Another circle to be squared

Many texts lead us to believe that it is difficult to improve and optimise productivity if the prevailing culture is not conducive and not shared. Yet today I read an article by Jeff Salz (a 'cultural anthropologist;!!) who suggests that what we should be seeking is "infodiversity" - a broad range of seemingly oppositional beliefs and assumptions - to create breadth, creativity and resilience in an organisation. Are both views right?
