Belbin vs Myers Briggs

The Myers-Briggs Type Indicator was developed by Katharine Cook Briggs and her daughter Isabel Briggs Myers, drawing on Carl Jung’s theory of psychological types. Work on the assessment began in the 1940s, with commercial publication following in the 1960s.

MBTI describes personality preferences through four pairs:

One preference from each pair produces a four-letter personality type, such as INTJ, ENFP or ESFJ, creating 16 possible combinations. Each type has an associated description covering preferences, potential strengths, communication approaches and development considerations.

MBTI uses a self-report questionnaire. Good practice involves discussing the results with a qualified practitioner, allowing individuals to explore and verify their best-fit type rather than treating the initial questionnaire result as definitive.

An Important Point: What Myers Briggs Is Not Designed For

The publisher of MBTI explicitly positions it as a development tool rather than an instrument for employee selection. It should not be used to make recruitment decisions, determine suitability for particular jobs or allocate employment opportunities based on personality type.

This is an important distinction when comparing MBTI with Belbin. Belbin can help organisations understand the behavioural contributions needed within an existing team and can inform recruitment and team composition discussions, provided it is used alongside other relevant selection evidence.

Myers Briggs also differs in its theoretical origins from other behavioural frameworks. It draws directly on Jung’s psychological type theory, as does Insights Discovery. DISC, by comparison, originated independently from the work of William Moulton Marston.

Area	Myers Briggs (MBTI)	Belbin
Primary focus	Personality preferences	Contributions to team effectiveness
Framework	Four preference pairs, 16 types	Nine Team Roles
Assessment data	Self-report and best-fit verification	Self-perception and observer feedback
Stability	Preferences are considered relatively enduring	Team Role contributions can change
Main applications	Self-awareness, communication and development	Team composition, development and performance
Team analysis	Comparing individual personality preferences	Dedicated Team Reports
Recruitment	Not intended for selection decisions	Can inform recruitment alongside other evidence
Research origins	Jung’s psychological type theory	Observed behaviour in management teams

Three differences are particularly important.

1. Personality Preferences vs Observed Behaviour

Myers Briggs describes preferences: how individuals naturally prefer to gather information, make decisions and approach different situations. These preferences can provide useful insight into how someone experiences the world and approaches their work.

Belbin focuses on behavioural contribution: what individuals actually do when working with others and how colleagues experience those contributions.

For example, someone may prefer detailed analysis and careful consideration when making decisions. However, their actual contribution within a particular team may be to organise work, support colleagues or drive progress.

Understanding personal preferences is useful. Understanding how those preferences translate into team contribution provides a different perspective. Belbin’s inclusion of observer feedback helps organisations explore that distinction.

2. Enduring Preferences vs Changing Contributions

Myers Briggs is based on the principle that underlying personality preferences are relatively enduring, even though individuals can develop and adapt their behaviour. A person’s reported type may change when completing the questionnaire again, but the MBTI framework generally treats underlying preferences as stable.

Belbin takes a different approach. Team Role contributions are expected to evolve as individuals gain experience, take on different responsibilities or work with different colleagues. Someone who demonstrates strong Shaper behaviour in one team may contribute primarily through Co-ordinator or Implementer behaviour in another.

Belbin therefore avoids defining individuals through one permanent role. Instead, it recognises preferred, manageable and least preferred contributions that can develop over time. This flexibility is particularly valuable when teams change, projects evolve or organisations introduce new responsibilities.

3. Individual Insight vs Team Composition

Myers Briggs primarily describes individuals and their personality preferences. Practitioners can compare different types within a group to explore communication, decision-making and working relationships.

Belbin was developed specifically to understand how different behavioural contributions combine within teams.

For example, a project team might contain several creative individuals who generate excellent ideas but lack sufficient Implementer or Completer Finisher behaviour to translate those ideas into completed work. Alternatively, a team may have strong delivery capability but insufficient Plant or Resource Investigator contribution to explore new opportunities.

Belbin Team Reports can highlight these patterns and help leaders address potential imbalances.

The distinction is straightforward: Myers Briggs helps explain how individuals prefer to operate. Belbin helps explain how their contributions combine to influence team performance.

Limitations of Myers Briggs

One frequently discussed limitation concerns the consistency of questionnaire results over time. Some individuals receive different four-letter types when repeating the assessment, particularly where their scores fall close to the midpoint between two preferences. The MBTI best-fit verification process is intended to help address this, but changes in reported type remain an important consideration.

Another criticism is that MBTI presents personality preferences as either/or categories, when in reality these preferences exist on a sliding scale. This can exaggerate differences between individuals who may actually have very similar preferences.

Research has also questioned the usefulness of MBTI types for predicting occupational performance, consistent with the publisher’s position that the assessment should not be used for employee selection.

These limitations do not remove its potential value as a structured framework for self-awareness and development, provided results are interpreted appropriately.

Limitations of Belbin

Belbin’s nine Team Roles may require a little bit more initial familiarisation than MBTI’s four preference pairs. Observer Assessments also involve some additional administration and depend on colleagues providing thoughtful, relevant feedback.

The psychometric properties of Belbin’s Self-Perception Inventory have been debated in academic research, including a 1993 critique by Furnham, Steele and Pendleton and a subsequent response from Belbin.

An important consideration is that Belbin was developed through research into observed team behaviour rather than as a conventional personality assessment. Its assessment approach incorporates observer feedback alongside self-perception, recognising that individuals may not always have a complete understanding of their own behavioural contributions.

As with any assessment, Belbin results should inform professional judgement rather than replace it.

Choosing between Belbin and Myers Briggs depends on what you want to achieve.

If your objective is to help individuals understand their personality preferences, communication approaches and decision-making styles, Myers Briggs provides a recognised framework for personal development.

If you want to understand why a team performs as it does, identify missing behavioural contributions, allocate responsibilities more effectively or build a more balanced team, Belbin was developed specifically for those purposes.

Myers Briggs helps explain how individuals prefer to think and operate. Belbin helps explain what they contribute and how those contributions work together.

Both perspectives can be valuable. The important thing is selecting the approach that best addresses your organisation’s needs.
