That’s a difference of about three and a half days without expressions of gratitude in some couples.Īnother gene that appears to influence gratitude is a gene called “COMT,” which is involved in the recycling of the neurotransmitter dopamine in the brain. Partners with one particular variant of the CD38 gene reported thanking their partners about 45 percent of the days, whereas partners with another variant thanked their partners more than 70 percent of the days. In one part of this study, for example, members of heterosexual romantic couples noted whether “I thanked my partner for something they did that I appreciated” every night for two weeks. A study by Sara Algoe and colleagues found that differences in this gene were significantly associated with the quality and frequency of expressions of gratitude toward a romantic partner in both the lab and in regular daily life. One promising candidate is a gene, CD38, involved in the secretion of the neuropeptide oxytocin. Other studies have explored what specific genes may underlie a person’s grateful (or less grateful) disposition. In this study by Michael Steger and colleagues, identical twins-who essentially have the same DNA-had more similar self-reported levels of gratitude than did fraternal twins-who share only 50 percent of their DNA-suggesting that there may be a genetic component to gratitude. Perhaps the strongest evidence supporting this genetic basis for gratitude comes from a study of twins. Genetics may help explain why some people find it easier to feel and express gratitude than others. But if you’re having trouble feeling grateful, don’t despair! Gratitude isn’t purely hard-wired, and-as we’ll explore below-there are things you can do to bring more gratitude into your life. Research suggests that these differences may be rooted in our brains, genes, and even our personalities. For some of us, gratitude just doesn’t come as easy. But the truth is that some people have more grateful dispositions than others. Gratitude is good for your psychological well-being, your relationships, and possibly even your physical health. There are many benefits to being grateful.
