When your partner does something that bothers you, don’t go with your gut reaction. Think before you blame, and be especially wary of what psychologists call the “fundamental attribution error.” When we do something wrong ourselves, we often blame it on temporary external circumstances: Yes, I lost my temper a couple of times today, but that’s just because of all the stress from the quarantine. But when our partner does something wrong, we’re inclined to wrongly attribute it to permanent internal flaws: He lost his temper because he has lousy self-control and doesn’t care about how I feel.
