I know this is a weird thinking, still I am curious. Most members of this forum would agree that the types we are talking about exist in real life. They are visible enough for us to be able to exchange thoughts about them.
The types we are talking about differ by using different dominant functions. These functions have all to do with gathering information and coming to decisions. So clearly they have to do with what our brains is supposed to do. Therefore we should be able to find correlates of those functions in our brain. Having read some neuroscience books myself I know you can’t allocate specific functions to a specific region in the brain. Still don’t you think that discoveries in neuroscience might be helpful to explain those eight functions? E.g. could the somatic marker theory by Damasio tell us something about introverted feeling?
Would it be wrong to say those functions don’t exist if neuroscience is not able to explain them?
PS: I am happy if you move the thread to the more appropriate forum.
