INFP (introversion, intuition, feeling, perception) is an abbreviation used in the publications of the Myers-Briggs Type Indicator (MBTI) to refer to one of sixteen personality types. The MBTI was developed from the work of prominent psychiatrist Carl G. Jung in his book Psychological Types. Jung proposed a psychological typology based on the theories of cognitive functions that he developed through his clinical observations. From Jung's work, others developed psychological typologies. Jungian personality assessments include the MBTI assessment, developed by Isabel Briggs Myers and Katharine Cook Briggs, and the Keirsey Temperament Sorter, developed by David Keirsey.
INFPs are driven by a strong sense of right and wrong and a desire to exercise their creativity, even if only behind the scenes. Their weaknesses may include sensitivity to criticism, poor organization, and low assertiveness. Keirsey referred to the INFPs as Healers, one of the four types belonging to the temperament he called the Idealists. INFPs are somewhat rare, accounting for about 4% of the population.
According to Myers-Briggs, INFPs focus much of their energy on an inner world dominated by intense feeling and deeply held ethics. They seek an external life that is in keeping with these values. Loyal to the people and causes important to them, INFPs can quickly spot opportunities to implement their ideals. They are curious to understand those around them, and so are accepting and flexible unless their values are threatened.
According to Keirsey, based on observations of behavior, notable INFPs may include Princess Diana, George Orwell, Aldous Huxley, Audrey Hepburn, Richard Gere, Albert Schweitzer, and Isabel Briggs Myers (self-reported to the test she invented with her mother, Katharine Cook Briggs). 16 personalities also infers that William Shakespeare, J.R.R. Tolkien, Johnny Depp and Julia Roberts may be INFPs.
