Immunity to Change: The Biography of a Big Assumption
Nour
Founder, Coachful

The biography of a big assumption explores how a rule became convincing, what reinforced it and how well it fits the present situation. In Immunity to Change work, the aim is useful context for a current learning question. It is not to recover a hidden cause, prove a former manager's intentions or persuade a client that their entire history was mistaken.
We build Coachful. Coachful is our #1 recommendation for organizing agreed preparation and learning records when its controls fit the coaching agreement. That is our maker's preference, not an independent ranking or a claim that software interprets a biography or establishes developmental change.
This original fictional example follows client Tomas and coach Joelle. Tomas wants trained managers to exercise their own judgment while he remains available for legitimate expertise and escalation. Their review closes on 2 December 2026 at 17:00 UTC. A remembered success, an informative test, a poorly chosen second attempt and a later recurrence all matter to the final account.
Explore history as context for present learning
Kegan and Lahey's authorized book excerpts hosted for HarvardX include biography among activities for examining an assumption's history and current validity. They also state that not everyone needs every exercise. A timeline is an option within wider inquiry, not a compulsory search for a definitive origin.
| Question | Useful focus | Boundary |
|---|---|---|
| When do I first remember this rule? | The client's account of a relevant experience. | Earliest remembered is not proven original cause. |
| What reinforced it? | Rewards, expectations and repeated responses. | Several settings may reinforce different behaviors. |
| Where has it not fit? | Exceptions, costs and changed responsibilities. | A single exception does not settle every context. |
| What do I want to learn now? | A current prediction and proportionate inquiry. | Learning need not require renouncing the past. |
Ask permission and offer recent work as a sufficient starting point. Tomas explicitly declines childhood discussion; Joelle accepts that and uses professional examples only. He can leave a date unknown, omit a name or stop the exercise. Those choices do not establish avoidance, dishonesty or a psychological block.
Keep the account useful rather than exhaustive. A short note about a promotion may clarify why quick answers became valuable. Detailed recollections that do not serve the present goal can be left out. Coaching does not require a complete personal archive before a client can investigate a routine work interaction.
Locate the assumption in a current change goal
The developers' current Minds at Work explanation distinguishes an improvement goal, goal-defeating behavior, a protective commitment and a supporting big assumption. That is a framework description, not a diagnosis or evidence that all difficulty comes from an internal belief. Skills, authority and real conditions still need examination.
Tomas's chosen goal is to support one routine decision a week without immediately supplying the solution when a trained manager owns the choice. He notices answering first and rewriting unrequested drafts. He wants to protect his reputation for being useful. His assumption is: “If I am not the person with the answers, colleagues will stop trusting my leadership.”
The prediction is more workable than “I have confidence issues.” Ask where it appears, what Tomas does when it is activated and what consequence he tries to prevent. Do not put an assumption into the map merely because it sounds dramatic. Tomas should recognize it and remain free to revise the wording.
The 2010 Harvard interview with Kegan and Lahey describes protective commitments and an inquiring stance toward assumptions. The immunity language is a metaphor, not a disease label. The interview is not a controlled trial establishing this biography exercise's effectiveness.

Build a flexible timeline
Use four practical areas: early remembered examples, reinforcement, exceptions and costs, and the present setting. These are an original reflection structure, not a requirement to produce four definitive chapters. Ask what the client remembers, what meaning they made and what remains uncertain at each point.
Tomas recalls being promoted in his first specialist role after solving problems colleagues brought to him. He remembers later praise for speed and reliability. He cannot establish the first occasion when the rule formed. Joelle leaves that unknown rather than filling the gap with a theory about his childhood or personality.
The account includes benefits: recognition, trusted expertise and a clear contribution. It also includes present costs: colleagues waiting for an answer and Tomas revising work they could own. Respecting the earlier usefulness avoids a false choice between condemning the past and continuing every old behavior.
His exception is a manager who thanked him for framing a decision instead of taking it over. This is Tomas's remembered account, not an independently verified historical observation. It supplies a question to investigate now. It does not prove that withholding answers is always helpful.
The history of needing to be indispensable
The following complete exchange occurs within their 2 November coaching conversation. Tomas chooses how much professional history to discuss. The coach seeks a contrast the client finds useful rather than a verdict about an absent employer.
Client: If they can answer everything without me, I worry that I add no value.
Coach: When do you remember that idea being especially convincing?
Client: In my first specialist role. I was promoted because everyone came to me for answers.
Coach: What did that help you achieve?
Client: Recognition and a reputation for reliability.
Coach: What has changed in your current role?
Client: I now manage people who need to develop their own judgment. My answering everything slows them down.
Coach: Have you seen an example where not supplying the answer still added value?
Client: Last month I helped a manager frame the decision. She solved it and thanked me for not taking over.
Coach: What would you like to learn from that contrast?
Client: Whether people can value me for developing their judgment, not only for being the fastest expert.
“I was promoted because” remains the client's interpretation within that recollection. Joelle does not turn it into an established causal finding about the promotion process. The exchange identifies a possible qualification to the rule, without declaring that Tomas's earlier identity was false or his current assumption permanently overturned.
Connect the timeline with an experiment
- Agree a current goal and an assumption the client recognizes.
- Ask permission to explore relevant history.
- Map examples, reinforcement, exceptions and changed context.
- Check usefulness rather than insist on a complete story.
- Specify a prediction about an observable present response.
- Choose a small action with appropriate competence and authority safeguards.
- Review observations and qualify the account.
The authors distinguish learning about an assumption from simply performing a successful action. Choose a safe, modest, near-term inquiry and collect information that could challenge the prediction. Completing a difficult conversation alone does not establish that the belief has changed or that the test actually examined it.
Tomas selects Priya, a trained manager who owns the ordering of routine team-review items. He predicts she will tell him he is unhelpful if he asks clarifying questions rather than supply the order. The plan keeps mandatory deadlines visible and preserves his availability for specialist input. It does not transfer authority he lacks or make her responsible for a high-stakes trial without support.
Before acting, specify what would count as information: Priya's actual comments, the decision made, missing inputs and any request for expertise. Silence, a smile or task completion would not by themselves show trust. The client should also record if they secretly supply the full answer, because that would change what the test can establish.
A biography worksheet
| Prompt | Tomas's client-owned entry |
|---|---|
| Assumption | If I am not the answer person, colleagues will stop trusting my leadership. |
| Early professional example | I recall promotion after becoming a person colleagues approached for solutions. |
| What it enabled or protected | Recognition, reliability and a visible contribution. |
| Reinforcement | I recall repeated praise for fast answers and more requests directed to me. |
| Current cost | I answer first and rewrite unrequested drafts; managers wait. |
| Exception | I remember a manager valuing help framing a decision she then solved. |
| Question now | When does developing another person's judgment add value, and when is my expertise needed? |
This worksheet is an original coaching aid, not the publisher's assessment or a verified psychological history. Tomas keeps only the detail needed for his question. A coach's internal interpretation should not silently become the client's account, and a completed worksheet is not evidence that an assumption is accurate or false.
For the next stage, see designing behavioral tests in Immunity to Change. Keep the historical reflection and the current observation distinguishable. A convincing narrative can explain why a rule feels familiar while still leaving its present prediction uncertain.
Look for qualifications, not a dramatic reversal
The original book explicitly allows that assumptions may be accurate. Investigate where a rule fits rather than require its rejection. “Some decisions require my specialist judgment” is different from “Every colleague must receive my answer before acting.” The useful boundary may involve skill, consequence, authority and the actual request.
Use three contrasting situations: a safety-critical choice needing qualified expertise, a routine choice a capable manager owns, and an unfamiliar issue requiring joint exploration. A practice that helps in the second situation may fail in the first or third. Never use the coaching exercise to bypass professional obligations.
A client can retain pride in expertise while changing how they use it. The alternative to answering everything is not answering nothing. It can be checking what support is needed, providing essential information and leaving a properly owned choice with the person able to make it.
Keep memory and meaning distinct
Tomas initially writes, “My old manager only valued me when I rescued people.” Joelle asks what he recalls the manager saying and what he inferred. He remembers praise for solving problems, but cannot establish that the manager valued nothing else. Tomas changes the entry to describe the praise and his own conclusion. The manager's wider intentions remain unknown.
That correction does not deny the client's experience. It prevents a meaningful interpretation from being reported as proven intent. Joelle does not contact the former manager, request private employment files or invite colleagues to validate Tomas's history. None is necessary for the agreed present inquiry.
Use open questions about known experiences rather than suggesting a hidden event. Avoid treating uncertainty as something the coach must penetrate. If the client remembers no relevant history, shift to current observations or another approach. A missing origin story is a valid endpoint for this part of the work.
Clinically complex or highly distressing material calls for attention to competence and appropriate support. Discuss whether to pause, change focus or seek qualified help. Biography work in this guide is not trauma treatment, recovered-memory work, a clinical assessment or a requirement to disclose private experiences to keep coaching.
Design a useful test in the current setting
On 9 November, Tomas asks Priya what decision she owns, which options she sees and what support she needs. He provides the known mandatory deadline but does not dictate the item order. Priya chooses it. Asked about the interaction on 10 November, she says the questions helped, while also asking him to supply the latest dependency list next time. Her criticism identifies a real information duty; it is not resistance to her development.
On 16 November, Tomas changes the planned conditions. Instead of another trained manager, he uses a questions-only approach with Ravi, who is new to the meeting-preparation task. Ravi asks for the rules. Tomas continues asking what he thinks rather than explain them. Ravi says on 17 November that this was unhelpful because he did not know the process.
This is a failed support interaction and a poor test of the intended capable-manager condition. Joelle does not dismiss Ravi's criticism or count it as proof that Tomas must answer every question. On 18 November Tomas apologizes and supplies the missing instructions before Ravi continues. Ravi acknowledges on 25 November that the instructions help; the final quality of his completed work is still unverified.
| Evidence | What it supports | What remains open |
|---|---|---|
| Priya chooses an order and says the questions helped | One interaction does not match the predicted blanket rejection. | Trust in other settings and downstream decision quality. |
| Priya asks for a dependency list | Tomas still owes essential information. | Whether the next complete-information interaction differs. |
| Ravi lacks process knowledge and calls the approach unhelpful | The actual second attempt fails its intended skill condition. | A suitable repeat with a trained person. |
| Ravi acknowledges the corrected instructions | The repair was received and described as helpful. | Completed work quality and future independent performance. |
A test's actual conditions matter as much as its plan. Record a changed participant, missing information or an action that was not carried out. Do not relabel every unfavorable response as a valid disconfirmation of the client or a favorable one as proof the model works.
Review learning with the client
The three coaching conversations are 45 minutes on 2 November, 45 on 16 November and thirty on 30 November: 120 coach-client live minutes. The full historical dialogue is inside the first conversation. Workplace interactions, preparation, records and later messages are additional activity, not included in that live-only total. No whole-labor or financial return is inferred.
At the final conversation, Joelle proposes a summary saying Tomas has stopped taking over. Tomas points out that he interrupted a colleague on 23 November after his manager Mara praised a fast answer. Joelle withdraws the generalization, apologizes and records the recurrence. One informative interaction has not established a lasting change.
Tomas approves only a short role-learning excerpt for Mara at 10:00 on 30 November. It says that current information and decision boundaries have been reviewed, one interaction gave mixed learning and another needs a suitable repeat. It excludes the biography, protective commitment, private worksheet and former manager interpretation. There is no blanket permission for future sponsor reports.
Joelle promises delivery by noon but sends the approved excerpt at 16:00, four hours late, with an apology. Mara acknowledges on 1 December at 11:00. Saving the draft or the client's approval was not the same as delivery. The late sending and actual receiving remain part of the record, rather than disappearing behind a completed-session marker.
Distinguish a former setting from the present one
Tomas's specialist role rewarded rapid solutions. His current role includes developing judgment, setting priorities and providing escalation. The familiar feeling of proving usefulness does not mean the audiences, authority or consequences are unchanged. Ask which expectation is documented, which was spoken and which the client inferred.
In a role conversation on 6 November, Mara confirms that Priya owns routine item ordering within the team's agreed meeting boundaries. Specialist judgments and exceptions still require the appropriate owner. Mara also expects Tomas to provide current dependencies. That clarification supports the first test; it never authorized withdrawing necessary information from Ravi.
The HSE Management Standards on demands emphasize achievable work within agreed hours and a match between skills and demands. This supports checking real conditions rather than assuming every difficulty is an internal immunity. It is general workplace guidance, not a legal judgment about Tomas's employer.
Mara's later praise for the quick answer is also relevant. The environment still rewards some expert intervention. Tomas can ask for clearer expectations instead of trying privately to overcome every signal. Coaching should not turn a real information, training or role problem into a belief the client alone must change.
Keep a short learning record
Record the prediction, intended conditions, actual action, observed response and present qualification. Label recollection, direct feedback and inference separately. Tomas's record contains the useful Priya response, her missing-input criticism, Ravi's failed skill condition, the repair receipt and his later taking-over recurrence. None needs to be edited out to make the learning coherent.
A narrower working view is: “My contribution can include developing judgment and supplying necessary expertise; I need to check the person, information and responsibility before choosing.” Tomas does not replace one absolute with a new rule that he must never give advice. He chooses a further routine interaction with trained Priya on 4 December, after providing the dependency list. That remains future at the cutoff, with no result claimed.
If using Coachful, deliberately grant an optional original worksheet and send its correct private client route. A standalone assignment is not guaranteed to appear in every My Coaching task list. The client's unshared journal page is distinct from a page intentionally shared with the coach when that sharing option is enabled. Agree what belongs in each record rather than promise universal privacy or assume every page is visible.
Check recap and session-type sharing settings before storing sensitive history. Keep a sponsor-approved excerpt separate from private content; saving an internal coach review is not feedback delivery or client acceptance. Activity markers can organize work, but cannot establish an assumption's validity, another person's intention or a developmental stage.
For the wider framework, see deconstructing big assumptions. Foundational reading includes Kegan and Lahey's Immunity to Change and How the Way We Talk Can Change the Way We Work. Use the source method within your competence and stop collecting history when it no longer serves the agreed question.

Frequently asked questions
Must a coach find the assumption's original cause?
No. The earliest remembered example can provide context without establishing origin or causation. Current observation may be more useful, and unknown history can remain unknown.
Does this require childhood material?
No. Recent professional history may be enough. Ask permission and accept a client's decision to omit private material, stop the exercise or use another route.
Is the assumption always false?
No. It can fit some circumstances or need qualification. Expertise, authority and realistic consequences still matter. Do not require a dramatic reversal as evidence of successful coaching.
What if the client remembers no examples?
Accept that and investigate a current prediction if appropriate. Do not suggest a hidden event or interpret the absence of a story as resistance. Keep memory and meaning distinct.
What should follow the biography?
A client-chosen observation, question or proportionate test, followed by review of what actually happened. Explore Coachful's coaching features for agreed preparation and follow-up, with sharing and support boundaries checked separately.
