One study found that the animals associated in large groups make better decisions than smaller ones. Through an experiment to observe fish researchers realized that the fish avoided the predator solitary in a little over half of the trials. The higher the group, the proportion of fish that chose the right path increased, reaching almost 90%.
Although this has always been an assumption, there are few empirical demonstrations of the phenomenon. This experiment proves that the speed and accuracy decision making is greatly increased in proportion to the size of a school group, so the researchers reached two conclusions: The first is that the groups are led by a small proportion of good decision-makers. The second, that members of a group operating under the self-monitoring and are in a constant state of alert. Thus, the efficiency of decision making of schools lies in the division of labor and the smooth exchange of information.
The authors argue that this act of association and cooperation may have helped to promote the evolution of social communities in animals, from small, like ants to human beings themselves.
What do you think of this statement? "Human beings are more efficient in making decisions when we do as a team? What conditions have to give a team to work collaboratively and get successful results?
debate remains open for discussion.
