If privilege means "probabilistic causes of non-equal representation", then that's a very broad definition and every non-deterministic unequal representation is caused by privilege. But you were responding to a discussion where we were using "privilege" to mean something along the lines of "social biases unfairly favoring one group".
By definition, Asian males have 8x the "probabilistic causes of non-equal representation". It seems highly unlikely that they have 8x the "social biases unfairly favoring one group", which is what hackeruser and myself were actually discussing.
You also don't seem to be using this definition consistently. For example, if I take this comment of yours and substitute this definition in, it makes no sense:
"When you find achievement highly correlated with a cultural group, however, it is pretty likely to be a function of probabilistic causes of non-equal representation. The alternative hypothesis is that, for example, Jews are just innately better at science."
I'm beginning to think you are attempting a Motte and Bailey: http://slatestarcodex.com/2014/11/03/all-in-all-another-bric...
