the two distributions is to be expected? Here, we explicitly resolve this question, and demonstrate that current lens samples are much too small to detect the expected differences.

Having considered the ellipticity distribution of random and lensing galaxies, it is then a natural step to investigate the impact of halo triaxiality on predictions of the quad-to-double ratio. Specifically, it is well known that the quad-to-double ratio is sensitive to the ellipticity distribution of lensing galaxies [@keetonetal97], so if lensing can bias the distribution of ellipticities in lensing galaxies, then it should also affect the predicted quad-to-double ratios. This is an important point because it has been argued that current predictions for the quad-to-double ratio are at odds with observations. More specifically, the predicted quad-to-double ratio for the CLASS [Cosmic Lens All-Sky Survey, @myersetal03; @browneetal03] sample of gravitational lenses is too low relative to observations [@rusintegmark01; @hutereretal05]. Curiously, however, recent work on the quad-to-double ratio observed in the SQLS [Sloan Digital Sky Survey Quasar Lens Search, @ogurietal06; @inadaetal07]. suggests that the exact opposite is true for the latter sample, namely, theoretical expectations are too high relative to observations [@oguri07]. In either case, it is of interest to determine how exactly does
