In a short commentary in Nature Genetics the editors discuss how often submitted papers are flawed by an excess of claims, as if the authors wished to "hypnotize" readers with their beliefs.

But how often are such claims substantiated by experimental evidence? Attention to accurate representation of claims within a research article together with the evidence and method supporting each claim can expedite peer review. Accurate citation of the claims of others is essential to avoid prematurely closing possibly productive research strategies.

These and other issues have been dealt with in a Nature Masterclasses series of workshops.
