There is a similar, very powerful technique for small groups meeting in the physical world, which we’ve often used to discuss contentious issues among the staff and fellows at Code for America. It’s called a “Human Spectrogram.” The group stands together in the middle of a large room. Someone makes a statement, and those who agree strongly with it move to the far end of the room. Those who disagree move to the other end of the room. People whose views are less polarized can arrange themselves anywhere in between.
