How Negativity Can Kill a Relationship

John Tierney & Roy Baumeister:

There’s an elegant symmetry to traditional wedding vows: for better or for worse. But love is not symmetrical, and most of us don’t realize how lopsided it can be. The worse matters far more than the better in marriage or any other relationship. That’s how the brain works.

Our thoughts and feelings are skewed by what researchers call the negativity effect, which is our tendency to respond more strongly to negative events and emotions than to positive ones. When we hear a mix of compliments and criticism, we obsess over the criticism instead of enjoying the praise. This imbalance, also known as the negativity bias, evolved in the brain because it kept our ancestors alert to deadly threats, but too often it warps our perspective and behavior. A slight conflict can have ruinous consequences when the power of bad overwhelms your judgment, provoking you to actions that further alienate your partner. You’d fare better by using your rational brain to override your irrational impulses, but to do that you need first to understand just how powerful bad can be.

In relationships, the negativity effect magnifies your partner’s faults, real or imagined, starting with their ingratitude, because you’re also biased by an internal overconfidence that magnifies your own strengths. So you wonder how your partner can be so selfish and so blind to your virtues—to all that you’ve done for them. You contemplate one of life’s most exasperating mysteries: Why don’t they appreciate me?
