I attended a talk yesterday given under the auspices of the Ottawa Skeptics on the subject of "metacognition" or thinking about thinking -- basically, it was about core rationality concepts. It was designed to appeal to a broad group of lay people interested in science and consisted of a number of examples drawn from pop-sci books such as Thinking, Fast and Slow and Predictably Irrational. (Also mentioned: straw vulcans as described by CFAR's own Julia Galef.) If people who aren't familiar with LW ask you what LW is about, I'd strongly recommend pointing them to this video.

Here's the link.
