Even worse, according to Eric Barker:
The current investigation examines the etiology of men's errors in sexual perception after moderate alcohol use. Sensitivity and bias estimates, derived from multidimensional signal detection analysis, revealed thatmen's alcohol-influenced performance was associated with declining sensitivity to the distinction between women's friendliness and sexual interest. However, sensitivity to the distinction between conservative and provocative clothing was unaffected.
