"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 a study to be published in the Journal of Positive Psychology, 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 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.
The study participants reported deriving meaning from giving a part of themselves away to others and making a sacrifice on behalf of the overall group. In the words of Martin E. P. Seligman, one of the leading psychological scientists alive today, in the meaningful life "you use your highest strengths and talents to belong to and serve something you believe is larger than the self."
For instance, having more meaning in one's life was associated with activities like buying presents for others, taking care of kids, and arguing. People whose lives have high levels of meaning often actively seek meaning out even when they know it will come at the expense of happiness. Because they have invested themselves in something bigger than themselves, they also worry more and have higher levels of stress and anxiety in their lives than happy people. Having children, for example, is associated with the meaningful life and requires self-sacrifice, but it has been famously associated with low happiness among parents, including the ones in this study.
