Extraverts have lower
savings rates than introverts. Three studies at the University of Toronto in
Canada showed that people with higher levels of extraversion are less likely to
save for the future. UT researchers also predicted that particular personality
traits may have a powerful influence on a country’s economic outlook (Association for Psychological Science,
September 15, 2015).
Jacob Hirsch,
psychological scientist at the University of Toronto, said previous research
showed that higher levels of extraversion were associated with the preference
for immediate gratification over delayed rewards. When people were asked to
choose between smaller immediate rewards or larger delayed rewards, extraverts
were more likely to choose the smaller, but immediate, option. Hirsch wanted to
extend the research to record savings habits between extraverts and introverts.
A comparison of
American national savings rates with personality traits from 1966 to 1993
revealed that the higher the population’s rate of extraversion, the less likely
they tended to save. Data was collected from 16,846 American college students
and compared with data on national savings rates. As US savings rates sharply
declined, levels of extraversion increased.
A second study looked
at state-level data and it showed a similar trend. Data on personality traits
were collected online between December 1999 and January 2005 as part of a
larger study on personality and geographic location. Hirsch standardized the
personality data from the 619,397 online respondents into state-level scores
for each of the five major personality dimensions. He calculated household saving
behaviour within each state on disposable income, savings, and consumer
confidence from the Department of Commerce and Bureau of Economic Analysis. The
result showed that households in more ‘extraverted’ states of America tended to
save less than households in less ‘extraverted’ states.
The third study
examined international data to determine the global trend across 53 countries.
It revealed that higher levels of extraversion were associated with lower rates
of personal savings.
Across the three
studies, the UT findings supported the view that population variation in
micro-level personality characteristics can be an important factor in
predicting macro-level social outcomes, stated Hirsch. Relatively extraverted
populations are more prone to spending than saving.
However Hirsch
cautions that just because there was a pattern across the three studies, the
results were correlational and no firm causal conclusions could be drawn.
Hirsch documented the findings of his research in the journal, Personality and Individual Differences.
