Brain games can train their own rule changes. They have not been shown to make people broadly more adaptable—and routine or predictability may be the right support.
This tutorial teaches how to audit a completed two-rule card-sort record without asking anyone to sort cards. You will derive the correct bin from the visible rule, compare it with a fictional chosen bin, and call an error perseveration only when the old rule predicts the recorded wrong response. You will also separate a supported repeat from the first switch and keep personality, autism and clinical claims out of the result.
This dossier explains the evidence and its limits. It is not a diagnosis, personal recommendation, assessment, clearance, performance promise or training programme. Actionable teaching appears only when the canonical Power record explicitly authorises it.
Complete bounded explanation
What this power means.
Capability to develop or express cognitive flexibility in a declared context without inheriting broader claims.
What the current evidence supports
People improve on practiced switching games, but active-controlled trials do not establish broad cognitive flexibility or real-world adaptability.
How to observe or measure it without overclaiming
Set-shift cost and rule-change errors are task measures; they do not establish creativity, open-mindedness, resilience or social conformity.
Myth
Become adaptable to anything
Metric
Rule-change cost and errors plus a separate meaningful adaptation outcome
Boundary
A game cannot establish creativity, resilience, open-mindedness or human worth.
Negative and limiting findings
A large 58-session active-controlled trial found no training-specific cognitive benefit; improvements were consistent with retest, expectancy or motivation.
Claims this evidence cannot support
Become infinitely adaptable
Train away autistic rigidity
Brain games make you open-minded
Flexibility prevents cognitive decline

How to learn this Power now.
This tutorial teaches how to audit a completed two-rule card-sort record without asking anyone to sort cards. You will derive the correct bin from the visible rule, compare it with a fictional chosen bin, and call an error perseveration only when the old rule predicts the recorded wrong response. You will also separate a supported repeat from the first switch and keep personality, autism and clinical claims out of the result.
Frame the questionState the capability claim narrowly enough that evidence could support or limit it.
Map the evidenceDistinguish existence, measurement, trainability, retention, transfer, safety and functional value.
Find uncertaintyIdentify small samples, proxy measures, missing controls, null findings and unresolved authority questions.
Compare alternativesConsider competing explanations and what evidence would change the current treatment.
Stay non-operationalUse the record for research literacy only until a separate gate authorises instruction.
Authority boundary: Titan teaches a complete Power-specific research method because operational capability practice is not currently justified. The method is Power-specific; its actionability follows this treatment.
Citation roles are explicit. A source may support existence or trainability while simultaneously limiting transfer, certainty, generalisation or safety.

Current teaching and evidence boundary
The next gate remains visible.
No external confirmation is required for the current bounded explainer permission. Guide permission remains not ready; any guide, stronger efficacy, generalisation, protocol, promotion or independent-validation claim requires a new adjudication.
A complete governed research tutorial is available at /tutorials/pwr-104/. It supplies a fictional record-analysis method, worked example, corrections, delayed review and evidence boundary. It does not authorise capability self-practice.
