"Watch out for gorillas!"  "Don't trade with strangers."  "Buy this now!"  Our brains are constantly bombarded with messages about how to behave, what to buy, and whom to trust.  How do we parse these messages, and how do our choices affect the world economy?   This week on Skepticality, Derek & Swoopy discuss how economic and evolutionary theory speak the same language, and how our hardwired human biology affects modern economics, with Skeptic Society founder Dr. Michael Shermer author of The Mind of the Market: Compassionate Apes, Competitive Humans and Other Tales from Evolutionary Economics.

Skepticality welcomes 2008 with an update from the Secular Coalition for America's Lori Lipman Brown — the only lobbyist dedicated solely to the concerns of secular humanists and non-theists and to the preservation of the separation of church and state. Lori talks with Derek and Swoopy about why 2007 was the best year yet for the SCA, the top issues on the agenda for 2008, and how the current presidential candidates stack up on the issues important to skeptics.
