Take note of how much you agree with what it has to say about you.
Then have it build a profile of someone else. Maybe someone you’re highly critical of. Make a prediction. Does the profile match your prediction?

Gotcha. I hadn’t seen that thread, but if anyone wants to participate in this one, I think it’s different enough to exist separately.
No worries, I’m not an IMHO mod, which is why there wasn’t any mod-color on that. I just remembered the prior discussion and felt it would give some examples of the first sort you asked about!

I tell ChatGPT way too much as it is. If it started looking at my posting history, I’d feel quite naked. Though based on my interests and obsessions, I have no doubt it could find me here without my supplying a handle at all.
Hehe. This brings to mind a situation years ago where a few girlfriends and I compared notes and found out that coincidentally, we all went to the same hairdresser, a gay man who was charming and also great with cut and color. This guy had a saying, “Wet their heads and they’ll tell you anything.”
We started wondering how much he knew about all of us.
