The Science of Personality


The Foundation of Hogan

Hogan was founded by Dr's. Robert and Joyce Hogan after more than 15-years of accumulating evidence to prove that personality testing predicts job performance. The Hogans' collective work in personality measurement is as distinctive as it is theory-based. The Hogans are widely credited with demonstrating how personality factors influence organisational effectiveness. Today, we continue to build our position as the innovative leader in providing scientifically-based personality assessment solutions for business and industry.

Mark Williams

Senior Coach, Port Adelaide Football Club

Hogan has proven to be a brilliant tool in helping our players and staff understand themselves, each other and most importantly, how to help each other to enhance performance at our club.
The individual and group profiling was right on the money. I encourage all sporting groups and business’ that pursue excellence to give them a call ...you too will become a believer.

Alan Church

VP organisational Development, PepsiCo

We conducted a study involving more than 350 PepsiCo leaders. Our results provided strong empirical support for the value of the Hogan process in developing leaders. Furthermore, a significant majority of the participants advocated the use of the process for their own development.

Kimberly S. Scott, PhD

Director, MS in Learning & organisational Change Northwestern University

The Hogan Leadership Series is an important part of our students’ developmental experiences while in our Master’s program. The insights that they gain from these assessments of their strengths, values and challenges is powerful input for the individual learning plan each student is required to create. This plan, in turn, forms the blueprint that the student will use to practice leadership skills while in our program and, more importantly, to become a more effective leader in the workplace.

James M. Fico, Ph.D.

Consulting Psychologist

Just a brief commemoration. The June 1994 American Psychologist article on leadership that you wrote arrived in my office on the same day that I was told by a customer that I needed to find something better than the CPI that I was using at the time. Gave you a call, and things have improved ever since. Doesn’t seem like 15 years. Thanks for all the opportunities I would never have seen without both of you. Maybe more importantly, I am realizing why I got into this business. I was a chemistry major, realizing that even as I was learning about the nature of things, it was not as interesting as learning about the nature of people. I was fully willing to admit that I did not understand people, their motives, habits, etc. That’s why every time I look at the scores on one of your instruments it is with a sense of wonder that I have an understanding of people’s most enduring qualities. That’s been a big part of the magic I have enjoyed with you.

Adrian Furnham

Professor of Psychology, University College London

Hogan provides in-depth information which, in my opinion, is the world’s leading psychometric assessment. The Challenge Report offers participants critical information that is unique to Hogan. No other assessment organisation has the resources to provide this information. Utilising these assessments is a wonderful opportunity for participants to experience, first hand, the power of these tools in selecting and coaching top talent.
