Public Skills
thinking-thought-experiment
by tjboudreaux
'When a real test is too rare, large, or irreversible, run a controlled counterfactual: isolate one variable, fix conditions, trace the mechanistic chain, and bound what the result implies.'
thinking-model-router
by tjboudreaux
When unsure which thinking skill fits, map domain and problem type, then return NONE or one primary skill by default (at most three complementary).
thinking-bounded-rationality
by tjboudreaux
Use when search or investigation could run forever. Set an explicit good-enough threshold first, then stop at the first option that clears it.
thinking-circle-of-competence
by tjboudreaux
Use when a specific claim may lack grounding. Check evidence boundary, size wrongness cost, then answer, fetch, or abstain — never confabulate.
thinking-cynefin
by tjboudreaux
When the right response mode is unclear, classify the cause-effect domain first; decompose disorder.
thinking-effectuation
by tjboudreaux
Under genuine uncertainty with no reliable forecast, inventory means, cap downside at affordable loss, act for commitments, and let goals emerge from controllable moves.
thinking-first-principles
by tjboudreaux
When a constraint is treated as fixed, separate physics from convention, keep only independently supported primitives, and rebuild the simplest solution that satisfies real constraints.
thinking-five-whys-plus
by tjboudreaux
When a fault is localized and the proximate cause is known but the systemic root is not, chain evidence-linked whys with a counterfactual stop and a countermeasure.
thinking-jobs-to-be-done
by tjboudreaux
Deciding what to build or why adoption fails. Recover the progress users hire a solution for under a circumstance, then rank by outcome and competing workarounds.
thinking-kepner-tregoe
by tjboudreaux
Use when a selective defect needs IS/IS-NOT difference analysis or a consequential option choice needs must/want weighting and adverse-consequence comparison.
thinking-lindy-effect
by tjboudreaux
Use when longevity of a non-perishable option matters. Treat survival duration as a remaining-life prior, then check domain drift before favoring the proven.
thinking-map-territory
by tjboudreaux
When a claim, doc, test, metric, or assumption conflicts with observed behavior, stop theorizing from the map and verify the live code or data; let territory overrule.
thinking-margin-of-safety
by tjboudreaux
When provisioning, setting a limit, or committing an estimate under uncertainty, size a buffer to residual error and the cost of breach—not to the optimistic edge.
thinking-model-combination
by tjboudreaux
When one mental model leaves a material blind spot on a multi-domain or high-stakes problem, sequence complementary models with named roles and a conflict rule.
thinking-ooda
by tjboudreaux
Use under time pressure when the situation is still changing and you must act before certainty — cycle Observe→Orient→Decide→Act on ~70% confidence, then re-observe.
thinking-opportunity-cost
by tjboudreaux
Before committing scarce time, people, or money, name the best forgone use of those resources and the value delta of the chosen path versus that alternative.
thinking-pre-mortem
by tjboudreaux
Before committing to a plan or launch, assume it already failed and reason backward through concrete causes — convert failure paths into mitigations, gates, and stop checks.
thinking-probabilistic
by tjboudreaux
Use when forecasting, estimating, or sizing risk — anchor on base rates, give ranges, update prior→likelihood→posterior on evidence, and factor unmeasured quantities into order-of-magnitude bounds.
thinking-red-team
by tjboudreaux
For authorized security review of code, auth, or APIs you control, model the attacker, map the attack surface, and report only findings with a reproducible exploit path and verified mitigation.
thinking-steel-manning
by tjboudreaux
Before rejecting a proposal or reflexively agreeing, build the strongest faithful opposing case, state agreement conditions, then update or reaffirm.
thinking-reversibility
by tjboudreaux
Before heavy deliberation, classify the decision as cheap or costly to undo; decide two-way doors fast and stage one-way doors to preserve options.
thinking-scientific-method
by tjboudreaux
When a symptom has several plausible causes, rank falsifiable hypotheses and run the cheapest discriminating observation first; prefer least-assumptive survivors only after evidence fit.
thinking-second-order
by tjboudreaux
When a change has effects past the immediate fix—incentives, scale, feedback—trace consequence chains with timing and probability before committing.
thinking-socratic
by tjboudreaux
When a request is vague, assumption-laden, or "obvious," ask the few load-bearing questions that expose hidden requirements before building or committing.
thinking-systems
by tjboudreaux
When behavior is emergent across components—fixes elsewhere break, loops/delays dominate—map boundary, stocks/flows, feedback, archetypes, then rank leverage.
thinking-theory-of-constraints
by tjboudreaux
When throughput or latency is pipeline-limited, identify the single binding constraint and exploit, subordinate, elevate, then recheck—ignore non-constraints.
thinking-triz
by tjboudreaux
When two design requirements seem mutually exclusive, name the contradiction, separate conflicting states, then invent a concrete no-compromise resolution.
thinking-via-negativa
by tjboudreaux
Use when the reflex is to add a feature, layer, or process. Prefer removing harmful or nonessential elements first, with an irreversibility guard before deletion.
tools-p4-basics
by tjboudreaux
Fundamental Perforce operations including sync, edit, add, delete, submit, revert, and file state management.
tools-p4-shelving
by tjboudreaux
Perforce shelving for code review, sharing work-in-progress, backup, and collaboration workflows.
tools-p4-changelist
by tjboudreaux
Perforce changelist management including creating, editing, moving files between changelists, and pending change workflows.
