When someone interested in Myers-Briggs®talks about loops, they’re referring to what happens when a person bypasses their co-pilot function and starts relying on their dominant and tertiary process instead. This can be a temporary situation, or it can last for quite a long time depending on the individual and their circumstances.

Some people teach that the Dominant-Tertiary Loop leads to personality disorders, but I have not found any good research to back up this claim. We can slip into a loop pattern without developing a disorder, and specific mental illnesses aren’t tied to any one personality type. It seems more likely to me that, as a general rule, loops are part of a reaction to stress or an attempt to avoid discomfort.

We all need a balance between inner and outer world feedback, a way to learn new information, and a way to process information and make decisions. We’re got all that covered in our dominant and co-pilot functions because one is introverted and one is extroverted, and one’s a perceiving/learning function (Sending or Intuition) and one’s a judging/decision-making function (Feeling or Thinking).

When we skip our co-pilot function and go for the tertiary instead, we’re replacing the co-pilot with a function that fills a similar role because the tertiary and co-pilot are both either Perceiving or Judging functions. However, the tertiary has the same orientation (Introverted or Extroverted) as the dominant function. Going into a “loop” means we’re ignoring the world that is most uncomfortable for us and we’re opting to use a function that’s less mature than our co-pilot. This “loop” is going to look different for each type, but in all cases it means we’re not balanced. It also usually means that we’re avoiding personal growth. Read more →
