- ISTJ
So Dependable
ISTJs are dutiful, logical and practical. These traits come together to make them core members of society.
When an ISTJ says they will do something, you can rely on them to get it done, and they will not gloss over any of the details either. They take responsibility very seriously. You won’t catch an ISTJ cancelling plans an hour before you’re meant to meet up.
“You are always responsible for how you act, no matter how you feel.”
Robert Tew
When given a task, ISTJs will come up with a step-by-step plan and execute it in a thorough and committed manner. They’re not the jump-in-head-first type. ISTJs will take time to analyse the facts and look at what has been done before. They’re focused individuals and are rarely distracted when working on a project.

Relationships
When it comes to relationships, ISTJs bring security and stability to the table. They’re more likely to offer practical advice to a partner rather than emotional support and tend to be traditional. ISTJs are not the most touchy-feely or openly affectionate people, but they show their love in other ways and having a partner that appreciates this is key for a healthy relationship.
