[+0] The precautionary principle requires treating 15% structural brain changes as harmful until proven otherwise given adolescent vulnerability. [i]
[+0] Historical precedent from lead exposure shows 10-15% brain volume reductions caused lasting cognitive deficits across populations. [i]

[+0] Adolescent brain development requires environmental enrichment, which excessive screen time demonstrably reduces by 3-5 hours daily. [i]

[+0] Gray matter reductions exceeding 10% in prefrontal regions correlate with impaired executive function in longitudinal studies. [i]

[+0] Brain structure variations of 15-20% exist across normal populations without corresponding functional impairments or harm. [i]
[+0] Correlation between social media use and brain structure does not establish causation given confounding variables like socioeconomic status. [i]

[+0] Normal adolescent synaptic pruning reduces gray matter volume by 10-20% without pathology according to established developmental trajectories. [i]
