Part of our goal as a research organization is to develop methods for evaluating interventions and charities. The methods we’ve developed are tools that can be applied by ACE and by others to understand a variety of situations, and while they often draw from other evaluative practices, ACE uses them in specific and sometimes unique ways. These pages offer details on certain aspects of our evaluative process.
To communicate the process by which we believe change occurs, we use theory of change diagrams. It is important to note that these diagrams are not necessarily complete representations of real-world mechanisms of change. Rather, they are simplified models that ACE uses to represent our beliefs about mechanisms of change.
This menu of outcomes has been developed to inform ACE's charity evaluations, intervention evaluation process, and to support advocates in better defining and evaluating their advocacy outcomes.
One way that we evaluate interventions or charities quantitatively is by calculating a cost-effectiveness estimate (CEE) in terms of “lives spared per dollar” or “years of suffering averted per dollar.” On this page, we describe our process for developing CEEs and the role that they play in our intervention reports and charity evaluations.
We use subjective confidence intervals (SCIs) in our work to identify the best ways to help animals. Here we explain what our SCIs are and how we use them, and provide some simple and detailed examples to help clarify possible points of confusion.
