This six thinking hats
• Yellow hat – Positive Judgment: Participants
identify benefits associated with an idea or issue.
This is the opposite of black hat thinking and
looks for the reasons in favor of something. This
is still a matter of judgment; it is an analytical
process, not just blind optimism. One is looking
to create justified statements in favor. It is
encapsulated in the idea of "undecided positive"
(whereas the black hat would be skeptical undecided negative). The outputs may be
statements of the benefits that could be created
with a given idea, or positive statements about
the likelihood of achieving it or identifying the
key supports available that will benefit this
course of action
• Green Hat: Creative Thinking: This is the hat of
thinking new thoughts. It is based around the
idea of provocation and thinking for the sake of
identifying new possibilities. Things are said for
the sake of seeing what they might mean, rather
than to form a judgment. This is often carried
out on black hat statements in order to identify
how to get past the barriers or failings identified
there (green on black thinking). Because green
hat thinking covers the full spectrum of
creativity, it can take many forms.
