He adds that these are also organized people, both at work and at home, who enjoy getting tasks done (preferably alone without distractions). But that trait comes with a downside: “They concentrate on logic and facts so much while making decisions that often they don’t consider how other people feel or are impacted by what they do,” Hackston notes. But according to therapist De-Andrea Blaylock-Solar, LCSW, CST, while they may not be the most sensitive, they are dedicated, responsible, and honest. “They are very careful to keep commitments, so they’ll only agree to things they can fully commit to,” she tells mbg, adding that some areas for growth include being stubborn and always following specific rules, not making space for learning or creating new ways of doing things, and being self-critical. While generally good partners, it may just take a little extra time to get these people to open up. As Hackston explains, “People with ISTJ preferences are private and not always easy to get to know, but once they are in a relationship, they are very committed.” He adds that they tend to take on a traditionally gendered role and assume or expect that their partner will do likewise. “They appreciate dependability and reliability and will try to make sure their significant other feels heard. On the other hand, they will probably have a hard time dealing with drama,” he explains. In terms of MBTI compatibility, Hackston notes that the ISTJ type meshes well with others who have the same sensing-thinking preferences (aka practical, factual, and direct)—so ISTP, ESTJ, ESTP, or another ISTJ. And along with making great leaders, they’re also great team members as well, he says, even though they tend to be quiet and process things internally. Thinking about structure and organization, Blaylock-Solar notes that careers with direct policies and clear boundaries will suit ISTJs, with Hackston adding “direct communication, clarity on everyone’s role, and practical instructions are important for them when dealing with coworkers.” Being the most common MBTI type, you’ll find ISTJs in a number of fields, with the most important factor being that their job involves organization and factual information, according to Hackston.
