When it's not an obvious lookup/answer, is chatgpt just a contrarian now?

My idea is at the crossroads of stats 101, psychology, and game-playing agents (I have graduate degrees but this is original research)

Asked chatgpt to check my work regarding logic behind an idea and it said I'm wrong. In follow-up where I tried adding more detail it seemed deadest not actually agreeing with me like a cranky professor who'd always find a reason to give half credit.

Tossed it into gemini and thinking mode out comes Gemini said "You've hit on a fascinating intersection of..." "Your logic holds up..."

Asked Grok on a whim and "Yes, your reasoning is solid and aligns with the underlying..."

Does anyone have a similar experience?
