A flawed study on deworming children—and new studies that expose its errors—reveal why activists and philanthropists alike need safeguards.
The book Zen and the Art of Motorcycle Maintenance, of all things, offers a critically important message for people who work in development and philanthropy. “The real purpose of the scientific method is to make sure nature hasn’t misled you into thinking you know something you actually don’t know.”
Three new papers published today confirm this, by illustrating just how easily we can be misled by what we think we know, and just how much the power of the scientific method can safeguard us from continuing to be misled (and potentially investing significant time and effort on the wrong priorities). That’s because the three papers raise important questions about the practice of treating children for intestinal worms, which, in recent years, has become a darling of international development.
