Shortcut citations in the methods section: Frequency, problems, and strategies for responsible reuse

Methods sections often lack critical details needed to reproduce an experiment; the practice of citing previous papers instead of describing the methods in detail may contribute to this problem. An analysis of >800 papers across three fields shows that >90% of papers use at least one shortcut citation, that these significantly impair reconstruction of the original method, and that <25% of journals have policies relating to previously described methods.
