On average kind people are just being kind.
And that is great, it is good to be optimistic. My point is being kind has nothing to do with trustworthiness. Hell, someone that is kind can also just be plain wrong. They might think they know something when they do not. The kindness just does not factor in to knowledge. Plenty of experts are not what people would describe as kind, and plenty of misinformation peddlers are kind. It just has nothing to do with expertise
