Avoiding such false messages on the human layer is all about interface design and we know how to do that in principle. The problem is just that it isn't done always when it is needed. In case of the Hawaii missle alert there are multiple sources describing the UI as being two similar looking buttons right next to each other: https://www.theguardian.com/technology/2018/jan/15/hawaii-missile-false-alarm-design-user-interface https://www.theguardian.com/technology/2018/jan/15/hawaii-mi... Just make the actual missle alert button big and red and have users confirm a prompt after clicking. In Reagans case it is also about the "interface". If footage that leaved the set is not checked, because there is no delay, well then unchecked footage goes out.
