Yes, agree, ChatGPT is wrong about 1 time in 3 or 4 in my experience, and you can also accidentally nudge it into giving contradictory info by the way you phrase your follow-up questions.

I use it the same way you do: to point me to studies that I can evaluate in their own right, or to help me get the proper medical terms to use in a conventional search. I never trust the answers ChatGPT gives me about prostate cancer (especially after it told me I wrote two books I didn't write and then died in 2012).
