24	Terminology key
25
26	Terms used across GiveWell's CEAs
27	Internal validity	Describes an adjustment we make to the treatment effect of an intervention to account for the possibility that the treatment effects found in studies may not represent the true effect the intervention had on the populations studied.
28	External validity	Describes an adjustment we make to the treatment effect of an intervention to account for differences in the program implementation or populations treated in studies from the program implementation or populations treated by grantee programs.
29	Leverage	Describes a situation where a grantee's spending on a program causes other organizations or governments to contribute more to the program than they otherwise would have. In most cases, accounting for leverage increases cost-effectiveness
30	Funging	Describes a situation where a grantee's spending on a program causes other organizations or governments to contribute less to the program than they otherwise would have. In most cases, accounting for funging decreases cost-effectiveness.
31	Counterfactual	In most cases, describes the state of the world that would exist if we did not provide funding to a grantee for a program. When discussing the "counterfactual value of other actors' spending," we are referring to how much benefit another organization's or government's spending would generate if it were spent on something other than the grantee program.
32	Moral weights	To compare cost-effectiveness across different programs, we use ‘moral weights’ to quantify the benefits of different program impacts (e.g. increased income vs reduced deaths). We benchmark the value of each benefit to a value of 1, which we define as the value of doubling someone’s consumption for one year.
33	Philanthropic actors	Non-governmental organizations (NGOs) providing funding to philanthropic programs.
