Abstract
Data on polarized lepton-proton scattering are shown to give no clear conclusion on the spin content of the proton. We argue that errors have been underestimated, specifically those arising from the uncertainty of the extrapolation to infinite energy (x→0). Estimates of the spin content are sensitive to such uncertainty and possible ways of surmounting this problem are discussed.Keywords
