Genetics and happiness
80% of happiness is genetic
For facets, additive genetic A and non-shared environmental variance E shown. Which traits, and which particular facets, are most important for promoting or obstructing individual life satisfaction? For example, a personality disposition to experience positive emotions may contribute to many episodes of joy and enthusiasm. Another meta-analysis by Bartels 6 , with somewhat different inclusion criteria, samples and analytic strategy reported an average heritability of 0. We think we know a lot about the environment but we do not. Further, both personality and life satisfaction are influenced by genetic factors 5 , 6 , 7 , 8 , but we have inadequate understanding of the role of genetic and environmental factors in explaining the links between personality and life satisfaction. Q What constitutes an act of kindness? Thus, for the biometric analyses disentangling genetic and environmental effects we focused on these four facets with substantial and significant effects. Heritability of life satisfaction was 0. Further, although levels of life satisfaction commonly vary only moderately with age, there might be age-related moderation of genetic and environmental factors. Source: opto. But it is important to note that this particular study has a limited sample. Fifth, whereas prior studies have examined samples with broad age ranges, we wanted to examine a specific period in life — middle to late adulthood — to assess how relatively stable personality characteristics contribute to life satisfaction in a life course perspective.
The current findings are noteworthy in identifying personality facets that have certain connections to these four goal-state conditions.
Our findings accord with previous studies in identifying depression, and partly positive emotions, as central predictors of life satisfaction 52 Q A bit like how a football player would see the club doctor and the physiotherapist after an injury?
Happiness would be an inappropriate emotional reaction to every situation. Some people may find it easier to increase their happiness, whereas others may need to invest more effort into it.
Thus, life satisfaction appears to be somewhat more influenced by environmental factors than other dimensions of wellbeing. There were three genetic variants for happiness, two that account for differences in symptoms of depression, and eleven locations on the human genome that may account for varying degrees of neurotic behavior.
