Why do we have so many meetings?

A study by the National Bureau of Economic Research found that the average worker in the US has 20 meetings per week, with 62% of those meetings being unnecessary. The study suggests that meetings are often a result of technological advancements, which have increased productivity but also led to more communication and collaboration. This has resulted in more frequent and often unnecessary meetings. The study also found that the average meeting length is 30 minutes, with 40% of meetings lasting between 15-30 minutes, and 31% lasting between 31-60 minutes.
