While both economic and social considerations of fairness and equity play an important role in financial decision-making, it is not clear which of these two motives is more primal and immediate and which one is secondary and slow. Here we used variants of the ultimatum game to examine this question. Experiment 1 shows that acceptance rate of unfair offers increases when participants are asked to base their choice on their gut-feelings, as compared to when they thoroughly consider the available information. (...) In line with these results, Experiments 2 and 3 provide process evidence that individuals prefer to first examine economic information about their own utility rather than social information about equity and fairness, even at the price of foregoing such social information. Our results suggest that people are more economically rational at the core, but social considerations (e.g., inequality aversion) require deliberation, which under certain conditions override their self-interested impulses.

Three-time New York Times bestselling author Dan Ariely teams up with legendary The New Yorker cartoonist William Haefeli to present an expanded, illustrated collection of his immensely popularWall Street Journal advice column, “Ask Ariely”. Behavioral economist Dan Ariely revolutionized the way we think about ourselves, our minds, and our actions in his books Predictably Irrational, The Upside of Irrationality, and The Honest Truth about Dishonesty. Ariely applies this scientific analysis of the human condition in his “Ask Ariely” Q & A (...) column in the Wall Street Journal, in which he responds to readers who write in with personal conundrums ranging from the serious to the curious: What can you do to stay calm when you’re playing the volatile stock market? What’s the best way to get someone to stop smoking? How can you maximize the return on your investment at an all-you-can-eat buffet? Is it possible to put a price on the human soul? Can you ever rationally justify spending thousands of dollars on a Rolex? In Ask Ariely, a broad variety of economic, ethical, and emotional dilemmas are explored and addressed through text and images. Using their trademark insight and wit, Ariely and Haefeli help us reflect on how we can reason our way through external and internal challenges. Readers will laugh, learn, and most importantly gain a new perspective on how to deal with the inevitable problems that plague our daily life. (shrink)
