I wonder if location prompts would be more effective if, instead of asking "Allow 'Example App' to access your location while you are using the app?", they explicitly state "'Example App' would like to know precisely where you are. Would you like to share your exact location?". I feel like those adjectives, "precisely" and "exact", would go a long way toward encouraging people to put more thought into the decision. Similar wording could be used for other permissions, maybe in conjunction with a one-or-two-second timer on the buttons.
