Why do so many of us remember—in detail—all the negative things our spouse did or said, from the beginning of the relationship until today? "You're always late." "This place is a mess." "You never listen to me."
Why can't a big bouquet of roses or a coveted ticket to a favorite sporting event make up for several things that caused hurt feelings? Why do we remember critical remarks more than positive ones? You can blame it on the brain.
Studies conducted by Dr. John Cacioppo of the University of Chicago have shown what he calls "the negativity bias" of the brain. Our brains are actually more sensitive and responsive to unpleasant news. That's why personal insults or criticism hit us harder and stay with us longer. It's why negative ads are more effective than positive ones—political or otherwise.
It's a numbers game
Not only do we have a built-in partiality toward negative information, but negatives increase disproportionately over positives. It's not a one-to-one ratio. In other words, one positive cannot offset one negative. When you tell your husband, "Thanks for giving the kids a bath, honey," and five minutes later say, "You forgot to take out the trash—again," the negative drowns out the positive.
Our brain needs a higher number of positive entries to counterbalance this built-in negativity bias. And several small, frequent, positive acts pack more punch than one giant-size positive. The size of the positive doesn't count; quantity does. It's strictly a numbers game.
