interesting! the reverse of what i was mentioning. it seems to flip, then, doesn't it? optimistic in youth -> cynical in old age
cynical in youth -> optimistic in old age
perhaps people just balance out their preferences as they get older and experience more things. sort of like what the MBTI mentions about personal growth: people take on the positive attributes of their shadow functions as they grow up. an INFJ would become less intuitive, more pragmatic, more down to earth and extroverted like a healthy ESTP as they get older.
