AI grant reviewers hate this one weird trick!
In some places I maintain a studied naiveté. If they like the name "gold standard" for "rigor and reproducibility", okay. I would not change all language, just tag it. "In keeping with the intention of "Gold Standard Science", we present our plans for rigor and reproducibility." Or something.

Research in rodents has enabled remarkable technical advances and deepened our understanding of brainstem circuits and general brain physiology.
However, only NHPs possess cognitive, visual, and motor faculties necessary to advance human-relevant systems neuroscience.
