School of Thinking invented the idea of ‘Thinking Instructors’.
The idea being that one can become a much better thinker if one has a thinking instructor, coach or teacher.
Today, after four decades, there are over 9 million teachers of thinking skills around the world, mostly in education and in business.
SOT is the world’s first school to develop a pedagogy for teaching metacognition – not only the teaching of thinking skills but also the teaching of teaching of thinking skills. Thinking instructors.
SOT’s practical application was the Learn-To-Think Project launched in New York in 1980.

SOT is science-based. It is a curated experience for real thinkers or for those individuals who are interested in becoming highly skilled thinkers, regardless of ability or preference. Is is also for teachers of thinking skills.
____________________
Some of the different types of thinkers who have been welcome in the School of Thinking are listed to show the plurality of SOT membership:
– The instructor
– The logician
– The analyst
– The information compiler
– The idea generator
– The lateral thinker
– The detective
– The researcher
– The synthesiser
– The evaluator
– The critic
– The describer
– The clarifier
– The explainer
– The communicator
– The sales person
– The diplomat
– The header
– The doer
– The observer
– The problem solver
– The problem finder
– The designer
– The explorer
– The organiser
– The system designer
– The group organiser
There is an obvious difference between the researcher who likes to ferret out information in a defined area and the diplomat who is sensitive to changes in people and situations.
There is an obvious difference between the critic who looks at what is and the lateral thinker who looks at what might be.
There is an obvious difference between the problem solver and the problem finder.
It is not just a matter of being better at one type than another–it is a matter of enjoyment.
Which types of thinking do you enjoy most?

The book launched the Learn-To-Think Project in the US with the published mission: to train 300,000 Thinking Instructors to teach thinking skills in the USA.

In 1982, Michael and Edward co-authored this book which became a cover story on all global editions of Readers Digest (at that time, 1983, the world’s highest-circulation magazine with 68 million readers) and SOT launched the biggest thought-leadership program in the world for the teaching of teachers-of-thinking.
The innovative Learn-To-Think educational project received wide media attention in The New York Times, The Wall Street Journal, The Los Angeles Times, USAir Magazine and many print, radio and TV media banners across the USA and around the world.
Today, after four decades, there are over over 9 million teachers of thinking skills around the world, mostly in education and in business.
Thinking Lessons
Since metrics are important, too, we can ask these two questions:
Q. In 2024, how many thinking lessons given worldwide by thinking instructors, is the legacy of the School of Thinking?
A. When a class of 10 students attends a thinking lesson given by a thinking instructor, coach or teacher then that is ten lessons given. If a thinking instructor gives the class two lessons a week then that is around 1000+ thinking lessons a year, per thinking instructor. Multiply that by 9+ million thinking instructors in 2024 for a total of around 9 billion thinking lessons that year. Due to lessons given on other media, this may be a low number.
Q. What is the Value of a Thinking Lesson?
A. Because of neuroplasticity, the human brain is changed by circumstances. The brain before a thinking lesson is not the same brain after the lesson. Multiply this by a course of ten thinking lessons and the brain has been changed by the real change in circumstances. This applies to all the different changes in environment that a brain ever encounters.
We have a great deal of evidence showing how student’s brains have been changed by SOT lessons over the years and around the world. We get a lot of feedback and comments attesting to this.
When we ask students to dollarise the value of their thinking lessons (eg $1, $10, $100 etc) we have received feedback from “tens of thousands” to zero. But, most say between $10 and $100. If we take the low number we can value 9 billion lessons @ $10 to equal $90 billion+.
Such is the legacy of the School of Thinking in 2024.
