Simon sheds light on the positive aspect of our bounded rationality from a biological analogy, in which, because of our bounded rationality, and because we can therefore greatly enhance our limited knowledge and skill by accepting information and advice from the social groups to which we belong, individuals who are docile Ewho tend to accept such information and advice Ehave a great advantage in fitness. The altruistic individual will be fitter than non-docile individual, enabling the former to more increase its capabilities for specialisation and division of work, to finally adjust themselves to achieve the desired purpose. It may be true that the altruism is an important factor in the efficacy of organizations and institutions. However, how many trials and errors will it need for us to evolve or have mutations to be so docile or altruistic? This book gives us a great hint.
