And the problem is that — although in the case of sending people to prison, you have this impartial judiciary determining who gets excluded from the golden rule — that in everyday life, the way we all make these decisions about who we're not going to extend the golden rule to, is we use a much rougher and readier formula. Basically it's just like, if you're my enemy, if you're my rival — if you're not my friend, if you're not in my family — I'm much less inclined to apply the golden rule to you.
Y el problema es que, aunque en el caso de enviar personas a prisión contamos con un poder judicial imparcial que determina a quién se excluye de la regla de oro, en la vida cotidiana tomamos las decisiones acerca de a quiénes no vamos a tratar con la regla de oro con una fórmula más expedita y menos precisa, que básicamente se reduce a si eres mi enemigo, si eres mi rival, si no eres mi amigo, si no formas parte de mi familia estaré mucho menos inclinado a aplicarte la regla de oro. Ok.
