Response to the following :
In a small and fictitious country, a researcher has found that the higher a person lives up the big mountain, the more intelligent that individual is. Is there a problem with the researcher claiming that living high on the mountain leads to a higher intelligence quotient (IQ)? Why? What if the researcher states that this happens because people who live higher are farther away from pollution? What are some problems with the researcher's claim?
