There are of course lots of examples of fine work going on around ACEs, but there are also aspects of the ACE movement that make me feel a little uncomfortable. I worry that what is clearly a well-intentioned desire to just do something might not do good and could cause harm. My concerns are absolutely not meant as a criticism of the motivation and altruism underlying the ACEs movement, but as a cautionary nudge to make sure that, in our enthusiasm to do good, we don’t run before we can walk.
