So come on, how does this accident suggest that asian people have "more of a problem with losing face than the rest of us"?
OMG, once again you have missed the point. Your answer - this one accident doesn't, it was suggested as a starting point. I'll say it again - it's a trend, like the difference between weather and climate. Do you get it now? No one accident is ever going to prove it, especially since our friend Mr. Reason stated there's never just one cause for an accident. Or did u miss that too?
As Mr. Hat stated, many cross culture CRM studies have been conducted. They also notice problems with those of Western culture, such as getting restless with repetitive tasks, inability to do something the same way 100 times (ie trying their own way because there "must" be a better way to do this") and more likely to become slack between checks (ie flying differently when someone is watching).
Like I said before and I'll say again, go and do your research.
