The results of many studies on psychology and sociology can not be reproduced and could be forged

Of the hundreds of studies, only half of them were able to reproduce the results.

A group of researchers of the project "Reproducibility" chose a hundred of more than two thousand sociological and psychological research and reproduced them. Similar to the original works, the results were obtained only in half of the cases, reports TASS .

Thus, the authors of the original works violated one of the main requirements for research and publications - reproducible results. Ideally, the study should be conducted in such a way that when it is fully reproduced, using the same initial data and methods, the verifiers would get exactly the same result.

The participants in the results verification study selected hundreds of more than two thousand scientific papers published in three leading scientific psychological journals in 2008. The study was conducted from November 2011 to December 2014.

As a result of the test, a group of 270 scientists (in the photo above is not the whole team, but only a small part) all over the world came to the conclusion that statistically insignificant as well as unexpected results are the most difficult to reproduce. In the course of its work, the group worked closely with the authors of the original publications in order to accurately repeat their research.

At the same time, inspectors are trying to justify colleagues. According to them, the irreproducibility of the result does not mean that there is a mistake in the work - the psychology is very subtle in this area, the scientific field and the difficulties in repeating the research and obtaining the same results exist.
