Weren't Harding and Wilson both ESI-Se? If so, then why does the sensory (sub)type vary so much between individuals and how agreeable and scholarly and conscientious they are?

Anyway, Gulenko's subtype descriptions are pretty bad. The Se (sub)type is much more easygoing on average than the Fi (sub)type and much less neurotic on average, but it's almost like there are two types within the Se (sub)type--they vary hugely in how agreeable and outgoing they are while ESI-Fi always require control and are seldom compliant to and less aware of others' wishes... the Fi (sub)type doesn't pick up on non-verbal cues as much and they have worse visual perception and memory and they're more frugal so those are some reasons they don't give people what they wish as much.

And of course, Fe really matters more for relationships than Fi base, ILE-Ti aren't worse with relationships than ESI-Fi, really... if anything, ILE-Ti are better with relationships than ESI-Fi.
