Hi there – someone who's worked on NIH (NIMH) funded projects. Our primary interest is in being transparent and reproducible. NIH has supported this for a long time – e.g. pushing people to post deidentified datasets online in central repositories. Since it's also good practice to provide your code in a reproducibility package, there is, literally, nothing to hide.

Recent MAHA-era large-scale funding opportunities have embraced this as "gold-standard science", and explicitly require separate reproducibility teams.
