Linguistics is the science of language. Our minds instinctively generalise, so to work efficiently the
brain categorises in an evolutionary effort to assist decision
making.
The Reticular Activating System is a part of
the brain (RAS)
that kicks in when you have focused
thoughts on something specific, and then it notices
more and more examples of the same thing. It is often unhelpful and even destructive when the
thought you
have is damaging to relationships or your
personal development.
