Problem: The theory of self-actualization has been criticized for its lack of empirical support and for its suggestion that people must have lower needs met before self-actualization is possible. In 1976, Wahba and Bridwell investigated these issues by reviewing several studies exploring different parts of the theory. They found only inconsistent support for the theory and limited support for the proposed progression through Maslow's hierarchy. However, the idea that some people are more motivated by B-needs than D-needs was supported by their research, lending increased evidence to the idea that some people may be more naturally motivated toward self-actualization than other.
