Siblings sharing cognitive functions

[Rickus]

Hi there
So I took a video of my younger brother, still trying to figure out his type by myself. But strangely enough I see he has similar cognitive functions to me, unless my eyes are deceiving me. I think I used to conflate personality with CT in the past so much, because I feel like me and my brother are quite different, but ironically there are moments where I can understand where he is coming from or see things from his perspective.

I suspect that he could be Unseelie, which may explain why I may feel different from him in terms of how we express emotions. Then again I find the Seelie/Unseelie aspects harder to categorize.

So my question is do siblings usually have the same cognitive functions?

From the study on twins, I assume that yes this thing could also affect siblings. Although it doesn't have to be... I think? For example, it could be that one gets F from the mother, and then Ji from the father. Or maybe it's something more hormonal and happening in the womb rather than genetic? So epigenetic? I have to say that many of our characteristics are some mix of genetics and upbringing, so I tend to want to believe that personally.
