3.  Where is the posterior medial prefrontal cortex? What role did it play in pointing to confirmation bias in people guessing home values?

4.  The second study described in this story examines what is making the brain ignore what it doesn’t want to hear. What was that?

5.  What is a magnetoencephalogram and how was it used in the second study?

6.  Alice Atkin says the two papers described in this story “speak to each other.” What does she mean by that?

After Reading:

1.  Give an example of some issue where you or some member of your family has exhibited confirmation bias. Explain how it appears to have helped or hurt their dealing with issues?

2.  As the studies on housing values and dots show, you don’t have to have strong opinions about a subject to be susceptible to confirmation bias. If you know that about yourself (or some family member), how would you go about making yourself (or family member) less vulnerable?
