He pointed out that the manager's own behaviour would be largely determined by the particular beliefs that he subscribed to .... McGregor hoped that his book would lead managers to investigate the two sets of beliefs, invent others, test out the assumptions underlying them, and develop managerial strategies that made sense in terms of those tested views of reality.

His hope was that the theory would lead to new insights and experiments that would lead ultimately to an acceptable one ; his aim was not to set out a deterministic, mechanical viewpoint, but rather to show that it was possible to attribute properties to an underlying reality, in contrast to the conventional approach to quantum mechanics.
