Understanding the process of how and why someone changes their mind seems vital to me. As I’ve noted before, understanding this is of fundamental importance to the process of public sector change.
Here’s a nice article on whether economics can change people’s minds (via Marginal Revolution), including examples of where it has done exactly that.
Altogether, there are many examples of economists who change their minds, even when doing so involves repudiating their own previous research and policy positions. Maybe these economists are special and possess an inhuman lack of bias. But I doubt that.
Feel free to share examples of where you’ve changed your own mind, particularly when it comes to public service reform.
