Examining their self-reported attitudes toward meaning, happiness, and many other variables — like stress levels, spending patterns, and having children — over a month-long period, the researchers found that a meaningful life and happy life overlap in certain ways, but are ultimately very different. Leading a happy life, the psychologists found, is associated with being a “taker” while leading a meaningful life corresponds with being a “giver.”
Most importantly from a social perspective, the pursuit of happiness is associated with selfish behavior — being, as mentioned, a “taker” rather than a “giver.” The psychologists give an evolutionary explanation for this: happiness is about drive reduction. If you have a need or a desire — like hunger — you satisfy it, and that makes you happy. People become happy, in other words, when they get what they want. Humans, then, are not the only ones who can feel happy. Animals have needs and drives, too, and when those drives are satisfied, animals also feel happy, the researchers point out.
What sets human beings apart from animals is not the pursuit of happiness, which occurs all across the natural world, but the pursuit of meaning, which is unique to humans, according to Roy Baumeister, the lead researcher of the study and author, with John Tierney, of the recent book Willpower: Rediscovering the Greatest Human Strength. Baumeister, a social psychologists at Florida State University, was named an ISI highly cited scientific researcher in 2003.
Meaning is not only about transcending the self, but also about transcending the present moment — which is perhaps the most important finding of the study, according to the researchers. While happiness is an emotion felt in the here and now, it ultimately fades away, just as all emotions do; positive affect and feelings of pleasure are fleeting. The amount of time people report feeling good or bad correlates with happiness but not at all with meaning. Meaning, on the other hand, is enduring. It connects the past to the present to the future. “Thinking beyond the present moment, into the past or future, was a sign of the relatively meaningful but unhappy life,” the researchers write. “Happiness is not generally found in contemplating the past or future.” That is, people who thought more about the present were happier, but people who spent more time thinking about the future or about past struggles and sufferings felt more meaning in their lives, though they were less happy.
