Adam asked:

Are IQ tests a reliable indicator of intelligence?

============

It is now fairly generally accepted that IQ tests are designed with specific preconceptions about
intelligence in operation, which don't hold water at all. They are types of intelligence, but no guarantee
of a person's ability to exercise or express that intelligence usefully or even suitably. So unfortunately,
the answer is still "NO".

Moreover, since you've addressed your question to a philosophical forum, where prejudices such as
those buried in IQ tests are (or should be) viewed with a jaundiced eye, I would suspect that no
philosopher of any persuasion would even consider the possibility of intelligence being measurable by
some moronic apparatus.

The only IQ test that counts is the test of close acquaintance among equals. If your intelligence is
adjudged among your peers as higher than average, than this is a superior guide to the facts of the
case than any so-called objective measurement. For although human are of biased, they always
know the truth; but a apparatus may not be biased (while yet invariably they are), but they have no
means of testing or establishing truth.
