Psychometrics (Inspire)
Not a single instrument but a reference guide for choosing between psychometric tools, matched to what you actually need to know and who you're asking it of.
Three boxes walk you from shortlisting by context, through comparing on reliability and fit, to selecting for the purpose and the population.
Reach for this when…
- Someone asks for a personality test without saying what decision it's meant to inform.
- You're choosing between two assessment providers and can't tell what actually differs.
- A previous assessment gave contradictory results and nobody can say why.
How to run it
- Use it as a reference to shortlist instruments that suit the context.
- Compare on reliability, validity, normative data, and ease of administration.
- Select the instrument that fits both the purpose and the population being assessed.
A worked example
Situation. Noa Peretz, head of people at a fast-growing wine export business in Tel Aviv, Israel, had three managers using three different personality tools with no way to compare results across teams.
Applied. Using the reference guide, she checked each tool's normative data against her own workforce and dropped the one built on a US executive sample rather than her mostly frontline population.
Result. One validated instrument for one clear purpose, hiring for supervisor roles, replaced the mixed toolkit. Managers stopped arguing about which report to trust.
The catch
The guide tells you what to compare, not which specific tool is right for you, and picking well still needs someone who understands psychometrics, not just a checklist. A validated instrument used by an untrained interpreter is still a bad assessment.
If you cannot say what decision the result will change, you do not need the instrument yet.
