In February, the White House announced its plan to put $1 billion toward a similar objective—a “Cancer Moonshot” aimed at making research more techy and efficient. But recent studies of the research enterprise reveal a more confounding issue, and one that won’t be solved with bigger grants and increasingly disruptive attitudes. The deeper problem is that much of cancer research in the lab—maybe even most of it—simply can’t be trusted. The data are corrupt. The findings are unstable. The science doesn’t work.

In other words, we face a replication crisis in the field of biomedicine, not unlike the one we’ve seen in psychology but with far more dire implications. Sloppy data analysis, contaminated lab materials, and poor experimental design all contribute to the problem. Last summer, Leonard P. Freedman, a scientist who worked for years in both academia and big pharma, published a paper with two colleagues on “the economics of reproducibility in preclinical research.” After reviewing the estimated prevalence of each of these flaws and fault-lines in biomedical literature, Freedman and his co-authors guessed that fully half of all results rest on shaky ground, and might not be replicable in other labs. These cancer studies don’t merely fail to find a cure; they might not offer any useful data whatsoever. Given current U.S. spending habits, the resulting waste amounts to more than $28 billion. That’s two dozen Cancer Moonshots misfired in every single year. That’s 100 squandered internet tycoons.
