Not all people can adequately assess their ability in mathematics. To such conclusion scientists from America and Germany during the experiment. Volunteers were proposed to pass a test that provides an accurate assessment of the level of mathematical abilities. Before the study, people had to give a subjective assessment of their own skills.
The volunteers underwent three tests: the task, which evaluates basic knowledge (to calculate, what is the percentage of the number), subjective assessment of mathematical abilities. In the third test people had to compare the direct point and a specified number.
Scientists have found that in most cases people gave incorrect assessment of their knowledge of mathematics. Someone had pinned great hopes on our own strength, but without much problems solved equations in mind. "Potential" of mathematics as often could not solve simple verbal task.
