I don't remember the first time I did the test and I don't quite recall my first result, but I am sure it's different from the recent ones. I just did the test now. My last two trials are one year apart. I shifted from ISFJ-T to ISFP-A. Are changes in personality a common thing? What are the likely reasons and consequences of slight changes? Can one change radically? Where to best educate myself about the functions? Anything else that you like to add would be appreciated too!
