Information hazard
An information hazard, or infohazard, is "a risk that arises from the dissemination of (true) information that may cause harm or enable some agent to cause harm", as defined by philosopher Nick Bostrom in 2011, or contained in information sensitivity. It is an idea that contradicts the idea of Freedom of information as it states that some types of information is too dangerous for every single person to have access to, as they could either be harmed by it or harm others. This is sometimes the reason information being classified of importance to information sensitivity. One example would be instructions for creating a thermonuclear weapon as following the instructions could cause massive amounts of harm to others, and limiting or at least controlling who has access to that information would be a way to avoid that harm.
