Stricter requirements for Mentors.

[Deceptus]

Still waiting on these fabled "good mentors" that get brought up whenever the topic of fixing the mentor system or holding mentors to even a tiny amount of accountability for their actions and the actions of the people wearing the crown all the time.
"There's plenty of good mentors, they just don't wear the crown or speak up, or go into NN" is such a cop out. Those are the places people interact with mentors. If they're not there, then they're not doing the job of a mentor.

It's called negativity bias.

You're more likely to remember negative experiences, even if they're the minority of occurrences, because you associate emotion (negative feelings) with them vs the neutral or positive ones.

Same reason people complain on forums instead of posting positive threads. If you have a good experience, you're more likely to just accept it and move on.
