The MBTI classifies into 16 personalities. Today, we'll be talking about the most common personality type, the ISTJ personality type, which is made up of approximately 13 percent of the population. ISTJ stands for Introversion, Sensing, Thinking, and Judgement and people with this personality type are known as the “Detective” or “Logistician”.
