This is just a question I thought I would ask because I don't understand the connection between functional and personal development over time as well as I probably should: How might immaturity manifest itself differently with regards to each of the types/dominant functions? What are the consequences?
For instance, what does ESFP immaturity look like when compared to ESTP immaturity? What does an immature Ti dom look like and what are the challenges of dealing with immature Ti? How might a person deal with an immature INFP versus an immature ISFP? Should one just try to engage their auxiliary function?
For that matter, is immaturity largely marked by overreliance on the dominant function - and is balance among the first few functions the hallmark of maturity?
To what extent does maturity/immaturity make it easier or more difficult to type someone? If maturity is balance, are functionally balanced people necessarily a greater challenge?
These are just examples. I realize that this is kind of a broad question, so feel free to contribute anything you think is relevant or that you would like to share.
