Some people develop their world-view up until their late teens/early twenties, then they spend the rest of their lives defending that world-view. Others adapt their views as they accumulate more information and experience. This leads to having to "change your mind" though, which can make the former type of person angry. If you keep changing how are they supposed to formulate ways to beat you in arguments?!
Some people at around 40 go "I was such an idiot at 20! now I know exactly what's going on"... without realising that they'll probably look back in another 20 years and think the same (I say this as a 42 year old dunce). I see the fractal parent of this in larger society - always looking back at the past and mocking how foolish people were. Every generation was more stupid than the one that came after it, their theories more ridiculous - right up until us. Finally we have it all worked out. Phew!
