There is research which shows that decisions made by a large group are more accurate than those of a small panel of experts. This is called the “Wisdom of the Crowd”. The findings state that the group must be diverse and draw upon a wide spectrum of the population with people from all walks of life.

I suspect that where the opposite is true, namely that the crowd is not diverse and instead shares a uniform and homogenized worldview, that not only does collective wisdom suffer but also the decision-making abilities of the individual within the group.

I call this the “Idiocy of the Crowd”
