The occurrence of superconductivity in doped SrTiO<sub>3</sub> at low carrier densities points to the presence of an unusually strong pairing interaction that has eluded understanding for several decades. We report experimental results showing the pressure dependence of the superconducting transition temperature, T<sub>c</sub>, near to optimal doping that sheds light on the nature of this interaction. We find that T<sub>c</sub> increases dramatically when the energy gap of the ferroelectric crit ...[more]
