Why is Everyone So Irrational When it Comes to Politics?
Michael Huemer, from CU-Boulder has a Ted-Talk, article, and a book that deals with these topics. The question addressed in the paper, is whether persistent disagreement is explained by something like (i) ‘lack of information’, (ii) ‘miscalculation’, (iii) ‘divergent values’, or is it a kind of (iv) ‘irrationality’?
Here is the paper (not too long): http://www.owl232.net/papers/irrationality.htm
His article argues that it is irrationality, not lack of evidence, divergence of values, or even a lack of information, that explains our many divisive disagreements. I think his arguments are persuasive, which pushes us (people in general) to consider how we can be more rational.
His book on Political Authority is worth a read
