quack quack: my autistic duck analogy

Whenever my husband and I talk with people about autism, or describe some of the behaviors and traits that are related to it, someone will inevitably identify with one or more of those behaviors and joke about how they must be on the spectrum too. As another logical conclusion would be that autism is an exaggerated or imagined condition, I am glad that no one I know has used their identification with an autistic trait as an opportunity to disbelieve the existence of autism! However, the situation is common enough that I’ve been searching for a good way to illustrate the difference between having one or more common autistic behaviors and actually being autistic.

An infographic from Little Black Duck (an Australian company specializing in autism communication services) uses the analogy of pregnancy: someone might have some of the symptoms that are commonly associated with pregnancy, like sore feet or nausea or weight gain, without actually being pregnant – there is a different underlying cause behind the similar or even identical presentations.


I think this is a helpful analogy for the most part, except for the fact that autism as a condition is defined by the presence and degree of certain types of behaviors. Pregnancy is very clearly distinguished from non-pregnancy by the presence of a fetus; there is no such clear-cut biological test to distinguish the autistic mind from the allistic mind. Those very human behaviors that present in both autistic and allistic individuals are the only metric used in making the diagnosis, and the line is drawn at a somewhat subjective conjunction of multiple co-occuring traits and the severity thereof.

To me, the clinical struggle of defining the autism spectrum seems similar to the zoological struggle of defining a taxonomical species. Perhaps a duck could be defined as a warm-blooded, egg-laying animal with wings, feathers, webbed feet, and a broad bill. A seagull could relate to many of these duck traits, but not having all of them would fall short of the official criteria. A bat or a snake or a duck-billed platypus could relate on a more distant level, while a moose or bear would struggle to understand the duck at all save from an external perspective.

Likewise, some people will relate to the social anxiety many autistic people struggle with; some people will identify with sensory sensitivities; others will connect with the difficulties of small talk and nonverbal communication. People with other neurodifferences, like ADHD or FAS, will probably have more behaviors in common with autistic people than the general allistic population will, but like the seagull will fall short of the official criteria for the diagnosis. On the flip side, some people will lack almost all of the autistic traits and behaviors, and struggle more to bridge the differences between them and their autistic family and colleagues. But just like ducks are still animals, and all of their characteristic traits are shared (individually or in sets) by some species or another in the animal kingdom, so too autistic people are still human, and all of their characteristic traits can be found scattered throughout the general human population. It is only when all those traits converge that a duck is defined, or autism is diagnosed.

Now I just have to wait for a conversational opportunity to use my new analogy 🙂 What do you all think? Does it make sense? How do you try to explain the difference between autism as a neurotype and commonly seen autistic behaviors?
