MBTI Form M Manual Supplement
Somewhat densely written. Intended for professional type practitioners, this 17 page guide discusses the MBTI test (version M): correlations, validation, reliability, cross-cultural applications, etc. Of particular interest is the adjective list on page 11, which will tell you which types tend to be perceived as "original," "forgiving," "opinionated," etc. (Societal bias warning.) Also contains some interesting material on how well the MBTI can identify each type, i.e. INTJs are the most mistyped type, followed by INTPs.
