I think this board is a microcosm of human behavior. Some people tend toward optimism, some toward pessimism. I posit there are few areas where this is more blatant than the weather. It's something that nobody can do a damn thing about and really unmasks our inherent biases.
I tend toward "defensive pessimism". Eternal optimists annoy the fock out of me. But it's like an introvert vs an extrovert. Neither is inherently wrong or bad.
And let's face it, the pessimists have gotten it right for a while now.
