A well-designed meta-analysis can provide valuable information for researchers, clinicians, policy-makers and the general public by summarizing years of research in a field. These analyses can be highly influential, and thus it is critical that they be performed carefully. A recent meta-analysis by Horvath, Forte, and Carter (in press) [] set out to determine whether a single-session of transcranial direct current stimulation (tDCS) affects cognition in healthy adults.
