Thinkers make decisions based on logic. They tend to see the world in black and white and can be uncomfortable in situations not easily clarified and labeled. They prefer to focus on tangible things, searching for truth, logic and clear labels such as right and wrong. They like to discover the patterns, structures and systems within a situation. At work, they are task-oriented. Working with them is often brief, succinct and business-like. They may be seen as cold and heartless by Feelers.
