Second, the quote reminds us of something more fundamental: 'evidence' is, essentially, a contested concept. Evidence and expertise are often invoked to provide a neutral, rationalistic and technical underpinning of public policy, but although evidence and expertise may seem neutral, in fact, they are not. What constitutes 'evidence' and what counts as 'objective' , 'scientific' or 'expert' knowledge is a philosophical question, rooted in the Philosophy of Science. Most 20 th century philosophers of science took a normative approach to the question: providing answers as to what Porter's work on the rise of quantitative knowledge to achieve 'objectivity' in science and public life shows how public accountability and epistemic ideals were mutually constitutive in the historical setting of the 19 th century. Porter demonstrates how statistics, numerical facts and figures have become a means to achieve objectivity and public trust in modern scientific, professional and public life. 'Trust in Numbers' invites us to take a closer look at knowledge practices and to understand the forms of trust and accountability that are constituted in them. suffers an 'intelligibility deficit' (Coady, 2010, p. 110). As an example Fricker recounts the situation of Carmita Wood, who suffers sexual harassment prior to the time when we had this critical concept: 'so she cannot properly comprehend her own experience, let alone render it communicatively intelligible to others' (Fricker, 2007, p. 1). This is considered a form of injustice, because someone who cannot make him/herself understood is unable to perform social and political tasks that demand their intelligible contribution. Someone who suffers a lack of conceptual resources to make him/ insurance (for low-income and middle-income groups), and private health insurances (for those above a certain income threshold) (Helderman et al., 2014). Faced with growing budget problems in the 80s, the lack of incentives for efficiency and innovation within the Sickness Funds system raised concerns, leading to growing support for 'incentive-based reforms and a reconsideration of the role of competition' (Van de Ven & Schut, 2008). Since the 90s successive governments worked to install all conditions necessary for managed competition in the health care system. In 2006, these efforts culminated in a major market-oriented reform within the context of a social health insurance system: the Health Insurance Act (Zorgverzekeringswet, Zvw). The introduction of the Health Insurance Act entailed a transition from government regulation of social health insurance taken out of wages (Sickness Fund system) towards a system of regulated competition between private insurance companies. clinical science can determine 'what works' and parameters based on these scientific findings can form an 'objective' standard for provider behavior (Tanenbaum, 1995, 2012). The epistemic practice of EBM has become pervasive in decision-making at macro-, mesoand micro-levels of the Dutch health care arena since the 1990s (Bolt, 2...
