Although this opinion is contradictory in itself, fear-mongering is something that is not needed in a truly successful world. The idea of disinformation over individual information analysis will result in a close minded population that has been incapacitated mentally. Of course, should there be solid first source evidence to back up the 'fear-mongering', it would then be referred to as a secondary/tertiary source fact.
In conclusion, promote free thought and information accessibility for a successful, but not necessarily calm, world.
This should really be a given. Shouting 'fire' in a cinema will result in a jail term. Spreading rumours of terrorist attacks will result in a similar punishment.
'Splitting words so as to break (the force of) the laws; confounding names so as to change what had been definitely settled; practising corrupt ways so as to throw government into confusion: all guilty of these things were put to death. Using licentious music; strange garments; wonderful contrivances and extraordinary implements, thus raising doubts among the multitudes: all who used or formed such things were put to death. Those who were persistent in hypocritical conduct and disputatious in hypocritical speeches; who studied what was wrong, and went on to do so more and more, and whoever increasingly followed what was wrong so as to bewilder the multitudes: these were put to death. Those who gave false reports about (appearances of) spirits, about seasons and days, about consultings of the tortoise-shell and stalks, so as to perplex the multitudes: these were put to death. These four classes were taken off, and no defence listened to.' (Book of Rites 5.50) In short, anything aimed at bewildering the multitudes merited execution without defence. Fear-mongering is a type of bewildering the multitudes. Of course, these days, we don't have to kill people any more, but fear-mongering is still malicious, and those who commit this crime must be received judiciary sanctions.
Propaganda has been used since Sun Tzu published his Art of War a few thousand years ago and it still works as well today as it did back then. When politicians need to persuade people their best option is fear-mongering. Herman Goering (Nuremberg Trials) said, "Naturally, the common people don't want war, neither in Russia nor in England nor in America, nor for that matter in Germany. That is understood. But the people can always be brought to the bidding of the leaders. That is easy. All you have to do is tell them they are being attacked, and denounce the pacifists for lack of patriotism and exposing the country to danger. It works the same in every country."
