Milton's interest in autism began when his son was diagnosed as autistic in 2005 at two years old. Milton himself was diagnosed with Asperger syndrome in 2009 at the age of 36.[3]: 13 [4]
Milton is best known for his "double empathy problem" theory first published in 2012,[5][6][7] which is the idea that, contrary to what previous studies in the late 20th century had concluded, autistic people are not inherently deficient in empathy but rather that autistic and non-autistic people bidirectionally struggle with empathy and communicating with one another.[8][9][10] While the concept had existed in earlier discourse, dating back to arguments voiced by activists like Jim Sinclair since the 1990s, Milton named and significantly expanded on it.[3]: 10 [10]
Milton has co-authored over 250 publications[2] related to autism. His work is influenced by the social model of disability,[3]: 10–12 [7] and many of his publications deconstruct and critically analyse past theories. For example, he has argued that self-stimulatory behavior (stimming) should be viewed positively and may help autistic people achieve flow states.[11] His work has been favourably received by the academic[9][10][12] as well as the autistic community.[6][13]
He has spoken out against the Spectrum 10K project, questioning whether it truly was contributing to the well-being of autistic people.[14]
