Question: If type is genetic and not affected by environment, why do identical twins sometimes have different sociotypes?
I am not 100% sure of this fact because I don't come across one everyday but based on some forums, while a certain amount do seem uncannily similar personality-wise, a lot of twins also seem to share completely different personalities (outgoingness/introspection/and most likely type as well).
My theory is that from the moment you're born your brain constructs neural pathways that eventually become a preferred method of thinking/interpreting the world. After childhood/puberty, this pattern because permanent due to the pruning process. People with similar pathways will share the same type, kind of like the one shown in Dario Nardi's graph thingy-mabob. Fluid intelligence, proneness to certain mental disorders, amount of mirror neurons etc. play a part this process but ultimately type is not heritable.
I am extremely curious what would happen if we fully cloned a human successfully. Small differences in personality would be inevitable due to different life experience and upbringing, but if we're following this logic there's a large chance they're a completely different type, a completely different person.
I think I've posted about nature/nurture in type before, but I am still interested in new opinions lol. Anything goes.
