Why Assessment Choice Matters

With dozens of personality and strengths assessments on the market, the question most asked is which one to use. The more precise question is: which one is right for this purpose, this team, and this moment?  My original publication was done prior to pursuing a Master’s degree in Industrial Organizational Psychology.  This update reflects a validity gap I became aware of, as well as new insights from client work. 

Assessment tools vary considerably in their design, their scientific grounding, and the types of insight they generate. Used well, they provide a structured pathway to understanding the innate skills, preferences, and tendencies of the people we work with. Used without intentionality (or with ill intent), they can oversimplify, pigeon hole, or project a false sense of certainty about human’s complex behavior. 

It’s also worth noting that assessments evaluated here do not identify the presence and competency of specific skills, which is critical for harnessing employee talent.

This guide walks through six assessments used widely in business settings, updated to reflect current research and practitioner experience. It also introduces a framework for selecting the right tool based on your actual organizational need.  Please let me know if you find it helpful!

A Note on Measurement Types

Two terms matter before diving in. Normative assessments compare an individual against a broader population — they measure how much of a trait someone has relative to others. Ipsative assessments rank preferences within the individual — they reveal relative priorities, not absolute levels. Most workplace tools are ipsative; only a few (Hogan, Big Five) are normative. This distinction matters significantly when you’re using data for selection versus development.

1. The Big Five / Five Factor Model

---

The Big Five — measured through instruments such as the NEO-PI-R or IPIP — is the empirical backbone of modern personality science. The five factors (Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism) have been validated across cultures, languages, and occupational contexts, and represent the most replicated findings in the history of personality research.

In full research form (NEO-PI-R), the Big Five is rarely deployed directly in organizational settings because it lacks the accessibility and narrative richness of practitioner-friendly tools. Its primary organizational value is as a calibration standard and selection-grade instrument administered by a qualified practitioner. Non-practitioners utilizing the Big Five can risk increasing unconscious bias if results are not tempered with other objective measures.

BIG FIVE STRENGTHS

Scientific Gold Standard: The most replicated personality framework in psychological research, with robust cross-cultural validity across decades of independent study.

Normative and Continuous: Measures traits on a spectrum and against population norms, enabling nuanced and defensible interpretation, unlike categorical or ipsative tools.

Criterion Validity: Strong links to job performance, leadership effectiveness, and organizational outcomes, making it appropriate for high-stakes selection and succession decisions.

BIG FIVE LIMITATIONS

Limited Practitioner Accessibility: Full instruments (NEO-PI-R) require psychologist-level training to administer and interpret responsibly; not suitable for self-facilitated team sessions.

Engagement Challenges: Clinical language and abstract factor names do not resonate as intuitively as practitioner tools like DiSC or Working Genius which limits direct team application.

Not Designed for Direct Team Use: Best deployed as a diagnostic or selection instrument, not a team workshop tool; requires translation into practitioner language to create organizational value.

2. Hogan Assessments

---

Hogan stands apart from most workplace tools on one critical dimension: it is normative. Results are compared against a global population of working professionals, providing a true measure of how much of a given trait an individual possesses relative to others. This makes Hogan the only widely used business assessment that meets the scientific bar for selection-grade decisions.  Hogan assessments are only administered through a certified professional.

Hogan measures three dimensions: the Hogan Personality Inventory (bright side — how you present when at your best), the Hogan Development Survey (dark side — how you tend to behave under stress or when unguarded), and the Motives, Values, Preferences Inventory (inside — what drives and motivates you). The dark-side derailer assessment is particularly valuable for senior leadership selection and succession planning, surfacing risk behaviors that rarely appear in interviews or standard self-report tools.

Hogan has been administered to over 11 million individuals across 180 countries and 50 languages, and its criterion validity research links results to actual job performance outcomes — a standard most assessments in this guide cannot meet.

HOGAN STRENGTHS

Normative Design: Results are population-referenced, enabling legitimate use in selection, promotion, and succession contexts where ipsative tools fall short.

Derailer Visibility: The dark-side assessment captures risk behaviors that only emerge under stress, which are invisible in most tools and interviews, and disproportionately relevant for senior roles.

Criterion Validity: A strong research base linking assessment results to actual job performance outcomes, a distinguishing and valuable factor.

HOGAN LIMITATIONS

Complexity and Cost: Requires a certified Hogan practitioner to administer and debrief responsibly; not suitable for self-facilitated team sessions.

Potential Negative Framing: The derailer focus can feel threatening if not positioned carefully — facilitator skill and psychological safety are prerequisites.

Access Barrier: Cost and certification requirements limit accessibility for smaller organizations or budget-constrained engagements.

3. DiSC

---

DiSC categorizes behavioral style across four dimensions: Dominance, Influence, Steadiness, and Conscientiousness. Unlike type-based tools, DiSC produces a behavioral profile that describes how a person tends to act under normal conditions versus under pressure, making it especially practical for communication and conflict resolution applications.

DiSC is particularly well-suited for intact teams working on communication norms, manager–employee relationship dynamics, and short-cycle behavior change. It delivers high engagement and immediate applicability without requiring deep psychological literacy. It is less appropriate where skill assessment, deeper psychological insights, or selection-grade validity is required.

DiSC STRENGTHS

Communication Application: Directly actionable for teams; provides language and strategies for adapting to different behavioral styles in real time.

Conflict Utility: Helps teams name and navigate stylistic differences before they escalate into interpersonal conflict.

Ease of Use: Accessible enough for self-facilitated team workshops with minimal external support, making it a cost-effective entry point for team development.

DiSC LIMITATIONS

Surface-Level Depth: The four-style model captures behavioral tendencies but misses deeper motivational and personality dynamics that matter in leadership contexts.

Ipsative Design: Results describe relative priorities within the individual; they do not allow normative comparisons across a population or support selection decisions.

Context Sensitivity: Self-reported behavioral style can shift significantly across contexts, limiting reliability for high-stakes decisions.

4. CliftonStrengths (Gallup)

---

CliftonStrengths identifies an individual’s top themes from a set of 34 talent domains, organized across four categories: Executing, Influencing, Relationship Building, and Strategic Thinking. The premise is that performance gains come faster from developing natural talents than from shoring up weaknesses. This assessment provides validation for an individual’s innate aptitudes, reinforcing confidence and providing valuable language to express personal gifts. It does not highlight developmental needs or team effectiveness gaps.

Gallup has continued to expand CliftonStrengths’ team-level applications since its initial design as an individual tool. Manager-facing dashboards and team grid visualizations now enable facilitators to apply individual results in team planning contexts with less custom work than was previously required. This narrows the gap between individual insight and team application.

CLIFTON’S STRENGTHS

Strengths-Forward Frame: Shifts the conversation from deficit remediation to talent activation, which tends to increase engagement and psychological safety in team settings.

Granularity: 34 themes provide more nuance than four-style models, enabling more individualized coaching conversations and development planning.

Expanding Team Applications: Gallup’s growing team tools make CliftonStrengths increasingly viable as both an individual and team-level instrument.

CLIFTON’S LIMITATIONS

Weakness Blind Spot: The exclusive strengths focus can obscure developmental gaps and potential derailers which is an important limitation in leadership assessment contexts.

Ipsative Design: Rankings reflect relative talent within the individual, not normative strength compared to a population; not appropriate for selection decisions.

Self-Report Bias: Results may be shaped by social desirability or current context rather than stable underlying talent.

5. Myers-Briggs Type Indicator (MBTI)

---

The MBTI remains the most widely used personality assessment globally, categorizing individuals into 16 types based on four dichotomies: Extraversion/Introversion, Sensing/Intuition, Thinking/Feeling, and Judging/Perceiving. Its widespread use is both its greatest asset and, to some degree, its greatest liability.

From a scientific standpoint, the MBTI’s most significant documented weakness is poor test-retest reliability: research has consistently shown that a meaningful proportion of respondents type differently when retested within weeks. This is a distinct and more precise concern than simply “lacking scientific rigor”, it suggests the instrument may not be measuring stable traits. Additionally, the MBTI’s four dichotomies do not map cleanly onto the Five Factor Model, which has the strongest empirical support in personality science. 

For development and communication purposes in low-stakes contexts, MBTI remains a useful conversation starter.  Recent research disproves two of the utilized dichotomies, and it is common for people to feel mislabeled or limited by these labels. It should not be used in selection or promotion decisions.

MBTI STRENGTHS

Accessibility: Widely recognized language makes it easy to introduce in team settings without requiring deep psychological literacy.

Communication Awareness: Helps teams understand different processing and communication preferences, facilitating more productive working relationships.

Engagement: High engagement and self-identification — people tend to feel seen by their type description, which supports initial buy-in.

MBTI LIMITATIONS

Test-Retest Reliability: A significant portion of respondents type differently within weeks, raising fundamental questions about the stability of results.

Categorical Oversimplification: Binary dichotomies (E or I, T or F) do not reflect the continuous spectrum of human behavior captured by stronger instruments.

Weak Criterion Validity: Limited predictive validity for job performance makes MBTI unsuitable for any selection or promotion context.

6. Working Genius

---

Working Genius is a team design tool, not an individual personality assessment. Its primary value is revealed at the collective level — identifying gaps and overlaps in how a team engages with the full cycle of productive work. Individual results are the input; team composition is the output.

Patrick Lencioni’s Working Genius framework occupies a distinct category: it is not a personality assessment in the traditional sense but a model of how individuals contribute to the work process. The six geniuses — Wonder, Invention, Discernment, Galvanizing, Enablement, and Tenacity — map to six phases of productive work, and each person has two natural areas of genius, two areas of competency, and two areas of frustration.

This framing makes Working Genius unusually practical for team design: rather than explaining who people are, it explains how they work, and crucially, where collective gaps may be creating friction, stagnation, or burnout. The ratio is roughly 20% personality, 80% productivity orientation. When used with a full leadership team, the Working Genius map reveals whether the team has sufficient capacity across all six phases, or whether certain stages of work are consistently under-resourced.

WORKING GENIUS STRENGTHS

Team Design: The primary use case — helps leaders identify gaps in a team’s collective capability across all phases of work, not just individual strengths. Most powerful when mapped at the team level.

Burnout Awareness: Directly addresses the source of burnout by naming the work types that drain each person, removing guilt and judgment in the process — particularly effective in post-restructuring or high-load environments.

Simplicity and Speed: The model is accessible enough for teams at all levels without requiring deep facilitation expertise, and yields team-level insights quickly.

WORKING GENIUS LIMITATIONS

Leader-Dependent: Requires self-awareness and openness from the leader to model vulnerability before the team will engage authentically with the framework.

Limited Individual Depth: The framework does not capture the behavioral complexity that other tools address, particularly around interpersonal conflict or leadership derailers.

Ipsative Limitations: As with most tools in this category, results reflect relative preferences within the individual and do not allow normative comparisons across a population.

Choosing the Right Assessment: A Decision Framework

---

The most common mistake in assessment selection is choosing based on familiarity rather than fit. The right tool depends on four factors: the business problem you’re solving, the stakes of the decision, the facilitation resources available, and the organizational context.

Tool	Best Used For	Assessment Facilitation	Scientific Validity
Big Five / NEO-PI-R	Research baseline, selection contexts	Certified professional	Very High — gold standard
Hogan	Leadership selection, derailer risk	Certified professional	High — criterion-validated
DiSC	Communication styles, conflict resolution	Available online, no certification needed	Moderate
CliftonStrengths	Individual reinforcement, coaching	Available online, no certification needed	Moderate — strength-focused only
MBTI	Communication awareness, team-building	Available online, no certification needed	Low — poor test-retest reliability
Working Genius	Team productivity design, role clarity	Certified professional	Moderate — practitioner-validated

A Final Word

---

The best assessment is the one that generates insight your team can actually act on. An unused Hogan report creates less value than a well-facilitated DiSC conversation. The goal for assessment is not to administer the most rigorous tool but to select the right tool for the moment and ensure the results translate into changed behavior, better decisions, and stronger teams.

As organizational complexity grows and the stakes of talent decisions increase, leveraging an I/O Psychologist who understands both the science and the application, and can navigate the space between them becomes a meaningful strategic asset.
