ST Leaders:
Doing it Right the First Time

Key contributions of ST leaders were found to include many activities related to the execution of work; not surprising given their common ‘bottom line’ approach. Their top strengths were listed as solving problems and analyzing issues (81% of those surveyed) and taking initiative (68%). As a result, it is likely that in leadership positions, ST leaders will be naturally good at:

  • Taking action and staying focused on objectives
  • Analyzing information and solving problems
  • Developing efficient procedures and policies
  • Applying their depth of knowledge and experience to challenges

ISTJs and Stress

Stress triggers for people who prefer ISTJ can be situations that challenge their natural preference for structure and logic, and by the factors highlighted in the MBTI® Stress Head above. During initial stress, they may seem a bit rigid and not open to new ideas. In extreme circumstances they may become accusatory and pessimistic, tending to withdraw and shut down emotionally.

ISTJs and Conflict

For people who prefer ISTJ, “conflict is something that needs to be dealt with so they can get on with life” (Introduction to Type® and Conflict, p. 24). Their direct approach to conflict, however, can sometimes feel a bit too direct when you’re on the other end of it.

The TJ conflict style from people who prefer ISTJ works when they are addressing the conflict head-on and then moving ahead. However, if they keep on that track for too long, it can come across as overly critical. People who don’t share their direct approach might not see it as helpful.
