statement to include in referee reports:
"I request that the authors add a statement to the paper confirming
whether, for all experiments, they have reported all measures,
conditions, data exclusions, and how they determined their sample
sizes. The authors should, of course, add any additional text to ensure
the statement is accurate. This is the standard reviewer disclosure
request endorsed by the Center for Open Science [see http://osf.io/hadz3]. I
include it in every review."
