I want you to read the true system of the heart, drafted by a decent man and published under another name. I do not want you to be biased against good and useful books merely because a man unworthy of reading them has the audacity to call himself the Author. Jean-Jacques Rousseau
The smartest groups, then, are made up of people with diverse perspectives who are able to stay independent of each other. Independence doesn't imply rationality or impartiality, though. You can be biased and irrational, but as long as you're independent, you won't make the group any dumber. James Surowiecki
