ルールを破る人の心理、まねされやすいのは「守る人」より「破る人」 750人の実験
Breaking Rules Spreads Fast
1Seeing someone break a rule can make people break it too, a new study has found. But seeing someone follow a rule does not help much.
2Scientists at a university in the Netherlands did the study. The team tested 750 people in the United States online. In a game, a shooting star crossed a row of 100 squares. The rule was to choose the square that shone the brightest. But the farther right a square was, the more money it paid.
3At first, players had no information about others. They chose the square on the far right about 23 percent of the time. Then players learned what an earlier player had done. Seeing a big rule breaker made many people break the rule more. Seeing a rule follower changed very little.
4Another expert said real life is different because it has punishments. The study was published on October 21.

全文訳
1だれかがルールを破るのを見ると、自分も破りやすくなることが、新しい研究でわかりました。でも、ルールを守る人を見ても、あまり効果はありません。
2研究したのは、オランダの大学の科学者たちです。チームは、アメリカの750人をネットで調べました。ゲームの中で、流れ星が100個の四角が並んだ列の上を横切りました。ルールは、いちばん明るく光った四角を選ぶことでした。でも、右にある四角ほど、もらえるお金が多くなりました。
3最初、プレーヤーはほかの人のことを何も知りませんでした。そのとき、いちばん右の四角を選んだのは、全体の約23%でした。次に、プレーヤーは前の人が何をしたかを知らされました。大きくルールを破った人を見ると、多くの人がもっとルールを破りました。ルールを守った人を見ても、ほとんど何も変わりませんでした。
4別の専門家は、現実には罰があるので、ゲームとはちがうと言いました。この研究は10月21日に発表されました。
文法ポイント:動名詞の主語(~ing が主語になる)
~ing(動名詞)が「~すること」の意味で文の主語になる。本文の Seeing a big rule breaker made many people break the rule more. は「大きくルールを破る人を見ることが、多くの人にもっとルールを破らせた」。動名詞の主語は3人称単数あつかい。
