Jordan Peterson is a mixed bag; a little good, but a lot of bad.
The good: Some of the rules from his "12 rules" are legitimately good advice that I wish I had embraced sooner in my life.
* "Treat yourself like you are someone you are responsible for helping." (this is just good advice)
* "Compare yourself to who you were yesterday, not to who someone else is today." (mixed bag on this; a shoulder chip was a great motivator and learning that I'm not an imposter and never was has made me healthier but it's harder to motivate myself on work I'm not interested in),
* "Tell the truth – or, at least, don't lie." (I lied to myself a lot when the facts didn't support my beliefs; that was a mistake).
* "Assume that the person you are listening to might know something you don't." (I started learning much more quickly when I realized that I didn't know everything).
The bad: Peterson doesn't live up to his own rules and confidently asserts expertise in areas far outside of his area of knowledge and when pressed he'll serve up some word salad variation of the absolutely mind-destroying (for young minds) position that "there is no right answer/it's impossible to know what's true so you can ignore that evidence that contradicts your beliefs" (paraphrasing based on things I've heard him say on climate science, epistemology, science, biology, etc).
Also, he really likes pushing some pretty racist or offensive theories when far more plausible explanations exist without being grotesquely racist. For example, in this clip [0], Peterson and Stefan Molyneux (a deplatformed eugenicist, as you may infer from the clip) assert genetic are the explanation for differences observed in IQ testing when grouping by race. Peterson just asserts that genetics are the cause of the measured difference, even though that theory is contradicted by many studies of twins [1] that show socioeconomic status has far more explanatory power than genetics do. Further, the difference in socioeconomic status by race is a direct consequence of explicitly racist federal housing policies [2] (seriously, ctrl+f through this underwriting manual for the string "racial"; it's explicit about the intention to push black people into ghettos far from economic opportunity, while creating economically prosperous and racially homogeneous neighborhoods for white Americans that have natural defenses against "infiltration of inharmonious racial groups", all by only underwriting mortgages for homes in racially homogeneous neighborhoods located near abundant economic opportunity). Why would Peterson assert some races are genetically inferior when the facts invalidate that hypothesis and much more explanations that haven't been refuted by reality exist?
TL;DR: Peterson is not a good role model. If you need a role model for coming into adulthood, you can do much better than Jordan Peterson.
