Almost a year ago, we launched a study on the Adaptation Coefficient: an indicator designed as a complement to the Intelligence Quotient and the Emotional Quotient, measuring not what we know or what we feel, but our capacity to effectively modify our behaviors, cognitions and emotions in the face of change, while maintaining our performance and well-being. This article opens a series presenting its first conclusions. It sets the frame: where this hypothesis came from, how we tested it, and what fifteen interviews with business leaders brought to light.
A hypothesis born of a gap
The idea of the Adaptation Coefficient started with a gap. We have solid tools to measure intelligence: IQ assesses our capacity to reason, learn and solve problems. Since the work popularized in the 1990s, we also have an Emotional Quotient that assesses our relational intelligence. But neither indicator really answers the question that matters today: are we actually capable of changing when the world around us changes faster than we do?
This question is not theoretical. Economic crises keep recurring, the ecological transition forces us to reconsider entire models, technology disrupts professions within a few years, and geopolitical tensions reshuffle value chains we once thought stable. In this context, the capacity to adapt, both for individuals and for the organizations they lead, becomes a vital skill rather than a mere asset.
As soon as this hypothesis emerged, one question arose immediately: did the concept already exist, under another name, in an established field of research? A review of the literature in psychology, sociology, ecology and economics confirmed that no precise occurrence of the term “Adaptation Coefficient” existed to describe this capacity for personal and organizational adaptability. Related fields do exist: Ployhart and Bliese’s Individual Adaptability Theory (I-ADAPT), adaptive performance in work psychology, adaptive expertise, psychological resilience, and adaptive capacity of systems in climate science and public policy. This body of work informed the research, but none of it offered a unified, measurable framework applicable to both an individual and the organization they lead. The ground was clear.
Four dimensions, one score
The Adaptation Coefficient rests on four dimensions, each weighted differently in the final score:
Cognitive dimension (30%): mental flexibility and learning capacity. Considering several perspectives at once, quickly acquiring new skills, generating creative solutions, being aware of one’s own adaptation mechanisms.
Behavioral dimension (30%): agility in action. Dropping a habit that has become obsolete, testing new approaches, adjusting one’s behavior to context, persevering despite obstacles.
Emotional dimension (20%): resilience and regulation. Managing stress linked to change, tolerating ambiguity, bouncing back after failure, maintaining realistic optimism.
Social dimension (20%): relational adaptation. Adjusting one’s interactions according to context, collaborating in varied configurations, adapting one’s communication to the audience, understanding others’ changing needs.
These four dimensions produce a raw score out of 100. But a raw score is not enough to account for the quality of an interview or the coherence of a discourse, which is why a confidence factor weights it, built from five cross-cutting meta-indicators: congruence (the overall coherence of the discourse), specificity (the richness of concrete examples versus generalities), humility (genuine acknowledgment of limits and failures), reflexivity (the capacity to analyze one’s own processes) and authenticity (sincerity as opposed to a polished facade). The final score, the AC, results from crossing these two elements: a raw score on the four dimensions, corrected by a confidence factor that penalizes hollow discourse and rewards proof by example.
A method rather than an intuition
However solid a hypothesis may be, it is only worth something once tested against reality. So this research did not stop at theory: it was built interview after interview, with leaders of companies of very different sizes and sectors, recorded as a podcast as part of Le Quotient A. Each interview follows a structure of five sequences of about one hour each: the journey and triggers of adaptation, day-to-day adaptation broken down across the four dimensions of the AC, how a high-performing collective functions, doubts and blind spots, and finally projection and transmission. This last sequence, deliberately placed at the end of the interview once trust has been established, seeks authenticity over performance: leaders are asked what keeps them up at night, not what they would like to be remembered for.
Each interview is then run through a detailed evaluation grid, the Full AC Grid, comprising 37 indicators spread across the five sequences, each scored from 0 to 4 against precise, observable criteria. This granularity is deliberate: it forces every score to be documented with quotes and concrete examples drawn from the interview, rather than a general impression. The central methodological rule of this research is the following: the analysis must be balanced, not indulgent. A score of 0 on an indicator does not necessarily mean the leader fails on that point, but that the interview did not yield sufficient evidence, a distinction we return to in the limitations below.
Finally, a data governance principle was set from the start and has never been revisited since: when a score calculated from the grid diverges from a reference score recorded in the corpus tracking table, the latter prevails. Discrepancies are documented and flagged explicitly rather than silently corrected, since they are themselves a useful signal about the robustness of the method.
A corpus of fifteen profiles
At this stage of the research, the corpus brings together fifteen leaders, with AC scores ranging from 36 to 66 out of 100. This spread is not accidental: it allows comparison of profiles across different adaptation zones, from moderate to high, and identifying what genuinely distinguishes them, rather than merely studying already-celebrated success stories. Research that only interviewed already very high-AC profiles would produce a flattering but not very useful narrative: we learn more from tipping points, glass ceilings and intermediate configurations than from the summits alone.
The organizations led by these individuals cover a wide range of sizes, from a handful of employees to several tens of thousands, and equally diverse sectors: consulting, industry, digital, trading, chambers of commerce, multi-generational family businesses. This diversity is deliberate: the working hypothesis was that invariants of adaptability, if they exist, should appear independently of an organization’s sector or size. The first cross-analyses, notably on socio-demographic variables, partly confirm this hypothesis: among the factors tested (age, gender, company size, sector of activity), only age shows, at this stage, a notable correlation with the AC score. Neither the size of the organization nor its sector appears predictive so far. This is still a provisional result, to be confirmed on a larger corpus, but it supports a central hypothesis of this research: adaptability is above all a skill, not a mechanical consequence of the context one operates in.
What emerged: fifteen invariants
This is the core of the work accomplished so far. By methodically cross-referencing the fifteen profiles, recurring patterns emerged, robust enough to be called invariants: mechanisms that, in different forms depending on the person and the organization, seem to structure the capacity to adapt. Eight of these invariants concern the individual, seven concern the organization they lead. Each will be the subject of a dedicated article in this series; here is a summary overview to set the frame.
On the individual side
The capacity for active unlearning, which requires genuinely dropping a conviction rather than simply adding a skill on top of it.
Conscious segmentation between a stable core and a flexible periphery, what never moves protecting what must move constantly, an invariant that connects to our reflections on the individual within the collective.
A structured external support ecosystem, because no one adapts alone, and what matters is an outside perspective that challenges, not merely one that reassures.
A productive relationship with doubt, which becomes a tool for vigilance once it is framed by a principle of action rather than a paralyzing state.
The transformation of negative emotions into energy for action: anger, fear or frustration reprocessed into movement rather than simply endured.
Assumed vulnerability, particularly the kind that touches the leader’s model or convictions, more significant than vulnerability limited to execution.
An active posture of transmission: seeking to pass on what has been learned through several real channels rather than through declared intention alone.
Adaptation as a “third way” between resistance and submission, a step sideways that refuses both to passively endure change and to dissolve into it without discernment.
On the organizational side
A culture embodied through living rituals, not merely declared in speeches.
Explicit separation of timeframes between the long-term vision and short-term execution.
Few but genuinely enforced non-negotiables, with visible consequences in case of transgression.
An institutionalized architecture of contradiction, which actively provokes disagreement rather than merely tolerating it.
Treating error as a collective learning system, rather than as grounds for individual sanction.
Genuine delegation, with an authentic transfer of decision-making power and not just execution tasks, a principle also found in distributed governance models.
Collective intelligence that surpasses the leader, to the point of producing decisions that surprise them.
A three-level hierarchy
One finding stood out through the cross-analysis: not all these invariants carry the same weight, and they do not appear at the same stage of adaptability development. A three-level hierarchy emerged.
Necessary conditions are those found even among moderate-AC profiles: some segmentation, even implicit, between a core and a periphery; some form of unlearning, even partial or forced; a minimal openness to contradiction, even passive; an acceptance of incompleteness; embodied non-negotiables, even without exhaustive documentation. Their absence seems to cap the AC around 40 out of 100, regardless of the quality of the discourse on other dimensions.
Differentiating conditions are partially present among intermediate profiles and allow progression into the 50-to-65 zone: a genuinely structured, not merely dense, support ecosystem; resilience actively built rather than endured; vulnerability that touches the model and not just execution; a ritualized rather than merely declared culture; transmission through several effective channels.
Conditions of excellence, finally, are fully present only among the highest-AC profiles in the corpus: collective intelligence institutionalized to the point of producing decisions that genuinely surprise the leader; an architecture of contradiction that goes as far as questioning the leader themselves; genuine delegation accompanied by identity work; spontaneous reflexivity on one’s own adaptation mechanisms; and daily emotional regulation distinct from mere resilience in the face of exceptional events.
This hierarchy echoes our reflections on robustness and adaptation: necessary conditions lay the robust foundation on which differentiating conditions, and then conditions of excellence, build a chosen rather than endured adaptability.
The limitations we acknowledge
Research of this kind is only valuable if it also honestly documents its own limitations. Three of them deserve to be stated here.
The first concerns score discrepancies. At this stage, three profiles in the corpus show a gap between the score calculated from the detailed interview analysis and the score recorded as reference. These gaps are not artificially corrected: they are flagged and kept as such, since two of them converge toward the same reference score for detailed calculations that are noticeably higher. This convergence suggests that these may not be simple isolated errors of input or judgment, but a possible structural bias in the grid’s weighting, which deserves a methodological examination in its own right rather than a case-by-case correction.
The second limitation touches on a distinction that is subtler than it appears: between the genuine absence of a skill and the absence of evidence in the data. A floor score on an indicator may mean the subject genuinely has a weakness there, or simply that the necessary follow-up question was not asked during the hour-long interview. This ambiguity is not a hidden flaw of the method: it is now treated as a subject of study in its own right, which will call for a targeted second interview for certain profiles.
The third, more general limitation is the size of the corpus. Fourteen profiles are enough to begin distinguishing recurring patterns and formulating solid hypotheses, but not yet enough for strict statistical validation. The correlations observed, notably between age and AC score, should be considered leads to confirm rather than established conclusions.
What this series will explore
This introduction sets the frame: a hypothesis born of a gap in existing tools for thinking about adaptability, a rigorous method built interview after interview, a corpus of fifteen profiles diverse enough to bring out common patterns, and a first hierarchy between what is necessary, what differentiates, and what constitutes excellence in adaptation.
The following articles in this series will each go into the detail of one invariant, individual or organizational, with the concrete mechanisms that compose it, the tensions it reveals, and the questions it still leaves open. Out of respect for the people who agreed to open up without filter during these interviews, the illustrations will remain grounded in real situations without revealing nominal detail or individual scores, which are intended only for internal research use. The goal of this series is not to rank leaders against one another, but to make visible, one by one, the mechanisms that seem to distinguish endured adaptation from chosen adaptation.
If you lead an organization and this research resonates with your own experience of transformation, the study remains open to new interviews. You can also write to us directly at contact@1clusif.org to discuss it.
