Abstract: We summarize results from optical spectropolarimetry of 16 narrow-line Seyfert 1 galaxies (NLS1). Analyzed in the context of our two-component scattering model, our data show that the inclination of a line-emitting accretion disk cannot be the governing parameter, strongly suggesting that the distinctive properties of these objects have a physical rather than a geometrical origin. We also highlight the case of Mkn 1239, whose polarization spectrum reveals signatures of a powerful polar outflow, as might be expected in a source accreting near the Eddington limit.
