I found a sample test online that is apparently used to test people's problem-solving ability, called the "Wunderlic Test." Apparently the NFL has long used this test to check people's abilities. The sample, at this web page,
seems to have a serious error in logic. Their preferred answer for problem #2 is not correct. Here's the problem:
2. Assume the first two statements are true.
The boy plays football. All football players wear helmets. The boy wears a helmet.
Is the final statement:
The correct answer (which they reject) is "Not Certain." The question SHOULD have been (to get their desired answer):
Assume the first three statements are true: The boy plays football. Anyone who plays football is a football player. All football players ALWAYS wear helmets. The boy wears a helmet.
I can't tell you - but maybe you already know - how frustrating it is to be tested on careful reasonaing ability by a test based on fuzzy reasoning.
