HOLLY H. SCHIFFRIN The last few years, a difficult economic recession has required many Americans to cut back on unnecessary purchases and leisure activities. Despite the feeling of sacrifice, people may be learning important lessons about living in a way that brings greater happiness. The expression money cant buy happiness is an extremely hard maxim for many to accept. So they seem to think that if we could just make more money, then we would be happier. The truth is that people are adaptable and resilient. If there is an annoying light fixture flickering overhead, at first we think it will drive us crazy, but soon we barely notice it. Or we are able to tune out annoying noise (traffic outside our window) and focus on the task at hand. People habituate easily to distracting stimuli in the environment and are able to focus on important things. Indeed, we habituate to most circumstances of our lives, whether good or bad, in a relatively short period and maintain a somewhat consistent level of happiness over time. While its true that people get a surge of happiness when they make a big purchase or experience a change in life circumstances, they soon generally return to their original state of happiness. There are two factors that researchers use to explain this phenomenon. First, there is a strong genetic basis to happiness that determines a persons happiness set point. This genetic set point is like a thermostat. After the temperature in the house rises (or happiness increases), the heat turns off until the house cools down to the temperature set on the thermostat (the happiness set point). In happiness terms, this cooling off process is referred to as hedonic adaptation, the second factor in adapting to life circumstances. People adapt to hedonic pleasures in their lives and return to their baseline level of happiness. This relationship also holds true for society at large, as demonstrated by whats called the progress paradox: Despite significant progress and economic growth over the past 50 years, happiness levels have remained relatively constant or declined. The good news is that the genetic basis of happiness accounts for about only 50 percent of peoples happiness levels. The things that we think would make us happy - such as more money, a bigger house, a newer car, or the latest electronic gadget - really dont contribute that much to happiness. Taken together, the circumstances of life, including wealth, marriage, health, attractiveness and education level, account for only 10 percent of our happiness because we habituate to our circumstances. Big changes quickly become a normal part of life. There are a few qualifications to the general rule that money doesnt buy happiness. Money is related to happiness when people do not have enough money to meet basic needs for food, shelter, and clothing and still have a little left over for nonessentials. But a new study by Nobel Prize winner Daniel Kahneman at Princeton University identified $75,000 (depending upon where you live) as the income above which the relationship between happiness and income basically disappears. More income does not translate to being happier. So, if about 50 percent of happiness is explained by our genes and 10 percent by our life circumstances, what accounts for the remaining 40 percent? Researchers are starting to view happiness as similar to weight loss. There is a genetic basis for the weight that each persons body will tend to maintain (again, a set point), which is often higher than wed like. In order to lose weight, we must make lifestyle changes to diet and activity levels. Analogously, this same type of intentional activity can increase happiness above the natural set point. The activities that promote happiness are those we have resorted to during the recession because we havent had as much disposable income as usual, such as staying at home for game or movie nights with family and friends. The No. 1 predictor of happiness across studies and cultures is good relationships. Spending time with the people we care about increases positive feelings as well as building social support that we can call on in times of. There is evidence that spending money on experiences can increase happiness. Having a picnic or taking a vacation allows us to increase happiness through several mechanisms. Savouring the experience in the moment and reminiscing about it afterward are both associated with increased happiness. And finally, being grateful for what we have, even during difficult economic times, increases happiness. So the question is, will we go back to our old spending habits after economic recovery? Or will we take to heart the lessons weve learned during this recession, making permanent changes in how we spend our time and money that may ultimately increase happiness? - St. Petersburg Times
