Spent Review: Why Consumers Empty their Pockets
Society revolves around an endless parade of enviable goods—Rolex watches, Prada handbags, cars flaunting the Ferrari logo, and artwork by Rembrandt, Monet, or Warhol. After depositing a paycheck, we race to the shopping mall to snatch up the latest and greatest items, never pausing to consider the true reasons behind our “need” for these products. So why do we buy? Geoffrey Miller, an evolutionary psychologist from the University of New Mexico, dives headfirst into this question in his new book Spent: Sex, Evolution, and Consumer Behavior. He provides a comprehensive account of how our purchases function primarily as signals that advertise our underlying personality traits, and only secondarily as objects with material value.
