Boy Band NCT Dream Cash in on Personality Test Fad

Boy band NCT Dream dropped a new album, "ISTJ," inspired by the Myers–Briggs Type Indicator (MBTI) personality test, on Monday.

ISTJ is one of 16 personality types identified by the test, indicating a person who is introverted, rational and organized -- the opposite of the ENFP character type, which refers to a person who is spontaneous, extroverted and empathetic.

The MBTI test is growing in popularity among young people in Korea.
