Empathy is a controversial subject in the field of Asperger Syndrome/neurotypical relationships. The theory of mind postulates that people with Asperger Syndrome have some degree of mind blindness, or an inability to fathom the motivations and feelings of others. Aspies don’t seem to read the social clues that tell NTs (neurotypicals) what is going on.
For example, Aspies are notoriously poor at recognizing complex emotions in others. They struggle to understand that someone may be stretching the truth for emphasis or as the punch line to a joke. They are confused by irony, pretense, metaphor, deception, faux pas, white lies and so forth. This is why NTs find Aspies to be clueless in social situations and why there are all types of curricula on the subject of teaching Aspies how to navigate the social world.
