Answering the MBTI critics Kerwin directly addresses criticisms of the MBTI, many of which can be traced back to misconceptions about the instrument, its framework, intended uses, or biases about personality assessments altogether. The paper answers the most pressing questions regarding the assessment, including:

“The MBTI assessment isn’t reliable”. Articles that criticize the MBTI assessment often quote a statistic from David Pittenger that claims a 50 percent retest rate over a 5-week retest period. Yet this widely circulated number originates from a 1993 study citing an even older 1979 [1] study based on an outdated form of the MBTI, not the current version of the instrument. Research in the MBTI Manual shows that over a 4-week retest period, 65 percent of respondents had all four preferences the same, and 93 percent had three or four the same. [2] The MBTI Form M Manual Supplement (2009) shows test-retest reliabilities up to four years ranging from .57 to .81 and one-month test-reliabilities of .94 to .97. [3]
