Explanatory style from nine religious groups, representing fundamental
ist, moderate, and liberal view-points, was investigated by questionna
ire and by blind content analysis of their sermons and liturgy. Fundam
entalist individuals were significantly more optimistic by questionnai
re than those from moderate religions, who were in turn more optimisti
c than liberals. The liturgy and sermons showed the parallel pattern o
f optimism. Regression analyses suggested that the greater optimism of
fundamentalist individuals may be entirely accounted for by the great
er hope and daily influence fundamentalism engenders, along with the g
reater optimism of the religious services they hear.
