I welcome you to explore the theory and research related to personality type with the members of this interest group and association. Our goal is to continue to examine evidence and consider topics relevant to perspectives on psychological type. My proposition to you is that this area will be as exciting and interesting as you are willing to participate and contribute.

Psychological type has a long and interesting history. It is fair to say that the theory has generated many questions. While C.G.Jung was not the first to propose that patterns in the way individuals see and do things can be understood, his work certainly has capture our attention through the various tools that have been created to measure it. If we are to be true to this lineage, then we need to keep the question open as to the nature and use of psychological type.

Fortunately our complexity means that exploring human experience is a never ending journey, which I hope you will participate in by asking questions, presenting at either webinar conferences or association events. I see “theory” as a sound, working hypothesis which is based on evidence in multiple ways to test assumptions, propositions, and implications—in this case, of psychological type. And if we are going to have a vibrant community of interest, we need to share what we see, how we see it, and what new questions have emerged.


Please send your comments to me as you read articles in the Bulletin and Journal, or attend meetings and you hear something you feel is worth sharing for everyone. You can send email to, post questions or responses on the blog I’ve created at I want you to feel part of an active community of practice!!



About APTi’s Theory & Research IA Consulant:



Greg Huszczo holds his doctorate in Industrial/Organizational Psychology from Michigan State University. His main areas of expertise are in the fields of organizational change, leadership, teams, union-management relations and personalities.

Since then he has used the updated versions of the MBTI instrument and its framework in his research, teaching, leadership coaching, and OD consulting practice. He has worked with over 200 organizations as they wrestled with the complicated issues of change including some in the manufacturing sector (e.g. Ford Motor Company, Visteon, General Motors, Freightliner, Navistar, Caterpillar, La-Z-Boy, Kellogg’s, British Petroleum); in the service sector (e.g. Australian Postal System, Metropolitan Airport Authority, VA Patient Safety Center plus several hospitals, city administrations, universities, and school systems); for unions (e.g. UAW, USW, AFSCME, SEIU, UA); and for institutes (e.g. National Coalition for Community and Justice, Society of Manufacturing Engineers, Facility Management Institute, and several Labor-Management Associations).

Greg has presented at ten APT international conferences and many regional and local chapters as well.  He also serves as the Chairperson of the Theory and Research Interest Group of APTi.  Greg has written over 60 peer reviewed articles and papers and four books: (Toward a More Organizationally Effective Training Strategy and Practice, Prentice-Hall/Reston Business Book Division, 1986; Tools for Team Effectiveness, Nicholas Brealey Publishing, 1996, 2010; Tools for Team Leadership, Nicholas Brealey Publishing, 2004, 2010) and his latest book, Making a Difference by Being Yourself (Nicholas Brealey Publishing, 2009, 2010), which show you how to use your personality to make a difference at work and in your relationships.
