What Makes Science True? | NOVA

What makes science reliable? The ability to reproduce the results of an experiment, known as reproducibility, is one of the hallmarks of a valid scientific finding. But science is facing what many consider a reproducibility crisis, and the stakes are high. Many scientific claims cannot be replicated, and many clinical trials fail as a result.

This 15-minute video examines the reproducibility crisis and reports on the outcome of five experiments designed to test the reproducibility of cancer biology studies.

While NOVA had no editorial involvement in this video, we believe it is a thoughtful and well-researched exploration of a complex topic, and we are pleased to share it with you. The video was produced by Dakin Henderson and Kelly Thomson, and was funded entirely by the Laura and John Arnold Foundation (LJAF).

In the interest of full transparency: LJAF has an interest in this subject matter, is one of a handful of funders that supports the cost of conducting reproducibility experiments, and provided funding to the organizations featured in this video in order to carry out the reproducibility studies covered here. We have been assured that LJAF had no editorial involvement in the video.

You can also learn more about reproducibility by reviewing the following publications:
