Alternatively, the popular press finds an article that says in this small study where this is one factor, the data suggest that (for example) caffeine may contribute to hypertension, but it would really need a larger study to validate that.
Popular press then shouts, "COFFEE CAUSES HIGH BLOOD PRESSURE!!!!"
Later study finds that caffeine CAN cause SOME increase in BP in SOME people, but that for most others, especially regular coffee drinkers, there's little or no effect.
Popular press then shouts, "STUDY PROVES CAFFEINE DOESN'T INCREASE BP".
Laymen then say, "I don't believe Science, because it keeps changing its mind!", except that there's nothing contradictory between the first and second studies.
