On August 31, 2010, a scientific paper with the pocket-sized title “Long-running German panel survey shows that personal and economic choices, not just genes, matter for happiness” was published in PNAS (Proceedings of the National Academy of Sciences of the United States of America). The paper sums up a 25-year long empirical study about happiness, and is – according to the authors of the paper – a direct test of set-point theory. Set-point theory holds that long-term adult happiness is stable, and depends mainly on genetic factors and personality traits molded in early life. Set-point theory has been widely accepted, but the verdict of the German study is clear: set-point theory is flawed. Luckily, one might add.
If set-point theory was sound, our level of happiness through life – or lack thereof – would be a consequence of our parents (their genes and their parenting), rather than our own choices. And that would be no fun, would it? So despite claims like “trying to be happier may be as futile as trying to be taller” (Lykken and Tellegen, 1996), it now seems as if we stand a chance of escaping our genes – and our parents, if needed.
To some extend this is nothing new, previously the branch of psychology called positive psychology has shown a correlation between character strength, religion, volunteering and acts of kindness with happiness. However, all previous studies have dealt with the short-term impact. The German study is looking at the long-term effects of personal (as well as economic) choices. Great! So, now the question is: what can we do?
Neuroticism – no, thank you
First, stop being neurotic. Neuroticism affects, not surprisingly, your life satisfaction in a downward direction. Quite a bit (-21 percent) actually. But neuroticism isn’t a choice, is it? Well, according to the German study adult personality is stable, but I think our personality is plastic, although barely so. It seems like we can overcome – or reduce – our neurotic traits, if we make a decision about it, and work on it. Anyway, even if we can’t, we can surely make a choice about which partner we choose. And choosing a neurotic partner will also affect our life satisfaction, by no less than 9 percent. So make sure your to-be partner takes a personality test (like the NEO-AC) before you find yourself in times of trouble, oh, Mother Mary.
Do not focus on your career and your material success
The paper also looked at how people prioritize in life, and how this relates to their life satisfaction. And it turns out that people who prioritize non-zero sum altruistic goals or family goals are better of than those who prioritize their careers and material success the most. Persistently prioritizing altruistic goals adds 36 percent to the life satisfaction, family priorities adds 26 percent. But prioritizing success and material goals subtracts – yes, subtracts – 21 percent. And still a lot of people are extremely focused on career and material wealth. When it comes to family, women are highly affected by how much their partners focus on this. Women gains 24 percent in life satisfaction if their partners highly prioritize family.
It’s also worth noting that the religious people in the study tend to give a higher priority to altruistic and family goals, and lower priority to success goals, than the nonbelievers. And religious people also seems be spend more time on volunteer activities. So, from a life satisfaction perspective, religious people might have an edge. However, their advantage might have little to do with their religious faith, and more to do with the altruistic and family values often associated with religious groups. In other words: the same life satisfaction might be attained by nonbelievers – if they adopt the value system, without the dogma.
Don’t work too much, don’t work too little
People who work more hours than they would like are affected a tiny bit (-2 percent) in the negative direction. Working less than the preferred working hours is worse (-8 percent). The author of the paper suggest that this is because lost consumption rankles worse than lost leisure. But being unemployed is what really hurts. For men there is a dump in life satisfaction by no less than 51 percent, for women the negative impact of being unemployed is 30 percent. So will high unemployment rates give rise to a national depression? It might, unless people come to terms with their situation. My guess is that the negative impact of unemployment is related to a sense of worthlessness and failure. However, being unemployed – in the current state of affairs – seems to have less to do with the worth of the individual, and more to do with a failed system. If people would realize this, they might be able to disassociate unemployment with personal worthlessness and failure.
