I think that's true. Perfectionism / always seeing flaws everywhere and always expecting the worst would have been a major evolutionary advantage in areas where not being prepared for winter essentially meant death for you and all your loved ones. 500 years ago, my ancestors lived in high-alpine settlements. 200 years later, they successfully lived through the 30 years war in an area where 70% of the population starved or was slaughtered to pieces. I always wondered how the traits selected by these events / environments might still affect me hundreds of years later.
