Understanding the assessments

A short primer on each test — its origin, what it measures, how to use the result, and how to communicate across types.

MBTI

how you get energy, take in information, decide, and organise life

Where it comes from

Created by Katharine Cook Briggs and Isabel Briggs Myers in the 1940s, building on Carl Jung's theory of psychological types. It is hugely popular and useful for self-reflection and communication, though its scientific reliability is debated — use it as a conversation starter, not a fixed label.

What it measures & why

Maps 4 preference pairs — E/I (where you get energy), S/N (how you take in information), T/F (how you decide), J/P (how you organise life).

How to use it

  • Greater self-awareness
  • Smoother team communication
  • Understanding each person's work style
  • Reducing misread intentions

How to read your result

Your result is a 4-letter type; each letter is a PREFERENCE (a lean), not a box. People use both sides — it's about which one feels more natural and comfortable.
