> including more funding for larger studies You won't find any experts to disagree with you on this part.
In many cases it's scientists who decide if existing funding is used on many small studies or few large ones, and which studies in particular. In that sense it is important to evaluate if maybe having fewer studies with better statistical significance would be better.
In my experience it works out more like, scientists make their studies as big as funding will allow for while tracking and justifying every single expenditure to your grant providers who can withdraw funding if they're not happy with the way their money's being used.
