Is it possible for people in online communication to have something like an intellectual credit score? The idea is that you run a risk when interacting with someone just as you run a risk when lending money to someone. You are lending them your time and credence and to a certain degree your reputation. There could be a way of quantifying whether people have repaid that risk with others in the past or whether they have ripped people off, and whether in general they act in a responsible intellectual fashion. For example if they make it clear what would count as proof or disproof of a position and then change it accordingly when given evidence, that would give a person a good intellectual credit rating. If they put forward a position and then later lie and claim they never said any such thing, they would get a bad intellectual credit rating. And so on.
My hope would be that this would not perpetuate an echo chamber — i.e. you can be a responsible liberal or a responsible conservative, and an irresponsible liberal or irresponsible conservative. But it would allow us not to lend our time and attention and emotions to people who are bad actors.
Of course there are probably intellectual positions that are only held by people with pretty poor intellectual credit ratings. But that is to be expected. In a multi-level marketing scheme or a a factory that makes perpetual motion machines or some other scam, the only investors will be people whose credit ratings (financial I mean) tend to be poor — because they have bad judgment, and because their bad credit means they have fewer opportunities to invest. So in the epistemic case. People are attracted to fringe positions like flat earthing, anti-vaxing, and right-wing nationalism because they have poor judgment, and because their poor judgment means they have been shunned from or have deliberately avoided more responsible intellectual communities.
Needless to say if you want to engage in an argument with somebody with a poor intellectual credit rating you might learn something new — you will certainly be exposed to ideas that you won’t be if you hang with more responsible citizens.
But beware — you may also waste your time.
