Secondary Personality

What have you had to become in order to manage the life you actually had?

WHAT KIND OF IDEA IS THIS? Secondary Personality is a tradition-specific theoretical concept within Biodynamic Psychology. It is not a recognised psychiatric diagnosis or a scientifically validated personality category. That doesn’t mean it cannot be useful — it means we should use it as a way of asking questions, rather than as something we can objectively discover inside another person.

At a glance

The protective organisation a person builds through adaptation to their actual life — the learned patterns, defences and habits that develop around the more spontaneous Primary Personality.

Maybe you learned to be easy, capable, quiet, funny, useful, agreeable, self-sufficient, undemanding, or endlessly competent. Perhaps these ways of being genuinely helped. Perhaps they still help. And perhaps sometimes they now leave less room for something else. That immediately creates a difficult question: when is something a protective psychological pattern, and when is it simply a sensible response to reality? That is where disability makes the concept far more interesting.

You might recognise this

“I make everything look easy because I hate people assuming I can’t cope.” “I say yes to help even when it’s being done in a way I don’t want.” “I become funny when other people get uncomfortable about disability.” “I hate asking for anything because I learned that having needs creates trouble.” “Being extremely competent became the safest way to stop people treating me as incapable.” “Sometimes I genuinely prefer doing things myself — not everything is a defence.”

That last one matters as much as the others. The point is to recognise the pattern and the challenge to the pattern at the same time.

What Boyesen originally meant

Within classical Biodynamic Psychology, Secondary Personality refers to defensive and adaptive patterns understood as obscuring or constraining aspects of Primary Personality. Boyesen’s own language could be strongly evaluative: she associated Secondary Personality with the more “neurotic” and darker elements of character, and with constraints and fears that interfered with contact with the Primary Personality. She also contrasted Primary Personality’s “independent well-being” with a Secondary Personality she saw as more dependent on outside gratification. Later Biodynamic writing describes Secondary Personality similarly, as accumulated defensive organisation, though many contemporary practitioners emphasise that these defences arose for good reasons and may once have been essential.

On this Hub, the concept is held more carefully: protection is not pathology simply because it developed in response to difficulty. Before asking whether a pattern should soften, we need to understand what it does, what produced it, and whether it is still needed. That is a deliberate departure from some of Boyesen’s more evaluative language, not a claim that she wrote it this way herself.

Is Primary good and Secondary bad?

Classical Biodynamic language can make the model sound like Primary equals healthy and authentic, while Secondary equals neurotic and false. That hierarchy is worth questioning. Protection is part of human development. Adaptation is not an error. Sometimes the so-called Secondary Personality contains intelligence, creativity, discipline, humour, social skill and survival knowledge — qualities a person may not need to strip away at all.

Instead, therapy can ask: can I keep the capacity without being trapped in the necessity? Competence without having to prove competence. Kindness without compulsory pleasantness. Independence when chosen, help when wanted. Humour without needing to protect everybody else from discomfort.

A lived scene · fictional teaching example

Daniel has become exceptionally good at proving that he can manage. When somebody offers help, his answer arrives almost automatically: “No, I’m grand.” Sometimes he genuinely is. Other times, accepting help would save him twenty minutes and a considerable amount of energy.

In therapy he talks about how frustrating it is that people assume disability means incapability. His therapist could conclude, “your refusal of help is Secondary Personality.” But that would be too quick. His refusal has history. Being visibly competent has protected him from being patronised, having decisions taken over, being treated as helpless, and having assistance imposed rather than offered. The pattern makes sense.

The therapeutic question is not “how do we remove this defence?” It is “does this still need to happen every time?” Eventually Daniel experiments with accepting help once, from somebody he trusts, in a way he directs. Nothing dramatic happens. He simply notices: “I still feel like me.” That is enough.

Defence, wisdom, or both?

It is tempting to ask whether a pattern is defence or wisdom, as though only one can be true. Often it is both. The child who learned to keep quiet may have been defending themselves wisely. The disabled adult who develops hyper-competence may be reacting both psychologically and rationally to ableism. So the sharper question is not which label fits, but: what has this pattern been wise enough to protect — and does it still need to do that job in exactly the same way?

A process: Notice → Understand → Reality-check → Cost → Protect → Choose

Notice: what seems automatic? Saying yes, refusing help, performing competence, apologising, being pleasant, going quiet, taking care of everybody else.

Understand: what has this pattern done for me? What did it protect? What did it make possible? What would have happened without it? Don’t immediately call it maladaptive.

Reality-check: is the danger or demand still present? This is especially important in disability. People really do patronise. A care relationship really can involve power. An environment really can be inaccessible. Asking really can cost something. The pattern may not simply be “old.”

Cost: even useful protection can have costs. Does it leave less room for rest, anger, asking, pleasure, receiving, vulnerability, choice?

Protect: therapy does not have to remove a strategy that remains necessary. Perhaps the work is making it more conscious, more selective, less costly.

Choose: not “how do I get rid of my Secondary Personality,” but “do I still want this pattern to make the decision every time?”

The body in Secondary Personality

This is Biodynamic psychotherapy, so the concept is not only behavioural. Secondary Personality may be explored through patterns involving breath, tension, movement, voice, expression, distance, bodily impulses, or the felt experience of having to organise yourself around another person. But a bodily pattern does not become psychological simply because it repeats. A tight muscle may involve defence — or spasticity, pain, posture, effort, or several of these together. See Disability Is Not Armour.

The disability question

This is one of the places classical body psychotherapy can misfire most easily on disability. Not every bodily or behavioural pattern in a disabled person’s life is Secondary Personality — adaptive protection layered over a core. Some of it is simply impairment, pacing, or a practical strategy for navigating a genuinely inaccessible world, with nothing to soften. Reading every pattern as protective adaptation risks pathologising things that are actually just facts about a body or a life.

Genuine Secondary Personality, in a disability context, often looks like this: hyper-competence built specifically to counter others’ assumptions of incapability, pleasantness that manages other people’s discomfort, or compliance that protects a needed care relationship. Those are real, examinable adaptations.

Using a wheelchair, pacing activity, communicating differently or needing rest may be practical, bodily or access adaptations. Their adaptive nature does not make them Secondary Personality. The important distinction is between adapting to reality and psychologically organising oneself around what one has learned must be hidden, performed, prevented or managed. And for assistive technology especially: a wheelchair is not simply “the body’s shape.” It may be experienced as equipment, as an extension of embodiment, as part of body-world interaction, or differently at different times — none of that experience is settled by the theory in advance.

Dependence is not Secondary Personality

Boyesen explicitly contrasted Primary Personality’s “independent well-being” with a Secondary Personality more dependent on others and external gratification. That is precisely where a disability-informed reading has to intervene. Physical dependence does not tell us whether somebody is psychologically defended. A person may depend on another human being to transfer, dress, eat, communicate, travel or regulate physically. That is not evidence of psychological immaturity. Human beings generally depend on relationships, communities, infrastructure, care and technology.

A more useful question is: can I remain psychologically authored while depending on other people? — rather than: can I become independent enough to prove psychological health?

Who gets to decide that something is a defence?

A therapist may notice a repetitive pattern. They may offer a hypothesis. But they cannot know from the outside that someone’s quietness, independence, dependency, politeness, stillness, fatigue or reluctance represents Secondary Personality. The person may say, “no, that’s not protection, that’s actually what I want.” That answer needs to be possible.

If a theory cannot survive the client telling us it is wrong, the theory has become too powerful.

Where this concept can help

Secondary Personality may be useful when exploring compulsory competence, people-pleasing, masking, difficulty asking for help, chronic apologising, performing gratitude, managing other people’s discomfort, being unable to rest, hiding anger, automatic compliance, or roles that once protected someone but now leave little choice.

Where it should stop

Do not use Secondary Personality to explain, automatically: a wheelchair; fatigue; rest; slow movement; limited movement; speech differences; pain behaviour; need for assistance; sensory regulation; avoiding inaccessible places; medical caution; or somebody simply preferring to live differently from the therapist.

Do not call reality a defence because it makes the theory uncomfortable.

What this might look like in therapy

A therapist might notice a client apologise before every request. Rather than stating “that’s your Secondary Personality protecting you,” they might ask: “I notice you often apologise before asking for something. Is that something you’re aware of?” The client might say yes, and explore where it came from. They might say no, and that it’s simply politeness they were raised with. Both are legitimate directions. The concept should open the question, not settle it in advance.

BEFORE I CALL SOMETHING SECONDARY PERSONALITY… What exactly have I observed? What am I inferring? Could this be physical, neurological, relational or environmental? What has this pattern protected? Is the threat still real? Does the client experience this as constraining? Would changing it actually improve their life — or merely make them look more psychologically “healthy” to me?

Evidence and status

Secondary Personality is a central theoretical construct within Biodynamic Psychology, associated with Gerda Boyesen’s distinction between Primary and Secondary Personality. Boyesen described Secondary Personality in strongly psychodynamic and Reichian terms involving defence, inhibition, loss of contact with life-force, and diminished self-regulation. It should not be presented as a validated personality category or diagnosis. Its usefulness here is as a clinical lens for exploring protection, adaptation and reduced choice.

The disability-informed interpretation on this page — particularly the distinctions among physical reality, practical adaptation and psychological defensive organisation — is a critical reconstruction rather than a claim that Boyesen herself developed a disability model.

Protection does not become pathology simply because it is protective. Adaptation is not failure. The aim is not to strip away a Secondary Personality until a supposedly purer person appears underneath. It is to create enough safety, understanding and choice that protection no longer has to make every decision.

A question worth carrying

What has this pattern been wise enough to protect — and does it still need to do that job in exactly the same way?

From the inside

Secondary personality, or survival?

People with Down syndrome may have learned to be cheerful because that is what was rewarded. People with sickle cell may have learned to be guarded after being doubted in A&E. People with long-term mental health conditions may have learned to hide how they feel to avoid admission.

These can look like a secondary personality covering the real self. They are often reasonable survival strategies.
