21 Fictional Characters with the ISTJ Personality Type

ISTJ fictional characters

Today we look at 21 fictional ISTJ characters. ISTJs are dependable, dutiful and hard-working. These personality traits come together to make them core members of society.

They are natural problem solvers and good at focusing on the facts and details in front of them. If you’re ever in a crisis, you will want an ISTJ with you!

This personality type takes their responsibilities very seriously and they won’t catch them cancelling plans an hour before you meet up.

Incredibly loyal, ISTJs always have their friends and families backs. This list of fictional ISTJ characters is full of intelligent and rational people who proud of their achievements but don’t brag about too much.

For example, Hermione Granger, who is the top in all of her classes, can be a bit of a know it all when it comes to answering questions but she doesn’t go on about her successes and always blushes when she is complimented.

ISTJs are practical, grounded and focused. From Sheldon Cooper, who is facts focused rather than possibilities focused, to Alex Dunphy, who likes to correct her family’s mistakes, ISTJs take time to analyze what is in front of them and are unmatched when it comes to attention to detail.
