Both are required in conducting scientific research because innovation requires creativity to be possible, and creativity requires innovation to be useful.
Logical thinking is creative and should be a part of scientific research. Creativity helps one to come up with new ideas leading one to novel ways of thinking and advancement in research. It will help one to discover new things which will solve problems that have not yet had any solutions. Creative thinking or trying something novel will help a researcher to enjoy his/her work. Creativity may not always end up in something useful. But one must always bear in mind that in science getting things wrong is just as important as getting things right. One may perform hundreds of experiments trying to work out a novel idea but fails. This does not mean a “waste of time and resources” because these failed experiments will teach one about many things that will not work.
Innovation is as important as creativity because it involves intentional introduction and application of new and improved ways of doing things. Creativity may help in generating new ideas but not necessarily involve the implementation of those ideas. Innovation does! Innovation and creativity are both dependent on a process of allowing non-standard thinking or ideas to come up, with creativity being more experimental than innovation. Thus, to innovate, one must implement.
So, if one is serious about innovation, don’t waste time and potentially freeze those multitude of novel ideas. But instead focus on those ideas that may be truly useful for execution.
Thus, creativity and innovation, both are important in scientific research to discover new things that may ultimately benefit the society at large.
Replication of old research topics reported by other scholars, while useful , lacks both creativity and innovation. These factors are important if a researcher is thinking about the expansion of scientific borders.
Research means the use of existing knowledge in a new and creative way, therefore creativity and innovation are essencial in coducting scientific research. It is a continuous process where researchers carry on their researches from where others have stopped.
With all due respect Reza, I disagreee with your premise. I would say more, but am busy finishing off my book and think it better that you read the whole thing and perhaps then you will think otherwise. But it is a good question and in that sense to. be taken seriously. I mean the question of whether all old questions fall into the same category?
