For people whose personality types are dominated by Decision Making functions, (i.e. Thinking or Feeling), their ideal partners will include both Sensing and Intuitive types. Many people have problems communicating effectively with people who do not share their same preference for Information Gathering. So, if you have a very strong preference for Sensing or Intuition, you will need to give the personality type with the same preference a higher value as a likely natural partner. For example, an ISFP who strongly prefers Sensing will work best with an ESFJ, rather than an ENFJ.
