This why Caitlin Dewey, a blogger for the Washington Post who claims that we should praise the challenge for raising so much money, gets it all wrong. The ice bucket challenge has done one good thing, which is raise $3 million for the ALS Association. But it’s also done a really bad thing: take money and attention away from other charities and other causes. That means that, if we want to know whether the ice bucket challenge has been on balance a good thing for the world, we’ve got to assess how effective the ALS Associations is compared with other charities. If 50% of that $3 million would have been donated anyway, and if the ALS association is less than half as effective at turning donations into positive impact on people’s wellbeing than other charities are on average, then the fundraiser would actively be doing harm.
