Most people's faces match their personality. This has nothing to do with halo effect. I can't believe people are denying this. Incels that have high trust faces usually are nice people to be around. They tend not to anger easily.
A guy like Elliott Rodger is not high trust and has a psychotic look about his face even if you never watched one of his videos.
Low trust slayers are always aggressive douchebags.
High trust slayers are friendly.
You will NEVER encounter a guy with a low trust robust slayer face who prances around like a submissive fairy.
