Everyone wants to choose the right thing to do. This is the original meaning of the word 'intelligence". To be 'effective' as well, you also need to use the kind of intelligence that will get the right thing actually done. Hence the name Effective Intelligence. Action research with clients, longitudinal and in depth over more than three decades, has set out to discover how people can learn to put the two together more efficiently and more frequently. This is when peak performance is achieved. It is a tried and tested route to improve thinking about things that matter to everyone.

Effective Intelligence provides a universal language that connects the Person with the Task (s)he is facing up to.  Here, a Task means any situation difficult enough to demand your best thinking.  Half the difficulty of any Task is to find what thinking activities it needs:  the other half is to supply them in the right combination.  This matching is made easy by using the same coding for the thinking activities of the task as the profile of your thinking preferences.  The coding is a language for thought, based on your thinking-intentions, known as Thunks for short.
