WEBINAR – Evidential Pluralism

Integrating evidence and overcoming the limitations of existing evaluation guidance

Building on the previous webinar that we presented last year, this session delves deeper into Evidential Pluralism…


Many interventions take place under conditions of extreme complexity, and require the integration of a broad evidence base to accurately assess their effectiveness.

Existing guidance typically takes experimental evidence, often drawn from RCTs, to be of intrinsically higher quality than other kinds of evidence and can exclude these other kinds of evidence from consideration. However, it is hard to produce high quality, blinded RCTs for many non-pharmaceutical interventions. For social policy evaluation, a new methodology that can handle a wider range of evidence is required.

In this presentation we will introduce such a methodology, based on Evidential Pluralism, a philosophical theory of causal enquiry. Evidential Pluralism offers a framework for understanding how to integrate different kinds of evidence when evaluating whether an intervention works. It yields evaluations informed by all relevant evidence, not just a small subset of experimental studies.

We will discuss a number of case studies and practical examples, showing the benefits of integrating different kinds of evidence when evaluating policy interventions.
