ISTJ
The Logistician
The reason things actually get done. Not just planned — done.
How they think
ISTJs think in facts, precedents, and proven methods. They remember what happened last time, cross-reference it with what's happening now, and quietly arrive at the sensible conclusion while others are still debating. They trust what has worked over what sounds interesting.
