I disagree. "A year of education" is mostly about gaining knowledge. It's obvious that air pullution can't possibly make you forget one year of such knowledge, and I have no idea in what other intuitive way this can be interpreted that makes any sense to the average person. If it's meaningfull to someone then it's only because he understood it wrongly.

Is it? What people remember of one year of education is probably very little to begin with and it only gets less over time; it doesn't seem unbelievable that pollution could cause those memories to decay faster.

Well if that seems plausible to you then it's only further proof of how misleading the wording is, as the actual study makes no claims about people forgetting a year of education.
