I am an INTP, and while a lot do consider Myers-Briggs as glorified Barnum statements, I do consider it somewhat valuable for self-introspection.
The main reason I don't think Myers-Briggs can be a true-ism is that each dimension is actually a spectrum. For example I am about 60% "I" (and thus 40% "E") so the various "I" true-isms only slightly factor on my personality.
