<P><H1>Abstract</H1><BLOCKQUOTE>
Several paradoxical effects in cognition are discussed.
One type is "evasions" -- of a thought, a perception, or a response
-- that may cause the presence of precisely what is meant to be
avoided. Another type is "lay interventions" that channel
information to mental processes that do not know how to deal with
it, often resulting in aggravation of the problem meant to be
solved by the intervention. Some psychosomatic effects may be due
to lay interventions. Paradoxical effects may stem from attempts to
bypass, or substitute for, the normal functioning of subsystems of
the mind.
