What you spend your money on may reveal a lot about your personality type. Those who are more open to new experiences spend more on flights and travel, while extraverts spend more on eating out. People with higher levels of neuroticism spend less on home loan repayments. Those who are more agreeable donate more to charity.
The majority of replication attempts of previous studies linking personality traits to life outcomes are successful. However, the associations may not be as strong as reported in the results originally published.
