Conclusions: Some suggestions for evaluators' daily work in a post-truth world

The evaluation aims to improve public interventions (policies and programs) and ultimately contribute to social betterment and justice (Chelimsky, 2006; Henry & Mark, 2003). Daily practice typically involves evaluators assisting policy-makers and policy-takers in finding a better match between policy problems and available policy solutions. Previous volumes of The Comparative Policy Evaluation series have comprehensively discussed the challenges associated with the evaluation mission and its practices (see, for instance: Leeuw et al., 1994; Rieper et al., 2012; Palenberg & Paulson, 2020). However, post-truth, which in short denies evidence and facts, provides a new context in which evaluators work, making the evaluation mission even more challenging.
