Definitely not true in general.  If I wanted to know the gender ratio at
the latest OLS I'd take the results from a sample of a dozen chosen
randomly over the results from a sample of hundreds all taken from the
men's room.

For exactly the same quality of sampling, yes, the larger the better,
but the point of diminishing returns comes pretty quickly.  So given
limited resources it's probably more important to work on the quality of
the sample rather than on its size....
