This book by Eliane Glaser is a thorough yet readable analysis of how PR is dominating business and politics, to bad effect, and calls for a return to critical thinking and to making political choices. In particular she argues that ideology is still relevant and not old-fashioned, but that these days it is skillfully hidden behind PR.
As a flavour: ‘We inhabit a political and institutional culture where a neurotic emphasis on audit and measuring outcomes is disguising the fact that facts and evidence have ceased to matter.’ (p107) Book:
