Why Has There Been So Little Progress on Alzheimer's Disease?

Stephen Dubner (host)
Show Notes

Freakonomics Radio investigates why Alzheimer's research has stalled despite decades of funding. The episode examines a major scientific fraud at the heart of the leading hypothesis that dominated the field for years, featuring interviews with the scientist who uncovered the misconduct and the journalist who broke the story. This fraud diverted billions in research funding and delayed alternative approaches.

Editorial

•
Scientific Fraud Detection and Institutional Resistance
Whistleblowers who discovered the Alzheimer's fraud faced institutional resistance before the misconduct was finally exposed.

•
Incentive Misalignment in Scientific Research and Funding
The fraud persisted partly because institutional incentives reward confirming existing hypotheses over questioning them, and because funding agencies became invested in the dominant narrative.

Contradicts

•
Fraudulent Amyloid-Beta Research Hypothesis Stalled Alzheimer's Progress
A leading Alzheimer's hypothesis built on fraudulent science dominated research funding and direction for decades, diverting attention from alternative approaches.
