Beliefs that influence personality likely concern a situation humans never leave.

Many of us-60% of humanity, according to one study-would like to change some of our personality traits, such as decreasing pessimism or neuroticism. Dweck (2008) proposed that traits might be altered by changing beliefs. However, novel beliefs must be identified, she contends, because currently studied beliefs are empirically inadequate (e.g., low correlations to broad personality traits) and because a belief's influence on behavior is usually confined to a particular situation or topic. When psychologists refer to the psychological impact of beliefs about situations, they typically mean local situations: situations individuals can enter and leave (e.g., "This neighborhood is dangerous"). The novel theoretical suggestion of this article is that a person's basic beliefs about a situation they never leave such as the world (e.g., "This world is dangerous") are uniquely suited to impact cross-situational behavior patterns often associated with broad personality traits. Historically, general beliefs about the world (termed "primal world beliefs") were understudied, and many remained unknown, rendering systematic investigation infeasible. However, using several methods that helped identify Big Five traits decades ago, a recent effort seeking to map primal world beliefs found a structure of 26 dimensions (most clustering into the beliefs that the world is Safe, Enticing, and Alive) suggesting promising avenues for primals-personality research. This article presents a nuanced, working, speculative hypothesis future research can explore: Average behavioral tendencies that persist wherever the individual goes (personality traits) theoretically should result from beliefs about the broader situation the individual never leaves (the world).
