It is possible that psychologically speaking, that anything outside the
norm, is in a view, broken. And it is quite reasonable to state that
not just grandmastership, but those that so destroy the norm that they
stand by themselves, are broken. In any of the mental fields.

They may be useful, they may have desired qualities, but often this
leaks out in other more well known disorders. OCD, Paranoia,
Maniacism, schizophrenia, suicide. From computer programmers,
philosophers, artists, musicians, and chess players.

Chess has an interesting attribute in that paranoia is a useful trait to
playing well. This enhanced paranoia can be seen in many of the world
champions, and even the chess organizations, and the people that run
them. This paranoia has led to people historically attacking the game
and the players, and caused the players to be wary of others.

As one of the more "normal", it is often impossible to understand the
talented and broken other than appreciate their output. And if
anything it should remind everyone, that the mind is a very interesting
and incredible thing.
