Construct and concurrent validity<br />
The other two factor analytic studies were designed<br />
to establish construct validity and involved<br />
a considerable number of other instruments as well<br />
as the HBDI. The second of these analyses was based<br />
on the current version of the HBDI. Cognitive ability<br />
measures, the Myers-Briggs Type Indicator (MBTI),<br />
Kolb’s Learning Style Inventory (LSI) and 11 other<br />
measures of thinking <strong>styles</strong> and <strong>learning</strong> strategies<br />
were included. The sample comprised 182 students.<br />
The analysis yielded two higher-order factors.<br />
The first was a bipolar factor, contrasting the<br />
Herrmann C and A quadrants, with significant loadings<br />
on extraversion-introversion, a preference for <strong>learning</strong><br />
in groups, <strong>learning</strong> through personal experience,<br />
visual imagery and Kolb’s ‘concrete experience’ scale.<br />
Bunderson (cited by Herrmann 1989) suggested<br />
that there is conceptual congruence between this<br />
bipolar factor and Witkin’s dimension of field<br />
dependence-independence. The second factor had<br />
relatively lower loadings, but contrasted Herrmann’s<br />
D and B quadrants and had something in common<br />
with the Myers-Briggs perceiving-judging and<br />
intuition-sensing categorisation, as well as with six<br />
other measures suggesting a non-verbal, divergent<br />
thinking preference.<br />
It is of interest that one of the HBDI factors was<br />
more closely related to measures from the MBTI than<br />
from Kolb’s LSI. In an earlier factor analytic study<br />
by Bunderson, the largest single factor also contrasted<br />
the D and B quadrants and had relatively high<br />
loadings from the same two Myers-Briggs measures<br />
(perceiving-judging: 0.61; and intuition-sensing: 0.69).<br />
The correlation between the HBDI and the Myers-Briggs<br />
measures of extraversion-introversion was 0.73.<br />
Bunderson suggested that the overlap between<br />
the two instruments was such that the item clusters<br />
‘may ultimately be explainable by a common set<br />
of constructs’ (cited by Herrmann 1989, 377).<br />
At a conceptual level, Herrmann’s model shares<br />
important features with those of theorists other than<br />
those mentioned above. Gregorc’s Mind Styles Model<br />
has four quadrants which correspond closely to<br />
those of Herrmann, but which are differently organised<br />
in that abstract sequential qualities, resembling those<br />
of Herrmann’s theorists, are diametrically opposed<br />
to those of Herrmann’s innovators, and concrete<br />
sequential qualities, resembling those of Herrmann’s<br />
organisers, are contrasted with those of his<br />
humanitarians. The lack of factor analytic support<br />
for Gregorc’s model (see Section 3.1) contrasts with<br />
the relatively strong support provided by Bunderson<br />
for that of Herrmann.<br />
Among the theorists whose models are conceptually<br />
related to that of Herrmann are Allinson and Hayes<br />
(1996), who contrast left-brained analysis with<br />
right-brained intuition. McCarthy’s 4MAT model (1990)<br />
includes what she calls ‘right mode’ and ‘left mode’<br />
phases. Kirton (1976) distinguishes between adapters<br />
and innovators just as Herrmann does between<br />
organisers and innovators. Sternberg’s descriptions<br />
(1999) of legislative, executive and judicial thinking<br />
<strong>styles</strong> bring to mind Herrmann’s innovators, organisers<br />
and theorists respectively.<br />
It is also possible that there is some connection<br />
between the opposition of the B and D quadrants<br />
in Herrmann’s model and motivational features in the<br />
Dunn and Dunn model (Dunn and Griggs 2003) and<br />
in Apter’s (2001) model of motivational <strong>styles</strong>. It is likely<br />
that Herrmann’s creative innovators are sometimes<br />
non-conforming and do not welcome structure, unlike<br />
organisers. In Apter’s terms, Herrmann’s B-D axis<br />
offers possibilities of reversal within the means-ends<br />
and rules domains, while the A-D axis offers reversal<br />
within the transactions and relationships domains.<br />
Herrmann’s interest in the need to develop stylistic<br />
flexibility fits well with Apter’s concept that reversing<br />
between opposites increases the likelihood of<br />
psychological satisfaction.<br />
Herrmann’s concept of harmonious and conflicting<br />
combinations of quadrant preference receives some<br />
support from the distribution of double dominance<br />
profiles found in a large UK sample (Martin 2003).<br />
‘Harmonious’ combinations (A-B and C-D) are the most<br />
common patterns in the database of 3400 profiles<br />
(62%), followed by the upper (A-D) and lower (B-C)<br />
pairings (31%) and then by the conflicting diagonal<br />
pairings (A-C and B-D) which occur in only 7% of cases.<br />
Gender, ethnic and occupational differences<br />
Although Herrmann (1996) had no theoretically based<br />
reasons for predicting gender effects, it soon became<br />
clear that there are very substantial gender differences<br />
on the HBDI. These boil down to a strong male<br />
preference for the A (theorist) quadrant and a strong<br />
female preference for the C (humanitarian) quadrant.<br />
The same pattern is apparent in Martin’s (2003)<br />
UK sample, where the gender ratios are often<br />
greater than 3:1 for dominant profiles. It is not clear<br />
how far these large gender-related differences are<br />
socio-culturally determined, or indeed whether they<br />
are self-presentational rather than behavioural.<br />
However, there is a striking similarity between what<br />
is revealed by the HBDI and Baron-Cohen’s portrayal<br />
(2003) of ‘systematising’ (male) and ‘empathetic’<br />
(female) brains.<br />
It is abundantly clear from the Herrmann Group’s<br />
international database that ethnic differences<br />
are minimal or non-existent. Herrmann (1996) presents<br />
virtually identical mean profiles for Blacks, Hispanics,<br />
Native Americans, Asians and Whites.
