An 11 minute TED talk provides insights into how people can get to the point of being so wrong, all the while thinking they are so right. It turns out motivated reasoning is to blame.
I first wrote about motivated reasoning in November of 2013 in a blog post titled Why Are So Many Christians So Un-Christian? One of the key points of the post is that people choose what to believe. Choice Theory proposes that we are always involved in the process of creating and maintaining a reality that works for us. Check out that post below –

Two other blog posts also commented on our being “right” and our having a direct pipeline to Truth.

Julia Galef, the TED talk speaker, explained the difference between a warrior mindset and a scout mindset. The warrior is driven toward one goal, to survive through defending or attacking, while the scout is driven to understand and to gain a complete and accurate picture of the facts. The book I recently completed, The Anatomy of Peace, explained the difference between a heart at war and a heart at peace. As choice theorists we can be thankful that more and more people are coming into an awareness of the human ability to create our perception of reality, and more importantly, our ability to choose a more effective reality.
