What is the difference in value between a $5 bill and a $20 bill? Is this difference not both real and socially constructed?
I.e. why do you assume that what is socially constructed can't be real?
The question is, really, what goes into the experience and what are the limits to the current science. If it is socially constructed, the science is limited to the current cultural context.
