In principle, groups can be very efficient when there is a culture of quick and visible agreement, like in the British Parliament when someone makes a statement and others yell, “hear, hear!” On the other hand, groups can be very inefficient when there is a culture of making points over and over in different ways with different nuances with additional tidbits of information.
Further, in group settings we are often quick to find fault and air concerns, a method of group critique that we often assume will result in a better end product. It is refreshing when critical comments get balanced with positive, encouraging shows of support.
Practical Tip: When someone says something you agree with, show it instantly with a “hear, hear” or at least a head nod. It is very useful for the whole group to see such cues. If your general view is expressed by someone else, restrain your need to present the view in a different way with a different spin with a few extra tidbits of information.
Encourage your group to adopt a “hear, hear” culture where members readily show their opinions to the whole group. Saying “hear, hear” is one way but variations include thumb signals, keypad voting, and standing line ups.
Instant, positive feedback. Hear hear!
