How? If the majority of what determines an individuals IQ is genetic then how could it possibly have declined in the span of a few decades? Worst case scenario our predetermined genetic base line IQ is not improving as rapidly as it use to in the past.
However, I don't think there is strong enough evidence to jump to that conclusion. From what I understand a simple bad attitude can dramatically alter an individuals test score. No, I think the testing methodology and the scale of the testing would have to dramatically improve before a statement like: "People are getting dumber." can be taken seriously.
