To me is the more "particular" of all the stackings.
From what i read here from other So/Sp 4s is mainly that they are "self conscious".
I dont know if this is the trademark of this stacking... I read too that if they are 4w5 they are easily mistaken for a 5, and if they are 4w3 they look like a 3.
I had a 4w3 friend who fits in what i wrote above.
I see a lot of social criticism in them... I dont know any 4w5 with this stacking ( at least from what i noticed).They will be maybe more philosophers than artistic... But im not sure.
The other thing that i've noticed is that they develop a "counter-shame" "
or "social revolutionary" behaviour. Looking Marilyn Manson who is a 4w5 So/Sp this makes a lot of sense...
I dont know how they operate internaly, im only writing behaviours that i saw.
