Ashridge Management Type Research
Background of the MBTI
One of the most widely used personality instruments, the Myers-Briggs Type
Indicator provides a useful tool for understanding differences between people.
The instrument offers individuals an insight into where they get their energy from,
how they take in information and make decisions, and the way they prefer to live
their lives.
The tool has many different applications including helping people to understand
why they may find some occupations more rewarding than others and why
certain roles can provide frustrations. Each of the 16 types has its own strengths
and areas for development; however, it does not give an indicator of skills or
abilities. The MBTI only really adds value when used in a developmental setting.
The MBTI has been used world-wide across many different languages and
cultures. Research has suggested that type theory is meaningful across all
cultures but the expression and interpretation of behaviours will vary according
to culture (Kendall, 1998). This means that it is particularly useful in global
management development and can be used with audiences other than the white,
middle class Americans on which the original research was based.
The MBTI has a long history and many people have written and researched
about the development and application of type. Ashridge research aims to build
upon some of these previous studies: specifically, the 1998 research project
carried out by Oxford Psychologists Press (Kendall, 1998), which has been used
as a basis for comparison with the Ashridge data. This research, which was part
of the validation study of the UK form of the MBTI, presented the first type tables
for the UK population. The OPP study aims to provide ‘an important benchmark
for many research initiatives such as exploring similarities and differences with
other countries and cultures’ (Kendall, 1998, p5). The Ashridge study aims to
develop and build upon some of these research initiatives.
The data
Ashridge, one of the world’s leading business schools, delivers executive
education and development to individuals and organisations. As well as having
a comprehensive portfolio of open programmes, Ashridge provides tailored
programmes to a range of client organisations that span all industry sectors.
Every year, about 5000 managers attend programmes at Ashridge; of these
42% are international programme participants. Many of these programmes have
aspects of individual and team development for which participants complete
a range of psychometric instruments, one of which is the MBTI. The data was
collected from managers who have attended a variety of the programmes.
The research was carried out in January 2011 using the reported types of over
22,000 managers who have attended both open and tailored executive education
programmes in the past ten years. When the data was collected, permission was
sought to use the findings for research purposes, and all data was anonymised.

Ashridge MBTI Research into distribution of type
The sample population
Subjects in this research were all participants on management development
programmes at Ashridge from 2000 to 2010. The participants ranged in age from
20 to 78. Management levels ranged from junior manager to senior executive
and chief executive. The participants in this sample population came from
116 different countries: 96% were European, with 52% of the total population
coming from the UK. The gender split was 76% male and 22% female with 2%
unspecified. The largest individual industry sectors are manufacturing with 24%,
and public sector workers with 25% of the sample population.
Aims of research
The research had the following aims, the findings of which are summarised later:
n to build on previous research and explore further some of the differences that
exist in the distribution of types
n to compare managerial type tables with the UK population and examine
differences that exists. Anecdotal evidence suggested that some types
more than others seemed to appear in management. The research aimed to
discover the extent to which this is true and, if this is the case, which were the
more prevalent
n previous research has suggested that there are some gender differences
in the MBTI, specifically around the dichotomies of Thinking and Feeling
(Kendall, 1998). This research aimed to see if these patterns still held true
when looking at a managerial population
n limited research has examined differences in type distribution within Europe.
This research aimed to see if there were any significant differences in the
distribution of type for European managers
n again, limited research is available about the distribution of managers across
industry sector. This research aimed to go some way to providing this data
n finally, to provide resources for MBTI users to use with their clients both
individually and at an organisational level.
The findings
The MBTI is different from many other psychometric instruments in that it is not
normative; therefore it is more useful to look at whole types and the frequency
with which they appear in different populations. Research has been carried out
on the population distribution of type within the UK (Kendall, 1998) and this
study aimed to extend this by looking at type distributions for managers across
different countries and industries.
To be able to make conclusions on whether a certain group of people differ
significantly in the type distribution to the general population, we used a formula
called the Self Selection Ratio (SSR). This calculates whether a certain type is
more or less likely to self-select into an area than would be suspected. A score
of greater than one means that more of that type than would be expected are
found in this area, a score of less than one shows an under-representation of
this type, while a score of one means you would find as many as the general
population mean.

Ashridge MBTI Research into distribution of type
n Modal types
The modal type for Ashridge’s management population is ESTJ (22.5%), followed
by ENTJ, ISTJ and ENTP. The least frequent types are ISFP, INFJ, ESFP and
INFP.
This demonstrates the most pronounced findings; the under-representation of
people with a Feeling preference in management. 86% of Ashridge managers
had a reported Thinking preference compared to the general population where
46% had this reported type. Also pronounced was the difference in Sensing and
Intuition; in the management population, this was split 50/50: however, in a UK
population only 23% of people report a preference for Intuition.
n Gender differences
In the UK population, the Thinking-Feeling dichotomy is the only one that
shows some gender differences, with women being more likely to report a
Feeling preference than men (70% women compared to 35% men). This
pattern does not hold true for a managerial population, where more women
(76%) had a reported preference for Thinking. This is the same pattern that
male managers display. This finding would provide the basis for interesting
research into why this occurs; are women managers more similar to their
male counterparts, or do they adopt behaviours that they see as the norm in a
managerial population?
n European differences
The UK managerial patterns are also true when looking at Europe. Across
the European countries represented in the type tables, the modal types seem
to be ESTJ, ENTJ and ISTJ followed by ENTP. Over half of all European
managers had a TJ preference.
n Industry differences
Industry sector type tables were calculated by breaking down the total
Ashridge type table into industry sectors. Self-selection ratios were used to
look at how specific industry sectors compared to the general managerial
population. For most industries there were no significant differences in type
distribution according to the industry sector. Some differences did occur:
for example, in retail, ENTP was over-represented compared to the general
managerial population. However the modal types still remained the same with
ESTJ, ENTJ and ISTJ dominant.

Summary of findings
The research showed that there are differences in the type distributions of
managers compared to a UK population, more specifically:
n Some types are more prevalent than others in management and these seem
to be largely focused in the four corners of the type table (ESTJ, ENTJ, ISTJ
and INTJ)
n Gender differences do not appear to exist in a managerial population, with
as many male managers reporting to have a Thinking preference as female
managers. The striking difference though is in the prevalence of managers
generally reporting to have a Thinking preference and the under-representation
of managers with a Feeling preference.
n Type tables for European managers show no significant difference in profiles
across different countries
n There does not appear to be a significant difference in managerial types
across different industry sectors.
Conclusion
The main aim of the research was to provide type practitioners with up-to-date
type tables. The research indicated that there are some significant differences in
the types found in management compared to the general UK population.
The Ashridge study has raised some interesting questions that could form the
basis for further research. For instance, the research was based on reported
types and it would be useful to see how this may differ from their ‘best-fit’.
More specifically, looking at some of the biases that seem to occur, it would be
valuable to gain an understanding of whether managers are recognising that in
order to cope with a managerial role, they need to develop the ability to behave
in ways typically reported for ESTJ, ENTJ, ISTJ or ENTP types.
