Adults who won’t eat pink-hearted steaks might lean on any number of reasons for their position, but almost always it comes down to an aversion to risk, which is at its core an unwillingness to trust the validity and goodwill of any experiences beyond the limited sphere of one’s own. It is — and we’re talking about steak here, so don’t get huffy — a confession of a certain timidity, a defensiveness, an insecurity. It’s not just a fear of change, it’s also a bone-deep fear that the way you’ve always done something — the way that, without outside intervention, you might continue always do it — will turn out not to have been the best way for you after all. The risk of that private humiliation can easily outweigh any benefit that could come from your new, better way. It means that when presented with a risk, you make the choice not to trust.
