Recent research has identified spirituality as an important contributor to vaccine scepticism and low faith in science, particularly in WEIRD (Western, Educated, Industrialized, Rich and Democratic) nations. In the present study, we further tested the generalizability of these findings in a religious South-Eastern European country - Greece, with more extensive measures of key constructs. We replicate previous work using measures of improved construct validity. Spirituality was found to be the strongest predictor of vaccine scepticism and low faith in science. In addition, low science literacy was also predictive of vaccine rejection. Climate change scepticism was not associated with spirituality but with political conservatism, which corroborates previous findings. These results provide further evidence for two previously made observations: science scepticism is heterogeneous, and spirituality is an important factor in shaping science rejection.
