Because we have no evidence that such is the case on a culturally grouping level.
There is no genetic concept of "Chinese". It literally doesn't exist.
You're making this about the possibility of genetics impacting behavior, when the real issue is you thinking cultural boundaries exist in genetics. They don't.
If you go low enough on any topic the boundaries between categories become vague and the definitions become extremely complex. It's very hard to define what a human is in terms of atoms. The same goes for race, it's very hard to define, at the genetic level what is chinese, and what is not, but the category and boundary exists at all levels, and we can't ignore it.
I've heard of your argument before. They say that the delta in genetic differences between two people of different races is the same as the delta of two people, of the same race, therefore race doesn't exist. This argument is flawed. I believe the "genetic" definition of race is immensely more complex than simply the delta of genetic differences. Here's a more accurate definition: People of the same race have a higher probability of sharing certain genetic traits.
So let me redefine my argument in way you can understand. The people who we label as "chinese" who share similar physical/genetic traits, I believe will be more likely to also share a behavioral genetic trait that makes them more likely to cheat.
Common misconception that they do, but there is very little genetic consistency across cultural boundaries, and when such a thing does exist, it's quite noteworthy.
This statement is utterly and completely incorrect. It is a common myth in the social sciences.
Please read: http://en.wikipedia.org/wiki/Race_and_genetics#Population_ge...
first paragraph from above page: "The relationship between race and genetics is relevant to the controversy concerning race. In everyday life many societies classify populations into groups based on phenotypical traits and impressions of probable geographic ancestry and socio-economic status - these are the groups we tend to call "races". Because the patterns of variation of human genetic traits are clinal, with a gradual change in trait frequency between population clusters, it is possible to statistically correlate clusters of physical traits with individual geographic ancestry. The frequencies of alleles tend to form clusters where populations live closely together and interact over periods of time. This is due to endogamy within kin groups and lineages or national, cultural or linguistic boundaries. This causes genetic clusters to correlate statistically with population groups when a number of alleles are evaluated. Different clines align around the different centers, resulting in more complex variations than those observed comparing continental groups."
In short it's saying genetic traits can be statistically correlated with population groups (race) but variations of traits that are different within population groups can actually be more complex than those observed when compared with people outside of their race.
This is literally exactly my argument. Supported by wikipedia at the very least.
What we "tend to call" race is not defined, despite this wiki page's attempt to do so.
It isn't. The concept of "race" is not rigorously defined.
http://en.wikipedia.org/wiki/Life#Definitions
A word not having a rigorous definition means it cannot be discussed scientifically. Hence the actual problem of studying the existence of life, e.g. is a virus alive?

>A word not having a rigorous definition means it cannot be discussed scientifically.
Life is discussed scientifically in many contexts yet it is not unequivocally or rigorously defined. In fact there's an entire field based on the study of life. It's called biology, aka the study of life. If a scientific field can stem from a word that does not have a rigorous or unequivocal definition, then it can be discussed scientifically.
I'm getting pretty tired too. You choose not to accept the facts even when a scientific description proving my point is thrown in your face. Ideas need evidence for support, you have presented me with ideas, but no evidence.
The folks in the field are in agreement with me, (see the old wikipedia link I sent you). You got nothing, only empty claims.
It's very possible for many differences in behavior between races to be genetic in origin, in fact it's the more logical hypothesis versus the alternative which states genetics doesn't influence behavioral differences between races.
Think about it. If genetics influences physical traits from height, skin color, facial features, and even athleticism, what black magic in this world makes it so that genetics doesn't even touch behavior or intelligence?
>It's hard to imagine a protein causing such complex differences in behavior while affecting nothing else.
It's impossible to logically deduce a conclusion from the bottom up. We simply currently don't have enough knowledge to know how proteins scaffold the entire human neural network. With highly limited knowledge, we can only look at the problem from the top down. That being: genetics is known to influence physical traits, therefore it is logical to conclude that it also influences mental traits.
