'I have faith in science and in God': Common sense, cognitive polyphasia and attitudes to science in Nigeria.

This study, of modern common sense in Nigeria, combines questionnaires and interviews to examine the compatibility and incompatibility of religion and science. Nigeria is a large country with a complex diversity of religious, ethnic and cultural practices that condition the reception and elaboration of science in everyday life. We find evaluative attitudes to science structured as 'progress', 'fear' and 'mythical image'. Scientific knowledge and religiosity have a direct bearing on expectations of progress and feeling of fear and worry about science; mythical image is independent of this. Nigerians trust both scientific and religious authorities in contrast to other social actors. Many of the results are consistent with the hypothesis of cognitive polyphasia of scientific and religious knowing manifesting as a 'hierarchy', when one form is elevated over the other; 'parallelity', when both serve separate functions; and 'empowerment', where one enhances the other.
