Essentials of Myers-Briggs Type Indicator Assessment (Naomi L. Quenk):
“Table 4.1 gives the type distribution for the national representative sample of U.S. adults as reported in Myers, McCaulley, Quenk, and Hammer (1998). (...)
Some client concerns may be related to being a type that is infrequent in the population at large or in a particular setting.
For example, only about 25% of the U.S. population prefer Intuition over Sensing, with INFJ least frequent among males (1.2%) and ISTJ (16.4%) the most frequent; INTJ are the least frequent among females (.9%) and ISFJ (19.4%) the most frequent.
When a person of a more rare type reports feeling different, like an outsider, or misunderstood, it may be helpful to validate that perception with statistics. (...)
Awareness of some general societal biases toward particular preferences or whole types can also be helpful in understanding and helping a client cope with specific issues. For example, many Introverts struggle with such labels as ‘shy,’ ‘unsociable,’ ‘cold,’ or ‘uncommunicative.’
Even though the national representative sample indicates about an equal frequency of people reporting a preference for Extraversion and those preferring Introversion, our culture in general clearly favors extraverted qualities over introverted ones.”
