Since the inception of their profession, genetic counselors have helped patients and families adapt to varied circumstances and make decisions influenced by powerful emotions. In doing so, they have had to reconcile ethical principles with the diverse values of their patients. While this challenge is not unique in medicine, it has preoccupied genetic counselors disproportionately because such a large share of genetic counseling work involves nuanced discussions about reproductive choices and the impact of difference and disability on people's lives. Historically, the profession of genetic counseling has relied on 'nondirectiveness' to guide practice. Nondirectiveness has been defined in various ways: as a counseling method designed to be value-neutral (Caplan, 1993); as the prevention of coercion or persuasion in genetic counseling(Hamby & Biesecker, 2000); as a commitment not to impose one's own values on patients (Fine, 1993); and as a counseling strategy that supports autonomous decision-making (Bartels, LeRoy, McCarthy, & Caplan, 1997). The original ethical justification for practicing nondirectively was to respect individual patient autonomy, construed largely as non-interference in patient decision-making (Stern, 2009). This ethos grew out of a genuine respect for persons, particularly concerning reproductive choice and disability rights. The profession's emphasis on nondirectiveness has also been understood as an effort to distance genetic counseling from the morally fraught history of eugenics (Resta, 1997).
