There is a chance of the “cry wolf effect” taking its toll on people who hear the alarm too much but that’s primarily handled by just informing the public that it is indeed a test and not spamming it every day. The FCC has to make it a compliance rule for networks to keep their special alert broadcast tools maintained otherwise they would have no real incentive to do so. If they don’t then if a real emergency happens and they find that their equipment has not been maintained through routine testing then people’s lives could be in real serious danger.
