Two Heads Are Better Than One Views
Each trial of the experiment paired up two of 72 male participants. Over two timed intervals, the researchers used computer screens to show each of the two partners a visual field with six small circles. During one of the two intervals, one of the six circles appeared to be slightly darker than the other five. The participants each had to identify which circle was darker, and during which interval this difference occurred.
In the first section of the experiment, the partners saw identical images on their computers, made their choice, and then were given the chance to communicate before coming to a final, joint decision. By examining each participant's initial answers, the researchers could determine which of the two participants was individually better at the task. During this first set of trials, two heads were indeed better than one: the teams consistently chose the correct circle and interval more often than the more successful partner did on his own.
Blinder, Alan S. Morgan, John, 1967- Are Two Heads Better Than One? Monetary Policy by Committee Journal of Money, Credit, and Banking - Volume 37, Number 5, October 2005, pp. 798-811 The Ohio State University Press Two experiments were conducted to test the common hypothesis that groups make decisions more slowly than individuals. One of these experiments imitates real-life monetary policy decisions. In both cases, the hypothesis is found wanting: groups are not slower than individuals. In both experiments, we also find that group decisions are on average better than individual decisions. This holds regardless of whether the groups make decisions by unanimity or majority rule. Simple mechanical theories of group decisionmaking
4) Students are more effective interpersonally as a result of working cooperatively than when they work alone, competitively or individualistically. Students with cooperative experiences are more able to take the perspective of others, are more positive about taking part in controversy, have better developed interaction skills, and have a more positive expectation about working with others than students from competitive or individualistic settings.
