I don't even mean negative reinforcement in an abusive way, although it often is. People just tend to remember when others were angry at them a lot more than when others were encouraging
I guess my observation is that people tend to internalize negative interactions much more freely than they internalize positive interactions. Therefore if there is a lesson alongside the negative interaction, they remember that lesson
I also think people tend to question positive interactions a lot more than they question negative interactions. Maybe I just interact with a lot of people with low self esteem though
I'm not saying that negative reinforcement is good or the right way we should do things. Just observing that it seems more effective at reaching people
