The 2D:4D ratio is calculated by dividing the length of the second finger by that of the fourth, and issometimes employed as a proxy indication of prenatal sex hormone exposure. The current study investigatedassociations between 2D:4D and beliefs in superstitions, conspiracies, and the paranormal, in a sample of211 university students. Although no significant relationships emerged, positive correlations between 2D:4Dand paranormal and superstitious beliefs have previously been reported in the literature, implying that highlevels of prenatal oestrogen and/or low levels of prenatal testosterone may be implicated in their development.
