COSIG: Collection of Open Science Integrity Guides#
COSIG is a collection of expert-authored guides that aim to democratize post-publication peer review and forensic meta-science. The guides are written by domain experts and cover a wide range of topics, from image forensics and data extraction to statistical methods and plagiarism detection.
COSIG is built on four principles:
- Anyone can do post-publication peer review.
- Anyone can be a steward of the scientific literature.
- Anyone can do forensic meta-science.
- Anyone can sleuth.
