I prefer the knife anyhow
Seriously though, I meant it as a discourse not a witch hunt, hence the forewarning apology.
I disagree not in that you have trances, okay that does give me the heeby geebies, but more so that the claim to be able to alter type is, in my considered opinion, hogwash. The reason being is that you experience things through your cognitive wiring yes? (even if you don't like the MBTI's translation of it, you agree that such things exists yes?) Well then if so and you are an ENTP for example, then your ISTP will be an ENTPs take on an ISTP and not a person who has grown and developed as an ISTP. Ergo you aren't being an ISTP, just trying to think like one.
Don't get me wrong, I admire the ideal. Seeing things from another perspective is something I rate highly as a desirable attribute in a mind. I'm just not sure that the particular methodology and designs being employed are a healthy way to investigate different types.
