Several lingering issues remain in the accumulated evidence presented here. Because some have recently been addressed in depth elsewhere (Morean and Corbin, 2010), we discuss them only briefly. First, it is widely understood that a failure to support a prediction is not equivalent to a disconfirmation, and this distinction is particularly relevant to the FH findings reviewed here. This meta-analysis included a relatively small number of FH comparisons on measures of stimulant alcohol effects, only four of which included assessments on the ascending limb of the BAC curve. We found no evidence of greater subjective responses among FH+ groups in any of our analyses, but this pattern does not rule out the possibility that further study will provide support for the DM under these specific conditions.
