Arthur C. Brooks: Choose to Be Grateful. It Will Make You Happier [OPINION]

For many people, gratitude is difficult, because life is difficult. Even beyond deprivation and depression, there are many ordinary circumstances in which gratitude doesn’t come easily.

Beyond rotten circumstances, some people are just naturally more grateful than others. A 2014 article in the journal Social Cognitive and Affective Neuroscience identified a variation in a gene (CD38) associated with gratitude. Some people simply have a heightened genetic tendency to experience, in the researchers’ words, “global relationship satisfaction, perceived partner responsiveness and positive emotions (particularly love).” That is, those relentlessly positive people you know who seem grateful all the time may simply be mutants.

But we are more than slaves to our feelings, circumstances and genes. Evidence suggests that we can actively choose to practice gratitude — and that doing so raises our happiness.

How does all this work? One explanation is that acting happy, regardless of feelings, coaxes one’s brain into processing positive emotions. In one famous 1993 experiment, researchers asked human subjects to smile forcibly for 20 seconds while tensing facial muscles, notably the muscles around the eyes called the orbicularis oculi (which create “crow’s feet”). They found that this action stimulated brain activity associated with positive emotions.

If grinning for an uncomfortably long time like a scary lunatic isn’t your cup of tea, try expressing gratitude instead. According to research published in the journal Cerebral Cortex, gratitude stimulates the hypothalamus (a key part of the brain that regulates stress) and the ventral tegmental area (part of our “reward circuitry” that produces the sensation of pleasure).

It’s science, but also common sense: Choosing to focus on good things makes you feel better than focusing on bad things. As my teenage kids would say, “Thank you, Captain Obvious.” In the slightly more elegant language of the Stoic philosopher Epictetus, “He is a man of sense who does not grieve for what he has not, but rejoices in what he has.”

In addition to building our own happiness, choosing gratitude can also bring out the best in those around us. Researchers at the University of Southern California showed this in a 2011 study of people with high power but low emotional security (think of the worst boss you’ve ever had). The research demonstrated that when their competence was questioned, the subjects tended to lash out with aggression and personal denigration. When shown gratitude, however, they reduced the bad behavior. That is, the best way to disarm an angry interlocutor is with a warm “thank you.”

Finally, be grateful for "useless things". It is relatively easy to be thankful for the most important and obvious parts of life — a happy marriage, healthy kids or living wealthy. But truly happy people find ways to give thanks for the little, insignificant trifles.

This Festive season, don’t express gratitude only when you feel it. Give thanks especially when you don’t feel it. Rebel against the emotional “authenticity” that holds you back from your bliss. As for me, I am taking my own advice and updating my gratitude list. It includes my family, faith, friends and work. And it includes you, for reading this column.
