Personality Tests: Science or Witchcraft?

Morning Metrics

Personality tests: Are they science or witchcraft?

The mystical Sorting Hat of Hogwarts is an amazing tool: It instantly sees the student’s inner personality, and allows them to be placed straightaway in the house that suits them best. Wouldn’t it be great if we somehow had the same tool in our business?

I’m Jacob, a psychology postgrad, and I’ll soon be embarking on the road to becoming a chartered occupational psychologist. I’m no master of psychometrics, but I’ve spent the last year really getting to know them, and I’m writing a series to bridge a knowledge gap. Whether you are totally new to psychometric testing, or somewhat familiar and would like to learn more, I hope this will be the place for you – whether it’s just for personal interest, for your studies, or your career.

And on the other hand, if you are a psychometric expert I would love to hear from you as well. All comments and discussion are welcome, especially if they challenge my way of thinking and/or contribute to the wider community’s understanding.

In the coming weeks, I’ll be delving into particular tools in the psychometric toolkit, like the MBTI (Myers-Briggs Type Indicator), EQi 2.0 (Emotional intelligence Quotient), Belbin team roles: Where they came from, what their unique and nifty features are, and how they might be useful to you and your business specifically. But for this first instalment, I thought it might be good to look at psychometrics in general: What they are, why you should be using them, and how to tell if they are worth using.

If you’re already clued up on psychometrics and want to read more about the different tests, please do check back later as I begin to cover the most popular psychometrics used in business today through to the more obscure ones. I will start with the MBTI, one of the most widely used personality tools (and also one of the most controversial!).
