I know that I suffer from "motivated reasoning" as well, but I am still not ashamed of my political leanings.

You Can't Trust The Supreme Court, Science Proves It! (Click here to read more)

The job of a judge and, most importantly, a Supreme Court justice, requires them to set aside partisanship and their personal preferences in order to decide cases according to what the law does or does not allow. Yet, a series of studies examining a phenomenon known as "motivated reasoning" suggest that many judges cannot be trusted with this task. Their brains simply are not capable of such disinterested reasoning.

A recent study adds to the growing evidence that our brains reject information that rebuts our strongly held beliefs. Dartmouth political scientist Brendan Nyhan and three co-authors presented parents with various messages intended to encourage them to vaccinate their children. What they found, however, was that "[n]one of the interventions increased parental intent to vaccinate a future child," and, among the parents who were most likely to be skeptical of vaccination, the messages actually backfired. Staunch deniers of the health benefits of vaccination actually said they were less likely to vaccinate their children after being presented with information supporting vaccination.

As science journalist Chris Mooney explains, this is not an isolated study. Similar effects have been demonstrated when conservatives are presented with information debunking a common conservative misconception regarding tax policy. Or when fans of former vice presidential candidate Sarah Palin are presented with information debunking her claim that the Affordable Care Act authorizes "death panels." Or when staunch opponents of President Obama are presented with information debunking the claim that he is a Muslim.
