My experience (possibly biased by my model) has been that it's a generational difference. Based on the fourth turning model Boomers are 'Prophets' while Millennials are 'Heroes'. No one cares if a prophet correctly predicts seven weeks of great weather if they miss the one hurricane that wipes everything out. And no one wants to hear a hero (which, let's face it, is a polite synonym for 'cannon fodder') give a realistic assessment of the odds. So this model would predict Boomers are culturally pessimistic while Millennials are culturally optimistic (both to an irrational degree at times).

Which has been my actual observation - has anyone here had corroborating or counterfactual experiences?
