Correct. It doesn't matter how large a sample size is if the sample is biased. This should be something that every high school student knows after any high school statistics course, but it is a crucial consideration that is widely ignored.

although we can all think of an edge case.. (especially if we know how the sample is biased)

eg: a gender survey in the general population that transgender respondees do not answer -- ends up with a 99% sample size (all but the transgenders) -- and thus gives a pretty significant bit of data on male:female ratios, etc..

Agreed in principle though.
