5.1 Differences in People and Personality Preferences

Key Takeaways

  • CM3 describes differences through four preference pairs: Extravert-Introvert, Sensing-iNtuiting, Thinking-Feeling, and Judging-Perceiving
  • Judging types prefer situations to be cut and dried, working to a timetable in a systematic and methodical way
  • Sensing types focus on definite detailed facts, while iNtuiting types are big-picture people who enjoy concepts and theory
  • An Introvert with a Sensing preference tends to support careful incremental change, while an Extravert with iNtuiting preferences favours dramatic immediate change
  • The aim is to look for the strengths each person contributes rather than to label or exclude

The People and change syllabus area opens with individual differences, because how someone responds to change depends heavily on personality preferences. CM3 lists several ways of describing differences — personality profiles, types, talents, preferences about receiving information, and learning styles — and examines the four-pair type model in detail.

The four preference pairs

Extravert (E) — Introvert (I)

Extravert: energised by the external worldIntrovert: energised by their own inner world
Likes talking to people, being sociableEnjoys their own thoughts and feelings
Likes to learn by activity and talkPrefers writing to express ideas
Lots of interestsFewer, more serious interests
Speaks first, thinks about it laterThinks before they speak
Likes starting new thingsA reflective learner

Sensing (S) — iNtuiting (N)

The N abbreviation avoids confusion with Introvert.

Sensing: focuses on sensory dataiNtuiting: focuses on interpretations and intuitions
Focuses on what their senses tell themA big-picture person
Pays attention to definite, detailed factsEnjoys concepts and theory
Notices things in an orderly wayLooks behind facts for meaning
Likes getting information in clear stages

Thinking (T) — Feeling (F)

Thinking: decides with logicFeeling: decides with values
Treats problems with logicDecides with empathy and consideration for others
Cause-and-effect reasoningWith compassion
Tough mindedBased on values and beliefs
Looks for the objectively right answerSeeks a widely accepted outcome
Appreciates just solutionsOpen to and accepting of others

Judging (J) — Perceiving (P)

Judging: prefers things cut and dried and clearPerceiving: prefers open-ended, ambiguous situations
Working to a timetableSpontaneous
Systematic and methodicalHappy with ambiguity
Likes to planLikes to be flexible and adaptable
Appreciates closure on decisionsDislikes restrictive systems and detailed plans
Dislikes the pressure of leaving things latePositively enjoys urgent work

The descriptor systematic and methodical belongs to Judging and is a favourite exam item, because candidates instinctively associate methodical working with Sensing. Sensing is about what information you attend to; Judging is about how you like to organise and close things down.

Preferences at work in learning

Preferences shape how people want to be taught:

  • People with a strong Sensing preference are likely to appreciate more detailed instruction; those with the opposite iNtuiting preference prefer more open-ended approaches
  • Those with a strong Thinking preference typically seek more rigorous logic in their learning and less personal support than those with the opposite Feeling preference

The practical implication for a change manager designing training: a single format will serve part of the audience well and part badly. Offering the detailed step-by-step guide and the one-page conceptual overview is not duplication — it is coverage.

Preferences at work in change situations

Type preferences also affect attitude to change, and CM3 gives four specific combinations:

CombinationLikely attitude to change
Strong Introvert + SensingA thoughtful, down-to-earth approach that supports only careful, incremental change
Strong Extravert + iNtuitiveLikely to favour engaging with others in dramatic and immediate change
Introverted iNtuitiveFavours ideas and vision
Extraverted SensingWants to organise immediate action

This is genuinely useful when reading a stakeholder. A senior manager who keeps asking for more detail and pushing back on timescales may not be resisting the change at all — they may be an Introverted Sensing type doing exactly what such a person does with an ambitious proposal. Responding with more enthusiasm is precisely the wrong move; responding with detail and a phased plan is right.

Conflicts and complementarity

The purpose of the model is not to sort people into boxes. CM3 is explicit: the ideal is to look for the strengths that each person can contribute to a given situation.

The worked example given is a meeting to discuss the impact of change on a work group. The Thinking person brings objectivity, rationality and care for fairness, all of which matter to a good outcome. The Feeling colleague brings a natural sense of humanity and sensitive understanding of the people involved, which also matters. Ideally we value both while respecting the different preferences from which they come — and if the two individuals can begin to understand and respect each other's contribution, they could begin to make a great team.

That framing matters for the exam and for practice. Questions that offer an option about excluding a personality type, or matching people to changes they will find comfortable, are testing whether you have understood that the model is about harvesting difference, not managing it away. It connects directly to the later material on team diversity, where diverse teams with high psychological safety outperform teams of similars.
