Dear Humans, Please Help Eachother To Subside The Argumentative Theory Of Reasoning

One the best research papers I ever read - Why Do Humans Reason?. Now, the authors Hugo Mercier and Dan Sperber propose a simple theory to subside that dissonance - check it out on Edge:

"Now, the authors point out that we can and do re-use our reasoning abilities. We're sitting here at a conference. We're reasoning together. We can re-use our argumentative reasoning for other purposes. But even there, it shows the marks of its heritage. Even there, our thought processes tend towards confirmation of our own ideas. Science works very well as a social process, when we can come together and find flaws in each other's reasoning. We can't find the problems in our own reasoning very well. But, that's what other people are for, is to criticize us. And together, we hope the truth comes out."



I think Metacognition to a certain level would also help to overcome that dissonant reasoning. 
Summary of the original paper:

"Reasoning was not designed to pursue the truth. Reasoning was designed by evolution to help us win arguments. That's why they call it The Argumentative Theory of Reasoning. So, as they put it, "The evidence reviewed here shows not only that reasoning falls quite short of reliably delivering rational beliefs and rational decisions. It may even be, in a variety of cases, detrimental to rationality. Reasoning can lead to poor outcomes, not because humans are bad at it, but because they systematically strive for arguments that justify their beliefs or their actions. This explains the confirmation bias, motivated reasoning, and reason-based choice, among other things."


This paper had a huge impact on my life; it more or less killed that polemic inside me.
