I heard Jonathan Haidt on Start the Week and liked what he had to say.
Here are the three points:
The Untruth of Fragility: What doesn’t kill you makes you weaker.
The Untruth of Emotional Reasoning: Always trust your feelings.
The Untruth of Us vs. Them: Life is a battle between good people and evil people.
I tend to feel the first two while teaching university. The second is something I’ve spent my entire high-school teaching career railing against; kids and peers are undoubtedly sick of me saying “emotions aren’t evidence” alongside of “what’s your evidence for that claim.”
