This is why some researchers are cautioning against the pursuit of mere happiness. In a new study, which will be published this year in a forthcoming issue of the Journal of Positive Psychology, psychological scientists asked nearly 400 Americans aged 18 to 78 whether they thought their lives were meaningful and/or happy. 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."
"Happiness without meaning characterizes a relatively shallow, self-absorbed or even selfish life, in which things go well, needs and desire are easily satisfied, and difficult or taxing entanglements are avoided," the authors write.
How do the happy life and the meaningful life differ? Happiness, they found, is about feeling good. Specifically, the researchers found that people who are happy tend to think that life is easy, they are in good physical health, and they are able to buy the things that they need and want. While not having enough money decreases how happy and meaningful you consider your life to be, it has a much greater impact on happiness. The happy life is also defined by a lack of stress or worry.
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.
"Happy people get a lot of joy from receiving benefits from others while people leading meaningful lives get a lot of joy from giving to others," explained Kathleen Vohs, one of the authors of the study, in a recent presentation at the University of Pennsylvania. In other words, meaning transcends the self while happiness is all about giving the self what it wants. People who have high meaning in their lives are more likely to help others in need. "If anything, pure happiness is linked to not helping others in need," the researchers, which include Stanford University's Jennifer Aaker and Emily Garbinsky, write.
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.
