The supermarket is designed to lure customers into spending as much time as possible within its doors.【这家超市旨在吸引消费者在它的店里尽可能多的时间。】The reason for this is simple: The longer

you stay in the store, the more stuff you’ll see, and the more stuff you see, the more you’ll buy.【理由很简单：你在店里的时间越长，你将会看到更多的东西，而你看到更多的东西，你将会买的更多。】

And supermarkets contain a lot of stuff.【超市里有大量的商品。】The average supermarket, according to the Food Marketing Institute, carries some 44,000 different items, and many carry tens of thousands more.【根据食品市场研究所的报告，超市平均拥有44，000不同商品，很多还会多出数万种商品。】The sheer volume of available choice is enough to send shoppers into a state of information overload.【非常多可供选择的数量足以让消费者进入信息过载的状态。】

According to brain-scan experiments, the demands of so much decision-making quickly become too much for us.【根据大脑扫描实验，快速做出如此多决策的要求对我们来说太过了。】After about 40minutes of shopping, most people stop struggling to be rationally selective, and instead begin shopping emotionally—which is the point at which we accumulate the 50 percent of stuff in our cart that we never intended buying.【在大约购物40分钟以后，大多数人不再努力去理性购物，取而代之是情绪化购物——就是这一点让我的购物车中多出50%的东西是我们从来没有想过购买的。】
