Evidence mills are companies hired by educational program developers to conduct research showing their programs are effective and “evidence-based,” in order to qualify for government funding. However, critics argue these studies lack rigor, independence, and transparency, often using small sample sizes, short durations, lack of control groups, and vague measures to produce positive findings that support their clients. Proponents contend evidence mills provide useful affordable services, but there are widespread concerns about conflicts of interest and research quality. The rise of evidence mills has been linked to policies requiring so-called “evidence-based programs,” leading to high demand for studies that give interventions the appearance of being “evidence-based.”
