Re: Conflicting information
@Charles 9 - I guess it depends on the situation - people are much more mentally resilient to "There's smoke coming from one of the toasters in the staff restaurant, please leave the building in an orderly manner - actually not really, it was just a test", than: "There's an incoming ICBM. These are the last few minutes of your life. You will never see your wife or your young children again, your last thoughts will be imagining your terrified children at school crying for you and you can do nothing, nothing to ease their fear. Ha! Psych! Not really!"
I recently saw a bit of video from the '70s or '80s showing an RAF early warning centre going through a training simulation of an attack being launched against the UK and it sent shivers down my spine.
