Researcher Ed Diener
In a new study, researchers at the University of Illinois put Maslow’s ideas to the test with data from 123 countries representing every major region of the world.
“Anyone who has ever completed a psychology class has heard of Abraham Maslow and his theory of needs,” said University of Illinois professor emeritus of psychology Ed Diener, who led the study. “But the nagging question has always been: Where is the proof? Students learn the theory, but scientific research backing this theory is rarely mentioned.”
The researchers turned to the Gallup World Poll, which conducted surveys in 155 countries from 2005 to 2010, and included questions about money, food, shelter, safety, social support, feeling respected, being self-directed, having a sense of mastery, and the experience of positive or negative emotions. Diener, a senior scientist for the Gallup Organization, helped design the survey.

They also found that the fulfillment of more basic needs – for money, food or shelter, for example – was more closely linked to a positive life evaluation, the way an individual ranked his or her life on a scale from worst to best. The satisfaction of higher needs – for social support, respect, autonomy or mastery – was “more strongly related to enjoying life – having more positive feelings and less negative feelings,” Diener said.
An important finding, Diener said, is that the research indicated that people have higher life evaluations when others in society also have their needs fulfilled.
“Thus life satisfaction is not just an individual affair, but depends substantially also on the quality of life of one’s fellow citizens,” he said.
“Our findings suggest that Maslow’s theory is largely correct. In cultures all over the world the fulfillment of his proposed needs correlates with happiness,” Diener said. “However, an important departure from Maslow’s theory is that we found that a person can report having good social relationships and self-actualization even if their basic needs and safety needs are not completely fulfilled.”
“Another revision of his theory is that we found that different needs produce different types of well-being,” Diener said.
