This podcast explores the potential cognitive and developmental issues that air pollution can have. The best part of this episode though gets into the very clever methods the researchers employ to find natural “experiments”.
Before listening to selections from this episode it might be interesting to ask students to design a hypothetical experiment to evaluate whether the hypothesis explored in this episode is true and then listen to some of the actual methods employed to then examine why those choices were made.
Of particular interest was a research study discussed around the 26 minute mark in which a government policy in China provided an excellent “natural experiment” to help think about the impact of air pollution. Part of evaluating this topic could also be a discuss of ethics in experimentation when kids ultimately decide that a good experiment would be to pollute the environment of one group and not another to see what happens.
Air pollution is estimated to cause 7 million deaths a year and cost the global economy nearly $3 trillion. But is the true cost even higher? Stephen Dubner explores the links between pollution and cognitive function, and enlists two fellow Freakonomics Radio Network hosts in a homegrown experiment.
