In this interview, Ellis acknowledges that irrational beliefs have a higher biological basis than rational beliefs and that they are not at opposite ends of the same continuum. Ellis agrees that irrational beliefs are more involved in mental health problems while rational beliefs contribute to the psychology of success. The strength of conviction in both rational and irrational beliefs including self-acceptance and self-downing is explored. Ellis equates the conviction with which rational beliefs need to be held to influence emotions and behaviors with “faith.” He acknowledges the importance of faith built on facts rather than religiosity. Ellis agrees that ridding strongly motivated individuals of self-depreciation may lead to a decrease in their high frustration tolerance and, ultimately, their drive for and achievement of success. Ellis supports adding an “F” to the ABCDE model—forcefully agreeing with and applying new rational beliefs. Ellis discusses the need to develop a literature on therapeutic techniques and methods for helping people to apply rational beliefs more strongly to different areas of their lives. Ellis highlights the perils of self-efficacy positive psychology interventions if people’s innate tendency towards self-depreciation is ignored. The interviewer concludes the interview expressing the view that if we listen to Ellis, “we” need to re-think the ways we teach people of all ages to think rationally knowing that the rational re-statement of previously disputed irrational beliefs is only one of many different teaching methods.
