Groups make better self interested decisions.

This is confirmed by the process used to judge Olympic and NCAA diving. Judging diving is a subjective process. Actual scores are not important; consistency is very important. So if a judge consistently judges low, it doesn't matter to the diver.

To eliminate favoritism and mathematical fairness, a diver's overall score for an individual dive is calculated in the following way:

Each of the seven judges awards a score to a diver for his or her dive. (Ex: 6-5-5-5-5-5-4) The two highest and two lowest scores are eliminated. (Ex: 6 and 4 and two of the 5s are eliminated.) The remaining scores are totaled. (Ex: 5 + 5 + 5 = 15) This total (15) is then multiplied by the predetermined degree of difficulty rating associated with the particular dive performed to calculate the overall score. These degree of difficulty ratings range between 1.2 to 4.1, in one-tenth increments. (Ex: 15 × 2.0 = 30)

So groupthink generally works if outliers are eliminated.

    It is interesting that the end result comes from the elimination of the highest and the lowest. The highs and the lows always have some sort of strange relation… like two sides of a coat before it is zipped up. It is the highest and the lowest that wrap around the others, like a coat to keep them warm. But then we take the coat off. What would the world be without the highs and lows… the bums and the sky tasters. The cement crawlers and cloud walkers.

    “Groups make better self interested decisions.”

    Maybe a self can only exist on the highest and lowest and not in a group. Maybe it is the ones that are eliminated that help us define what a self is. Small steps, small decisions, it is in the smallest things where larger things happen and become great changing exploding things.

    Dripping facets. Rolling marbles. Tumbling snow balls building up steam and speed. What will happen next? Decisions.
