When we turn to the second part of this principle for institutional choice (the important requirement that goes by its own name of 'the Difference Principle'), we have to examine how the different potential institutional arrangements would mesh with, and interact with, behav¬ioural norms standard in the society. Indeed, even the language of the difference principle reflects the involvement of this criterion with what would actually happen in the society (that is, whether inequal¬ities will work out to be of the greatest benefit of the least-advantaged members of society'). Again, this gives Rawls much more room to build in sensitivity to behavioural differences.
