The Switching Cost

Attention Residue

When you switch from Task A to Task B, your brain doesn't move instantly. A "residue" of Task A stays in your RAM, slowing down your processing speed for Task B.

The 20% Penalty

Multitasking can reduce your effective IQ by up to 10 points—similar to losing a full night of sleep.

Inefficient Allocation (Conflict)
