Among the hot-button issues of the current era is the nature of autism and the way people with this disorder should be treated. Due to the introduction of autism spectrum disorder (ASD) in the 2013 edition of the American Psychiatric Association’s Diagnostic and Statistical Manual (2013), children and adults who previously would have been diagnosed with the relatively mild Asperger’s syndrome are now considered on the autism spectrum. Furthermore, in recent years some of these individuals with milder forms of autism have embraced the autistic label and established a disability rights movement on their own behalf. One of the principles of this movement is that, although autism is a psychiatric disorder, it should not be treated with therapy or medicine like other disorders. The foremost organizational representative of this movement is the Autistic Self Advocacy Network (ASAN), whose “What We Believe” section of their website claims that autism cannot and should not be cured (Autistic Self Advocacy Network n.d.). One of the implications of this philosophy is that ASAN is opposed to the use of applied behavior analysis (ABA), the most popular and arguably the most evidence-based treatment for autism. What has resulted from this circumstance is an object lesson in how a social justice movement can contaminate the search for truth at the expense of liberty.
