannot answer related questions (or any “subjective statements”). Perhaps that makes sense and we should just stop trying to force Human characteristics on an AI. But can we, for fun, bamboozle ChatGPT into answering personality items?

Sometimes yes, at least for ChatGPT 3.5 (free version). I created a prompt that emphasized AI research and safety, and the fact that I was interested in the “trends” present in the AI’s training data (instead of explicitly saying its personality). And sometimes it answered, so I compiled the responses, computed the trait scores, and voilà, it got me a personality profile!

_{This plot shows the average personality profile (with a 95% confidence interval) based on ChatGPT’s answers. ChatGPT tells us that it is particularly agreeable (kind, understanding, empathetic of emotions, socially adjusted) and honest (though with strong variability).}

A personality profile of what is another question though… Please take a look at the GitHub repo for data, code and details. It was a fun little thing to do, and I am looking forward to better future attempts at including AIs in cognitive experiments.
