You're such a T-lead type, yeah I still think LSI works fine for you with Ne PoLR.
You almost sound like Te-lead but I don't see Ne so I'll stick with LSI
I see.
Actually there is two tests at that page, the original basic and the extended test. The former doesn't contain photos. I'm not sure that in the extended test the photos are even used to determine type, it might just be data collection to see how different types pick photos. I have never seen anything on the site that clarified the purpose of the photos section.
As I said before, I think the two theories are not compatible but not fully different either. The switch from ENF to IST would be possible going by functions if you had weak dichotomy preferences to begin with. I recall only your J preference is certain, right?
