Thinkers keep their desks between themselves and their guests and their office seating implies formality and non contact. Conversationally, you can spot Thinkers easily by their slow pace and attention to accuracy. Ask a Director what time it is and you will be told the day of the week. Conversationally, Thinkers want to know and want to tell virtually every facet of a story. They speak relatively slowly and deliberately, pausing, if necessary without self-consciousness to search for the right word.
Thinkers derive joy from speaking precisely and accurately.
Thinkers are time-disciplined, so be sensitive to their time. They need details, so give them data. They are task-oriented, so don't expect to become their friend before doing business or working with them. That may develop later, but unlike Socializers it is not a prerequisite for Thinkers. Support Thinkers in their organized, thoughtful approach to problems and tasks.
