An Information Hazard is some information which could harm people if known. It is tricky to determine policies on information hazards. Some information might genuinely be dangerous, but excessive controls on information has its own perils.
This tag is for discussing the phenomenon of Information Hazards and what to do with them. Not for actual Information Hazards themselves.
An example might be a formula for easily creating cold fusion in your garage which would be very dangerous. Alternatively it might be an idea which causes great mental harm to people.
