Is George W. Bush an example of a person who, despite having a high IQ, isn't very smart? New Scientist contributor Michael Bond certainly thinks so:
"Bush's IQ score is estimated to be above 120, which suggests an intelligence in the top 10 per cent of the population. But this, surely, does not tell the whole story. Even those sympathetic to the former president have acknowledged that as a thinker and decision-maker he is not all there."
The silly Bush bashing detracts from what is actually quite a good article examining IQ and good thinking - a high IQ not guaranteeing good thinking. Read the whole thing.
Attached to the article are three seemingly easy questions that are actually a bit tricky - only 17 percent of those tested got all three right. I'll post the answers later so you know how you went.
1) A bat and a ball cost $1.10 in total. The bat costs $1 more than the ball. How much does the ball cost?
2) If it takes five machines 5 minutes to make five widgets, how long would it take 100 machines to make 100 widgets?
3) In a lake, there is a patch of lily pads. Every day, the patch doubles in size. If it takes 48 days for the patch to cover the entire lake, how long would it take for the patch to cover half of it?
Answers: 1. five cents 2. five minutes 3. 47 days
