What is more important to you: a good education or a good healthcare system? Or perhaps employment or security is at the forefront of your mind at the moment. What about the environment or human rights? We all have different priorities in life and different sets of values with which we make judgements on things around us. Evaluations attempting to understand effects on people’s lives should at least attempt to try to understand the values of those people rather than imposing an external set of values. This week’s guest blog is from Laura Rodriguez Takeuchi, a researcher at the Overseas Development Institute. She introduces some practical ways that evaluators can begin to weigh people’s values as they relate to desired outcomes and distribution of benefits.
