ISTPs are the people you want around when something breaks, literally or figuratively. Their strengths are practical intelligence and composure; their weaknesses usually involve emotional expression, planning and patience with routine. For the full profile, see the ISTP guide.

In Everyday Situations
| Situation | Strength | Weakness |
|---|---|---|
| Car breaks down | Diagnoses and fixes it | Ignores the service schedule until then |
| Friend in distress | Stays calm and practical | Struggles to offer emotional comfort |
| Team project | Finds the efficient solution | Skips the documentation |
| Weekend plans | Up for any adventure | Will not commit until the last minute |
Under Stress
ISTPs under heavy stress may become unusually emotional or sensitive to what others think, as their least-developed function, Extraverted Feeling, comes forward. They can also become reckless as a way to escape.
Growth Tips For ISTPs
- Practise naming feelings, even in a single word.
- Schedule boring tasks in short bursts with a reward afterwards.
- Think one step further ahead before taking big risks.
- Share plans with people who depend on you.
