When it comes to forum typings, it seems that the ones which are easiest to type, or where there is a general forum consensus, is that Beta types are the ones most easy to type/identify.
There has been as I recall, a lot of Delta typings which have been and still are called into question, and in Alpha, INTj seems a difficult one to type..ie is Hitta INTj, is UDP, Carla an INTj etc.
And in gamma..the typings of INTp's such as Phaedrus, Crazedrat (who are the only regular self typed INTp's that I can think of) have been frequently called into question.
I don't think anyone who says they are Beta, or really anyone in Beta have their type doubted, at least vast majority, if not all?
I wonder if anyone has any ideas why that is? Are other quadras and some types harder to identity, or is Beta easier to type, or easier to place people in?
