As many as 200 academic papers on COVID-19 have been retracted since the start of the pandemic due to reasons ranging from calculation errors to missing evidence to fraud.
- The flaws were especially egregious in many early studies declaring the effectiveness of therapeutics like ivermectin or hydroxychloroquine—papers which were eventually deemed problematic.
- Retractions don’t fix the damage done by the faulty studies: even small-scale papers can have “strong influence on broader conclusions about COVID-19,” and confusion around retractions adds to “inflaming our all-consuming culture war.”
- The problem speaks to the need for more guardrails around—or even a total overhaul of—the peer-review process, some researchers say.
