what is reproducibility crisis?

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.

I of IV: what is reproducibility ?

Published scientific studies can motivate research, inspire products, and inform policy. However, recent studies that examined dozens of published pharmaceutical papers managed to replicate the results of less than 25% of them — and similar results have been found in other scientific disciplines. How do we combat this crisis of scientific irreproducibility? Matt Anticole investigates

III of IV: Is there a reproducibility crisis?

Reproducibility is a hot topic in science at the moment, but is there a crisis? Nature asked 1,576 scientists this question as part of an online survey. Most agree that there is a crisis and over 70% said they'd tried and failed to reproduce another group's experiments.

Iv of IV: what causes replication problems?.. using stats.

Replication (re-running studies to confirm results) and reproducibility (the ability to repeat an analyses on data) have come under fire over the past few years. The foundation of science itself is built upon statistical analysis and yet there has been more and more evidence that suggests possibly even the majority of studies cannot be replicated. This "replication crisis" is likely being caused by a number of factors which we'll discuss as well as some of the proposed solutions to ensure that the results we're drawing from scientific studies are reliable.
