Doing so makes it possible to verify that pupil size does not approach physiological limits (see Ambient lighting should ideally be intermediate and matched to display brightness), and makes it possible to compare effect sizes in natural units: a pupil constriction of 4 mm in response to a flash of light is in an entirely different class of effect sizes than a pupil dilation of 0.1 mm in response to a challenging calculation, even though both may be highly significant when tested statistically.
