I would put it as "people misunderstand the source of their emotional resilience". A lot of people think that having "strong will" or "strong values" is what will prevent them from picking up extreme, obsessive or hateful ideas.

Instead, anything like resilience is a process. Your friends and your community is part of it. Everyone is suggestible, everyone takes beliefs from associates as well as from experience. Conspiratorial and prejudiced ideas are seductive specifically because of how uncertain the world is. One has to reject such ideas in a way that avoids considering them in terms of "either this is true or this is false" since so many questions well beyond proof either way.
