AsPredicted.org is “a standardized pre-registration that requires only what’s necessary to separate exploratory from confirmatory analyses.” You can easily generate a short  and simple pre-registration document that “takes less effort to evaluate than it takes to evaluate the published study itself.” The form, designed by Uri Simonsohn, Joe Simmons, and Leif Nelson, has only nine questions, which are general enough that they are relevant to nearly all disciplines and types of research.
