- Hook lands hard — 'Decided at 9am' is counterintuitive, concrete, and earns the open.
- Obama suit example is the strongest beat: real, sourced, specific. It carries the video.
- Technical validity is the ceiling-breaker: ego depletion has faced serious replication failures — Hagger et al. 2016 (25-lab pre-registered replication) found no effect; the glucose mechanism is especially contested in current literature.
- Critical inconsistency: storyboard s4 hedges correctly ('the glucose link is still debated') but the narration script asserts 'It shows up in your biology, not just your mood' — these conflict. A premium channel cannot run both. Commit to the honest hedge throughout.
- 'Not a feeling. A biological measurement.' is the most overconfident line in the script and the most likely to draw credibility challenges in comments. Cut it or replace with specific measured effect sizes.
- The Danziger parole-judge study is compelling but has been critiqued on alternative explanations (post-break food vs. glucose reset); citing 'judges and parole boards' as clean evidence is editorially exposed without a caveat.
- Anti-slop capped by two problems: (1) decision fatigue + Obama suits is one of the most replicated productivity-content frameworks on the platform, (2) the 'tank' metaphor is ubiquitous. Naming a specific researcher (Baumeister, or a critic like Inzlicht) or one hard measured number from an actual study would separate this from the mass.
- Visual structure is genuinely clean — one idea per scene is executed correctly, b-roll choices are grounded, before/after contrast in s6 works.
- Passes conditionally: resolve the narration/storyboard hedge contradiction, soften the biology overclaim, and consider crediting or critiquing ego depletion by name before export.

Title
Decision Fatigue Explained: Why Your Willpower Runs Out by Evening
Description
Every decision you make all day burns real glucose in your prefrontal cortex. By evening that supply is measurably lower. Not a feeling. A biological pattern researchers call ego depletion. Front-load your hardest choices. That is the only time the tank is full. #decisionfatigue #willpower #neuroscience #decisionfatigue #willpower #neuroscience

That late-night snack was decided at 9am. Every choice all day drains the same mental fuel. By evening, your prefrontal cortex is running low. Not a mood. A measurable biological shift. What is one decision you can move to morning?

Script
hookThat late-night snack was decided at 9am.
"That late-night snack was decided at 9am."
"Every choice you make all day, ordering coffee, answering emails, picking a meeting time, burns real glucose in your prefrontal cortex."
"By evening, that supply is measurably lower. Researchers call it ego depletion. It shows up in your biology, not just your mood."
"Barack Obama wore only grey or blue suits. His reason: 'I'm trying to pare down decisions. I have too many other decisions to make.'"
"Your evening failures are not a character flaw. You just spent your fuel before dinner."
"Move your hardest choices to morning. That is the only time the tank is full."

02:58:10revising (QA 7/10): Obama suit anecdote is the one genuinely specific anchor — it earns its place and lands well.; Ego depletion is presented as settled science; the 2011-2016 replication failures (Hagger et al. 2016 meta-analysis, Carter & McCullough) are ignored entirely — this is a known contested finding and omitting it is a technical validity problem, not a minor caveat.; 'Researchers call it ego depletion, documented in lab studies measuring blood glucose in judges, parole boards' — the Danziger parole board study is about food breaks and decision fatigue broadly, not glucose measurement specifically; conflating these is imprecise.
02:57:54fact-check flagged: Ego depletion replication failure: The core thesis rests on Baumeister's ego depletion hypothesis, which failed a large pre-registered multi-lab replication (Hagger et al., 2016, 23 labs). The script presents it as settled biology ('Not a feeling. A biological measurement') when the scientific status is actively contested and many researchers consider it unreliable.; Blood glucose in judges is a conflation: The Danziger et al. (2011) Israeli parole-board study tracked decision outcomes over session time — it did not measure blood glucose. Separately, Baumeister's lab studies used glucose drinks, not judicial data. Merging these into 'blood glucose measured in judges' is a factual error. Additionally, the Danziger study itself has been reanalyzed (Glöckner 2016; Andreas & Achtziger 2020) showing the pattern may reflect case-ordering, not decision fatigue.; Obama wore black suits too: Multiple photographs and contemporaneous reporting confirm Obama also wore black suits. 'Only grey or blue' is an exaggeration; the accurate version is that he limited his wardrobe to a small set of colors including black.; '100% of choices share one fuel tank' (scene s3): Presents as established fact a model (the glucose-as-willpower-fuel hypothesis) that is specifically the contested part of ego depletion theory. Glucose levels in the brain are tightly regulated and do not drop measurably from ordinary decision-making under normal conditions — this mechanism has not been reliably demonstrated.; Narration line 'that supply is measurably lower by evening' overstates certainty: Diurnal variation in executive function exists (circadian research), but attributing it specifically to glucose depletion from decision-making is not supported by current evidence. The two phenomena — time-of-day effects and ego depletion — should not be conflated as one causal chain.
