"Surprising" Phenomenon
Why did 10 to 20 percent of people who could easily distinguish red from green fail to report a distinction between many shades of red that the majority of people who could distinguish red from green were able to distinguish?
Objective
The correct answer will be the only answer that doesn’t help explain the phenomenon where 10 to 20 percent of people who could easily distinguish red from green failed to report a distinction between many shades of red. The correct answer must give us information that doesn’t affect our understanding of the phenomenon or information that makes the phenomenon more difficult to explain.
