How a personality type is built

Each type is one choice from each pair. The same four choices show up together often enough that the pattern has a name.

I or E · EnergyIntroverts recharge alone or with a few people. Extraverts recharge around activity and conversation.
S or N · InformationSensors trust what is concrete and present. Intuitives trust patterns, theories, and what could happen next.
T or F · DecisionsThinkers weigh what is logical and consistent. Feelers weigh values and how the choice lands on people.
J or P · StructureJudgers want a plan and a closed loop. Perceivers want room to change their mind.

Questions people ask

What are the 16 personality types?

They are the 16 combinations of introversion or extraversion, sensing or intuition, thinking or feeling, and judging or perceiving. MakeChoice names them Architect, Logician, Commander, Debater, Advocate, Mediator, Protagonist, Campaigner, Logistician, Defender, Executive, Consul, Virtuoso, Adventurer, Entrepreneur, and Entertainer.

What are analysts, diplomats, sentinels, and explorers?

Analysts (NT) decide with logic. Diplomats (NF) decide with values. Sentinels (SJ) keep things steady. Explorers (SP) act in the moment. Each group contains four of the 16 types.

Is this the official Myers-Briggs test?

No. The official MBTI instrument is a paid test. These pages use the familiar four-letter patterns and add careers, relationships, and a free test. A type is a pattern to think with, not a diagnosis or a limit. See research & sources for foundational papers and fair critiques.
