Uncommon Descent Serving The Intelligent Design Community

John Ioannidis

When people claim that “the science” says this or that…

Discussing the recent essay by medical statistician John Ioannidis on the was politicization and shoddy research around COVID-19 are corrupting science, philosopher Edward Feser focuses on a couple of his points, including this one, “the deleterious role that social media have played.” Read More ›

Statistician Ioannidis on how COVID wrecked science

Readers may remember John Ioannidis. His point here is that getting more people involved with science doesn’t always work: "A lack of sharing and openness allowed a top medical journal to publish an article in which 671 hospitals allegedly contributed data that did not exist, and no one noticed this outright fabrication before publication."

One of those rare instances where science is self-correcting … Ioannidis is vindicated

Hey, that's good news. But what about all the people whose lives were turned upside down by the herd of stampeding buffalo otherwise known as our moral and intellectual superiors? Read More ›

The high costs of scam science

Wright: What was also not-so-novel about the COVID crisis was its origin in scam or junk science. John Ionnnidis, one of the leading critics of weak scientific work, jumped right in to alert people and policymakers about the many problems with various predictive models but he was largely ignored despite being one of the most highly-cited scientists alive. That is actually not unusual. Read More ›

COVID 19: John Ioannidis, scourge of trashy science studies, responds to critics

We still urgently need a serious discussion about the role of the “science” expert, as we survey the ruins of our economy. How is that expert different from the crystal ball reader? Read More ›

Another well-earned jab at “nutrition science”

Alex Berezow sticks another fork in nutrition science, courtesy John Ioannidis: Dr. Ioannidis has gone on to show that the best scientists don’t always get funded, why neuroscience is unreliable, why most clinical research is useless, and that most economics studies are exaggerated. In other words, the process by which we acquire new knowledge is fundamentally flawed and much of what we think we know is wrong. Dr. Ioannidis is not just a bull in a china shop; he’s a bazooka in a china shop. … Here at ACSH, we have been saying for a long time that nutrition research is shoddy and mostly wrong. The reason is inherent to the way research is conducted in the field: Too much Read More ›

Evidence-based medicine “hijacked,” says top researcher

From Retraction Watch, interviewing John Ioannidis, John Ioannidis is perhaps best known for a 2005 paper “Why Most Published Research Findings Are False.” One of the most highly cited researchers in the world, Ioannidis, a professor at Stanford, has built a career in the field of meta-research. Earlier this month, he published a heartfelt and provocative essay in the the Journal of Clinical Epidemiology titled “Evidence-Based Medicine Has Been Hijacked: A Report to David Sackett.” In it, he carries on a conversation begun in 2004 with Sackett, who died last May and was widely considered the father of evidence-based medicine. We asked Ioannidis to expand on his comments in the essay, including why he believes he is a “failure.” Retraction Read More ›
