The Type Dynamic Indicator (TDI) is a personality assessment similar to the MBTI.

The Type Dynamic Indicator (TDI) is a way of measuring Psychological Type based on Carl Jung’s theory of the human psyche which looks at how and why people change and develop.

Type is not static, it should not be used to put people into a box, but to help people to change and grow.

You should not think of looking at Type as being a fixed 4 letter code, and an excuse for certain behaviour.  People are complex, we all adapt to changes both out there and within.

If you are considering the MBTI Step 1, I suggest taking the Type Dynamic Indicator instead.

When completing the MBTI you may at times wonder what answer to put down, knowing that you will answer differently out of work, when you can be you, and when in work, where you may have had to adapt to suit your working environment.

Type Dynamic Indicator gives you the option to answer questions in 2 different ways

  • The way it is (IS)
  • The way I want (WANT)

So, if you are unhappy in your job but not sure why, you will find that this Type Dynamic Indicator (TDI) assessment pinpoints the areas of conflict. My clients love this!

I use the Type Dynamic Indicator with clients to help them gain greater self-insight and for growth and change.

Using the Type Dynamic Indicator, we look at expressed preferences, alongside sub-personalities, as our personality is made up of many different parts of ourselves.

Recognising that people can view themselves in different ways, you answer the Type Dynamic Indicator questionnaire from two perspectives – ‘the way it is’ and ‘the way I want’ through 64 questions. This is much more helpful than trying to answer from a general perspective as we can often behave differently in work and at home.

This provides more richness to a more typical measure of type – e.g. we can demonstrate high level of energy in our personal life but lack energy in work.

  • Extraversion and Introversion– 2 different orientations towards the inner (internal, subjective, private) or external world (objective, physical and shared)
  • Sensing and Intuition– 2 different ways of receiving information. Via our senses (immediate, realistic and empirical) of via patterns, and seeing things as part of the bigger picture rather than a focus on hard facts and details).
  • Thinking and Feeling– 2 different ways of dealing with and evaluating information. Thinking is rational and systematic and reaches decisions through logical deliberations. Feeling reaches decisions based on personal values and does not need explicit logic and reasons. Feeling is not the warm and fuzzy measure that can come from some other measures.
  • Judging and Perceiving, covered by some Type measures is not part of Jung’s theory but included in the TDI and looks at lifestyle.

The Type Dynamic Indicator is helpful to

  • Understand ourselves better– we often do things so naturally, we get into habits, and we may not take the time to think about what we are doing, why we are doing it, and what impact it may have on others.
  • Understand others better– we meet and work with lots of different people who have different styles, interests and needs which we cannot always identify or articulate.
  • Building better relationships– if we want to get the most out of our relationships and interactions, we all need to be more aware, which in turn allows us to become more flexible ourselves and more tolerant of differences.

The ‘4 Self’s Model’

In the Type Dynamic Indicator questionnaire, you will be asked to answer every question from two points of view – ‘the way it is’ and ‘the way I want’. The ‘4 Self’s Model’ will help you to understand what this is getting at.

Think of how you behave in different circumstances.

In a typical day you may switch between being a controlling parent, a relaxed friend and a facilitative manager. These are part of who you are. This is called the Contextual Self, as the self that is presented/ expressed will reflect the needs of the situation.  As a parent we may need to control when our child is in danger.

An actor can play different roles; think of Gary Oldman playing Winston Churchill, Sid Vicious, Count Dracula and George Smiley (amongst many others) but never loses sight of who he/she is.

When you complete the questionnaire, don’t confuse the work role with your own identity, you are able to answer in two different ways:

Respond as you behave in your current work role, this is your Identity Self.

Respond as you would like it to be ‘the way I want’ which is your Ideal Self.

The 4 Self’s model also includes the Unconscious Self.

An understanding of both ‘the way it is’ and ‘the way I want’ will help to identify natural preferences. This doesn’t mean you can’t do things in a different way, just what comes more natural to you.
