Explanation is not permission.

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 visual search in a declared context without inheriting broader claims.

What the current evidence supports

Visual search is trainable for defined targets and contexts, yet low-prevalence targets remain easy to miss and broad transfer is not guaranteed.

How to observe or measure it without overclaiming

Predeclare target class, prevalence, sensitivity, false alarms, response time and unfamiliar-scene transfer; keep speed–accuracy trade-offs visible.

Myth

Human anomaly scanner

Metric

Sensitivity, miss and false-alarm rates on rare unfamiliar targets

Boundary

Fast finding of frequent trained targets does not establish expert anomaly detection.

Negative and limiting findings

  • Rare targets were missed at disturbingly high rates.
  • Contextual learning can improve a repeated scene without improving a new one.

Claims this evidence cannot support

  • Photographic scanning
  • Never miss an anomaly
  • One game trains every search job
  • Reaction time proves safer inspection

How to learn this Power now.

The learner completes target-present and target-absent grids using a declared scan path and improves sensitivity without more false alarms or revisits.

  1. Get readyUse a seated, low-stakes task; no medical images, baggage screening or hazards.
  2. Learn the method8 concrete steps teach the permitted method from start to finish.
  3. See right and wrong6 comparisons show correct or safer execution beside common wrong or riskier choices.
  4. PractiseUse four to eight new grids once or twice weekly. Progress only after accuracy and false alarms are stable; vary prevalence or clutter one at a time.
  5. Check progressOn target-present grids, a hit requires the exact keyed row and column; an absent answer or wrong coordinate is a miss/localisation error. On absent grids, any marked location is a false alarm and absent is a correct rejection. Report hits divided by present grids and false alarms divided by absent grids, plus stopping time, revisits, skipped rows, first path break, prevalence and grid configuration.

Authority boundary: Titan teaches a concrete low-stakes method step by step while keeping evidence and transfer claims bounded. The method is Power-specific; its actionability follows this treatment.

Current teaching and evidence boundary

The next gate remains visible.

External confirmation is required before higher-authority use because: a clinical, high-risk or regulated configuration.

It contains a plain-English method, 8 ordered steps, a worked example, right-versus-wrong comparisons, specific mistakes and corrections, practice, measurement, accessibility, stopping rules and evidence.
