About the Blog

I shall post videos, graphs, news stories, and other material. We shall use some of this material in class, and you may review the rest at your convenience. I encourage you to use the blog in these ways:

--To post questions or comments about the readings before we discuss them in class;
--To follow up on class discussions with additional comments or questions.
--To post relevant news items or videos.

There are only two major limitations: no coarse language, and no derogatory comments about people at the Claremont Colleges. This blog is on the open Internet, so post nothing that you would not want a potential employer to see.

Confidence? I Don't Know About That...

Dilbert.com

Scott Adams is not kidding about the research. Psychologist Daniel Kahneman writes:
We often interact with professionals who exercise their judgment with evident confidence, sometimes priding themselves on the power of their intuition. In a world rife with illusions of validity and skill, can we trust them? How do we distinguish the justified confidence of experts from the sincere overconfidence of professionals who do not know they are out of their depth? We can believe an expert who admits uncertainty but cannot take expressions of high confidence at face value. As I first learned on the obstacle field, people come up with coherent stories and confident predictions even when they know little or nothing. Overconfidence arises because people are often blind to their own blindness.
