Socionics isn’t real

[Singu]

If you observe people long enough you will have that general sense.

You still don't know what he's going to do next, how he's going to be affected by unknown environments, what kind of experiences he will have in the future, or even how he might suddenly randomly think up of a new thing.

How often do you see people changing their minds? How often do you see people saying the exact opposite of what he was just saying before?

You might say that yes, some people are very emotional, and some people are less so. But that says little about what kind of opinions that he's likely to have.
