Keep in mind

Very good advice

 

I'm guessing pretty much everyone uses all 8 functions at least occasionally, and over time with a greater breadth of experience the capacity to use all functions in full would probably increase. I don't really think we need to work on it (although that couldn't hurt), it would occur as a spontaneous response.

Good point. I agree with you, utilizing our least used functions could only serve in our own best interests.

helpful elf: lol, you're right

 

After all, cognitive functions are only present approximations of how our brains actually work. Obviously there aren't 8 strict mechanisms, and things are more like blur and smoothly distributed.

My theory for now is that the Se/Ni <-> Si/Ne is developed by hormonal effects and their perception by the brain during communication; while Fe/Ti <-> Fi/Te is entirelly due to external contact, such as breastfeeding. I rely on a few sources that combine Jung and Freud, but won't go into further details yet, because I don't have enough data yet.

Both axes of perception are clearly relative, though. So they could be adapted. For example, if you were raised by super-giants, capable of all types of physical things you can't possibly do, then your Se would feel to your brain as Si. etc... We shape each other, our brains are much more complex than the way we shape them for now. On average, we don't make good use of our genes, and it's not the genes' fault. It's mostly about how the existing brains treat the new brains (and their bodies).

 

Jung also stated that we tend to work primarily on our strengths until the midlife crisis, after which point we begin to work more on our weaknesses. While development of all functions is possible, don't fret if it doesn't happen on your own timeline.

 

Thanks dude, I'm totally sick of hearing how S's are inferior to N's.
