Applying item response theory procedures to examine the MBTI, Harvey and Murry (1994) found that the dichotomizing procedure produce between 26% and 32% loss of information for each of the scales. These observations are troublesome as there are notably little data to support thetype structure of the MBTI. Furthermore, the practice of converting scale scores totype categories reduces any predictive value that the test may afford. Consequently, those who use the conventional MBTI scoring practice to make inferences about others’ personality risk reaching conclusions that cannot be empirically justified.
拿依家到RESULT 有幾STEADY.
Howes and Carskadon (1979) provided
data that raise additional and equally important
questions regarding the reliability
of the four-letter type score. Their analysis
indicated that a large portion of their participants
received different type profiles
when retested. Not surprisingly, the greatest
proportion of changes occurred when
the initial preference score was close to the
middle of the scale (1 to 15 points on either
side of the midpoint). When the initial
score was within this intermediate range,
32% of the EI, 25% of the SN, 29% of the
TF, and 30% of the JP labels shifted on the
second testing. McCarley and Carskadon
(1983) replicated these findings and demonstrated
that across a 5-week test-retest
interval, 50% of the participants received a
different classification on one or more of
the scales. Indeed, Myers et al. (1998) reported
that 35% of individuals had a different
four-letter type score after a 4-week
interval.
These results are not surprising given
the center-heavy distribution and heterogeneity
of variance of the scale scores. Nor
are these changes trivial. If we are to presume
that “an extraverted sensing type will
show extraversion differently from an extraverted
thinking type” (McCaulley, 2000),
then the alteration of one or more of the
four-letter type formula represents a considerable
change in personality.
我唔係聰明人，但一樣野行左60幾年，咁多人咁多大公司用，真係完全冇用？呢d大公司入面講學歷，phd 多不勝數啦。
見到你提供好多資料反對mbti, 但點解佢仍存在？今日同人講地球係平都唔會有人信啦。其實按你講心理學都好多唔同分支，會唔會亦有學者支持mbti呢
另外呢到第一個post 提供既根本唔係mbti. 你一定知mbti 都有一定要求點去做assessment. 所以呢到有人self fulfill 一d都唔出奇啦
