There are two caveats:
1. The mothers cannot be told in advance anything about what will happen to their children, otherwise they will trigger false positives.
2. The objective is not merely to study the population-level rate, but also to engage in CIA-style experimentation whereby the experimenters try to find the few individuals that reproducibly have a substantially higher rate than of the population.
