There Are Indeed More Left-Handers Within the Autism Spectrum Disorder Compared with in the General Population, but the Many Mixed-Handers Is the More Interesting Finding
Letter to the editor in response to Howard Kushner’s claims that our data on non-right-handedness within the autism spectrum disorder were organized, by sleight of hand, so they would give a significant result that would support our desired conclusion. Here, we have re-categorized our data, and present evidence that there are indeed more left-handers within the ASD. Furthermore, we refute claims that we have misinterpreted our results in order to conclude about a causal link between left-handedness and ASD, and highlight our original suggestion that mixed-handedness, more specifically unclear handedness, is the bigger problem, and that our findings of a total 60% non-right-handedness was the more interesting finding.
