The section on measuring over-confidence is interesting, specifically how they address the shortcoming of self-reporting confidence (if you're bad at the task in the first place, you're also going to be bad at estimating your performance, where the act of estimating resembles the task itself).
Another fun activity is to visit the appendix (p. 47) which lists all of the True and False Conspiracies used in their assessment.
