^ This is a link to a brief talk by Michael Pierce about why some people struggle to type themselves.
I think as an INTJ (or whatever fckn type I am), subjective confirmation of type is partially acceptable and partially... not inevitable enough. Pierce's discussion of how different functions are more or less prone to buy into confirmations derivative of subjective science is really helpful to understanding why certain types have more or less difficulty typing themselves, and how malleable these conclusions are.
Type cannot be objectively confirmed. Some people have more or less of a difficult time accepting this, and some dgaf.
It's less a video that comes to any strong conclusions, and more one that sparks an interesting conversation - I'd be interested to hear anyone's thoughts on this.
