The science behind our polarization.

I am pretty sure many of you, no matter on which side of political spectrum you reside, are puzzled why we became so polarized. I found a very interesting interview on Farid Zacharia's GPS. Vox Editor-at-large Ezra Klein joins Fareed to discuss his new book, "Why We're Polarized", & just how hardwired humans are to divide between "us" & "them". Very interesting, I definitely have to buy this book! See for yourself and enjoy!
