Our social world is ruled by the affect heuristic: what feels good seems true, and what feels bad we distance ourselves from and reject. We judge what’s true or false based on it if makes us feel good or bad.
I think I’m going to stop talking to people socially about nuclear weapons and climate change.
Almost always, what the other person really wants is reassurance that their future will be OK and that the choices they are making are OK.
The conversation tends to become a cross-examination where they look for a way to dismiss me in order to protect their hopefulness and view of themself as a good person. It’s a bit like how people feel compelled to tell me how particularly important or moral (or not enjoyed) their air travel plans are, as though I am a religious authority who can forgive them. “Confess and be forgiven” is a cheerful motto for those who refuse to change their behaviour.
These conversations tend to be miserable for both sides: for them because they are presented with evidence for why they really should be fearful, when they fervently want the opposite, and for me because it just leads to more alienation to see how utterly unwilling people are to even face the problem, much less take any commensurate action. If I am convincing and give good evidence, it makes things worse for both: for them because they are getting anxious instead of reassured and for me because it reinforces how little relationship there is between evidence and human decision-making.
It is also a fundamental error to think that if a person believes that a problem is serious and that you are working on it, they will support you. You might think the chain of logic would be “the person seems to be working on a problem which I consider real and important, so I will support them at least conversationally if not materially” when it is much more often “this person is talking about something that makes me feel bad, so I will find a way to believe that they are wrong or what they are saying is irrelevant”. The desire to feel good about ourselves and the world quickly and reliably trumps whatever desire we may have to believe true things or act in a manner consistent with out beliefs.
It seems smarter going forward just to say that I won’t discuss these subjects and whatever work I am doing on them is secret.
It’s crucial when setting such boundaries to refuse to debate or justify them. Let people through that crack, and it’s sure to become another affect-driven argument about how they prefer to imagine their future as stable, safe, and prosperous and their own conduct as wise and moral — with me cast as the meanie squashing their joys.
