Reddit user proves ChatGPT can deliver accurate IQ tests and personalized life advice

In a viral Reddit post, user KLC_W detailed how they asked ChatGPT to design a custom IQ test, explicitly requesting something broader than standard tests. The AI generated four categories of questions, which the user answered while tracking their response times. They then received a detailed analysis of cognitive strengths and weaknesses, along with an IQ estimate that — to their surprise — exactly matched the result from a professional psychologist's evaluation.

Taking the experiment further, the user asked ChatGPT to leverage its new understanding of their mind to improve their life. The AI offered a curated list of book recommendations tailored to their thinking style, parenting advice for raising a child with similar traits, and even suggestions for online communities where they might find like-minded people — a particularly valuable feature for the user, who lives in an area where their open-mindedness isn't appreciated. The response underscores ChatGPT's growing ability to act as a personalized life coach, using conversational data to provide bespoke guidance across domains like self-improvement, learning, and social connection.
