It is evident that people behave differently if they come from different cultures. There may indeed be some different character dispositions that are not culturally that are there in some races and not others. However, it seems more evident that there may be more differences in terms of natural personality traits between two white people than between a white person and a black person. In truth, we are all the same species, we all possess roughly the same amount of intelligence (in comparison to lesser animals), we all have moral capacity (in general). I would say that most dispositions to a certain type of behaviour, defined by your ethnicity is more generally culturally not genetically transmitted.

Nobody's ever been able to find anything sweeping and definitive to my knowledge.

I mean there are some very small difference traceable to particular genes being more prevalent in a population.  For example, I remember reading that some east asians populations have a gene that causes the effects of alcohol to be actively unpleasant (causes an uncomfortable flushing sensation) and the presence of that gene is correlated with a lower incidence of alcohol abuse in those populations (I can track down the reference if needed).  But nobody's ever observed anything in humans like the differences between the behavior of dog or cat breeds that I'm aware of.

...and not that people haven't been looking.  I mean, the Bell Jar guys were trying to find IQ correlations, but I believe the last I heard their data had been debunked. 

It's extremely difficult to build a genuine scientific basis for conclusions like "low testosterone = obedience."  Evolutionary psychologists and cognitive psychologists are the legitimate scientists who deal with these kinds of questions, and you'd pretty much never hear a serious scientist making that kind of claim.

For one thing, the hormonal interaction with behavior is not directly causal.  It's more of a feedback relationship, so that, for example, the alpha male of the monkey troop has the highest testosterone, but if you take him out of the group, whichever male rises to become the alpha male has a corresponding increase in testosterone.  So the social status and the hormone levels cause each other at more or less the same time.  Hormones are also very subject to measurement errors because they fluctuate so broadly and quickly.  That's why scientists who work with hormones usually talk in terms of correlations (like in my example of Asians and alcohol above).

Most of the theoretical evidence on brain structures is still being accumulated, but it looks like something similar: brain structures influence behaviors, but behaviors and environment can also have an effect on brain structures, within limits.

But mostly it's just insanely hard to control for environment where humans are concerned.  Twin and adoption studies only go so far.  So legitimate science has to take small steps and design experiments very carefully. 

...and of course the experiment that hasn't been done by people who say "group A has more hormone X than group B" is whether or not any randomly selected group will tend to have some kind of detectable tendency like this.  That is, the detected difference might not be due to race at all, it might just be a coincidence. 

Having said that, there's a lot of pseudoscience and misinformation out there surrounding differences between races. There's a looooong tradition of Western European types using pseudoscience to "prove" that the "darker" races are inferior in order to justify exploitation and other kinds of bad behavior. The book I mentioned, The Bell Curve, is just the latest incarnation of this effort.

So evidence is evidence if it's genuine, but bring your skeptical hat along every time somebody starts to push the agenda of genetically-inherited racial behavior differences.

Why waste your time?  The assholes on stormfront make me regret that I am a human being.  It literally makes me feel really bad that theu belong to the same species as me.

Don't get pissed at them, its not worth it.  Be apathetic toward those social degenerates.  They have the mental capacity of a 5 year old.  There ideas need to be marginalized, in the same way we marignalize the delusional persons delusions 

You need to do legitimate scientific research my friend.  This is 1920's eugenics nonsense.  It was discredited over 60 years ago.  There is not one piece of scientific evidence that suggests that there is such a thing as "race."  At least not biologically.  Race is a socially constructed idea...it has no reality outside the minds of bigots.  It is a biological fact that there is more variation within a population that with a member of another population.  In other words, you and your neighbor has more genetic variation than you an a man from africa.  

Race is, quite literally, skin deep.  End of story.  The skulls of whites are not bigger than blacks.  Don't trust me, however, go ask anthropologists and geneticists if race has any biological merit.  They will say no.

Hell, ask Yellow #5.  He is a biologist.  He has backed me up many times making this point.
