It is a product of three conditions: grounding in what matters, reasoning from what reality forbids, and stepping into the adjacent possible, which widens with every step

A position paper: possibility as a function of grounding × first principles × the adjacent possible, tested against the science of modal cognition, prospection, mental contrasting, purpose, self-determination, emergence and measured innovation — and why an economy that credits people for goals they author makes this the central human capacity of the agentic age

ENSI research. Built on a library of 307 primary documents across 16 angles — possibility and modal cognition, prospection and imagination, contemplative science, purpose and meaning, motivation and self-authorship, the physics of information and complexity, the adjacent possible and economic complexity, and the evidence on AI and human agency. Stamped 11 November 2026.


Thinking from infinite possibility is a cognitive capacity, not a belief about outcomes. It has three components. Grounding is the anchoring of choice in a meta-level of what matters — values and a purpose held by the agent, which supply the criteria against which every option is evaluated. First-principles reasoning is the evaluation of options against the constraints reality actually imposes — physical, logical, legal, economic — rather than against inherited categories, roles and precedents. The adjacent possible is the set of states reachable in one step from the present state; it is not fixed, because each step taken adds new states one step away. The capacity is the joint operation of the three: a stable criterion, a correct model of constraint, and an iterated search whose frontier expands as it moves.

Stated as a working model: possibility = grounding × first principles × the adjacent possible, iterated step by step. The form is a product because the conditions are conjunctive. Grounding with no model of constraint yields a stable agent searching a space drawn by someone else. A model of constraint with no grounding yields capable search steered by whatever criterion is most salient — threat, status, or an engineered feed. Both without iteration yield a static option set, and the evidence below shows that a static, vividly simulated future lowers attainment. The multiplicative form is a structural hypothesis, not a measured law. Its nearest empirical tests are interaction effects — goal attainment raises well-being more when goals are self-concordant (β = .11 for the interaction), and mental contrasting makes effort depend on expectancy — and both point the same way.

The hinge of the argument is a single experimental result. In a study of 498 adults, judgements made under a 1,500-millisecond limit classed immoral events as impossible 37.30% of the time against 21.41% after deliberation (z = 5.42), and irrational events 42.10% against 37.86%; for physically impossible events reflection moved judgements the other way, from 79.37% to 85.22% (default possibility, p. 3). The fast modal default is narrower than the feasible set, and deliberation corrects it asymmetrically — more permissive about constraints set by norm and habit, stricter about constraints set by physics. That asymmetry is first-principles reasoning in miniature, and it is the operation this paper generalises.

The popular version of “infinite possibility” fails the tests the evidence sets, and the failures define the construct by exclusion. Belief in one’s own malleability is not the lever: across 63 studies and 97,672 students, growth-mindset interventions moved achievement by d = 0.05, falling to 0.01–0.03 after correction for publication bias (Macnamara and Burgoyne, p. 2, 24–25). Positive simulation of a desired future predicts less attainment, not more (mental contrasting review, p. 1). And where novelty is measured directly, it accumulates sublinearly — Heaps exponents of 0.45 to 0.78 across four large data sets of human activity (correlated novelties, p. 3, 13). “Infinite” is therefore not a claim that every outcome is reachable. It is a claim about the topology of the space: unbounded in its combinations, local in its steps.

The positive half of the thesis is better supported than the popular half. Prospection — the representation and evaluation of possible future states — has been proposed as an organising function of cognition rather than an occasional activity (prospection manifesto, p. 2), and the neuroimaging shows one core network serving remembering, simulating futures and counterfactuals (future of memory, p. 1, 5–7). A self-chosen purpose predicts sustained effort and, observationally, survival; autonomy over goals predicts autonomous motivation across 881 samples. None of these findings shows that possibility is boundless. Together they show that the option set a mind actually searches is a variable — narrowed by speed, threat, imposed goals and inherited categories, widened by reflection, contrast, self-concordant purpose and recombination.

The physical half of the argument comes from formal theory. One research programme proposes stating every law of physics as a claim about which transformations are possible and which are impossible (constructor theory, p. 1); on that view anything no law forbids is open to construction. Condensed-matter theory adds that knowing the base laws does not allow one to deduce the structures built on them, because each level of organisation develops properties of its own (More Is Different, p. 1). The two claims together give the shape this paper defends: the base is narrow and the space above it is not. Both are theory; the first is untested and its author states that its principles “may be false” (constructor theory, p. 39).

The agentic transition raises the stakes. Large language models could affect at least a tenth of the tasks of about 80% of the US workforce, and at least half the tasks of about 19% (GPTs are GPTs, p. 1) — an exposure estimate, not a forecast. As execution is delegated, the scarce human inputs move upstream: choosing the goal, judging the result, originating what does not yet exist. Who sets the goal becomes the central economic variable. Axiocracy — capitalism, amplified for the agentic age — keeps markets, property, prices, profit and competition, and adds an accounting of the value people and agents create against goals and measures agreed before the work starts by those who will be measured, together with a protected sphere of life that is never accounted. Under such rules the person becomes the author of their goals and measures. The capacity that authorship requires is the capacity described here.

The paper proceeds in four movements: what possibility is as a cognitive variable (1–2), the grounding that stabilises the search (3–5), the first principles that define its true boundaries (6–9), and the step-wise expansion and authorship through which it becomes real (10–12). Each principle gives a conceptual image, a six-line definition, the evidence and five ways to build with it. Every evidence line carries a grade: meta-analytic (pooled across studies), trial (one or a few randomised experiments), correlational (cohort, cross-sectional or survey data), or theoretical (formal models, conceptual analysis, theory without a direct test). Null and contrary findings are kept.

The main points

  1. The default possibility set is narrower than the feasible set. Fast modal judgement excludes options that violate norms; reflection restores them and keeps physical limits.

  2. Unconstrained simulation of a desired future closes the space; contrast opens it. Positive fantasy lowers energisation and attainment; desired state, obstacle and plan together raise it.

  3. Grounding is a self-concordant purpose that extends beyond the self. Goals held for one’s own reasons sustain effort, and purpose beyond the self sustains it where self-interest fades.

  4. Threat contracts the simulated future; prepared responses restore it. Distress lowers the specificity of simulated futures, and pre-committed if–then plans outperform in-the-moment regulation.

  5. Identity-bound certainty terminates search. A familiar solution suppresses better ones, and the rate of belief updating predicts forecasting accuracy more than ability does.

  6. Inherited categories fix the visible subset of the option space. Conceptual mappings run below awareness, and memory retrieves by surface category rather than by structure.

  7. A first principle states what is forbidden; everything else is open to construction. True constraints are few and often far from customary ones.

  8. Constraints underdetermine outcomes. Each level of organisation has properties of its own, so the space of constructions above the base laws is open.

  9. Novel options are recombinations of mastered structure. Simulation recombines stored elements; structural analogy widens the space, and retrieving the distant analogue is the bottleneck.

  10. The adjacent possible expands locally and sublinearly. Each novelty opens related novelties; leaps beyond the adjacent set rarely land, and combinatorial take-off is not foreshadowed.

  11. Autonomy over goals and measures is the motivational condition of possibility. Imposed goals and controlling rewards reduce intrinsic motivation; goals agreed in advance by those measured restore authorship.

  12. When agents execute, the human contribution is goal-setting, judgement and origination. Agents can serve as coach, mirror and red-team; delegating the goal itself removes the grounding factor.


1. The default possibility set is narrower than the feasible set

Metaphor: A lit circle on a dark plane — the plane is what reality allows, the circle is what fast judgement illuminates.

Definition:
Every mind computes a fast, default representation of what is possible before it deliberates.
That default is a subset of the feasible set, from which options that violate norms or habits are silently excluded.
In the default, the modal judgements “could” and “should” are nearly the same judgement.
Deliberation widens the subset where the exclusion was normative and narrows it where the limit is physical.
The capacity to simulate specific futures sets a further ceiling on how large the searched set can be.
Thinking from possibility begins as the deliberate correction of a measured bias, not as an act of faith.

Why it holds:

  • Under a 1,500-millisecond limit, 498 participants judged immoral events impossible 37.30% of the time against 21.41% after deliberation, and irrational events 42.10% against 37.86%, while ordinary and improbable events were unaffected and physical impossibility rose from 79.37% to 85.22% with reflection (default possibility, p. 3). Grade: trial — a randomised timing manipulation in one paper, online US samples and vignettes.

  • Different modal words (may, might, could, ought, should, possible) converged on one default set when answered fast (mean r = 0.893 against 0.830 on reflection, d = 0.754); for immoral events they correlated 0.558–0.919 when fast and −0.016 to 0.572 after reflection, and a mediation analysis indicated that people feel “forced” to act morally because the default already excludes the alternatives (p. 4–6). Grade: trial; the outcome is which options come to mind, not behaviour.

  • A short episodic-specificity induction — training in recalling concrete detail — increased the detail of simulated futures, raised hippocampal activity and improved both means–end problem solving and divergent thinking (hippocampus and imagination, p. 20). Grade: trial — single-laboratory experiments, no pooled effect sizes.

  • In 267 people with aphantasia against 203 controls, the vividness of simulated future events was sharply lower (r = 0.63) while spatial navigation was preserved (r = 0.08, n.s.), so the capacity to represent futures varies as a measurable trait (aphantasia cognitive profile, p. 6–7). Grade: correlational — self-report, self-selected online sample.

  • Clinical states narrow the set: suicidally depressed patients simulate less specific futures, using the same core network that serves remembering (prospective brain, p. 1–4), and generalised anxiety has been characterised as “the chronic expectation that something unspecified but awful will soon occur” (prospection manifesto, p. 17–18). Grade: correlational clinical comparison; the second claim is theoretical.

How to build with it:

  • Before any consequential decision, list the options rejected in the first seconds and the reason for each exclusion.

  • Classify every exclusion as either a physical, logical, legal or arithmetic constraint, or a norm, habit, role or preference.

  • Ask “could” and “should” as two separate questions, in that order.

  • Remove time pressure where the option set matters; a speeded choice inherits the default.

  • Train specificity: describe each candidate future in concrete detail — sequence, actors, resources — before judging it.


2. Unconstrained simulation of a desired future closes the space; contrast opens it

Metaphor: A map with the destination drawn in colour and the terrain between left blank.

Definition:
A vivid simulation of a desired future feels like an expansion of possibility.
On its own it functions as anticipatory consumption: the reward is experienced early and energisation falls.
Contrasting the desired state with the present obstacle converts the simulation into a test of feasibility.
When expectancy is high the contrast mobilises effort, and when it is low it licenses disengagement.
A possible self alters behaviour only when it carries a strategy, and it is steadier when paired with a feared counterpart.
Possibility, on this evidence, is a discipline of contrast rather than a mood of hope.

Why it holds:

  • Across “over 15 years of research”, “the more positive a person’s fantasies about the future, the less successful she is in realizing these fantasies”, in health, interpersonal and academic outcomes measured up to two years later (mental contrasting review, p. 1). Grade: correlational longitudinal studies, summarised in a narrative review by the method’s originator; no pooled effect sizes.

  • In four experiments, induced positive fantasies lowered energisation — measured subjectively and as systolic blood pressure — relative to questioning, negative or factual thoughts; mental contrasting combined with if–then plans improved grades, exercise over four months and diet over two years (p. 1–4). Grade: trial — several randomised studies, not pooled.

  • Among 160 low-income eighth graders, 82% of expected selves concerned school, yet only selves carrying concrete strategies predicted more homework (β = 0.20), better participation and higher grades, explaining 8% of multivariate variance across five outcomes — and they changed behaviour without changing feeling about school (ΔR² = .00) (possible selves as roadmaps, p. 10–11). Grade: correlational, one school year, small effects.

  • In 238 adolescents, more than 81% of the least delinquent held at least one balanced pair of expected and feared selves against 37% of the most delinquent, and global self-esteem did not track delinquency (possible selves and delinquency, p. 10–11). Grade: correlational, cross-sectional, one city.

  • Belief does not substitute for enactment: belief-change interventions moved achievement by d = 0.05 across 63 studies (Macnamara and Burgoyne, p. 2), while completing two concrete trait-relevant behaviours a week shifted traits by about 0.17 SD over a semester (Hudson following through, p. 7). Grade: meta-analytic (preregistered) against trial.

How to build with it:

  • State the desired outcome in one sentence, then the principal obstacle located in oneself — a habit, belief or emotional response.

  • Convert that obstacle into an implementation intention: “if situation X, then response Y”.

  • Attach a concrete strategy to every hoped-for self; a possible self without one has no measured effect on behaviour.

  • Name the feared self in the same domain and hold it as a boundary condition, not as a forecast.

  • Where the contrast shows expectancy is low, disengage deliberately; releasing an infeasible goal frees resources for the adjacent possible.


3. Grounding is a self-concordant purpose that extends beyond the self

Metaphor: A fixed point in a rotating frame — everything else can move because one thing does not.

Definition:
Grounding is the meta-level of choice: the values and purpose against which options are evaluated.
It is a criterion, not a state of calm and not the absence of aims.
Its strongest form is a purpose that is meaningful to the self and of consequence beyond the self.
A goal is grounded when it is self-concordant — held from interest or core value rather than from pressure.
With a grounded criterion, any method, role or template can be abandoned without loss of direction.
Without one, the most salient external agenda supplies the criterion by default.

Why it holds:

  • In three longitudinal studies (n = 169, 152 and 73), self-concordant goals attracted more sustained effort, effort carried the effect on attainment (β = .76), attainment raised well-being more for concordant goals (interaction β = .11), and attaining non-concordant goals did not raise well-being (self-concordance model, p. 3–6). Grade: correlational — small student samples over one semester.

  • A single 20–30-minute exercise linking schoolwork to contributing beyond the self raised STEM grades (d = .11; d = .21 for lower performers) in 338 students, and in 429 participants it left them solving 36% more problems than controls once a tedious task grew long (d = .32); self-oriented motives did not consistently produce the effect (Boring but Important, p. 1, 17–18, 25–26). Grade: trial — small effects, short follow-up; the intervention family has replicated unevenly.

  • Among 6,985 adults over 50, the lowest purpose band died at 2.43 times the rate of the highest over four years after adjustment for depression, anxiety and optimism (purpose and mortality, p. 1, 7); among 6,163 adults followed for 14 years, each SD of purpose went with 15% lower mortality regardless of age (purpose across adulthood, p. 4–5). Grade: correlational cohort; the second measure had internal consistency of only α = .36.

  • The construct is defined as “a stable and generalized intention to accomplish something that is at once meaningful to the self and of consequence to the world beyond the self” (defining youth purpose, p. 3); about one in five high-school and one in three college students report one (Psychology of Purpose, p. 13), and having meaning and searching for it are nearly independent (r = −.19) (Meaning in Life Questionnaire, p. 4). Grade: theoretical definition with descriptive survey data.

  • Grounding is not a quick exercise: a celebrated 15-minute values-affirmation effect was not significant in 77% of 1,566 analytic specifications, and the effect on its target group was null in 97% (self-affirmation reanalysis, p. 4, 7). Grade: reanalysis of a single trial — a null result.

How to build with it:

  • Write the purpose in two clauses: what matters to you, and whom or what it serves beyond you.

  • Test each current goal for concordance: would it still be pursued if no one observed or rewarded it?

  • Name the small set of values that will not be traded for any outcome, and treat them as fixed constraints in every plan.

  • When a method or role fails, return to the purpose before selecting the next method.

  • Build purpose by the routes associated with it — long-term mentoring, structured conversation about what matters, service (Psychology of Purpose, p. 17–19) — and treat one-off writing exercises as insufficient.


4. Threat contracts the simulated future; prepared responses restore it

Metaphor: An aperture that closes as the light grows harsher, until only the nearest object is in focus.

Definition:
Threat acts on prospection: it fills the simulated future with aversive outcomes and lowers its specificity.
Engineered emotion acts on attention: it determines which options are represented at all.
A steady agent is one whose option set is not being contracted by fear or by an external designer of salience.
Steadiness is not the absence of affect but a repertoire of responses selected in advance.
In-the-moment regulation is weak, while pre-commitment and control of inputs are strong.
Restoring the aperture is a precondition for searching the whole space.

Why it holds:

  • Across the instructed-regulation literature, redirecting attention had no effect on emotional outcomes (d = 0.00), suppression a small one (0.16) and reappraisal a small-to-medium one (0.36), whereas if–then plans outperformed no instruction by d = 0.91 and goal intentions alone by 0.53 (implementation intentions meta, p. 6, 24, 31–35). Grade: meta-analytic.

  • An estimated 31% of social-media use is driven by self-control problems (digital addiction experiment, p. 2, 6), yet ten trials of social-media abstinence found pooled well-being effects of essentially zero (Lemahieu abstinence meta, p. 7): engineered salience costs agency more than mood, and the lever is authorship of inputs rather than abstinence. Grade: trial (about 2,000 participants) and meta-analytic.

  • Across 136 randomised trials with 11,605 adults, mindfulness programmes reduced anxiety against no intervention (SMD −0.56), but showed no superiority over specific active alternatives such as exercise, every prediction interval crossed zero, and 89% of trials did not report measuring adverse events (Galante mindfulness meta, p. 1–2, 15). Grade: meta-analytic, preregistered; all trials at high risk of bias.

  • In a randomised trial of 5,049 adults, short 5–10-minute digital practice was no more likely than ordinary internet use to produce a distressing experience (OR 1.05), but 10 minutes carried more risk than 5 (OR 1.42) (digital meditation RCT, p. 1, 8); among practitioners recruited for difficult experiences, 73% reported moderate-to-severe impairment and 72% of cases arose during or after retreats (Lindahl meditation challenges, p. 15, 21). Grade: trial, and a qualitative study that does not yield prevalence rates.

  • Distress lowers the specificity of simulated futures in depression and schizophrenia in proportion to symptoms, because remembering and simulating share one constructive system (prospective brain, p. 1–2). Grade: correlational clinical comparison, largely from the authors’ own studies.

How to build with it:

  • Write if–then plans for the three situations that most reliably contract your option set.

  • Set rules, not moods, for what enters attention: feeds, notifications, news and the order of the first hour of the day.

  • When fear forecasts an outcome, record the forecast as a probability and score it later.

  • Use short practices that return attention to the present; treat intensive retreat practice as a serious intervention with documented risks.

  • Defer consequential choices made under externally manufactured urgency.


5. Identity-bound certainty terminates search

Metaphor: A search that halts at the first acceptable answer and records it as the best one.

Definition:
The form of ego that most narrows possibility is not grandiosity but the need to be right.
It binds identity to a known solution and defends that solution against better ones.
Expertise strengthens the effect, because a familiar answer arrives faster and ends the search sooner.
Loosening it means holding beliefs as revisable at a known rate, in response to evidence.
On the evidence this is a measurable habit of updating more than a mystical state.
An agent that revises keeps more of the option space live than an agent that defends.

Why it holds:

  • When a familiar five-move solution was available beside a shorter three-move one, expert chess players performed at roughly the level of players three standard deviations weaker; experts predicted success rates of 86%, 74% and 59% for three groups, and the observed rates were 50%, 18% and 0% (expert Einstellung, p. 1, 11–12). Grade: trial — laboratory experiment with small expert samples.

  • Across more than 150,000 forecasts by 743 forecasters, the strongest behavioural predictor of accuracy was the frequency of belief updating (−0.45 with error), ahead of deliberation time and measured ability (drivers of forecast accuracy, p. 7–9). Grade: correlational, within a large forecasting tournament.

  • Of 2,994 new business owners, 33% rated their own chance of success at 10 out of 10, against base rates showing about half of such firms survive five years (Cooper on founder odds, p. 1, 7). Grade: correlational survey.

  • Self-transcendent states — decreased self-salience, increased connectedness — are measurable: in a double-blind trial with an active control, about two thirds of psilocybin recipients ranked the experience among the five most meaningful of their lives (self-transcendent experience, p. 8), and ego dissolution and ego inflation load on separate, nearly orthogonal factors (ρ = −0.110) (Ego-Dissolution Inventory, p. 1, 6). Grade: trial with small, selected samples; correlational scale validation.

  • Contemplative practice is no guaranteed exit from self-interest: across 22 randomised trials, meditation’s effect on compassion was not significant against active controls and appeared only when the teacher co-authored the study (r = 0.42), with no effect on aggression or prejudice (Kreplin prosocial meta, p. 5). Grade: meta-analytic; 61% of included studies rated weak.
