s1=c1 is an idea/concept/thought that is potentially harmful to c2 under conditions c3.
The being put in jeopardy by the concept is not necessarily the thinker of the concept. For example, the concept of a certain type of terrorist act is not (only) dangerous to the would-be terrorist. 'Thought hazard' has a broader meaning than 'informational hazard' and 'knowledge hazard' (capselju'o, junckape, capfatci or facyckape – closely related words), which have to do with dangerous ideas that are true. [See Bostrom (2011).] Synonymous with sibyckape, which some may prefer.
