Introduction: Questions rather than alternative facts

Evaluation in the Post-Truth World explores the relationship between the nature of evaluative knowledge, the increasing demand in decision-making for evaluation and other forms of research evidence, and the post-truth phenomena of antiscience sentiments combined with illiberal tendencies of the present day. Rather than offer a checklist on how to deal with post-truth, the experts found herein wish to raise awareness and reflection throughout policy circles on the factors that influence our assessment and policy-related work in such a challenging environment. Journeying alongside the editor and contributors, readers benefit from three guiding questions to help identify specific challenges but tools to deal with such challenges: How are policy problems conceptualized in the current political climate? What is the relationship between expertise and decision-making in today’s political circumstances? How complex has evaluation become as a social practice? Evaluation in the Post-Truth World will benefit evaluation practitioners at the program and project levels, as well as policy analysts and scholars interested in applications of evaluation in the public policy domain.
