How to Introduce Personality Testing to a Skeptical Team

Gallup's 2026 State of the Global Workplace report puts global employee engagement at 20 percent, the lowest reading since 2020 and the second straight year of decline. The steepest drop sits with managers themselves, whose engagement has fallen nine points since 2022, wiping out the "engagement premium" they once held over the people they lead. Put simply, the people responsible for rallying teams around new ideas are running on empty, and the teams they lead know it.

That's the backdrop against which any manager proposing personality testing as a way to build productive and engaged teams has to operate. A team already stretched thin, already wary of the next initiative layered onto an overflowing plate, isn't going to greet a personality assessment with open arms just because the science behind it is sound. Skepticism here is a rational response to a workplace that has asked people to absorb a lot of change in recent years, often with very little payoff to show for it.

So the goal isn't to convince a skeptical team that personality testing is exciting, it's to earn the right to use it at all.

Acknowledge the Skepticism is Often Valid

Plenty of people have a personality test story that soured them on the whole category. Most often, it’s because they once ‘failed’ an employer’s personality assessment and it cost them a dream job. Or maybe a manager read someone's type off a printout too literally and treated it as a fixed verdict on how far that employee could go. Organizational psychologists — including the experts here at Truity — warn against relying on personality assessments to predict  job success, because there is little to no correlation between the two. 

A manager who opens with a hard sell on a test’s reliability and validity won’t win over an employee who has had a poor personal experience in the past. For these employees, it’s more useful to name the concern directly. Say plainly that this isn't about ranking anyone, deciding who gets promoted, or replacing human judgment about someone’s performance or potential with a test result. Rather, it’s about evaluating how employees behave, communicate and solve problems, and building a better understanding among people already on the same team. Most resistance softens considerably once people believe the exercise won't be used against them.

Choose the Right Framework for the Team

Managers often reach for whichever framework is most familiar: Myers-Briggs because everyone's heard of it, or DISC because a past employer used it, without asking whether it actually fits what the team is trying to achieve. That mismatch is where a skeptical team loses confidence. Someone sitting through an Enneagram session aimed at deep self-reflection or long-term career growth, when what they needed was a practical fix for miscommunication in meetings, walks away with a fair complaint that the exercise wasted their time.

The reality is that different personality frameworks serve very distinct goals:

• The Big Five assesses an individual on five spectrums (Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism) to predict real-world life outcomes, such as career performance, personal development and stress management.
• TypeFinder®, based on Myers-Briggs, provides an understanding of cognitive style and decision-making. It categorizes people into 16 psychological types based on how they take in information and make decisions, and is primarily used for personal growth, career alignment and team-building.
• The Enneagram maps an individual’s underlying motivations and blind spots. Instead of measuring behavior, it focuses on the core fears, desires and emotional drivers behind actions, and is used heavily for deep self-awareness  or strengthening how a team supports each other's resilience and growth. 

• DISC describes specific, observable behavior, such as how someone prefers to receive feedback and how they handle conflict, rather than deeper personal values and  motivations which some employees may feel uncomfortable sharing with the team.  It helps people adapt their communication styles, resolve conflicts, and collaborate better in office environments. 

If you’re not sure which assessment suits your needs, Truity’s project planner exists for exactly this reason, and it’s worth a manager's time before committing to a particular framework.  What matters is that you can explain the reasoning behind the assessment you’ve chosen. A manager who explains, plainly, why a particular tool fits what the team is trying to achieve shows a skeptical team that real thought went into the decision, and that tends to earn buy-in.

Lead With a Finding The Team Already Recognizes 

For cynical teams, you may find the skepticism starts to crack the moment a framework tells a team something they already know to be true about themselves, before anyone has even taken the test. Confirmation bias is a cognitive shortcut where your brain naturally seeks, interprets and supports information that aligns with your current worldview, and there’s a related pattern called the illusory truth effect, which says that when something feels familiar, the brain reads that ease of recognition as a signal of accuracy, even though familiarity and truth aren't actually the same thing.

Here's an example. Say the team has grumbled more than once that Tom agrees with a decision in the room, then raises legitimate, important objections a week later, once the plan is already in motion. It's a pattern everyone's clocked, and it costs the team a lot of time. 

A manager can build buy-in by naming the pattern out loud, then introducing the idea that a personality type like ISFJ in the Myers-Briggs system, or a Support type in DISC, often keeps quiet to avoid conflict in the room and needs time alone with a decision before trusting their own doubts. Tom is not being difficult here, and it is not his fault that he needs time to mentally organize details. What personality science brings to the table, besides understanding, is a practical way through this challenge. It can help the team consider how the meeting itself could be restructured in a way that supports the team’s goals while giving individual team members like Tom the freedom to work in a way that suits them. 

Go First

Before asking anyone else to take a personality test, a manager can take one themselves. Truity's free assessments take about ten minutes, and the result gives a manager something concrete to bring into the next team meeting. 

Say the manager tests as an ESTJ in the 16-type system. They learn that their tendency to make fast decisions is driven by their need to take immediate action rather than getting bogged down in endless deliberation, but it can be read as dismissive to people who want more discussion before rushing to a decision. Share that specific finding with the team, including the warts-and-all parts that sting a little. Then share how you’re going to adapt to lead more effectively, such as committing to sleeping on a decision before finalizing it or creating a mandatory "review and refine" stage in your project plans to check for overlooked details.

Honesty like this does more to open the door than any explanation of what personality testing is for. Skepticism is a lot harder to hold onto once the boss blinks first.

Keep it Optional

Participation in personality testing should always be a voluntary team exercise, and someone who prefers not to take the assessment should still be welcome in the discussion that follows. Much of the value comes from the conversation about working styles rather than the individual scores themselves anyway, and you may find that someone who sat out the test still gets plenty out of a well-run team building workshop, where the discussion does most of the heavy lifting. 

Revisiting the framework periodically helps a team get even more value from it. Teams that check in on their own and other’s working styles as projects and team makeup shift tend to keep finding new, practical uses for the same insights, and that ongoing use is often what brings the holdouts round. Someone who skipped the test the first time, having watched the framework actually change how meetings run or how feedback gets delivered, will often ask to take it once they can see it's solving real problems rather than sitting in a drawer somewhere. 

Winning Over a Skeptical Team, for Good

Given how thin workplace engagement has stretched and how much trust between managers and their teams has eroded over the past few years, a tool that builds genuine mutual understanding earns its place, provided it's introduced with purpose and humility. 

Get this right, and the payoff is concrete. Meetings run better once people understand why colleagues process decisions differently. Feedback lands the way it's meant to, instead of getting lost between different working styles. A new team member settles in faster once the team already has language for how everyone works, rather than having to pick it up by trial and error. None of that requires convincing anyone that personality testing is ‘scientific’ or ‘exciting’ or a way to ‘fix’ a broken team. It just requires a manager willing to address the doubts directly, and structure the process to feel safe and rewarding.
