Not sure how seriously anyone took the original story that Internet Explorer users have a lower IQ. But if newspapers and even the BBC aren't bothering to check these 'latest research says....' stories are genuine, all the more reason to disregard them in future, I say. Next time I see a story claming 'research says mothers that do XYZ end up with children exhibiting ABC behaviour' I shall ignore it with a clean conscience.
But seriously, what lax journalism! I saw one news site which had one article saying "research proves what we already know" and the next was "stupid journalists falling for hoax", they had a very short memory!
