When Is a Poker Face Not a Poker Face?

A new study finds that a resolutely neutral facial expression may not be the best strategy when playing poker. “Surprisingly, we find that threatening face information has little influence on wagering behavior, but faces relaying positive emotional characteristics impact peoples’ decisions,” write?Erik J. Schlicht, Shinsuke Shimojo, Colin F. Camerer, Peter Battaglia, and Ken Nakayama. Opponents of “emotionally positive” players mistakenly folded more often. The authors conclude that “the best ‘poker face’ for bluffing may not be a neutral face, but rather a face that contains emotional correlates of trustworthiness.” (HT: Joel Schnur) [%comments]
