Appearance and Inference

At The Conversation, psychologist Scott Lilienfeld writes that autism creates cognitive traps for observers.  For instance, the signs appear around the time that kids start getting vaccines, so people wrongly assume cause and effect.
And many fad treatments for autism are surely born of desperation. There are no known cures for the condition. It’s not surprising that most parents of children with autism simultaneously seek out four to six different treatments for their children. Nor it is surprising that this field has been remarkably fertile ground for ostensible quick fixes, such as facilitated communication.
And some probably fall victim to a diabolical illusion. A number of the behavioral problems associated with autism, such as inattention and anger, often wax and wane over brief periods of time. If a natural – and unrelated – downtick in symptoms happens during or after therapy is delivered, parents and teachers may then conclude that the treatment brought the improvement, even though the decline in symptoms would probably have occurred anyway.
Appearance shapes how we view autism. Children with autism do not have the distinctive facial markers of, say, children with Down Syndrome or fetal alcohol syndrome. That fact might lead some to assume that individuals with autism are cognitively and emotionally normal individuals trapped inside a malfunctioning body. If that is so, all that is presumably required is an intervention, such as facilitated communication, to unlock their unrealized mental potential.
The popularity of autism fads imparts two sobering lessons. First, we can all be misled by the raw data of our sensory impressions. Virtually all autism misconceptions stem largely from what psychologists call naïve realism, the error of placing uncritical trust in our unfiltered observations. Second, scientists need to play a more active role in combating false information about autism and other mental disorders.
When researchers conduct studies that dispel the alleged dangers of vaccines or the alleged effectiveness of pseudoscientific treatments, they may assume that their job is done. That’s not the case. The legacy of autism fads suggests that their real work may have only just begun.
