Studies with fewer than 1,000 samples are not very meaningful.

[dhosek]

Assuming your samples are not biased, 1000 subjects are generally far more than are necessary to demonstrate an effect. People who complain about sample size are generally not that well-educated in statistics.

A well-educated person in statistics would also mention that it requires a certain class of distribution. This is one of Nassim Taleb's favourite subject (imagine computing the average net worth of a random group of people and suddenly Bill Gates is among them)

Which would become a biased sample. It’s not as if nobody doing statistical analysis has never seen outliers before.

A sample size of 198 as per this study is more than sufficient to draw pretty strong conclusions.

The issue is not the sample size, it's that studies like these almost always involve a very homogenous population of young college students.

I don't know for sure, but my own anecdotal experience is that yes, there most certainly are challenges when a person from one culture assesses the intelligence of someone else from another culture.

It would be nice to know whether this is supported by scientific evidence, or whether this is simply my own personal bias at play.

Also not replicated that I can see.
