Studies show only 10% of published science articles are reproducible. What is happening?
"Studies show a very low reproducibility for articles published in scientific journals, often as low as 10-30%. Here is a partial list:
The biotech company Amgen had a team of about 100 scientists trying to reproduce the findings of 53 “landmark” articles in cancer research published by reputable labs in top journals.
Only 6 of the 53 studies were reproduced (about 10%).
Scientists at the pharmaceutical company, Bayer, examined 67 target-validation projects in oncology, women’s health, and cardiovascular medicine. Published results were reproduced in only 14 out of 67 projects (about 21%).
The project, PsychFileDrawer, dedicated to replication of published articles in experimental psychology, shows a replication rate 3 out of 9 (33%) so far."
It's hard to exactly replicate the conditions from one experiment to the next, so the findings aren't all that startling.
