Famous ISTJs deal with popularity by being dismissive because they don’t want to be the center of attention. They’re introverts who’d rather live a private and structured lifestyle.

What other personality type is the best match for ISTJ?

Three other personality types are the best match for an ISTJ relationship. First, the ESTJ personality type pairs well with ISTJ because the two are similar. ESTJs and ISTJs are both reliable, practical personalities who value logical thinking and greatly respect one another’s opinions. Second, the ISFP personality would be a good match for an Inspector because they can communicate well. Their opposing worldviews complement each other and allow the other to view issues from different perspectives, fostering a healthy balance between them. Third, ISTJs are very compatible with ESFPs as they share the Sensing (S) function and are both highly realistic personality types. Furthermore, their opposing Extroversion-Introversion can help Inspectors act less stiffly and improve ESFPs’ work ethic.
