I actually hold the opposite opinion; that most people are generally good, or at the least, focused on their own problems most of the time.

This isn't just personal experience (I'm old so have a bunch) but one example is that I watch a lot of travelling vlogs, mostly motorbikes. Whenever a rider has a breakdown, even in the middle of nowhere, someone will be along and will help. Even allowing for a general positive bias of the media, those who would take advantage of that situation are a tiny percentage.

What does happen though, is that those who aren't good can abuse the goodness of others to gain power and influence, so are statistically more noticable.
