get the idea that the tests are somehow measuring "intelligence,"
But IQ tests do measure intelligence, and do it well. It cannot be perfect, because there is no one simple definition.
IQ does not measure education or general knowledge, which your "ignorant public" may equate with intelligence, but a more scientific version of it.
Intelligence can be far more accurately measured than other aspects of mind/personality - bravery, resilience, charisma, introversion ...
Intelligence traits (that you might define) not directly measured by IQ tests are likely to be highly correlated.
Many people do not like the idea of innate aptitudes, but wishing it false does not make it so.
Well, maybe people shouldn't be writing inaccurate headlines. Are people not allowed to criticize those?
Yes, the headline is bollocks. Welcome to slashdot :)
