    Science and proven experience : a Swedish variety of evidence based medicine and a way to better risk analysis?Johannes Persson, Niklas Vareman, Annika Wallin, Lena Wahlberg & Nils-Eric Sahlin - forthcoming - Journal of Risk Research.
    A key question for evidence-based medicine is how best to model the way in which EBM should‘[integrate] individual clinical expertise and the best external evidence’. We argue that the formulations and models available in the literature today are modest variations on a common theme and face very similar problems when it comes to risk analysis, which is here understood as a decision procedure comprising a factual assessment of risk, the risk assessment, and the decision what to do based on this (...)

  2. Understanding risk in forest ecosystem services: implications for effective risk management, communication and planning.Kristina Blennow, Johannes Persson, Annika Wallin, Niklas Vareman & Erik Persson - 2014 - Forestry 87:219-228.
    Uncertainty, insufficient information or information of poor quality, limited cognitive capacity and time, along with value conflicts and ethical considerations, are all aspects thatmake risk managementand riskcommunication difficult. This paper provides a review of different risk concepts and describes how these influence risk management, communication and planning in relation to forest ecosystem services. Based on the review and results of empirical studies, we suggest that personal assessment of risk is decisive in the management of forest ecosystem services. The results are (...)

    Why separate risk assessors and risk managers? Further external values affecting the risk assessor qua risk assessor.Niklas Vareman & Johannes Persson - 2010 - Journal of Risk Research 13 (5):687-700.
    The functional separation of risk assessment and risk management has long been at the heart of risk analysis structures. Equally long it has been criticized for creating technocratic risk management due to valuations being done in the risk assessment to which the stakeholders do not have access. The criticism has mostly been of an ethical nature. Arguably, in separating risk assessment and risk management, one hopes to fulfil two requirements: Social requirement: we want risk management to meet the goals and (...)

    Conclusiveness resolves the conflict between quality of evidence and imprecision in GRADE.Sten Anttila, Johannes Persson, Niklas Vareman & Nils-Eric Sahlin - 2016 - Journal of Clinical Epidemiology 75:1-5.
    The objective of our article is to show how “quality of evidence” and “imprecision,” as they are defined in Grading of Recommendations Assessment, Development, and Evaluation articles, may lead to confusion. We focus only on the context of systematic reviews.

    Ruling out risks in medical research.Sten Anttila, Johannes Persson, Måns Rosén, Niklas Vareman, Sigurd Vitols & Nils-Eric Sahlin - 2019 - Journal of Risk Research 22 (6):796-802.
    In medical research, it is not unusual that risks are ruled out without any specification the exact risk that was ruled out. This makes it difficult to balance expected health benefits and risk of harm when choosing between alternative treatment options. International guidelines for reporting medical research results are sufficiently specific when it comes to establishing health benefits. However, there is a lack of standards for reporting on ruling out risks. We argue that transparency is needed, as in the case (...)

    Science and proven experience : a Swedish variety of evidence-based medicine?Johannes Persson, Niklas Vareman, Annika Wallin, Lena Wahlberg & Nils-Eric Sahlin - unknown
    A key question for evidence-based medicine is how best to model the way in which EBM should “[integrate] individual clinical expertise and the best external evidence”. We argue that the formulations and models available in the literature today are modest variations on a common theme and face very similar problems. For example, both the early and updated models of evidence-based clinical decisions presented in Haynes, Devereaux and Guyatt assume that EBM consists of, among other things, evidence from clinical research and (...)

    How do we and how should we deal with uncertainty in Endodontics?Maria Pigg, Joséphine Brodén, Helena Fransson & Niklas Vareman - forthcoming - International Endodontic Journal 55 (4):282-289.
    In many clinical cases a dentist may feel certain when for example diagnosing, deciding on treatment, or assessing the prognosis - in other cases many dentists may feel a degree of doubt or uncertainty. This paper aims to explore the philosophical concept of uncertainty and its different dimensions, using the condition "persistent apical periodontitis associated with a previously root filled tooth" as an example. Acknowledging that uncertainty exists in any clinical situation can be perceived as uncomfortable, as some might regard (...)

    Epistemic Risk : Issues on the normative basis of risk analysis.Niklas Vareman - 2014 - Dissertation, Lund University
    The articles included in this thesis centre on what can be called the normative basis of risk analysis. Since risk analyses are decision procedures, they should adhere to norms of rational decision-making, and this they do. Most risk analysis schemes are built on a notion of the decision theoretic maxim that the goal of every decision is to maximize expected utility. However, for some thirty years now this maxim has been called into question. The idea is not that it is (...)

    Norms and descriptions.Niklas Vareman - 2008 - Decision Analysis 5 (2):57-111.
    The problem addressed in this text is the problem of identifying conditions according to which it is possible to distinguish between a descriptive theory and a normative theory. What makes a descriptive theory descriptive and a normative theory normative? Focus is on subjective expected utility theories where it seems open to debate whether the appropriate use is normative or descriptive. My discussion, which takes arguments by Isaac Levi and Hugh Mellor as a point of departure, is mostly negative, showing that (...)
