Once hired, people with AS may continue to have difficulty with interpersonal communications. Homelessness is very common among people with AS. Two traits sometimes found in AS individuals are mind-blindness (the inability to predict the beliefs and intentions of others) and alexithymia (the inability to identify and interpret emotional signals in oneself or others), which reduce the ability to be empathetically attuned to others. Alexithymia in AS functions as an independent variable relying on different neural networks than those implicated in theory of mind. In fact, lack of Theory of Mind in AS may be a result of a lack of information available to the mind due to the operation of the alexithymic deficit. A second issue related to alexithymia involves the inability to identify and modulate strong emotions such as sadness or anger, which leaves the individual prone to "sudden affective outbursts such as crying or rage". According to Tony Attwood, the inability to express feelings using words may also predispose the individual to use physical acts to articulate the mood and release the emotional energy. People with AS report a feeling of being detached against their will from the world around them ("on the outside looking in"). They may have difficulty finding a life partner or getting married due to poor social skills. The complexity and inconsistency of the social world can pose an extreme challenge for individuals with AS. In the UK Asperger's is covered by the Disability Discrimination Act; those with AS who get treated badly because of it may have some redress. The first case was "Hewett v Motorola 2004" (sometimes referred to as Hewitt) and the second was "Isles v Ealing Council". The same applies in the United States with the Americans with Disabilities Act, amended in 2008 to include autism spectrum disorders. The intense focus and tendency to work things out logically often grants people with AS a high level of ability in their field of interest. When these special interests coincide with a materially or socially useful task, the person with AS can lead a profitable career and a fulfilled life. The child obsessed with a specific area may succeed in employment related to that area. According to Elizabeth Fein, the dynamic of role-playing games is especially positive and attractive to people on the autism spectrum. The social information exchanged in these games are explicit, top-down and systematic and they follow a set of shared abstract rules. Baez and Rattazzi showed that interpreting the implicit social information of daily life is difficult for them. The autism rights movement is a social movement within the context of disability rights that emphasizes the concept of neurodiversity, viewing the autism spectrum as a result of natural variations in the human brain rather than a disorder to be cured.
