This is the kind of insight I can’t find anywhere else. Thanks for sharing!

GReat framework on time slippage, but the neuroscience needs revision. You claim: "even unproductive effortless exertion leaves you with less time and energy" because both social media and deep work use the same neurochemistry.

This conflates different mechanisms:

1. Metabolic cost is NOT equal. Deep cognitive work consumes significantly more glucose than social media scrolling (which relies primarily on visual pattern recognition + emotional responses). fMRI studies show higher prefrontal cortex activation during complex tasks.

2. Neurotransmitter release differs fundamentally:

Social media: intermittent dopamine spikes (variable ratio reinforcement) → rapid desensitization

Flow state: sustained dopamine + serotonin + norepinephrine → more stable reward system

3. Ego depletion as a "resource" is contested. Modern research (Inzlicht, Kurzban) suggests the deficit isn't resource exhaustion, but motivation loss due to dopamine dysregulation—different mechanism entirely.

The real problem: After 6 hours of social media, you're demotivated because dopamine crashed. After 6 hours of flow work, you're metabolically fatigued. Same outcome (can't focus next), different causes.

Also: The Ulm University study on perceived importance—can you link the specific peer-reviewed source? I couldn't locate it.

The core insight about time tracking is solid. The neuroscience deserves more precision.
