This includes parents and upbringing, making it abundantly clear that parents don’t leave a lasting impact on who we grow up to be. These are towards what I’m calling the “75-0-25 or something” rule, which echos Satoshi Kanazawa’s “50-0-50 rule” summarizing behavioral genetic research, only more accurately so. This “75-0-25 or something” rule means the following:
