サイエンス誌から。貧乏な人が「さらに貧乏になるような振る舞い(過度の借金など)」をしてしまうのは、目の前の問題に集中し過ぎてしまうから。「金銭的な貧乏」に限らず、「時間的な貧乏」にも同じ事が言える。 http://www.sciencemag.org/content/338/6107/682

Poor individuals often engage in behaviors, such as excessive borrowing, that reinforce the conditions of poverty. Some explanations for these behaviors focus on personality traits of the poor. Others emphasize environmental factors such as housing or financial access. We instead consider how certain behaviors stem simply from having less. We suggest that scarcity changes how people allocate attention: It leads them to engage more deeply in some problems while neglecting others. Across several experiments, we show that scarcity leads to attentional shifts that can help to explain behaviors such as overborrowing. We discuss how this mechanism might also explain other puzzles of poverty.
