Can I Use This Personality Test to Filter Potential Employees?

Leeza's avatar

Here’s the short answer: you can, but you really shouldn’t.

As long as personality assessments have existed, employers have asked the question, “Is it all right to use these results to weed out bad or ineffectual workers?”

And the answer is no.

No, no, no, no, no.

No.

While we can’t truly enforce whether you use our test to screen job applicants, we can tell you two reasons why this would be a bad idea.

Take the Test

Reason #1: Someone’s Personality Type Is Not a Reliable Indicator of Their Professional Success within a Specific Field

We become what our work needs us to be. For example, if a person has a high score for Introversion, but their work needs them to be talkative and socially driven in order to succeed, then they will become that person for short bursts throughout the day.

Is it their preference to be that? No.

But are they capable of it? Yes.

This can be said of all the personality trait pairs – Introverted vs. Extraverted, Intuitive vs. Observant, Thinking vs. Feeling, Judging vs. Prospecting, and Assertive vs. Turbulent.

That’s why it’s a bad idea to filter out employees based on their personality assessment results. You’re filtering them out based on how they perceive themselves and not what they’re capable of.

Reason #2: Too Many [Insert Trait Here] Personalities Can Make for an Unbalanced Team

Suppose you disregard the above, and you still want a team composed mostly of, say, Intuitive personality types. And why wouldn’t you? Intuitive types, when left to their own devices, can be extremely visionary people. They often work outside the established lines and can push your company to new, never-before-seen heights.

But who is dealing with the logistics of things? Who is taking the practical steps, the steps that have already been proven to work? Who is making things much easier by suggesting, “Hey, this method already works. Why don’t we just repeat it?”

The same could be said if the situation were reversed. Too many Observant types may keep your team from innovating in a quickly changing landscape.

See, one of the beautiful things about having many different personality types on your team is that you’re able to see from several different perspectives, take a bevy of insights, and then decide on the right path.

I've always disliked the idea of hiring people based on their personality types. After all, it's very difficult to truly make out a person's entire mindset and thoughts when all you have for evidence is 100 questions. I believe the best thing to do when trying to find an employee is to just get to know them. :)

You could go the other way and rather than wanting all intuitive (as per the example) types in the team, seek more balance, meaning you might turn down intuitive types if you already have plenty of them on board. Of course, the traits aren't black and white - I'm actually 34% observant and would maybe switch that up if surrounded by people all being very intuitive. I would personally avoid recruitment decisions based on type. Instead I'd be looking at the detailed profile here to understand how I might bring out the best in someone.

However, the personality type can still be an extremely helpful bit of information, because if you are capable of taking that into account when managing your employees, you could do a bit of juggling with the composition of your teams, and once you know what makes your employees tick (by observing how they are tackling their tasks) you can start tweaking your processes to better fit the personality types of your employees so that you are getting better overall performance. What would be a better kind of motivation than people who feel understood and appreciated for what they are?

This is so true! Thank you! One of the best things about working in a business is the variety of people with all kinds of amazing personalities, using their specific talents to create a good TEAM.

Reason #3: People can lie. My INFJ mum asked her 16 new employees (she is the manager of them) do the 16personalities test a week after they got employed. Six of them (all girls by the way) came out as ‘Assertive Consuls’ (‘ESFJ-A’). Most of those ‘Consuls’ probably lied because they want to look like they have a good personality type. Why most of those six people are not Consuls? Because they did that test over a year ago and four of those six people still do not seem/behave like Consuls at all, in fact three of those four who pretended to be Consuls ended up the being the most trouble/bad workers for my mum. So, I suggest you try to type people by using your own experience/opinion, not what they say they are.

So your mother should be on the lookout for more red flags that are indicating real trouble. If that really turns out to be a lie, there could be more going on behind the scenes than may be visible at first glance, and your mother being an INFJ could easily be taken advantage of by narcissists or people with other personality disorders. Since they are obviously performing poorly, they should be canned, anyway, because what good do they do if they may be sociable but are causing everything else to bog down?

This actually does make a lot of sense!
