An approximation scheme for the wave function of a few-body system is developed, in which intrinsic polarization is introduced in a natural way. The polarized wave function is tested with model three- and four-body nuclei, and it is found that two different polarizations are nearly degenerate. The resulting resonant wave function yields accurate binding energies. Furthermore, the accuracy of the spatial density is checked by means of an error-estimating principle. The result is that the advantages of simplicity and generality of the polarized wave function are coupled with very good simulation of the correct wave function.
