I have limited resources for investigating robberies. I need to allocate these resources efficiently. 5x more robberies are reported in zone A than zone B. Why would I allocate an equal amount of resources to each zone? I have limited resources for investigating fraud. I need to allocate those resources efficiently. If profile A is more likely to commit fraud than profile B, why would I allocate an equal amount of resources for investigating fraud between them? I'm going on a hunting trip and have limited time and resources for hunting. I need to plan my trip accordingly. If deer are more abundant for hunting in Colorado, why would I go looking for them in the Sahara? Am I wrong to look for deer in Colorado rather than the Sahara? Am I biased for investigating fraud where it's more likely to occur? Am I evil for investigating robberies where they're reported? I have little time and resources on this planet and want to allocate my time and resources as efficiently as I can in order to do the most Good. Why would I allocate my time and resources inefficiently?
