Information suggesting introversion was considered negative while information suggestion extroversion was considered to be positive.
Hence, the consistent influence of extroversion on participation is entirely sensible.
They are tending to be drawn away from introspection and self-pity towards a degree of extroversion and a realisation that they have become members of a wider community.
Through his research he found that around the age of 30, neuroticism and extroversion begin to decline, while agreeableness and conscientiousness increase with age.

For example, as voting is a personal and private act, extroversion, which favours social interactions, may not affect the propensity to turn out.
However, the relationship between extroversion (and neuroticism) and subjective happiness is only partially mediated by self-efficacy.
Although these findings enjoy considerable theoretical and intuitive appeal, research on individual differences in rates of political participation is hardly rife with attention to extroversion.
