[From the article “Cancer scientists are having trouble replicating groundbreaking research” from the Vox website] “Replication has emerged as a powerful tool to check science and get us closer to the truth. Researchers take an experiment that’s already been done, and test whether its conclusions hold up by reproducing it. The general principle is that if the results repeat, then the original results were correct and reliable. If they don’t, then the first study must be flawed, or its findings false. But there’s a big wrinkle with replication studies: They don’t work like that. As researchers reproduce more experiments, they’re learning that they can’t always get clear answers about the reliability of the original results. Replication, it seems, is a whole lot murkier than we thought.” To read more, click here.
