She asked me to help her anticipate the main objections raised against doing impact evaluations—evaluations that measure how much of an outcome can be attributed to a specific intervention–and to suggest possible responses. I realized that five particular objections come up over and over again.
Objection #1: “We already spend a lot on evaluation”
Objection #2: “Impact evaluation methods can’t be applied in our field”
Objection #3: “Impact evaluations cost too much”
Objection #4: “We know that our programs work so it would be a waste of money”
Objection #5: “Impact evaluations don’t affect policy decisions”
