Will System 2 Ever Overtake System 1?

Us skeptics tend to be a strong lot that thinks that, eventually, we will overcome the infancy of the human race and wipe out every vestige of irrationality from the face of the Earth.  However, science, ironically, is not in our camp on this matter:

"System 2 evolved relatively recently. It’s the voice in our head – the narrator who never seems to shut up – that enables us to plan and think logically.  System 1, on the other hand, is intuitive, instinctual and automatic.

"--- science – the system of choice that many atheists and non-believers look to for understanding the natural world – is not an easy cognitive pill to swallow. Science is about correcting System 1 biases, McCauley says. We must accept that the Earth spins, even though we never experience that sensation for ourselves. We must embrace the idea that evolution is utterly indifferent and that there is no ultimate design or purpose to the Universe, even though our intuition tells us differently. We also find it difficult to admit that we are wrong, to resist our own biases and to accept that truth as we understand it is ever changing as new empirical data are gathered and tested – all staples of science. 'Science is cognitively unnatural – it’s difficult,' McCauley says. 'Religion, on the other hand, is mostly something we don’t even have to learn because we already know it.'

“'There’s evidence that religious thought is the path of least resistance,' Barrett adds. 'You’d have to fundamentally change something about our humanity to get rid of religion.' This biological sticking point probably explains the fact that, although 20% of Americans are not affiliated with a church, 68% of them say that they still believe in God and 37% describe themselves as spiritual. Even without organized religion, they believe that some greater being or life force guides the world."
