We have used existing data sets to make a statistical investigation of the well-accepted relationship between the power in bipolar molecular outflows from young stellar objects (YSOs) and the bolometric luminosity of the central object. While there is good evidence for a real correlation between these and related properties, we show that the slope of the correlation, in which the physics should be revealed, may be affected by selection bias in the source samples. We also use existing source catalogues to argue that correlations between outflow power (and force) and source luminosity may be the result only of the more luminous sources existing in more massive cores. Because of a lack of any correlation between outflow velocity and source luminosity, the outflow dynamics are deternined solely by the amount of mass in the outflow, which is determined by the mass available to be entrained. We may therefore be learning little about the physics of the outflow generating mechanism and arguments based on such evidence in favour of accretion-driven flows may be unreliable.
