Your Thinking Style

Your thinking style - - how you gather and process information, how you use that information to make and act on decisions, even what kind of information you gravitate towards - - influences every action. It is the basic mental model that you use to explain the world, yourself, and others. If you understand thinking styles - - your own and others - - you can then understand how to make the most of your interactions. For that reason, the InQ and its related learning materials are ideally suited for a wide variety of performance-improvement activities. Understanding how people think is essential, especially for developing activities that improve leadership, team building, negotiation skills, conflict management, problem solving, planning, communications, sales, and decision making.

The InQ's Reliability

Validity and Reliability

The InQ has been tested vigorously for validity and reliability (see “An Investigation of Item Characteristics, Reliability and Validity of the Inquiry Mode Questionnaire,” in Educational and Psychological Measurement, 1983, Vol. 43).

New Research

We encourage researchers and doctoral students to use the InQ in their research. We can offer a special researchers’ discount on our materials. If you are interested, send a letter to us outlining the purpose and design of your project.


If you are already using other tests, such as Myers-Briggs, then our family of learning materials will add a new and necessary dimension — people’s preferred thinking styles — to the information generated by those tools. There are correlations between certain parts of the Myers-Briggs and the InQ.


We invite your comments on your experiences with our learning materials — what you liked best and least, and your suggestions for improving both the content and how they are presented. Each time we reprint our supplies, we incorporate these improvements as best we can.

Client Testimonial

I have used the INQ - Thinking Styles Inventory for many years in my work with Boards of Directors and Executive Teams. Of course, when Boards and Executives come together they spend many hours thinking together, so being able to understand the strengths of the different styles and how to both respect and adapt to the different styles has led to much improved team effectiveness and individual executive effectiveness with their staff and others. I have used this in our executive development programs and also with my own executive teams. I keep a table of my direct report thinking styles by my phone so I can adjust my approach as I pick up the phone or leave my office to talk with them. A powerful tool personally, and also allows for a common language that makes it 'safe' in meetings to label overuse of a particular thinking style to the detriment of the group and get us back on track!
