Very often in the popular literature of psychology can be found the notion of "collective intelligence". It is believed that the connection to the collective wisdom, can sometimes find answers to questions that arise in life. Many investing in the concept of collective intelligence is something fantastic, supernatural. But let's go down to the ground and look at it from those things that everyone would use in their lives, everyone has those psychological beliefs that are unique to him. More info: RBH Group. However, these beliefs constitute a kind of "foundation of human life." Or, as is called, the "mental map". It is widely known phrase "card – not the territory." It means that our understanding of the world will always contain an error that explains the specific perception of the world. In general, the mental map is always something to help, but what's the limit.

Most mental maps are outside of human consciousness, and therefore very difficult to change them enough. And what happens when people gather in a group? There is a certain combination of them. Those convictions of man who is not currently work, ie for some reason have not been effective, temporarily replaced by more efficient, if any, someone from the group. Inaccurate mental maps become less. Therefore, it is considered that sometimes training is not effectively on an individual basis, namely in the group. In addition to the above, it is clear that every single team member has their own individual experience, knowledge and skills that he can share.
