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.
