Myers-Briggs is the “world’s most widely used personality test” and “the gold standard of psychological assessments”, says a Washington Post article. The article mentions government agencies and corporations that use the test, but then goes on to say that “the test is highly questioned by the scientific community” and that it’s not clear organizations should use it anymore.
Why not use a personality test in organizations? It’s a good way to find out about character traits and behavioral tendencies that might be relevant to improve training programs and group interactions. It’s also part of “talent management”, which includes “everything an organization does to recruit, retain, develop, reward and make people perform” (wikipedia). So what if it’s a money-maker, part of the $50 billion training industry – does that make using it a mistake?
Well, that depends on what you want to accomplish. Personality testing is a good way to let people know that other people operate in different ways, based on different habits and preferences. Just because I’d rather read a book and you’d rather go to a party doesn’t mean we aren’t both competent and capable in our jobs. But it does mean that we will probably prefer different kinds of work and work environments, and that we might disagree on what is most important. That could be good to know.
But personality tests will focus our attention on what’s inside a person’s skin as being the most important phenomenon. It’s interesting – in fact, the internal stuff is so interesting that we don’t always look at what goes on between people: conversations, such as making requests, promises, and agreements. Or giving and receiving, of both products and services. And learning – yes, learning is an in-between phenomenon, not an in-the-mind one. Even attitudes, usually thought of as internal, show up in facial expressions (think Grumpy Cat) and tone of voice that are in-between, sent from one person to another.
The in-between deserves a bit more attention. What we see, say, and hear let us know whether there is integrity in our relationships and our business. If I say I’ll call you on Tuesday, and you don’t hear from me all week, my word isn’t going to be worth much to you the next time we talk. If you tell me you’re going to email me a document but I haven’t received it after 6 days, I might want to notice that we didn’t agree on when you would send it (and that I need to make better agreements). And not just integrity is found in the in-between: accountability and credibility are there too.
So fine, use personality tests to help people see the diverse flavors and behaviors in their working world. But communication is not a personality trait. We might consider using a communication diagnostic to learn more about the strengths and weaknesses of productive interaction in our workplaces.
