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