Pre-registration is a pretty big one: essential you outline your research plan (what you’re looking for, how you will analyze the data, what bars you are setting for significance, etc.)
before you do any research. You plan is reviewed and accepted (or denied), often by both funding agency and journal you want to submit to,
before they know the results.
Then you perform the experiment exactly* how you said you would based on the pre-registration, and you get to publish your results whether they are positive or negative.
* Changes are allowed, but must be explicitly called out and a valid reason given.
