It's not bizarre, we did exactly that (to varying degrees of scientific quality) until the events of the mid 20th century.
As humans we still suck at knowing what to do with the data, we look at headline figures and not distribution graphs. If we found out tomorrow that Icelanders on average had an IQ 10 points lower than most humans we would likely see a lot of discrimination against Icelanders, even the ones on the upper end of the distribution graph that are more intelligent than the average human.
