Anyone searching for "personality test" online quickly lands on four names: CliftonStrengths® (Gallup), MBTI® (Myers-Briggs), DISC and Big Five (OCEAN). All four promise self-insight – but they measure different things, rest on very different scientific foundations, and are suited to very different purposes.
This cornerstone article compares the four tools honestly: what do they measure? How robust are they? What are they worth – and where do they fall short? By the end you will know which instrument (or combination) fits your question.
The four tests in short
CliftonStrengths® (Gallup)
Developed by Donald Clifton in the 1990s, today distributed by Gallup. Measures 34 talent themes across four domains (Executing, Influencing, Relationship Building, Strategic Thinking). Result: an individual ranking of your top talents. Core assumption: building on strengths creates more impact than fixing weaknesses.
MBTI® (Myers-Briggs Type Indicator)
Developed in the 1940s by Katharine Cook Briggs and Isabel Briggs Myers based on Jung's typology. Assigns people to one of 16 types (e.g. INTJ, ENFP) via four binary dimensions (E/I, S/N, T/F, J/P).
DISC (also DiSC)
Goes back to William Moulton Marston (1928), commercially distributed by Wiley (Everything DiSC), TTI Success Insights and others. Measures four behavioural styles: Dominance, Influence, Steadiness, Conscientiousness. Focus: observable behaviour in the (work) context.
Big Five / OCEAN
The most academically respected model. Result of decades of research (Costa & McCrae, Goldberg and others) and measures five continuous dimensions: Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism. Used in research, clinical psychology and – with expert screening – in selection contexts (e.g. NEO-PI-R, IPIP scales).
The big comparison
| Criterion | CliftonStrengths® | MBTI® | DISC | Big Five (OCEAN) |
|---|---|---|---|---|
| What is measured? | 34 talent themes (ranking) | 16 types (categorical) | 4 behavioural styles | 5 personality dimensions (continuous) |
| Theoretical basis | Positive psychology, talent research | Jung's typology (adapted) | Marston (1928), behavioural psychology | Lexical approach, empirical |
| Scientific recognition | Medium – Gallup-internal validation, growing peer review | Low – largely criticised in academic psychology | Low–medium – varies strongly by vendor | High – scientific gold standard |
| Retest reliability | Good (top-5 relatively stable) | Contested – up to ~50 % get a different type after weeks | Vendor-dependent | Very good |
| Output format | Personal talent ranking | Type code (e.g. INFJ) | Style profile (e.g. "high D, medium C") | Individual profile on 5 scales |
| Primary purpose | Strengths development, coaching, teamwork | Self-reflection, team dialogue | Communication, sales, team dynamics | Research, differentiated personnel diagnostics |
| Suitability for hiring | Limited (talent ≠ competence) | Not recommended | Not recommended | Most suitable (with expert screening) |
| Language / availability | 20+ languages incl. EN | Many languages | Many vendors, many languages | Numerous free & commercial scales |
| Price (retail, indicative) | Top-5 from ~CHF 22, all 34 from ~CHF 62 | ~CHF 50–90 (official test) | vendor-dependent CHF 40–150 | from free (IPIP) to several hundred CHF (NEO-PI-R) |
| Coaching impact (practice) | High – concrete language for strengths | Medium – good door-opener, limited depth | Medium – good for communication | High, but explanation-heavy |
Scientific classification – without the marketing filter
Big Five: the gold standard
In academic personality psychology the Five-Factor Model is considered the best-validated model. Factor structure, reliability and predictive validity (e.g. for job performance and satisfaction) are well documented. If you want maximum scientific grounding, Big Five is the answer.
MBTI: popular, but contested
MBTI is popular, yet academic criticism is clear: binary categories instead of continua, high retest instability and weak predictive validity for job performance. As a structured self-reflection trigger it can still open doors – for hiring decisions it is unsuitable.
DISC: pragmatic, but vendor-dependent
DISC is deliberately behaviour-oriented and easy to convey – especially in sales, customer communication and team workshops. Scientific quality strongly depends on the vendor. As personality diagnostics in the narrow sense DISC is too narrow.
CliftonStrengths: the pragmatic coaching standard
CliftonStrengths® was not built as an academic personality model but as an applied talent tool. Top-5 reliability is good, the language concrete and coaching-friendly. Limitation: it measures talent potential, not values, maturity or motivation.
Which test for what? A decision guide
• Career and purpose decisions: CliftonStrengths® (talents) plus a values-based method such as Profilingvalues (values/motivation).
• Leadership development: CliftonStrengths® for self-leadership, combined with 360° feedback and Big Five for a deeper profile if needed.
• Team workshops / communication: DISC or CliftonStrengths® – DISC for communication and sales, CliftonStrengths® for roles and task allocation.
• Hiring: No single personality test as a knock-out criterion. Big Five combined with technical assessment and structured interviews.
• Self-reflection / entry level: MBTI or DISC as door-openers – but never treat them as a diagnosis.
Common misunderstandings
• "The test tells me who I am." No test measures identity. It measures patterns.
• "Talent = job." CliftonStrengths® shows potential, not job lists.
• "MBTI is scientifically validated." In academic psychology largely not.
• "One test is enough." Robust coaching usually benefits from two perspectives: talents and values.
Our recommendation from 400+ coachings
In practice we most often combine CliftonStrengths® 34 (talents) with Profilingvalues (values, motivation, role fit). This combination reliably provides two things a single test rarely delivers: clear language for one's strengths and an honest assessment of values and motivation.
MBTI or DISC we use selectively when a team already works with them – never as the sole basis for career or hiring decisions. Big Five we recommend when a differentiated, scientifically grounded second opinion is required (e.g. reorientation after burnout).
How to proceed
Wondering which test really helps in your specific situation – without getting lost in marketing claims? In an informal first call we frame your question and recommend the right path.

Bottom line
There is no single best personality test – only the one that fits your question. Scientifically Big Five leads. For concrete strengths and career work, CliftonStrengths® delivers the most actionable language. DISC helps in communication and sales. MBTI is fine for self-reflection – not for decisions with consequences.

Frequently Asked Questions
Which personality test is scientifically the most robust?+
In academic psychology the Big Five (OCEAN) model is considered the gold standard. It has the best factor structure, high retest reliability and the strongest predictive validity for behaviour and job performance. MBTI is largely criticised in research, DISC quality depends heavily on the vendor, and CliftonStrengths® is a solid applied talent tool but not a classic personality test.
Is CliftonStrengths better than MBTI?+
For career and strengths work, usually yes. CliftonStrengths® gives you an individual ranking of 34 talents and a very concrete language for shaping roles and tasks. MBTI puts you into one of 16 types and is more useful as an entry point for self-reflection. MBTI should not be used as a knock-out criterion in hiring.
Can I use CliftonStrengths, DISC or MBTI for hiring?+
No personality test should decide alone about hiring or rejection. Big Five is scientifically most suitable, MBTI and DISC are not. CliftonStrengths® can indicate talent fit but does not replace a technical assessment or structured interviews.
How do the four tests compare in price?+
CliftonStrengths® Top-5 starts around CHF 22, all 34 themes from about CHF 62. The official MBTI costs roughly CHF 50–90 depending on the vendor. DISC reports range from CHF 40 to 150. Big Five is the most widely available: from free IPIP scales to several hundred CHF for validated instruments like the NEO-PI-R.
What combination does PurposeCoach® recommend in practice?+
In over 400 coachings, the combination of CliftonStrengths® 34 (talents) plus Profilingvalues (values and motivation) has proven most powerful. It links clear language for your strengths with a robust view on values and role fit – two dimensions that a single personality test rarely covers at once.
