Manifest Needs Theory

One major problem with the need approach to motivation is that we can make up a need for every human behavior. Do we "need" to talk or be silent? The possibilities are endless. In fact, around the 1920s, some 6,000 human needs had been identified by behavioral scientists!

Henry A. Murray recognized this problem and condensed the list into a few instinctive and learned needs. Instincts, which Murray called primary needs, include physiological needs for food, water, sex (procreation), urination, and so on. Learned needs, which Murray called secondary needs, are learned throughout one's life and are basically psychological in nature. They include such needs as the need for achievement, for love, and for affiliation (see Table 7.1).

Murray's main premise was that people have a variety of needs, but only a few are expressed at a given time. When a person is behaving in a way that satisfies some need, Murray called the need manifest. Manifest needs theory assumes that human behavior is driven by the desire to satisfy needs. Lucretia's chattiness probably indicates her need for affiliation. This is a manifest need. But what if Lucretia also has a need to dominate others? Could we detect that need from her current behavior? If not, Murray calls this a latent need. A latent need cannot be inferred from a person's behavior at a given time, yet the person may still possess that need. The person may not have had the opportunity to express the need. Or she may not be in the proper environment to solicit behaviors to satisfy the need. Lucretia's need to dominate may not be motivating her current behavior because she is with friends instead of coworkers.

Manifest needs theory laid the groundwork for later theories, most notably McClelland's learned needs theory, that have greatly influenced the study of organizational behavior. The major implication for management is that some employee needs are latent. Managers often assume that employees do not have certain needs because the employees never try to satisfy them at work. Such needs may exist (latent needs); the work environment is simply not conducive to their manifestation (manifest needs). A reclusive accountant may not have been given the opportunity to demonstrate his need for achievement because he never received challenging assignments.
