 In recent years, the lagging of the Muslim world in science is manifest in the disproportionately small amount of scientific output as measured by citations of articles published in internationally circulating science journals, annual expenditures on research and development, and numbers of research scientists and engineers.Concern has been raised that the contemporary Muslim world suffers from scientific illiteracy.Skepticism of science among some Muslims is reflected in issues such as resistance in Muslim northern Nigeria to polio inoculation, which some believe is "an imaginary thing created in the West or it is a ploy to get us to submit to this evil agenda."
