In socionics there is no big G but Gulenko (as,) haven't you heard? But mostly, it's because he's famous and people bandwagon with famous people regardless of how correct or incorrect their ideas are. Clearly what Gulenko has been doing is no good because you can call anyone you want an IEI-N if you started the conversation and they didn't, clearly a dominant type with more Se would start the conversation, even though people starting conversations on DCNH mostly just repel anyone who dislikes the undue emphasis on DCNH and that's NTR.
