In spite of the specific entrepreneur prediction of the HBDI, there does not appear to be any published research that has tested this relationship.
We expected to find that only the Quadrant D subscale of the HBDI would discriminate between entrepreneurs, owner-managers, and non-entrepreneurs, and that the entrepreneur group means for the Quadrant D subscale would be significantly higher than the means for the other two groups.
We expected to find combinations of the EQ, the EAO subscales, the MBTI subscales, and the HBDI subscales that would give greater discrimination between entrepreneurs and non-entrepreneurs than would any single scale or subscale.
The MBTI and HBDI were professionally scored, while one of the authors calculated the scores for the EQ and the EAO.
Brief summaries of the MBTI and HBDI were returned to participants with the instruction that "Each of these instruments is meant to be administered by a professional and the output interpreted by a professional.
The EQ and EAO provide interval data, whereas the MBTI and HBDI result in categorizations based solely on interval data.
The EQ, EAO, and HBDI produced interval scores directly usable in the statistical analyses.
Table 1 shows the univariate F-scores and probabilities for sex, group, and the sex by group interaction for the EQ scale and the EAO, MBTI, and HBDI subscales.
Of the four HBDI subscales, the Quadrant B and Quadrant D subscales were not significantly different for men and women (Table 2 lines 10-13).
Our final research question dealt with whether we could find combinations of the EQ, the EAO subscales, the MBTI subscales and the HBDI subscales that would give greater discrimination between entrepreneurs and non-entrepreneurs than would any single scale or subscale.
The HBDI Quadrant A and Quadrant C, the EAO SE and INN, and the EQ univariate ANOVAs were all significant.
There were, however, two significant univariate ANOVAs: the EAO SE and the HBDI Quadrant B scores.
