Creativity is always fun and highly motivating to the people involved. This sense of fun should be kept throughout CoRT 4, but at the same time creativity is a serious matter. The purpose of creativity is to arrive at an effective new idea, not to offer some bizarre gimmick.

It is unfortunate that in ordinary language the word "creativity" is often applied to artistic creativity, which involves emotional resonance, craftsmanship and many other characteristics in addition to the ability to create new ideas. In CoRT 4 the type of creativity that is developed is the 'design' type of creativity. This type of thinking Edward de Bono has called 'lateral thinking' (a word which is now officially recognised in the Oxford English Dictionary). Many of the processes put forward in CoRT 4 arise directly from the nature of lateral thinking. The processes are put forward as thinking tools which can be applied deliberately and directly in order to produce a result.
