Best Personality Tests for Team Building
July 21, 2026
Team friction comes at a cost.
Projects stall. Progress gets derailed. Team meetings become a waste of time.
Worse, friction within a team can turn into resentment, contempt, or the silent checking out of a previously valuable member.
And that friction can keep products from being shipped, can delay launches, or cut into profits.
Since teams naturally include a variety of people, friction issues often get filed under “personality differences.” The next natural step is to go looking for a personality test for team building, hoping the right one will help you either right the wrongs or at least hire better the next time.
If you’re comparing team building personality assessments, it’s important to understand what the tools do, the science behind them, and what you’ll do with that information after the last assessment result gets collected.
Personality tests for team building: what do they do, exactly?
A team building personality test sounds fun, but for a leader, manager, HR consultant, or entrepreneur, it could be a critical tool for understanding a team and cutting friction off before the stakes hit the P&L sheet.
So the real question is:
Do they work?
Personality assessment tools are well-supported as tools for self-awareness and can benefit shared language, team understanding, and communication.
However, they are weakly supported as tools for predicting the performance of an individual or helping you make your next team hire.
- Do: use them to better understand the personal and relational dynamics in a team.
- Don’t: expect them to provide the answer to, “Should I hire/ fire this person?”
Different tools can be used for different goals, so let’s look at some of the top-used team building assessment tools and where they shine. We’ll compare more in-depthly later as we go on, but the quick comparison is:
- Communication workshops: DisC
- Strengths and engagement development: CliftonStrengths
- Role fit: The Predictive Index
- Leadership selection: Hogan
- Shared vocabulary for a team: MBTI or 16Personalities
- Understanding relational dynamics and resolving friction: SHEER Personality
Does science support personality assessments for team performance?
Your team is made up of humans. And humans are wired for connection and built for relationships.
They’re also individuals made up of unique personalities, patterns, and ways of operating and showing up in the world.
Which means that sometimes, one team member’s patterns and modus operandi can show up in opposition to someone else’s.
Some of these personality traits can have a direct impact on team performance.
When researchers performed a meta-analysis on personality traits and team performance, they found that two traits in particular were linked to better performance:
- Agreeableness: your relationship to harmony
- Conscientiousness: your relationship to structure
Despite these findings, there’s no “perfect” personality profile for your team members to possess.
Researchers using an Agent Based Model (ABM) of the Big Five personality traits found that the ideal personality trait for team performance can change based on the type of task at hand.
For tasks with noise—think open-ended tasks such as entrepreneurship or managing organizational behavior—a team leaning more harmonious/ agreeable and willing to prioritize the emotional safety and relational ease in a group, produced the best results.
However, for tasks with no noise—tasks with definitive solutions, such as accounting—a team that leans more challenging/ lower agreeableness and is more willing to move toward tension or push back on assumptions performed better.
If science supports certain personality traits as more likely to predict better team performance, but also recognizes that better performance is dependent on the task at hand, that makes it pretty difficult for a leader to assemble a team based on personality assessment results or traits alone.
Personality assessments for reducing team friction
One way to utilize a personality assessment for team building is to consider a tool that’s built to reduce team friction, like SHEER Personality.
SHEER Personality is based on Big Five science but designed as a relational intelligence tool.
The SHEER Personality assessment measures where your team members fall individually across five personality dimensions. Instead of a set “type,” these dimensions show where someone sits along a spectrum.
The result is a constellation: a shape that indicates someone’s personality traits along these spectrums.
Like many individual assessment tools, SHEER Personality provides insights that allow you to see yourself clearly and foster better self-awareness. See how it works.
Where SHEER excels as a personality assessment for team building and improving relational intelligence (RQ) is its ability to:
- Highlight where you can easily be misunderstood by others based on your unique constellation (and how to work around these areas).
- Overlay team member constellations to easily see the distance and gaps between dimensions and identify possible areas of friction.
Here’s how that works in real-life team-based scenarios.
Individual insights
An individual takes the SHEER Personality assessment and realizes that they lay on the Reflective end of the Expression dimension. That means this person often needs time to think before responding, processes information internally, and their thoughts become clearer after they’ve had time to sort through them on their own.
This insight feels accurate to the individual; they do prefer time and space to process information.
But their assessment results also reveal something they haven’t considered before:
That same Reflective quality can often be misread by others, who assume they are disengaged or uninterested in the conversation at hand. They may appear “checked out” in meetings as they sit back and listen without contributing, or even mislabeled as “rude” or “problematic” by teammates who want to talk through a problem in real time.
Understanding where they are on the Expression dimension, and how that could be misinterpreted by someone who leans more Expressive than Reflective, provides valuable insights that can ease friction in team situations.
All it takes is one small moment in a meeting or other team environment to say: “I just need a minute to process this and make a decision. I’m still here with you.”
Team overlays
As a team leader, you may be able to see the potential for pitfalls or friction before your team does by exploring two or more people’s personality constellations.
Because friction between team members typically comes when there is a large gap along one dimension.
Let’s say you have two team members positioned on opposite ends of the Structure dimension.
- One team member is highly Structured. They thrive with systems, due dates, clear expectations, and anticipated next steps.
- Another team member is highly Adaptive. They thrive when they can pursue a goal creatively, flexibly, and with the freedom to pivot and adapt in the moment.
In a team environment, it’s easy to see that trying to get both of these team members operating within the same system, working on the same goal, in the same way, could create tensions, friction, and misunderstandings.
Noticing these gaps along dimension lines allows you, as the team leader, to call out the tension before it leads to disrupted trust, missed deadlines, or contempt between the team members.
And it allows for a conversation about how to structure the environment and systems in a way that works best for both, not just one or the other.
Personality tests for teams that reveal a type or a strength can have their place in helping foster better self-awareness or self-understanding for an individual team member.
But an assessment that reveals where two people sit along a personality dimension can go even further to improve the relationships between them.
What’s the best personality test for team building?
There is no single “best” tool for assessing your team. However, there are certain assessment tools that help you reach your goal as a team leader. Here’s how the top assessment tools break down for team building purposes:
Everything DiSC
Everything DiSC is a simple model that measures four basic behavioral styles. Includes access to colleague’s results for better understanding of others. It's fast, and the results are simple enough to use immediately. Highly validated, though mostly through its publisher. What DiSC won't do is predict performance or tell you who should work with whom. Its best use is as a practical communication workshop that gives a team quick language for how they each operate.
CliftonStrengths
CliftonStrengths identifies a person's top talents from 34 themes and gives them affirming language for what they're naturally good at. The team grid shows how strengths spread across a group, which helps with development and role design. Most of its validation comes from Gallup rather than independent researchers, and it won't diagnose friction or predict who to hire. Its best use is strengths-based development and engagement with teams that respond to building on what's working.
The Predictive Index
The Predictive Index measures behavioral drives, with a separate short cognitive assessment, aimed at hiring and role fit. Most of its validation is in-house; across its significant studies the average correlation to job performance is about 0.30. It isn't a communication or development tool for a team already in place, and it's enterprise-priced and sales-gated. Its best use is hiring, role fit, and workforce planning where speed and consistency across many candidates matter.
Hogan
Hogan assessments measure how someone performs at their best, how they derail under pressure, and what they value. It has the strongest independent research footing of the group, which is why it's the standard for high-stakes leadership decisions. It needs a certified interpreter, it's privately priced, and it's more depth than most team building calls for. Its best use is leadership selection, derailment risk, and executive development.
MBTI / 16Personalities
MBTI sorts people across four preference pairs into one of sixteen types, giving a group a memorable shared vocabulary fast. That recognition makes it a comfortable icebreaker for a team offsite. Retake it a few weeks apart and many people land on a different type, and it doesn't reliably predict job performance. Its best use is a shared language for a workshop, held lightly, but may not be idea for a hiring or team-composition decision.
SHEER Personality
SHEER Personality maps relational patterns across five spectrums, built to show why specific people keep creating friction. Two of its spectrums, Structure and Harmony, are the exact traits the team-performance research points to, and its overlay puts two people's patterns side by side so the gap between them is visible and named. It isn't a hiring screen, it doesn't measure attachment. Based on Big Five research with its own validation still in progress. Its best use is understanding and working through the recurring friction between specific people.
