Dual (At least one or more preferences that fall in the middle):
The ISTJ/ISFJ: Unlike strong and moderate ISFJ’s, dual ISTJ’s with an equal preference for thinking and feeling will often come across as more mild and less abrasive. Strong ISTJ’s believe in concrete morals and values that are not subject to interpretation or change. They are traditionalists and will quietly enforce rules and regulations. Those who have a higher extroversion side will feel more comfortable expressing their opinions publicly – in person, social media, etc. Those who have a higher introversion preference are quieter about their views and tend to only vocalize their opinions if they feel comfortable. They can be stubborn and have difficulty viewing different sides of the story. It depends on the subject matter and cause that they will invest their time and energies into improving. For example if they believe in a certain social cause like Remembering the victims of 911 they may volunteer or participate to honor the people who died, joining the local Republican party society, being a deacon in church and mentoring children.
The ISTJ/ISTP will display less rigidity in activities and overall preferences in their life. For example the house does not need to be immaculate with everything in order or their clothes do not necessarily have to be perfectly folded and ironed. These are more simplistic examples and will vary from person to person. They’ll have their nuances but it will depend on personal belief and value system. For example if they feel that dessert should not be eaten first before regular food they will not be pleased when their children or other adults eat sweets before the real food. Waiting their turn in line and are not happy when others are allowed to “cut the line”.
