Oh, boy! While I accept on faith that these essay images could be exactly what was described, I wonder why they didn't include the so-called elven-featured children, dedicated scientists, successful researchers or able doctors, and, yes, loving parents with ASDs? Where is the apparent lack of socializing found in many spectrumites? These few selected images show engaged, smiling individuals; every one. None of the friends with ASD who I know would likely be so comfortable and happy in front of a strange journalist with a camera, but I guess it could happen.
I believe that the truth might come from the subtitle of the image essay itself when it states that "[t]o mark Autism Awareness Day, young people with special needs in Ballarat remind people to see the person, not the disability[,]" emphasis mine. That description is very likely true. It claims that several "young people with special needs" (while not confirming that they have ASD ... at least without additional disorders), were photographed as a way "to mark Autism Awareness Day[.]" It didn't state that the photographed individuals actually, really, truly have ASDs. The nuance of the subtitle might belie its claim.
Too many times, an editor assigns such an essay to a photojournalist who merely searches through his or her file-photo archives for images which have little to do with, but approximate generally, the desired result. I wouldn't be surprised if that happened here. And, "nobody will notice the difference."
