I think there are only two exceptions that I'm aware of -- two-year-olds, they are not rational, they have very fickle preferences, they switch what they think all the time, and schizophrenics are probably not rational, but pretty much everybody else is rational.
私が思うに例外は２つだけです ２歳児は合理的ではありません 気まぐれな嗜好を持っており いつも考えをコロコロ変えます そして統合失調症患者は おそらく合理的ではありません しかし その他の人々はみな合理的なのです
