I agree that past performance is not a sure indicative of future results, and that the recency bias can make some bettors place risky bets which they think are "safer" than they really are. But I don't totally agree with your sentence below:
-snip-
In sports betting, this can hinder you from making rational decisions. Sometimes, people fall for short clips cut specifically to make an athlete look good or cool. This is very common on reels or tiktok.
Sometimes, and especially when results depend on too many variables, more information doesn't mean better decisions. So those who don't do a thorough analysis but instead base their decisions in the good look of an athlete or his/her good recent performance may be right in the end, and have better results than more conscientious bettors.
