well, any reader of the Hitchhiker's Guide to the Galaxy has a clue to the
answer.  Attention is hindered by the presence of a Somebody Else's
Problem (SEP) field.  When one of these is emitted, the issue is treated by
all present as somebody else's problem, and is ignored.  This is used by
certain alien species to escape unnoticed as they visit Earth.  Attention,
coversely, must be related to the lack of such a field.
