How you spend your money can signal aspects of your personality, according to research published in Psychological Science, a journal of the Association for Psychological Science. Analyses of over 2 million spending records from more than 2,000 individuals indicate that when people spend money in certain categories, this can be used to infer certain personality traits, such as how materialistic they are or how much self-control they tend to have.
