Scientific evaluation of social policy - is it needed?
The social services in all countries are hotly debated. No matter what level of provision is or is not made for the socially vulnerable groups within a culture, some persons regard these as totally inadequate while others see them as excessive and as waste of taxpayers' money. Neither side in this debate is at present able to produce in support of its beliefs much evidence that is sufficiently 'scientific' to withstand critical analysis. But the 'scientific approach' is now being demanded from many quarters.
