I think this is the notion of "dark arts" in HPMOR. You don't necessarily become "one of those people" when you learn the tricks. You can choose not to employ them. But I feel like not everyone I meet will be cooperative and that's why it's handy to keep the "dark arts" in my back pocket when I encounter non-cooperative people.
