Close to 1 billion meetings take place each day around the world. CEOs spend nearly three-quarters of their workdays in meetings. Planning for and spearheading meetings eats up the lion’s share of managers’ time. In much of the industrialized world, meetings are both the metronomes and menaces of people’s working lives.

Given the enormous time spent in workplace meetings, do we know what they accomplish or how to make them as worthwhile as possible? For decades, the answer was… not really. Meetings weren’t a particularly accessible subject of study. But that has changed. Once a tiny niche area, “meeting science” is a growing specialization among organizational and social psychologists. The field is accelerating as archived virtual meetings provide vast swaths of data. And it is providing a fascinating window into human behavior.
