What makes people irrational thinkers?

[SlowCalculations]

I like to think I will believe in god(s) if presented with empirical evidence. None such has so far been forthcoming in recorded history.
That leads me to suspect it may not occur within what is left of my lifetime.

Oh, I also reject the notion that god(s) may be argued into or out of existence.  For me, demonstration of the existence of gods must be falsifiable. Period

The criteria you use make your conclusion inevitable. 

If the OP is correct, it would be wise to question these criteria.

What does  demonstration of the existence of gods must be falsifiable.  mean as a sentence?

One thing I have learned from teaching math is that logic isn't a natural way of thinking. Even those who have an aptitude have a LOT of difficulty when it comes to coming up with and writing logical proofs. Although we like to claim that logic is the 'laws of thought', in reality, most conclusions most people arrive at are not found through logic.

Instead, people usually have intuitions that they then use some sort of 'reasoning' to justify. But the reasoning is usually NOT the reason they believe. it is the way they justify their intuitions. And their beliefs are based on those intuitions, not on logic or reasoning.

Interesting, i had a teacher who once told me people are not born critical thinkers (I'm undecided) but i like to think they just don't have the tools yet. 
Would you agree or disagree just me being curious?
