If you want to be happy, become more extroverted

People who score highly for extroversion are more likely to have increases in life satisfaction over time.  People who score highly for neuroticism are more likely to have decreases in life satisfaction over time (Headey,2009).

People who are extroverted have a tendency towards: warmth, gregariousness, assertiveness, enthusiasm and feeling energised in company. Whereas people with high Neuroticism scores have a tendency to experience more feelings of anxiety, anger, depression and guilt than those low in neuroticism. People high in neuroticism tend to feel overwhelmed in stressful circumstances; interpret ordinary situations as threatening and have difficulty not acting on urges.

Headey suggests that these differences in life satisfaction as life progresses are because extroverted personality traits are associated with experiencing more positive life events and neurotic personality traits with more adverse life events. Extroverted people tend to build relationships.  Being part of a supportive network of people is strongly associated with happiness, so extroverted behaviour makes life better. Whereas, neurotic people tend to get overwhelmed by their painful emotions and often start to avoid challenging situations. Their lives becomes progressively more narrow.

Our personality may not be as fixed as we thought, on average we tend to become less neurotic and less extroverted with age.

So, assuming we want to be happy with our lives, what might this suggest we should do?  Here are my suggestions:

1. Take the free IPIP Neo test to see how you currently score
2. If you are low in extroversion - accept that you do need time alone to recharge but don't hide away from the world.  Introverts who push themselves to become more social become happier. Work out what your values are around relationships with others. Then try to say 'yes' more often to experiences with others that align with those values. 
3. If you are high in neuroticism - practice mindfulness, get good at noticing what is really happening in the world rather than what your mind is telling you is happening.  Get good at noticing urges to act in 'neurotic' ways and see if you can sit with the urge and instead act in line with your values.  
4. Show yourself compassion - this stuff is harder for you than for happy-go-lucky, bubbly extroverts. 

My personal experience with this?  I have been practising ACT (the approach that much of this blog rests on) for several years now and my neuroticism scores have fallen. This is anecdotal - but I am pretty pleased!
