Touting slogans such as 鈥淔acts have a well-known liberal bias鈥, people on the Left have made clear they see themselves as the true heirs and defenders of the Enlightenment. New research, however, shows that they鈥檙e just as deluded as everybody else.

In fact, they were willing to give up the chance to win money just to avoid the unpleasantness of hearing an opinion they disliked.

Sloppy thinking is at the root of many modern ills. We delve into nine key ideas that come naturally to us to find out why they are often so misguided
A meta-analysis of 41 studies recently published on the Social Science Research Network : there was no difference in partisanship between liberals and conservatives. As it turns out, 鈥渙pen-minded鈥 liberals are plagued by confirmation bias to the same extent as 鈥渃losed-minded鈥 conservatives.

Alternative realities
This shouldn鈥檛 come as a surprise to聽anyone who has followed politics in聽recent years.

Twisting science into a bludgeon for political opponents is a gross perversion of humanity鈥檚 best attempt at secular knowledge. Worse, it does grievous damage to the institution of science.
