It's also a heritable trait, at least based on the slew of research I found when googling impulse control genes.

That doesn't mean it can't be improved, but it does mean we should be respectful of people who may have a much harder time with it. Not everyone can meet a societal baseline that's challenging enough for people deemed to be normative; a person with one arm is plenty likely to be good at basketball, but imposing qualification rules based on their capability to do free throws might be a bit out of bounds... so to speak.

That's what algorithm (self-)regulations (and gripes along what Mozilla published here) would aim to address.
