Technology & tools/Exploratory

AI changes where critical thinking happens

Knowledge workers reported that AI shifts critical thinking toward verification, integration, and task stewardship; greater confidence in AI predicted less reported critical scrutiny.

Caveat. This is self-reported survey evidence, not a causal test of whether AI use reduces cognitive ability.

Technology & tools/Synthesis

A nearby smartphone may not cause brain drain

Across available experiments, a smartphone’s mere presence had no meaningful average effect on cognitive outcomes—challenging a popular productivity claim.

Caveat. This addresses physical proximity, not notifications, active use, compulsive checking, or sleep disruption.

Methodology

Useful evidence, with the uncertainty intact.

What this is

  • Peer-reviewed research translated for everyday knowledge work.
  • Clear on study design, sample, effect size, and limits.
  • Practical ideas separated from what a paper directly proves.

What this is not

  • Medical advice, a supplement guide, or a replacement for care.
  • An exhaustive academic database or a feed of every new paper.
  • A reason to generalize a small study beyond its actual scope.
