Phone in view cuts working memory
A 2017 study found that merely having a smartphone visible — even face-down and silenced — significantly reduces working memory capacity and fluid intelligence.

Flow States: Engineering Deep Absorption
At 1:15:33 · chapter starts 1:09:35
Birnie introduces Mihaly Csikszentmihalyi's concept of flow — the state of complete absorption where time disappears, action seems effortless, and self-consciousness dissolves — as one of positive psychology's most validated and important constructs. Flow appears across all cultures and activities: running, dance, woodworking, programming, cooking, music. The paradox is that getting into flow often requires deliberate practice that is distinctly not a flow state and is not enjoyable — there's a cost barrier to entry. Three reliable preconditions for flow are identified: clear goals (know exactly what you're working on), immediate feedback (real-time information about progress), and a challenge approximately 4% beyond current skill (enough difficulty to demand full attention without triggering overwhelm). The discussion gets personal: Manson describes tricking himself into flow by bargaining with himself to 'just write the intro,' using gamification software like Scrivener's progress bars, and finding that writing flows quickly while woodworking never would. Birnie contrasts his own preference for physical, visible progress as feedback. The default mode network's shutdown during flow — loss of self-reference, ego quieting — is linked to both the happiness research and the episode's broader theme of productive focus. A teaser is dropped: flow and ADHD hyperfocus are related but crucially different.
Flow Is Engineering, Not Magic
Flow isn't a mystical gift bestowed on the talented. It has three reliable preconditions: clear goals, immediate feedback, and a challenge roughly 4% beyond your current skill. Video games have these nailed. Your job probably doesn't — but it can.
Smartphone in View = Lower IQ in the Room
A 2017 study found that having your smartphone visible — even face-down and silenced — measurably reduces working memory capacity and fluid intelligence. The most effective thing you can do for your focus right now costs nothing: put your phone in another room.
The ADHD Paradox: Same Problem, Different Format
ADHD isn't really an attention deficit — it's an attention regulation problem. The same person who can't fold laundry for 6 minutes can play video games for 6 hours. Both are failures of intentionality: one can't start, the other can't stop. The real issue is that the switch between modes isn't under voluntary control.

A key study finding that we have a 'credit card's worth of plastic' in our bodies was likely skewed because researchers used nitrile gloves that shed plastic particles onto the microplastic detector.
Hyperactive amygdala + frayed PFC link
Emotionally sensitive people have a hyperactive amygdala, an underactive prefrontal cortex, and a frayed connection between the two — making emotional regulation structurally harder.
