This is because SP types are good at just accepting the connections their Ni fills in.
What they aren't good at is consciously mulling them over, discussing them, etc.
In fact, I think doing so often almost provokes some kind of anxiety in them.
Makes them start trying to do things to pull them back into the Se world.
Questioning the source of their interpretations is antithetical to Se.
They need to immediately accept as true what it is they see.
