Psychological investigations are supposed to deal with the behavior of animals, including of course, the human being. They are supposed to deal with the broad, general problem of how and why we behave the way we do.

Most psychologists however, are still dealing with their particular science from the strictly biological point of view, and overlooking by and large, the ever gradual development of psychology into a social rather than biological science. Nevertheless, important methodological contributions are being made. These contributions show a progressive awareness of the societal influences to which Psychology is particularly susceptible. The problems dealt with and the way in which they are handled, reflect conditions in the everyday world. Even the experimenter in an ivory laboratory but reflects the current and wholly erroneous viewpoint fostered by interested groups, that science must be impartial and oblivious to human suffering and human welfare.
