Perception and Logic, For the purpose of discussion we are going to assume that most managers are reasonably logical beings. Given adequate information, they are able to assemble the facts, to make rational decisions, and to take appropriate action. This process is symolised very simply by what Edward de Bono calls a “logic bubble”. Figure 1 shows a manager's logic bubble containing P, his total perception of the circumstances with which he must cope. The line sticking out of the bubble indicates the polarity of action, i.e. the direction in which the manager has decided to move as a result of applying logic to his perceptions.
