This apparent social indifference was viewed as central to the condition. Unfortunately, the theory also seemed to imply that autistic people are uncaring because they don’t easily recognize that other people exist as intentional agents who can be loved, thwarted or hurt. But while the Sally-Anne experiment shows that autistic people have difficulty knowing that other people have different perspectives—what researchers call cognitive empathy or “theory of mind”—it doesn’t show that they don’t care when someone is hurt or feeling pain, whether emotional or physical. In terms of caring—technically called affective empathy—autistic people aren’t necessarily impaired.
Sadly, however, the two different kinds of empathy are combined in one English word. And so, since the 1980s, this idea that autistic people “lack empathy” has taken hold.
