I would say that our brain is wired to react to direct threats and not long terms ones because the main cause of death was direct threats until not so long ago.

I would say that our brain is wired to react to direct threats and not long terms ones because the main cause of death was direct threats until not so long ago. And by natural selection, the ones reacting to direct threats survived. This is an hypothesis, I would be interested if there is research done on the subject.
