AGE AND HAPPINESS

Age and happiness

Dec 16th 2010 | from PRINT EDITION

ASK people how they feel about getting older, and they will probably reply in the same vein as Maurice Chevalier: “Old age isn’t so bad when you consider the alternative.” Stiffening joints, weakening muscles, fading eyesight and the clouding of memory, coupled with the modern world’s careless contempt for the old, seem a fearful prospect—better than death, perhaps, but not much. Yet mankind is wrong to dread ageing. Life is not a long slow decline from sunlit uplands towards the valley of death. It is, rather, a U-bend.

When people start out on adult life, they are, on average, pretty cheerful. Things go downhill from youth to middle age until they reach a nadir commonly known as the mid-life crisis. So far, so familiar. The surprising part happens after that. Although as people move towards old age they lose things they treasure—vitality, mental sharpness and looks—they also gain what people spend their lives pursuing: happiness.

This curious finding has emerged from a new branch of economics that seeks a more satisfactory measure than money of human well-being. Conventional economics uses money as a proxy for utility—the dismal way in which the discipline talks about happiness. But some economists, unconvinced that there is a direct relationship between money and well-being, have decided to go to the nub of the matter and measure happiness itself.

These ideas have penetrated the policy arena, starting in Bhutan, where the concept of Gross National Happiness shapes the planning process. All new policies have to have a GNH assessment, similar to the environmental-impact assessment common in other countries. In 2008 France’s president, Nicolas Sarkozy, asked two Nobel-prize-winning economists, Amartya Sen and Joseph Stiglitz, to come up with a broader measure of national contentedness than GDP. Then last month, in a touchy-feely gesture not typical of Britain, David Cameron announced that the British government would start collecting figures on well-being.

There are already a lot of data on the subject collected by, for instance, America’s General Social Survey, Eurobarometer and Gallup. Surveys ask two main sorts of question. One concerns people’s assessment of their lives, and the other how they feel at any particular time. The first goes along the lines of: thinking about your life as a whole, how do you feel? The second is something like: yesterday, did you feel happy/contented/angry/anxious? The first sort of question is said to measure global well-being, and the second hedonic or emotional well-being. They do not always elicit the same response: having children, for instance, tends to make people feel better about their life as a whole, but also increases the chance that they felt angry or anxious yesterday.

Statisticians trawl through the vast quantities of data these surveys produce rather as miners panning for gold. They are trying to find the answer to the perennial question: what makes people happy?

Four main factors, it seems: gender, personality, external circumstances and age. Women, by and large, are slightly happier than men. But they are also more susceptible to depression: a fifth to a quarter of women experience depression at some point in their lives, compared with around a tenth of men. Which suggests either that women are more likely to experience more extreme emotions, or that a few women are more miserable than men, while most are more cheerful.

Two personality traits shine through the complexity of economists’ regression analyses: neuroticism and extroversion. Neurotic people—those who are prone to guilt, anger and anxiety—tend to be unhappy. This is more than a tautological observation about people’s mood when asked about their feelings by pollsters or economists. Studies following people over many years have shown that neuroticism is a stable personality trait and a good predictor of levels of happiness. Neurotic people are not just prone to negative feelings: they also tend to have low emotional intelligence, which makes them bad at forming or managing relationships, and that in turn makes them unhappy.

Whereas neuroticism tends to make for gloomy types, extroversion does the opposite. Those who like working in teams and who relish parties tend to be happier than those who shut their office doors in the daytime and hole up at home in the evenings. This personality trait may help explain some cross-cultural differences: a study comparing similar groups of British, Chinese and Japanese people found that the British were, on average, both more extrovert and happier than the Chinese and Japanese.

Then there is the role of circumstance. All sorts of things in people’s lives, such as relationships, education, income and health, shape the way they feel. Being married gives people a considerable uplift, but not as big as the gloom that springs from being unemployed. In America, being black used to be associated with lower levels of happiness—though the most recent figures suggest that being black or Hispanic is nowadays associated with greater happiness. People with children in the house are less happy than those without. More educated people are happier, but that effect disappears once income is controlled for. Education, in other words, seems to make people happy because it makes them richer. And richer people are happier than poor ones—though just how much is a source of argument.

The ageing of the rich world is normally seen as a burden on the economy and a problem to be solved. The U-bend argues for a more positive view of the matter. The greyer the world gets, the brighter it becomes—a prospect which should be especially encouraging to Economist readers (average age 47).
