Thinker Personality Style


Those with the Thinker (NT-Green) personality style tend to be mentally active, constantly questioning and pondering.

Thinkers enjoy discovering the information behind the information and may know a little bit (or a great deal) about just about everything. They rely on their logic, time to think, and investigation of the facts to make decisions.

Thinkers are motivated by endeavors that increase knowledge and competence. They enjoy control over their own direction and seek intellectually interesting work.

Thinkers have an innate drive to decipher life’s mysteries.

The most important thing is to not stop questioning.

-Albert Einstein

Their disdain for herd mentality along with their tenacity to improve systems, ideas, methods, technology (well just about anything) compels them to investigate new solutions and a quest for never-ending developments.

They prefer to work independently when possible and approach decision-making by gathering data and investigating the best strategy for success

It is not worth an intelligent man’s time to be in the majority. By definition, there are already enough people to do that.

-G.H. Hardy


As naturally abstract thinkers, this temperament style finds it easy to understand theoretical material. They are adept at remembering and explaining the data and knowledge they unearth in their research.

Thinker Internal Compass

Thinkers may spend a great deal of time lost in their thoughts and ideas and often derive great pleasure from doing so. They can hardly resist fixing, solving, or figuring out an intellectual challenge, especially when someone says it cannot be done.

Thinkers like to devise systems for daily living to free their brain up for more important matters. They usually don’t look to material possessions for happiness in life. Instead, their motivational fires are fueled by learning, imagination, and invention.

Thinker Frustrations

Putting elements together to create a bigger picture or vision, they often pick up on things others may overlook. Thinkers believe they are doing others a favor to point out discrepancies and imperfections. Often driven to find the exception to the rule and envision future ramifications, at times they can be baffled when others do not “get it” or fail to notice something that is so blatantly obvious to them.

Thinkers get annoyed with other’s stupidity or inability to think outside-the-box.

People think it must be fun to be a super genius, but they don’t realize how hard it is to put up with all the idiots in the world.

-Bill Watterson

Core Value: Competency

Thinkers seek to express themselves through their ability to be competent in everything they do. Before they make a decision or take an action, they stop to think, “Do I have all the information, have I researched all the data required to draw a sound conclusion, am I competent to respond to this?”

The last thing they would want to do is to “look stupid”, especially in front of others they respect or care about.

The terms used to describe the Thinker style are plentiful (as you can see by the graphic at the top of this page). We at Personality Lingo strive to bridge the gap in understanding of terms so personality enthusiasts and those they teach can recognize the various differences and commonalities between systems. To get you started, the following is some nomenclature associated with the Thinker Style.

The term, Choleric, originating from Galen and brought to Waldorf schools by Rudolf Steiner roughly correlates with the Thinker style. Old school Keirsey/Bates fans use Promethean to describe this style, while the present Keirsey devotees refer to Thinkers as Rationals or NTs. The most frequently used term by color enthusiasts, such as admirers of Don Lowry’s True Colors model is Green. Personality Dimensions, Color Lingo, and Real Colors also use Green to describe this personality style. Similarly the color Green is used to represent the Thinker personality style in the Spectrum Temperament and Insight Learning models. The MBTI personality inventory subdivides the Thinker style into four personality types: INTJ, ENTJ, INTP, and ENTP.
