I wondered: would it be possible to use whole genome sequencing technology to determine type? If type is indeed genetic, then shouldn't it be possible to see someone's type through their genome reading? I'm not quite sure, as my knowledge of genetics is quite limited, but does anyone else have more extensive knowledge? And a question to the general population of the forum: what do you think of this?
I feel it is worth noting that as far as I know this technology is not feasible to most people due to costs. I also feel it will be a while before anyone notices a particular trend in the codes, let alone actually links it to cognitive functions.
The question raises some fun questions of its own. Of course, assuming it's true, then we'd be able to change our type through genetic engineering. Want to see what's it like to be an N or S, then go ahead. The question being are you the same person after the engineering; but that's boring. The real question being, could you change your type on demand. For work be an NT and for fun an SF. Of course, I think all of these are different ways of talking about what genetic engineering is capable of, just with a CT label; so maybe the CT is a bit irrelevant.
