Or rather, to stop pretending we can put ourselves in other's shoes.
Talking to eg. abortion opponents, I usually get the impression that they have done a few thought experiments. They, if you'll allow the straw man, assume/imagine that faced with the same tough decision they would never themselves decide to eg. have an abortion. They're appalled that others (in practice) would choose to do what they (in principle) decide against or vice versa.
As you say, these principles are poor predictors of what people will choose to do in personal, life-or-death reality. Things like the fundamental attribution error make policies based on what-I-would-do-in-a-hypothetical-situation just as impractical as static, by-the-book morality. Perhaps there's a third option.
