Find out what you and others are like.

Because of the biases with which we are wired, our self-assessments (and our assessments of others) tend to be highly inaccurate. Psychometric assessments are much more reliable. They are important in helping explore how people think during the hiring process and throughout employment. Though psychometric assessments cannot fully replace speaking with people and looking at their backgrounds and histories, they are far more powerful than traditional interviewing and screening methods. If I had to choose between just the assessments or just traditional job interviews to get at what people are like, I would choose the assessments. Fortunately, we don’t have to make that choice.

The four main assessments we use are the Myers-Briggs Type Indicator (MBTI), the Workplace Personality Inventory, the Team Dimensions Profile, and Stratified Systems Theory. But we are constantly experimenting (for example, with the Big Five) so our mix will certainly change. Whatever the mix, they all convey people’s preferences for thinking and action. They also provide us with new attributes and terminologies that clarify and amplify those we had identified on our own. These descriptions are based on my own experiences and learnings, which are in many ways different from the official descriptions used by the assessment companies.
