The way to task is that there's a right answer and it can be conveyed between individuals. The group discussion, small group discussion, converts majority individual failure to majority group success. We recruited people to discuss the task in text. They're doing it in a chat room. And that allows us to record their individual answers before they go into the discussion,. Record every utterance they make in the conversation. Then record their answers at the end of the discussion when they come out  and see how their perception of the right answers is changed by the discussion.
