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.

It would be nice if employers understood this. I've read nothing but negative feedback from forum posts about people who've been rejected for consideration due to their personality test results.

Very true. We should just have a bit of everything that people have to offer say you have just Thinkers, they might be good logically but then they might not consider when others need help or support, but too many Feelers and then the job might be more focused on feelings rather than logic. Get it right and then you will have a good team.

I think that the personality types are a powerful tool to understand existing dynamics in an office but shouldn't be used to decide on new hires. The worst manager of my life put me through a personality test, an aptitude test, a physical, wanted me to make example design work for her, and made me take a drug test, for my application to an underpaid design position where she micromanaged the hell out of me. I could have predicted that. I only lasted 9 months at that agency before finding a job somewhere that paid twice as much and gave a lot more freedom. I've never been asked to take any kind of test there. I shared my test, voluntarily, with my current manager, and she shared her results with me, and it's helpful for me to know how to interact with her better. But it had nothing to do with my employment.

I think many employers are missing the point that this is terribly unethical. Personality type is a personal info that is not necessary to perform job duties. I think it's ok to want to understand personality types of your team but that can only come as a result of building trust with the team and good communication, managerial skills and environment of trust. And taking such tests can be only voluntarily. When anyone wants people to do this test straight away it's an attempt of cutting corners and wanting to know too much about candidates. It's not ok to spy on employees in their free time even though one could make a theoretical argument that how they spend their free time(stuff like getting enough sleep) will affect their productivity at work. Why personality should be any different? Besides there is a name for picking candidates based on traits like that - discrimination. If someone would ask me to fill such a test I wouldn't want to work for them. If some manager on my project of today would ask me to do that test I'd refuse and would probably go digging some laws on if it's appropriate to collect this kind of personal data in a country where I live in legal terms.

Exploring the personality types of a team can be very interesting and motivating. To know the personality type of an individual team member can therefore be very valuable. So, this is the reversed modus operandi of using personality typing assessments for hiring people. Do not hire people based on their personality type, but study the personality types of existing team members for the sake of understanding team dynamics.
