The paper quotes Jensen, 1998, and says: "People with higher cognitive ability (or "IQ") differ from those with lower cognitive ability in a variety of important and unimportant ways.
"On average, they live longer, earn more, have larger working memories, faster reaction times and are more susceptible to visual illusions."
How do you think you fared?
The most common incorrect answers:
1. 10 cents
2. 100 minutes
3. 24 days
Professor Frederick continued: "Anyone who reflects upon it for even a moment would recognise that the difference between $1 and 10 cents is only 90 cents, not $1 as the problem stipulates.
"In this case, catching that error is tantamount to solving the problem, since nearly everyone who does not respond '10 cents' does, in fact give the correct response."
The correct answers:
1. 5 cents
2. 5 minutes
3. 47 days
The answers explained:
1. Say the ball costs X. Then the bat costs $1 more, so it is X + 1. So we have bat + ball = X + (X + 1) = 1.1 because together they cost $1.10. This means 2X + 1 = 1.1, then 2X = 0.1, so X = 0.05. This means the ball costs 5 cents and the bat costs $1.05.
