EEG revealed significant differences in brain connectivity: Brain-only participants exhibited the strongest, most distributed networks; Search Engine users showed moderate engagement; and LLM users displayed the weakest connectivity. Cognitive activity scaled down in relation to external tool use.
Over four months, LLM users consistently underperformed at neural, linguistic, and behavioral levels.


It is obvious, but we have so many liars lying to everyone and each other about AI that they get away with it. Skilled bullshitters shitting up clouds of smoke and using every manipulation tactic in the world.
Some hard evidence makes it easier to prevent their damage.
