Will you change your mind?
+Buddhini Samarasinghe wrote about http://edge.org's annual question:
What Have You Changed Your Mind About? Why?

I thought about some of the hot-button topics and how you often can't change people's mind, even with overwhelming evidence. There are three things working against changing someone's mind.

✿Confirmation Bias - the tendency to favor information that supports your existing view.

✿Cognitive Dissonance - action that contradicts reasoning, e.g., continuing to smoke when you agree it is unhealthy.

✿Motivated Reasoning - accepting information that supports what you already believe and giving extra scrutiny to information that is against what you believe.

Here's a good blog to summarize these three concepts.
Psychology’s Treacherous Trio: Confirmation Bias, Cognitive Dissonance, and Motivated Reasoning
By Sam McNerney 2011

There is a biological component too. Chris Mooney writes that emotion kicks in before you have a chance to reason. Evolution has lead animals to react quickly for survival. It makes sense that when we react quickly, we rely on what we believe first.

The Science of Why We Don't Believe Science
How our brains fool us on climate, creationism, and the vaccine-autism link.
By Chris Mooney 2011 h/t +Marjolein Caniels

The Mooney piece has many examples of the treacherous trio. I would suggest reading the McNerney blog first. This isn't my area of expertise so I'm hoping +Zuleyka Zevallos or +Chris Robinson can chime in.
