Ways to celebrate

The "brain training" industry built itself on a shaky premise: that drilling narrow puzzle games would sharpen general intelligence. The science tells a more modest story — the sharpest gains come from learning genuinely new, effortful skills, not repeating the same app-based drill.

Pick a real skill, not just a drill

  • Start something with an actual learning curve — a new language, an instrument, or a strategy game like chess or bridge — rather than a repetitive tapping game.
  • Mix up your routine: novelty itself seems to matter more to cognitive engagement than repetition of any single task.

Know what the research actually shows

Helpful resources: The American Psychological Association's Monitor on Psychology examines the evidence — and the hype — behind commercial brain-training games in "Sharpening cognition."
