In the 1980s, a psychophysicist named Howard Moskowitz made 45 versions of Prego spaghetti sauce, fed them to thousands of people, and measured precisely how much each person liked each one. He was looking for the single perfect sauce. He did not find it. What he found instead reshaped the food industry — and, read correctly, it dismantles the central assumption of the entire executive coaching profession.
The data did not converge on one ideal recipe. It split into clusters. Some people wanted the sauce plain, some spicy, and a large group nobody had known existed wanted it extra chunky. Moskowitz’s famous formulation, from his earlier soft-drink work, was that a company had been looking for the perfect Pepsi when it should have been looking for the perfect Pepsis. Plural. There is no perfect pickle. There are only perfect pickles.
Executive coaching has spent thirty years making exactly the mistake Moskowitz diagnosed. And it has a second problem hidden inside the same discovery — one that goes to the heart of why so much coaching feels transformative and produces nothing.
The wrong search: hunting for the one right method
The coaching field is organized around competing schools of thought, each with adherents who believe theirs is the right one. The major schools are real, distinct, and genuinely different in their underlying theory of how a human being changes.
The GROW model (Goal, Reality, Options, Will), developed by Sir John Whitmore, is structured and goal-directed. It anchors each session to a clear desired outcome, examines current reality, generates options, and commits to next steps. It is grounded in behavioral science and built for performance.
Cognitive-behavioral coaching (CBC) applies the thoughts-emotions-behaviors framework of CBT: identify limiting beliefs and cognitive distortions, restructure them, and build more adaptive thinking patterns through structured exercises. Evidence-based, self-regulation-focused.
Positive psychology coaching, rooted in Martin Seligman’s work and operationalized by researchers like Anthony Grant, focuses on identifying and building strengths and a positive vision rather than fixing deficits.
Ontological coaching (Fernando Flores, Julio Olalla, James Flaherty) works on the client’s way of being — the dynamic interplay of language, emotion, and physiology. It is transformative and developmental, concerned with who the person is being, not merely what they are doing.
Co-active coaching and the Inner Game (Timothy Gallwey, Laura Whitworth, and again Whitmore) treat the client as naturally creative, resourceful, and whole, with the coach as a thinking partner rather than an expert dispensing answers.
The academic literature frames the deepest split cleanly: one school holds that the purpose of coaching is to change behavior through a goal-directed approach; the counterview holds that coaching is a meaning-making process, a shared journey that may or may not result in behavior change. These rest on genuinely different ontologies and epistemologies — different theories of what reality is and how we come to know it.
The field keeps asking which school is right. That is the perfect-Pepsi question. And it has the same answer Moskowitz gave: wrong question.
The portfolio insight: leaders cluster, and each cluster has a bliss point
The Moskowitz correction is that there is no single perfect coaching method because leaders, like sauce preferences, cluster. Different leaders have fundamentally different bliss points — different approaches at which coaching actually moves them — and the schools are not competitors for one throne. They are the varieties in a product line, each tuned to a different cluster.
A results-driven operator under time pressure has a bliss point at GROW: structured, goal-anchored, action-committed. A leader whose problem is a recurring self-limiting pattern has a bliss point at CBC: identify the distortion, restructure it. A leader who has plateaued despite competence has a bliss point at ontological or co-active work: the issue is not a missing skill but a way of being. A leader recovering from burnout or leading through fear has a bliss point at positive psychology: rebuild from strengths, not from deficit.
The extra-chunky finding matters most here. Moskowitz’s real money came from the cluster nobody in the industry had known existed. In coaching, the equivalent is the leader who has cycled through three conventional approaches and stalled in each — not because they are uncoachable, but because their cluster was never served. The coach who assumes their single favored school fits every client is the pre-Moskowitz food company insisting on one perfect sauce, leaving the chunky cluster — often the highest-value one — completely unserved.
The professional move is not to pick a school and defend it. It is to build a portfolio and diagnose the cluster. The best executive coaches already work this way — blending directive GROW-style prompts here and nondirective ontological inquiry there, selecting the model that fits the client’s context, time horizon, and desired outcome. Frameworks as tools, not rules. That is Moskowitz’s product line, applied to human development.
The second trap: the bliss point is not the change point
Here the bliss point turns from insight to warning, and this is the part the coaching industry rarely says out loud.
Moskowitz’s bliss point is the concentration at which a food is liked the most. But recall what the food engineers did with it. They did not stop at making food people liked. They built food that people could not stop eating — engineering vanishing caloric density, beating the body’s fullness clock, exploiting the absence of an off switch. The bliss point was the entry; addiction was the product. The food that hits the bliss point most reliably is frequently the food that nourishes least.
Executive coaching has its own bliss point, and its own vanishing caloric density. A coaching engagement can be engineered — deliberately or not — to feel extraordinary. The deep rapport, the flattering attention, the affirming reframes, the sensation of profound insight in the room. The executive leaves each session feeling seen, energized, validated. It feels like the richest developmental experience on earth. And like a food dissolving before the brain registers it, the insight can vanish before it becomes changed behavior. The session felt like a thousand calories of growth. The body of the person’s actual conduct records nothing.
This is the coaching equivalent of the tolerance study, in which teenagers who consumed the most ice cream showed the weakest reward response and needed more to feel anything. An executive can become dependent on the bliss of being coached — the recurring hit of affirmation and insight — while the developmental return steadily shrinks. They chase the feeling of growth, and the feeling gets emptier, and they book more sessions. The engagement is thriving. The leader is not developing. Coach and client are both satisfied, which is precisely the problem.
The bliss point of coaching — the approach that feels best — is not reliably the point where coaching works. Sometimes they align. Often they do not. The approaches that produce durable change are frequently the ones that feel worst in the room: the confronting question, the withdrawn scaffold, the refusal to affirm, the demand for evidence of changed behavior between sessions. That is coaching’s whole food. It is slower, harder to swallow, and far less immediately pleasurable than the engineered bliss.
How we go around the problem
The two halves of the bliss point resolve into a single discipline, and it is worth stating plainly because it is how the trap is actually escaped.
First, diagnose the cluster before selecting the school. Stop asking which method is best. Start measuring which method fits this leader, this problem, this moment. Run coaching as a product line, not a single sauce. The Moskowitz move is to let the data about the individual — not the coach’s allegiance to a school — determine the approach.
Second, separate the bliss metric from the change metric, and govern by the second. Satisfaction — how good the coaching feels — is the bliss point, and it is dangerously easy to optimize. Changed behavior, observed by others between sessions, is the nourishment, and it is what actually matters. Moskowitz’s foundational insight applies with full force: if you ask people whether the coaching is working, they will tell you it feels great — and that is not the same as it working. Stop asking how the coaching feels. Start measuring what the leader now does differently that others can see.
That is the whole method for going around the problem. Match the school to the cluster. Then refuse to let the bliss of the engagement stand in for the evidence of change.
Mapped to the Mutation Readiness framework
This maps directly onto three dimensions of the Mutation Readiness diagnostic — the operational instrument of the Mutation transformation practice we run for enterprise leaders.
Signal Sensitivity — the entire Moskowitz method is Signal Sensitivity: distrust the stated signal (what people say they want, how good it feels) and read the measured one (which cluster a leader is actually in, whether behavior actually changed). A coaching practice with high Signal Sensitivity diagnoses the cluster and tracks real behavioral change. One with low Signal Sensitivity picks a favorite school and grades itself on how good the sessions felt.
Ethical Guardrails — framed in the diagnostic as containment-as-velocity. The coaching bliss-point trap is a guardrails failure: an engagement optimized for the feeling of growth rather than growth itself, generating dependency the way engineered food generates craving. The guardrail is the discipline of measuring changed behavior and being willing to end or redirect an engagement that feels wonderful and delivers nothing. Velocity that nourishes, not velocity that merely satisfies.
Structural Flexibility — the portfolio insight is Structural Flexibility applied to development. A coach or a leadership-development function that can fluidly move between GROW, CBC, positive psychology, ontological, and co-active approaches as the cluster demands is structurally flexible. One locked to a single school cannot reshape to fit the leader in front of it, and will keep serving plain sauce to the chunky cluster.
The signals your organization is missing right now
In your own leadership-development function, the master signal is the gap between coaching satisfaction and coaching outcome. High satisfaction scores paired with unchanged 360 feedback is the bliss-point trap in its purest form — the engagement is delicious and nutritionally empty.
Look for the specific tells. Are your coaches matched to leaders by cluster and need, or by whoever was available and whatever school they practice? Do your highest-satisfaction engagements actually produce the largest observed behavior change, or the smallest? Which leaders have been in coaching longest with the least visible development — the dependency signal? Each is a weak signal that your development function is optimizing the bliss point instead of the change point.
Three practical questions
One: are you selecting a coaching school, or diagnosing a leader’s cluster? If your development function has a house method that every leader receives, you are the pre-Moskowitz food company insisting on one perfect sauce. Match the school to the leader, and make sure your bench covers enough clusters — including the chunky one nobody else is serving.
Two: are you measuring how the coaching feels, or what the leader now does differently? Satisfaction is the bliss point and it lies. Observed behavioral change is the nourishment. If your only coaching metric is a satisfaction survey, you are grading the sugar content and ignoring whether anyone was fed.
Three: which of your coaching engagements are delicious and empty? Find the ones with high satisfaction and low behavioral change. Those are not successes with a measurement gap. They are the vanishing caloric density of executive development — and they are the first place to intervene.
The closing thought
Howard Moskowitz gave two gifts, and coaching has taken neither. The first is that there is no perfect method — only perfect methods, one per cluster — and the professional’s job is to diagnose the person and match the approach, not to evangelize a school. The second, darker gift is that the point where something feels best is not the point where it does the most good, and a sophisticated practice can engineer the feeling while starving the substance.
Executive coaching, at its best, is whole food: matched to the individual, sometimes uncomfortable, measured by what changes in the leader’s conduct rather than by how the session felt. At its worst it is engineered snack food: one house method applied to everyone, optimized for the bliss of the room, generating satisfied dependency and no development. The difference between the two is not the school on the coach’s business card. It is whether the practice diagnoses the cluster and measures the change — or serves the bliss point and calls it growth.
The world has changed. The leaders who notice will be the ones the next decade is built around.
