“The conclusion this article reaches, based on the presented arguments, is that Evolutionary Psychology (EP) may be a contribution to psychological science at several different, important levels. First, EP allows psychologists to communicate between different areas of psychological interest, and with other branches of science relevant to psychology as a life science. Second, EP provides a well-researched, rigorously formulated theory for evaluating any other psychological theory. The theory may prevent one from suggesting abilities that could not evolve but have been suggested within almost all psychological disciplines. The versatility EP shows as a theoretical framework for disciplines as different as psychoanalysis and cognitive science, suggests that EP may succeed in integrating psychological science. It also supports the claim that EP is as theoretically valid a science as cognitive science and evolutionary biology. EP also brings to psychology the focus on a theoretically rigorous and predictive theory of Human Nature, and the functional approach, which may provide maturation from the level of mere descriptive science. At the level of generating new theories and insights about Human Nature, EP seems to have proven its worth.”

Context: Psychology is a very unsatisfactory science. Comparing the vast body of systematised and recognised facts in physics with those in psychology one will doubt the advisability of teaching the latter to anybody who does not intend to become a professional psychologist, one might even doubt the advisability of training professional psychologists. But when one considers the potential contribution which psychology can make to our understanding of the universe, one's attitude may be changed. Science becomes easily divorced from life. The mathematician needs an escape from the thin air of his abstractions, beautiful as they are; the physicist wants to revel in sounds that are soft, mellow, and melodious, that seem to reveal mysteries which are hidden under the curtain of waves and atoms and mathematical equations; and even the biologist likes to enjoy the antics of his dog on Sundays unhampered by his weekday conviction that in reality they - are but chains of machine-like reflexes

Context: Our aim is to sketch the outlines of a new science which is to intermediate between the modern laboratory psychology and the problems of economics: the psychological experiment is systematically to be placed at the service of commerce and industry. So far we have only scattered beginnings of the new doctrine, only tentative efforts and disconnected attempts which have started, sometimes in economic, and sometimes in psychological, quarters. The time when an exact psychology of business life will be presented as a closed and perfected system lies very far distant. But the earlier the attention of wider circles is directed to its beginnings and to the importance and bearings of its tasks, the quicker and the more sound will be the development of this young science. What is most needed to-day at the beginning of the new movement are clear, concrete illustrations which demonstrate the possibilities of the new method. In the following pages, accordingly, it will be my aim to analyze the results of experiments which have actually been carried out, experiments belonging to many different spheres of economic life. But these detached experiments ought always at least to point to a connected whole; the single experiments will, therefore, always need a general discussion of the principles as a background. In the interest of such a wider perspective we may at first enter into some preparatory questions of theory. They may serve as an introduction which is to lead us to the actual economic life and the present achievements of experimental psychology
