Why Multitasking Feels Efficient

Why Multitasking Feels Efficient
but Reduces Performance

Multitasking feels productive. Handling many things at once gives a sense of control.

But science shows that the brain does not truly multitask. It switches.

1. The Brain Pays a Switching Cost

Every time attention moves from one task to another, the brain needs time to reorient.

This hidden delay is called attention switching cost.

2. Cognitive Load Increases Quickly

Each task consumes mental resources.

Multiple tasks pile up, causing faster mental fatigue and more mistakes.

3. Efficiency Is an Illusion

Multitasking feels fast because activity never stops.

But actual progress slows, and quality quietly declines.

4. Single Focus Uses Less Energy

When attention stays on one task, the brain enters a stable rhythm.

This state produces better results with less effort.

Final Conclusion

Multitasking is not a skill problem. It is a biological limitation.

Doing one thing at a time is not slower — it is more efficient.
