The summary
The article discusses the complex nature of multitasking, pointing out that while it may seem like doing many things at once, it’s often just “task-switching,” which can hurt productivity and focus. Lab research shows that even small task switches can cost time and reduce efficiency. In the real world, this becomes worse, as workplace interruptions can take an average of 25 minutes to recover from. However, not all multitasking is bad—doing simple tasks like doodling or listening to music can improve concentration in boring situations. The article emphasizes that multitasking in the workplace or during meetings may reveal deeper issues in team dynamics or leadership strategy. The key takeaway is to work in focused blocks of time and be aware of the hidden costs of switching tasks frequently.

1. Introduction to Multitasking
Multitasking is common, but psychologists question its effectiveness.
Some experts believe it harms productivity or is impossible.
2. Contradictory Research Findings
Negative Effects:
Driving while talking on the phone is dangerous.
Task-switching leads to mental performance drops.
Potential Benefits:
Doodling may help attention in boring lectures.

3. Understanding Task-Switching
What we call multitasking is often “rapid task-switching.”
Brain focuses on only one thing at a time.
Frequent switching has a time cost and reduces efficiency.
4. Measuring the Cost
Task-switching can take as little as 200 ms but reduces productivity.
Interruptions at work can take 25 minutes to recover from.
Multitasking costs the U.S. economy billions.
5. Real-World vs Lab Research
Lab tasks are simple, while real-life multitasking involves more complexity.
Real interruptions are more distracting than those in lab studies.
6. Practical Advice
Multitasking is harmful, especially when we don’t notice it.
Focused 30-minute work blocks are more effective.
Multitasking with easy or unconscious tasks (e.g., music during exercise) is okay.
7. Multitasking in Meetings
