Evidence-Based Practice as a Driver of Pseudoscience in Prevention Research

Many of the subject matters discussed under the topic of pseudoscience can be readily distinguished from science proper, and there are few individuals with any serious scientific training who would mistake these for science-based disciplines. Harder to identify and distinguish are those disciplines that may have begun as a genuine science but have transformed into pseudosciences primarily through their pursuit of positive results. This chapter discusses one such example, drug prevention research, and contends that the adoption of so-called “evidence-based practice” by this field of study has been a key driver of its decent into pseudoscience. It discusses this process using a systems approach and focusses specifically on two negative feedback loops, one entailing flexible data analysis and selective reporting and one entailing minimal adherence to study design criteria. These lops are illustrated using examples of prevention and treatment programs that have been deemed “model” intervention by the National Registry of Evidence-based Programs and Practices (NREPP).
