>But the actual problem can't be solved on Twitter or Mastodon. Each individual needs to be aware of this human problem and to constantly make an effort to notice and counteract it in their own brain (which is very difficult and error prone). Perhaps if enough people start doing that more, then cultural change will take place. I don't know.

Twitter has a profit incentive against people solving this problem. Places like Mastodon at least have the possibility of designing against the issue or somehow encouraging education about it.
