Still, skeptics like might have 1000 reasons why it won't work, such small studies could reduce the 1000 to a smaller number. If the study would have failed you would probably be happy and not argue that it was not correct and we should do it on a full country. If the study fails we give up, then if it does not fail we can try new larger studies.
