Condition 1 — Ericsson et al., 1993
"Target a specific skill just beyond current ability."
One distortion per session
Every episode targets a single, specific diagnostic failure — not a category. Blended CAC Blindness is a different rep from Conversion Quality Illusion. 50 episodes, 50 targeted skills.
Condition 2 — Ericsson et al., 1993
"Practice must be highly structured and goal-directed."
Fixed 5-stage structure — every session
Every episode follows the same five-stage sequence. Structure is the mechanism that separates deliberate practice from passive viewing.
Condition 3 — Ericsson et al., 1993
"Immediate, informative feedback is required."
Diagnostic quiz with corrective feedback at close
Every episode ends with a quiz — three options, one correct — with detailed feedback explaining why each answer is right or wrong. Immediate and specific to the distortion just covered.
Condition 4 — Ericsson et al., 1993
"Focused effort and full concentration required."
5-minute constraint forces focus
The time constraint is not a limitation — it's the mechanism. 5 minutes of full attention on one concept produces better encoding than 45 minutes where attention drifts across many.
Condition 5 — Ericsson et al., 1993
"Practice must be sustained cumulatively over time."
50 episodes — designed as a cumulative library
Each episode is a rep in a cumulative practice sequence. Distortions are connected — Blended CAC Blindness (EP05) informs how you read Paid-Organic Cannibalization (EP07). Designed for repeated use, not one-time consumption.
Ericsson et al., 1993 · Psychological Review
Expertise is not accumulated experience. It is designed practice.
Ericsson, Krampe, and Tesch-Römer established that differences in expert performance are systematically linked to the quality of deliberate practice — not years of experience. Passive formats, including high-quality video, do not meet the conditions required to build expert performance. Light2Path R03 documents how each of the five conditions maps directly to episode structure.

Schmidt & Rikers, 2007 · Medical Education
Pattern recognition is built through case exposure — not factual review.
Schmidt and Rikers established that experts recognize patterns faster not because they know more facts, but because repeated case exposure builds "illness scripts" — named failure patterns that activate on partial cues. Each Light2Path episode is one structured case exposure. Across 50 episodes and 7 pillars, practitioners build the case library expert diagnosis requires.

The workforce has strong declarative knowledge and weak pattern recognition. That's precisely what passive formats produce.
The AMA's 2025 workforce survey finds data interpretation and ROI judgment as the top employer-reported gaps. R01 frames this precisely: marketing education produces declarative knowledge — the ability to recall frameworks. It does not produce diagnostic expertise — the ability to recognize when a metric is structurally misleading.

Rodman et al., 2023 · JAMA Network Open
AI cannot substitute for the diagnostic judgment this session builds.
Rodman et al. found that clinicians and AI diverge most when new information requires contextual reframing. AI processes what the inputs show. The skill they cannot supply is recognizing when the measurement frame itself is wrong — the skill every 5-minute session is specifically designed to build.
