According to Maslow, when a person's needs are not met, they can experience a variety of negative consequences, including frustration, anxiety, apathy, withdrawal, aggression, violence, depression, and suicidality.

Maslow's hierarchy of needs is often represented as a triangle, with the most basic needs at the bottom and the most complex needs at the top.

Maslow's hierarchy of needs is based on empirical evidence, including studies of people from different cultures and backgrounds.

Maslow's hierarchy of needs remains a popular and influential theory because it is simple and easy to understand, it is based on empirical evidence, it is applicable to a wide range of people, and it is a humanistic theory that focuses on the whole person.

The most important level of needs in Maslow's hierarchy depends on the individual and their circumstances. For some people, physiological needs may be the most important, while for others, self-actualization needs may be the most important.
