We are getting less alike, not merging into a single, mixed humanity

I think INTJ's are branching off!.... :stunned:

At the end of the day I see more and more mixed race couples around me, proving that racism is finally starting to be ignored. What interests me most in this interact is that mixed race dating is don't more in the cities and less accepted in small towns, so this leads me down a trail that begs the question: as we progress further and further will the case be that cities will have a higher mix ratio than people in smaller towns? How would this situation play into your intj theory?

I'm sure cities have higher concentrations of thinking/intuitive types, due to cities being the center of commerce and finance. A good way to test the personality/genetics correlation would be to get a bunch of people that strongly identify with their personality types, and then compare their genes to look for similarities or differences (mostly in genes involved with brain development i'd assume) I want to stress that this isn't a INTJ specific theory, just that thinking/intuition types are evolving along a different path than sensing/feeling types

qwery, I live in a "big" city and around here there is a high degree of polarization - mixed-race couples are rare and are definitely looked down on. I'm certain that this is an anomaly for this city (which has been called one of the more racially segregated metro area in the US). I also spent 3 years in Ft Wayne, IN - not what one would call a "major" city. I saw more racially-mixed couple there than I ever have. And that was not limited to the city, but it seemed to be well accepted way out in "the boonies" as well.

I think that your theory may be generally true, but not uniform throughout the US (and perhaps not the world?).

I think the personality types existed for a while, but there might be less of us INTJ's back then since it was all about comform and obedience. INTJ might be independent, but they are not totally different from the other types such as ISTJ and ENTJ. When I was reading their profiles (simply because sometimes I tend to get these two results), I realized that we're not so different. Sure, we're not the same. I think similar is the word to describe the three types.

Is there a catch all term for those 3 types? I've noticed the same thing. I was wondering if there was some kind of grouping terminology...

[Hypomanic]

Yeah, ISTJ's rock.. my mom's an ENTJ too... she's quite different from my INTJ and ISTJ friend though, fyi.

Personally I don't get where personality theory leads into this.

The reason humans are evolving faster is because we have *such* a wide range of different habitats we're adapting differently to them. And culture also helps that too. But we're evolving to fit on separate continents. The earth's land mass used to be closer. Now it's more spread out so humans can be more different to help survive their specific areas the best.

Do personality types help you survive your climate? I'm not so sure about that. Unless one type gets a significant advantage at reproduction compared to others or some such, then each type will reproduce and a type won't become phased out (ie INTJs don't commonly reproduce, the type gets phased out or something) Perhaps if INTJs populated x area of the world we would be different than the rest of the population. Perhaps if we were all in similar environments that would be the case. But this is not so.

Evolution works through heritable genes that can be passed on through generations in order so that their offspring can survive. The offspring with the best genes will survive. The ones less adapted won't.

rwyatt: as for Ft Wayne IN being diverse? I'm SHOCKED. Literally. The only people I've seen from there are caucasian people. Little mix at all. Generally cities have more mixed populations than to rural areas. Even rural areas will have non-mixed minority populations. In rural areas it's generally not accepted to marry another race. Inner cities it's fine.

It's not about personality types helping you survive, Darwin wasn't completely right you know. It's about reproduction based on finding mates with similar personalities. Who are you more likely to reproduce with, someone with a polar opposite personality, or one similar to your own? This the mechanism that drives evolution along personality lines. I think it may be one of the most powerful forces pushing evolution.

Not that this all means much, in about 10-15 years we will be in control of our evolution. :)

I had a problem with the statement that finding a significant proportion of the same SNP pattern along a chromosome within a lot of individuals suggests a recent evolutionary event, and rapid evolution.

The problem with that statement is that it ignores the fact that selection against changes in the DNA can also bring about that pattern. If mutations start occuring in 'housekeeping' or mandatory genes like the ribosomal genes, more often than not you are dead.

I tried to get to the article in PNAS, but couldn't. I don't discount their findings, but find them interesting, and somewhat reactionary. Because I couldn't get to the article I don't know how they suppose SNPs are evidence of evolution of genes. There is a lot of non-coding DNA in all genomes, that has no selection pressure on it. OK, I'll shut up and wait to read the article when I can find it.

Rocksteady, as far as your theory with 'who are you more likely to reproduce with.' I agree that I wouldn't consider to associate with an S. But, that is just me. Are other Ns likely to do the same, maybe, maybe not.

well, it's just a theory, and would probably take a lot of work to prove, but the assumption seems to work (until i get new data) I also have a lot to learn about genetics before I get too carried away (all the DNA talk is over my head at this point..Also, even if you were interested in an S type, you would probably want some other characteristics to match your own, I know they say opposites attract, but all i can see is conflict with certain personality types (ones that don't use logic UGH!)

although today I was reading that the birth of philosophy in ancient greece was directly related to the invention of money. Before the invention of money there were no incentives to be involved with anything except production, but with money storing value, one could focus on the more metaphorical aspects of life.. It could be that money somehow allowed us to use parts of our brain that we never used up to that point...also, those without the brain power to use money would be in a pretty difficult situation, and probably died out...which would be a pretty radical change that occurred pretty quickly.
