A theory of constructed human response.

CDT explains how a person constructs self, other people, context, meaning, choice and response in real time—and how awareness changes what becomes available to construct. [1]

CDT does not begin by asking what type of person you are. It asks what you were able to notice, choose and construct in this moment.
In plain English

People do not simply respond to situations. They construct what the situation means.

Every response has a construction behind it: what the person intended, noticed, ignored, interpreted, felt able to choose and ultimately enacted.

Much of this process happens habitually and outside immediate awareness. A familiar response can therefore feel like personality, truth or inevitability even though it is being constructed through repeated patterns of thinking.

CDT makes that process available for examination. Within CDT, development concerns becoming more able to notice the construction, hold greater complexity and choose a response deliberately rather than reproduce it automatically.

A simple example

Two people can enter the same meeting. One constructs challenge and becomes curious; another constructs threat and becomes defensive. The event is shared. The available awareness, meaning, choice and response are not.

The organising architecture

Intention → Awareness → Choice → Response.

IACR is CDT’s core developmental architecture. It describes how intention moves into constructed response, with Awareness as the point at which construction can become visible and another choice may become usable. [1] [2]

Intention

What is the person trying to achieve, protect, avoid or preserve—and which habitual cognitive routes are shaping that intention?

Awareness

How much of that construction can the person currently notice, including their own thinking, emotion and effect on others?

Choice

Which alternatives are genuinely available once the person becomes more aware of the construction and its context?

Response

What becomes visible in behaviour after intention has moved through the awareness and choice available in that moment?

IACR is recursive, not a four-step decision checklist. Responses and consequences reshape the next encounter. Construction is the underlying activity between intention and response; awareness concerns its visibility. Noticing a habitual frame does not guarantee that an alternative can immediately be enacted.

The working components

The current theory gives each construct a job.

What began as a set of related ideas has developed into an integrated architecture for observing construction and development.

Cognitive Intentions →

Directions of cognition through which people construct attention, meaning, motivation and response. The framework developed from Meta-Programmes and reframes their use around intention, polarity and awareness. CIs describe contextual construction, not personality identities.

Thinking Style

The context-sensitive combination of Cognitive Intentions a person uses regularly. It describes a preferred route of construction rather than a fixed personality type.

Dynamic Intelligence

The live ability to recognise and navigate construction from intention through awareness and choice into an effective response.

Awareness Quotient →

The current developmental model and proposed measure of dynamic awareness: how aware a person is of constructing with their available cognitive structure, in a particular moment and context.

Thinking Quotient →

In current terminology, TQ concerns structural cognitive complexity: the capacity to hold perspectives, systems, principles, contradictions and transformations of frame. This must be distinguished from awareness of using that structure.

Zone of Dynamic Development →

The developmental space between a current automatic construction and the next deliberate construction a person can genuinely use, given the available support and context.

More Complex Other →

A person, group, system or environment may make greater complexity available than someone is currently constructing alone. Development depends on whether that difference becomes visible and usable; exposure alone is insufficient. AQ+1 names a conceptual relationship, not a validated numerical dose.

Developmental Environment →

Relationships, language, norms, resources and power shape what can be noticed, chosen and enacted. The environment can expose or suppress complexity; the person’s response can in turn reshape the conditions of the next encounter.

The developmental distinction

From stage location to constructed availability.

CDT does not discard stage development. It changes the emphasis from locating the person abstractly to examining what they can access and construct in a specific context.

A stage-location question

Where is this person developmentally?

This describes a broad developmental altitude or structural tendency, but may not show what is available in the live moment.

A constructed-availability question

What could this person notice, choose and construct here?

This examines awareness, complexity and response as context-sensitive availability rather than a fixed possession.

Measuring development

CDT connects live construction with structured developmental measures.

AQ and TQ describe different aspects of the architecture. The current models and proposed measures require explicit assessment procedures and independent validation; their descriptions alone are not scoring instruments. [1]

Awareness Quotient · AQ →

Available awareness

AQ describes shifts in the awareness from which a person can construct self, other people, context and response. Higher AQ reflects greater visibility of construction and greater availability of deliberate choice; it is not a substitute for TQ’s account of structural complexity.

Thinking Quotient · TQ →

Structural complexity

In the current framework, TQ describes structural cognitive complexity, including the capacity to hold perspectives, systems, principles, contradictions and transformations of frame. It remains distinct from AQ: stage or complexity is not the same as awareness.

The research foundation

The theory emerged through five connected doctoral studies.

The original research examined the thinking and behaviour of postgraduate students through metacognition, constructivism and adult-stage development, initially using Identity Compass profiles. A later study tested the emerging model against a large organisational dataset of more than 8,000 profiles.

[2] As the studies progressed, the question developed from mapping patterns of thinking towards whether Dynamic Intelligence could provide a conceptual measure of self-awareness in the moment. The thesis used TQ as its principal benchmark; that thesis-era construct should not be treated as identical to the later distinction between AQ and TQ.

Associations within the profile systemThe larger organisational study found associations between CI-derived factors and thesis-era TQ. These support initial structure within that dataset, rather than establishing a causal developmental mechanism.
Self-report and profile output divergedParticipants’ self-ratings differed significantly from profile-derived scores across most of the selected CIs. Feedback helped make habituated patterns more visible, but recognition did not demonstrate an ability to change them in the moment.
Contextual construction remained a theoretical interpretationParticipants’ accounts helped inform the interpretation of habitual construction and awareness. The programme did not independently establish stable cross-context prediction or durable developmental change.
TQ emerged as a thesis benchmarkThe research developed a TQ benchmark from Identity Compass-derived CI combinations. This historical use preceded the current separation of structural complexity (TQ) from available awareness (AQ).

Research limitations and continuing work

  • The early studies were exploratory; the second study’s regression predicting TQ was non-significant. Stronger associations appeared in the larger organisational dataset.
  • Several studies used modest or small samples, although the third study analysed more than 8,000 existing profiles.
  • The large dataset provided a broad comparison context, not an independent experimental or randomised control group.
  • Identity Compass-derived predictors and the thesis-era TQ outcome came from the same broader profile system, so this was not independent external validation.
  • The self-report study involved attrition and inconsistent reporting of 54 or 55 completed profiles in parts of the thesis.
  • The interview study involved ten volunteers and was conducted and interpreted by the theory’s creator, leaving a meaningful confirmation risk.
  • The research did not test whether CI-focused interventions cause durable developmental change over time.
How the theory has evolved

The architecture has developed since the thesis.

IACR remains central, while later authorial work differentiates AQ from TQ and elaborates contextual availability. Later formulations should be distinguished from the constructs examined in the original studies.

The early comparative map

Where does CDT fit among existing theories?

CDT was initially positioned in relation to personality, intelligence, emotional intelligence, metacognition and stage development. Its concepts appeared as related territories.

The current architecture

What construction sits beneath those partial descriptions?

CIs describe routes of construction; AQ concerns available awareness; TQ concerns structural complexity; DI describes awareness in the moment. Real-Time Modelling brings this inquiry into the live encounter, with interpretations open to correction.

“The work has moved from naming the ingredients to explaining the construction process.”
Where CDT can be applied

Wherever a human being is required to respond.

These are proposed areas of application, not reports of demonstrated outcomes. Practice remains within the practitioner’s competence and professional scope, with consent and attention to the person’s circumstances.

Coaching

Reveal the construction beneath goals, limitations and repeated patterns.

Leadership

Examine how authority, disagreement and uncertainty are constructed, and which alternative responses become usable.

Education

Move beyond content acquisition towards metacognition and adult development.

Organisations

Examine how leaders and systems construct culture, problems and available action.

Helping practice

Explore cognitive and emotional construction within appropriate professional boundaries. CAIR is the therapeutic/coaching adaptation, distinct from IACR; its effectiveness requires separate evaluation.

Personal development

Increase awareness of familiar constructions and the choices available within them.

What CDT is not

A developmental lens—not another fixed label.

The theory is designed to make construction more visible, not to reduce the person to a category.

  • Not a personality typologyA Thinking Style is a repeated and context-sensitive construction, not an identity.
  • Not a rigid stage ladderDevelopment concerns what awareness and complexity are available in context, not only an abstract location.
  • Not behaviour aloneBehaviour is treated as the visible residue of intention, awareness, meaning and available choice.
  • Not a set of scriptsCDT develops practitioner observation and judgement rather than prescribing one intervention for every person.
Theory & evidence status

A developed theory with an open research programme.

Theoretical account

CDT proposes an account of live construction linking intention, awareness, choice and response with Cognitive Intentions and developmental context. Current AQ/TQ distinctions and the account of the next usable construction draw on later authorial development. [1]

Conceptual coherence and usefulness as a practice lens are distinct from evidence that a specified mechanism causes change.

Empirical boundary

The doctoral programme provides initial quantitative and qualitative support for parts of CDT, with exploratory findings, non-significant results and stronger associations in a larger dataset. [2]

It does not directly validate today’s AQ4–AQ10 map, independently establish IACR or MCO as causal mechanisms, or demonstrate durable intervention effects or therapeutic efficacy. Prospective, independent and longitudinal testing remains necessary.
