Confirmation bias is our tendency to seek evidence that supports our beliefs and confirms our assumptions when we could just as well seek disconfirmation of those beliefs and assumptions instead. This is such a prevalent feature of human cognition, that until recently a second bias has been hidden in plain sight. Our past beliefs and future desires usually match up. Desirability is often twisted into confirmation like a single psychological braid - but recent research suggests that something called desirability bias may be just as prevalent in our thinking. When future desires and past beliefs are incongruent, desire wins out. - Show notes at: www.youarenotsosmart.com - Become a patron at: www.patreon.com/youarenotsosmart SPONSORS • The Great Courses: www.thegreatcoursesplus.com/smart • Dignity Health: www.dignityhealth.org/taketwomins • Blue Apron: www.blueapron.com/yanss
