All of us have experienced a situation in which we asked people to do something and they did it badly or did not do it at all. In such situations we thought, ‘He is stupid, he cannot do a simple thing…’
Usually it is not the lack of intelligence that causes people to perform badly or fail to perform overall. Research has shown that the most common reason for misunderstandings and badly performed tasks is a communication error.
When two people who are having a conversation and do not understand each other, the usual complaint is that they.”are not speaking the same language.” This reference to “a common language” generally means that if people are to understand each other, the same vocabulary is essential. However, this reference to a “common language” has another connotation, which is often overlooked: mutual comprehension also requires using the same system of logic, since, despite a widespread misconception, there is more than one.
