Key Points

Here is a list of the 26 principles I will be covering this semester. These are just an introductory sampling of the ways that people are fooled into believing things that are not (or not likely to be) true. As the semester wears on, I will be adding content to this page (filling in the table) so that by the time you are presenting, you should have a nice summary of some things to look out for. Once the table is completed, I will prepare a nice PDF of this table for you to download that can be nicely printed out: DOWNLOAD.
