- Scene 5 b-roll 'screen data erasing pixels' directly contradicts the narration 'nothing is erased' — visually undermines the key corrective beat; swap for a filing cabinet, archive drawer, or folder-closing metaphor
- Researcher attribution is accurate and differentiated: Zacks for event segmentation theory, Radvansky for the doorway-specific retrieval dip — this specificity is what separates it from generic brain-content
- 'Adaptive architecture, not a malfunction' is an original reframe with no slop residue; it earns its emphasis beat
- Total runtime ~31 seconds is tight for the concept density; s3 and s5 each carry a distinct mechanism — consider 1–2 seconds of padding to let retrieval-cue logic land before the fix
- CTA is clean, low-hype, and on-brand; no manufactured urgency

Script
hookYou walked into the kitchen and forgot why.
"Neuroscientists call it event boundary segmentation."
"Gabriel Radvansky found the brain organizes memories by physical location."
"Cross a doorway, and the previous mental episode closes. A new one opens."
"Working memory clears for the new space. That's the design."
"To get it back, walk back. The room is the retrieval cue."
"Your brain filed it. You just need to return to where you left it."

17:20:40revising (QA 8/10): Radvansky named and cited correctly — a real researcher with real published work on this, strong credibility anchor; 'Adaptive architecture, not a glitch' is the standout line — precise, reframey, memorable; 'Working memory wipes clean' is a slight oversimplification; more accurate is that retrieval cues become room-bound, not that memory is erased — defensible for lay audience but watch the precision
17:20:09fact-check flagged: Attribution is incomplete: the mechanistic framing that mental 'episodes close' at boundaries derives from Jeffrey Zacks' Event Segmentation Theory (Zacks et al., Psychological Review 2007); Radvansky's lab demonstrated the behavioral doorway effect but does not own the full explanatory mechanism—crediting only Radvansky is misleading.; 'Event boundary segmentation' is non-standard terminology; the established label for the theory is 'event segmentation' (Zacks et al.) and for the phenomenon is 'the doorway effect' (Radvansky et al.).; 'Working memory wipes clean' overstates the empirical finding; Radvansky's studies show degraded retrieval and impaired recall after crossing a boundary, not complete erasure of working memory content—the difference is material for a fact-check.
