Socionics is a theory of induction, which is about making generalizations from observations, which is wrong, because that's just not how science works (hint: science is about coming up with explanations, through deduction).
So here's all the amazing things that might be happening at the Socionics lab with all the amazing Socionists to come up with this theory, complete with translations of what they really mean.
Socionist: Look at this video here, and this person, he is showing his emotions, this is Fe.
Translation: "Durr, as if anyone with half a brain couldn't simply OBSERVE that he is showing emotions. But since I'm so totally stupid, I will call it "Fe" for no reason other than to confuse you".
Socionist: And here, did you see that? Look at how he suddenly came up with connections, how he sees into the future! This here, is called intuition. It's like magic!
Translation: "Durr, I'm too stupid to come up with a possible explanation or a theory on how this "intution" actually works, so I will simply call it "intuition" from now on for things that I simply do not understand or cannot explain, since I'm totally stupid and hate science".
Socionist: Wow! Look at this SLE here, look at how graceful and forceful her movement is! This here, is called Se.
Translation: "Durr, I'm going to be making even more brain-dead observations which will bring no further insights at all, because I'm totally stupid. I'm gathering all these observational data to come up with my own 'theory', which is wrong, because that's just inductivism, and totally forget that I have come up with the WHY of things and offer no explanations, since I'm totally stupid"
And so on.
