We simply assume that the average intensity of all labour in an industrial sector will be the same as the average intensity in society as a whole. Since the labour in a sector is the average of lots of different people working at different intensities the spread of these averages will be a lot smaller than the spread of the individual intensities. It is possible that there still subsist some systematic differences in intensity between sectors. If one had some independent means of determining these then one could test to see if the intensities of labour, when added as an additional explanatory variable, increased the correlation between prices and values that one got without the correction for intensity. This would be an interesting question since it would provide a means of empirically testing Marx's hypothesis that more intense labour adds more value. In principle one could do the test if one had the opportunity to get good work-study records of the working day in different industries. I think there is a good PhD thesis in such an investigation.
