Having read a study showing statistically significant correlation between an exposure and an outcome our credence of a real connection between the two increases. Should that credence remain the same when we discover that further independent studies between the exposure and other independent outcomes were conducted? Kotzen argues that it should remain the same, even if we discover the results of those studies. We argue that it can differ dependent upon the results of the studies.
