Intrapersonal intelligence refers to one's awareness and understanding of oneself, according to Howard Gardner's theory of multiple intelligences. Gardner proposed that people possess different types of intelligence and may be particularly strong in some types and weak in others. Those with high intrapersonal intelligence have a clear understanding of themselves and what they need in different settings. They tend to be self-reflective, perfectionistic, and prefer working alone. While they can lack interpersonal skills, developing these abilities through group work is important to prevent isolation. A lack of intrapersonal intelligence may contribute to inconsistent choices and failure to develop life goals.
