Is it optimising for all users? And assuming people thumbs up the correct info. I wonder what accuracy percentage we are looking at there. ChatGPTs responses are so confident when wrong I fear people will just give it a thumbs up when its wrong. (This is if how I understand the feature you mention is working)
I am not talking about accuracy. Only experts can determine factuality.
I am talking about relevance or returning what I asked. If I ask for reviews for SaaS product, Google will usually return a rival vendors’ biased review.
If ChatGpt search returns a review written by “the professional association of xxx developers” or another unbiased site, I will give it a thumbs up. I believe other people will do the same.
