Most published research is wrong, says epidemiologist John Ioannidis (pictured), author of the cult-classic paper Why Most Research Findings Are False.

But, while there are some true relationships in the world, there are also many unrelated variables that may falsely appear to be connected, WSJ’s Science Journal reports. For example, just because a person has a certain gene and gets a particular disease, doesn’t mean that the gene caused the disease.

“He has done systematic looks at the published literature and empirically shown us what we know deep inside our hearts,” said Muin Khoury, director of the National Office of Public Health Genomics at the U.S. Centers for Disease Control and Prevention, told the paper. “We need to pay more attention to the replication of published scientific results.”
