Practice builds narrow task mastery

Decades of cognitive research show that practicing a specific mental game makes you better at that game. However, that improvement rarely spills over into general problem-solving or everyday intelligence.

The claim

Skills rarely transfer across domains

Psychological studies consistently demonstrate narrow transfer. Mastering memory techniques for numbers leaves your ability to recall names or spatial locations entirely unchanged.

How transfer fails

Training mostly improves the test itself

Large trials comparing brain games against simple internet browsing show no broad cognitive gains. Participants simply adapt to the specific speed and mechanics of the trained tasks.

The evidence

What would prove real cognitive gain

Disproving this requires rigorous trials showing lasting improvements in untaught, everyday tasks. Until far transfer is clearly demonstrated, claims of general mental enhancement remain unsupported.

What to watch

Idea

Brain Training Does Not Make You Smarter

Practicing a specific mental task improves performance on that task, not overall intelligence.
