宝くじにあたってもずっと幸せにはなれない。

宝くじにあたってもずっと幸せにはなれない。

TEDのダン・ギルバード教授「私たちが幸せを感じる理由」を見たのですが、その中で次のようなことを知りました。

宝くじに当たった人と事故で体が麻痺している人の幸福度を調べた調査があります。
普通で考えると宝くじにあたった人の方が体が不自由な人より幸せになるように思います。
しかし、くじに当たって一年後、事故で体が不自由になってから一年経った人たちを比べると幸せ度は2つのグループで変わらなかったそうです。

一時的な喜びや苦しみは日々の生活の中で薄れていき、毎日の生活で幸せを見つけることが大切だというお話でした。

Abstract
Adaptation level theory suggests that both contrast and habituation will operate to prevent the winning of a fortune from elevating happiness as much as might be expected. Contrast with the peak experience of winning should lessen the impact of ordinary pleasures, while habituation should eventually reduce the value of new pleasures made possible by winning. Study 1 compared a sample of 22 major lottery winners with 22 controls and also with a group of 29 paralyzed accident victims who had been previously interviewed. As predicted, lottery winners were not happier than controls and took significantly less pleasure from a series of mundane events. Study 2, using 86 Ss who lived close to past lottery winners, indicated that these effects were not due to preexisting differences between people who buy or do not buy lottery tickets or between interviews that made or did not make the lottery salient. Paraplegics also demonstrated a contrast effect, not by enhancing minor pleasures but by idealizing their past, which did not help their present happiness.
