All 16 types

MBTI type

ISFJThe Guardian

Looks after people quietly and thoroughly.

You notice what others need and take care of it, often before being asked. Loyal, practical and modest, you value harmony and continuity and carry a great deal without making a show of it.

The four letters

I

Introverted

S

Sensing

Trusts facts, details and what experience has shown.

F

Decides by values and the effect on people first.

J

How this preference often shows

  • Attentive, practical care
  • Reliability people can lean on
  • Remembering what matters to each person

Worth watching

  • Ask for help before you are exhausted
  • Let a change happen without first defending the old way

A type is shorthand for the preferences you report, not a fixed kind of person. Most people sit close to the middle on at least one letter, and that letter can come out differently on another day. Read a type page as a mirror: keep what fits, leave what does not.

One letter away

These four types differ from this one by a single letter. That is a distance in letters, not a measured similarity; if one of your letters is only a slight lean, its neighbour may describe you just as well.
