This is another absurd myth, since the analysis of information will not produce new ideas. Some years ago I designed the Six Hats method. At any one moment, all parties are thinking in parallel in the same direction. This method is now rapidly being taken up by corporations such as Du Pont, IBM, NASA, Prudential, Texas Instruments, NTT, Statoil, Shell etc. Meeting times are reduced to a quarter of what they had been.
Output is far more constructive.
In a recent experiment with 300 senior public servants, the use of the hats resulted in a five-fold increase in thinking productivity. Less than ten per cent of what is taught in schools is of the slightest use to society in general or to the students involved. It is taught because it is there - and it is there because it has been there before. In effect, education is mostly expensive baby-sitting. It sets its own exams and criteria of success and is happy to satisfy these.
