Even dismissing all the studies that have that error, the ones left still show the same relationships, just not as quite as strong. That said, I disagree with how they aggregated the data. In fact I am not sure whether the approach they used was at all appropriate in a meta analysis. The assumptions made are reaching to say the least. I saw no control for sample size or test reliability. There may have been some evidence of range restriction as well.
Moreover the Vul, et al study looked at the literature reporting correlations between evoked BOLD signal activity and behavioral measures of individual differences in personality, emotionality, social cognition, and related domains, to quote the authors. The BOLD Signal or Functional image volumes are lower resolution scans showing measurements reï¬ecting, among other things, the amount of deoxygenated hemoglobin in the blood (the BOLD signal). The Kanai, et al study used a very different approach to the image analysis.http://www.cell.com/current-biology/abstract/S0960-9822(11)00289-2#ExperimentalProcedures So as I said, while the Vul et al study is interesting and has very valid criticisms its not relevant here.
