ISTP — The Mechanic
Hands-on problem-solver who moves fast through obstacles
5% of population
ISTP (Introverted, Sensing, Thinking, Perceiving) is one of the sixteen MBTI personality types, representing about 5% of the population. ISTPs are practical troubleshooters who excel at diagnosing what is broken and fixing it efficiently through hands-on investigation. They prefer working with tangible systems and tools over abstract theory, and they think best whilst doing rather than planning. Their ability to stay calm under pressure and adapt quickly makes them invaluable in technical fields. Common careers include mechanical engineer, electrician, software developer, paramedic, and forensic analyst. Notable ISTPs include Tiger Woods, Clint Eastwood, and Serena Williams.
