It is sometimes stated that n{sub s} = 0.98 in hybrid inflation; sometimes that it predicts n{sub s} > 1. A number of authors have consider aspects of Planck scale corrections and argued that they affect these predictions. Here we consider these systematically, describing the situations which can yield n{sub s} = 0.96, and the extent to which this result requires additional tuning.
