I’m trying to get a job as a reporter but for the like of me Icant raise my knowledge(iq) Ive bought about every single but that sounds good for it ut it just wont go up!!
Knowledge(IQ) is more of a “current events” thing, like a less culturey version of Knowledge(culture). The quickest solution is to watch the international news, and pick up a news magazine whenever you go shopping, though both of these will affect your happiness.
If I’m not mistaken, a broadsheet subscription should also help, as will certain websites and possibly the encyclopedia, but I haven’t had much success with any of those.

From memory some of these have degrading IQ_Knowledge (e.g. magazines), but for the most part they’re permanent.
Good luck with your quest for knowledge and/or power
