Different jobs require different degrees of mental ability.
EXAMPLE 1: Most competitive jobs require the ability to meet basic
standards of neatness and cleanliness. However, the standards that must be met vary greatly depending upon whether the
job(s) being considered involve dealing with the public; or working in a factory,
a coal mine, a stock yard, etc.
EXAMPLE 2: Most competitive jobs require the ability to travel to and from work and thus, would
be precluded by extreme agoraphobia in which the person is incapable of leaving their home. However, a mild case of agoraphobia
may not preclude the ability to travel to and from work or preclude work performed
in the same (and thus, familiar) setting each day.
