The word creativity has many different meanings, depending on who is speaking. For "packers" it is an umbrella term they use when they are unable to grasp how, say, Rich Hickey came out with Clojure all alone (a few fundamental ideas put together plus ripping out CL) or how Igor Sysoev wrote nginx (after studying Apache's internals and coming up with a better model) or what is so special about Arc language. For other people it is just the set of habits of thinking which is natural to them, so they literally cannot see what is that people are talking about. There are the majority, who think that creativity is something which is related to [visual] arts, some kind of mindset. They use this word to justify an inability of a kid to sit down and do the homework as being a creative nature. No wonder packer managers want none of these.) There is no "creativity" which can be boosted aside from habitual analytical thinking and hard work. Insights could appear only after extensive training of ones mental maps.
