In 1961, approximately two years after existential psychology became a known domain of psychology, Rollo May voiced his critiques of the ever-growing field. He identified concepts that he believed would hinder the profession as it developed, he called these unconstructive trends. May identified five unconstructive trends: The idea the existential psychology could not be specialized to a particular group Existential psychology is not a form of therapy Existential psychology is not the same as Zen Buddhism The anti-scientific tendencies of existential psychiatry The widespread “wild eclecticism” would ruin modern therapy First, May disliked the idea that existential psychology could be specialized to a particular school or group, namely the Ontoanalytic Society. This society analyzed what it meant to be human, or at least they tried to, which May believed would damage existential psychology. Not only was it empirically impossible to quantify, but it was also immoral to attempt. This analysis technique rationalized individual guilt so that the individual could feel relived from whatever was troubling them; ultimately, May believed this process was removing the humility from the human experience. May's second unconstructive trend, which builds on first trend, emphasized how existential psychology is not a system of therapy. Rather it is an attitude towards human beings. Existential psychology seeks to understand the structure of human beings and their experiences. Third, May believed the association of existential psychology with Zen Buddhism downplayed the significant differences between these two practices. Existential psychology brings awareness for existential problems like anxiety, tragedy, guilt, and the reality of evil. Attempting to by-pass these problems using Zen Buddhist techniques would cause loss of sense of self and loss of confidence in capacity for free will. May believed that if we face problems head on, using existential psychology, then we make peace with them and assign them meaning. Fourth, May detested the anti-scientific tendencies of psychologists practicing existential psychiatry. Such tendencies become popular alongside America's anti-intellectualism; a time period where distrust for reason was widespread. May argued against this, stating that science is a part of the universe, therefore, we must accept it. Finally, May suggested the increase in “wild eclecticism” would ruin therapeutic practice. May believed wild eclecticism overemphasized therapeutic techniques (gimmicks) leading other existentialists to conclude that therapeutic techniques were unimportant to the therapy process. Conversely, May advocated for therapeutic techniques, as long as they held clear presuppositions, and were administered in an undogmatic manner
