Controlling Subjectivity in Risk Decision-Making: The Benefits of Multicriteria Decision Analysis

Abstract

This paper begins with a discussion of subjectivity in risk assessment and risk management and how that is partly a reflection of subjectivity more generally in the sciences. It finishes the first part suggesting that we are taught a simplistic control of subjectivity and that we have in too many instances thought that statistical tests, etc., are automatic controls for subjectivity. In Part 2, I discuss how subjectivity is a necessary part of decision-making under uncertainty and quality risk management. Experts are consulted to provide estimates of probabilities for parameters, scenarios and the likely consequences. I end with an introduction to multicriteria decision analysis as an approach for structuring complex decisions under uncertainty, both for our daily lives and for team decision making in our organisations.
