We investigated the acceptability and frequency of the use of cognitive enhancement (CE) drugs and three different types of academic misconduct (plagiarism, cheating in exams, and falsifying/fabricating data). Data from a web-based survey among German university students were used. Moral acceptability was relatively low for CE drug use and moderate for academic misconduct, while the correlation of their respective acceptability was moderately weak. Prevalence of CE drug use was lower than for academic misconduct and (very) lightly correlated with the prevalence (...) of plagiarism and fabrication/falsification. Acceptability of the investigated behaviors was associated with higher prevalence rates of each behavior. (shrink)
