Today the Washington Post has a big story on efforts by the coal industry to get public schools to teach positive things about — you guessed it — coal. The impetus for the article is no doubt a recent kerfuffle over education mega-publisher Scholastic sending schools free copies of the industry-funded lesson plan “The United States of Energy.” Many parents and environmentalists were upset over businesses putting stealthy moves on kids, and Scholastic eventually promised to cease publication of the plan.

Loaded curricula designed to coerce specific sympathies from children, however, hardly come just from industry, as the Post story notes. Indeed, as I write in the new Cato book Climate Coup: Global Warming’s Invasion of Our Government and Our Lives, much of the curricular material put out at least on climate change is decidedly alarmist in nature, and is funded by you, the taxpayer. In other words, lots of people are trying to use the schools to push their biases on your kids, which is an especially dangerous thing considering how unsettled, uncertain, and multi-sided so many issues are.

In light of the huge question marks that exist in almost all subjects that schools address, the best education system is the one that is most decentralized, in which ideas can compete rather than having one (very likely flawed) conclusion imposed as orthodoxy. And it would be a system in which no level of government — either district, state, or federal — would decide what view is correct, or what should be taught based on the existence of some supposed consensus, as if “consensus” were synonymous with “absolute truth.” What is truth should not be decided by who has the best lobbyists or most political weight, nor should children be forced to learn what government simply deems to be best.

Of course, there are some people who will decide that they are so correct about something that it would be abusive not to have government force children to learn it. If their conclusion is so compelling and obvious, however, no coercion should be necessary to get people to teach it to their children — it should be overwhelmingly clear. More importantly, if there is controversy, efforts to impose a singular view are likely to fail not just with the children of unbelievers, but for many of the children whose parents share the view. As significant anecdotal evidence over the teaching of human origins has stongly suggested — and new empirical work has substantiated — when public schools are confronted with controversial issues, they tend to avoid them altogether rather than teach any side. In other words, efforts at compulsion don’t just fail, they hurt everyone.

Educational freedom, then, is the only solution to the curricular problem. If you want full power to avoid the imposition of unwanted materials on your children, you must be able to choose schools. And if you want to ensure that your kids get the instruction you think every child should have, everyone else must have that ability, too.
