Conclusion
ISTJ stands for “introverted, sensing, thinking, judging” and refers to one of the sixteen personality types of the Myers-Briggs Indicator (MBTI). Those with this common personality type tend to be reserved, quiet, and practical. They are self-sufficient and work hard to meet their obligations.
ISTJs are usually blunt and to the point rather than dreamy with their goals and ambitions. They often seek solutions to problems without delaying themselves and are pretty hesitant to take risks. In other words, ISTJs are strong in their beliefs, which can make them stubborn.
Also known as the Logistician or Investigator, INTJs are planners. They love preparing for things in an orderly fashion and pay a lot of attention to detail. They’re typically comfortable in familiar surroundings and often rely on conventional means and proven methods.
