I realize that repeat studies are important generally in science. But, many studies (particularly health related) seem to have such a result built into their design. If you get a result, it will just be preliminary and require a larger sample study moving on.
Is there a mechanism in science for actually taking these preliminary results and validating/falsifying them more conclusively? Does a result like this make a larger scale study this team's top priority for the next study? Will these results convince another team to do the full study?
Otherwise, it feels like there's something structurally wrong. If the study is designed as a non-conclusive prototype or framework, what's the point unless it leads to other studies?
