Can we first claim and then find evidence when we write a literature review?
I have a question regarding a researcher’s practice in writing. Let me give you some background about this issue. Here’s what this researcher does when writing introductions and literature reviews. He makes certain speculations first and then proceeds to making claims based on those initial speculations. It is worth noting that the claims he makes are sometimes too specific. Following that, he starts looking for evidence to support his claims. I have tried many times to convince him and have told him that this is not the right way to write a research paper. It’s more like writing a composition rather than an academic piece of writing which aims at making contributions to the world of education. Here’s part of what he recently wrote in an email in response to me: “I disagree that making claims and looking for evidence supporting them is "not academic". Maybe I am wrong but this approach is less exploratory than the method you have in mind. For example, [Michael] Kane's framework is based on this method: Claim --> evidence. Kane specifically stresses the importance of opinions/judgments etc. I personally do not prefer to tie my mind merely to the literature --I do not find it much academic in the sense it does not engage me in critical thinking. My method is: "The theory I wish to develop does not exist out there; I develop and support it"” I would like to have your opinion regarding this issue. Is what the researcher claims really right? If not, can you introduce some published sources which have attacked this practice?
This is a very interesting question. Your question seems to mix up two components of a research paper---(1) the theory or hypothesis, which is what the authors set out to validate through the study, and (2) the literature review, which is where the authors use existing literature to build a case for their theory.
To quote your researcher friend: "The theory I wish to develop does not exist out there; I develop and support it." This would not constitute the literature review but the actual study itself or the research question.
Coming to the literature review, it cannot be entirely based on speculation, although it's okay for the authors to take a guess at some specific points and then look for references to support them. Ideally much of the literature review should be undertaken before beginning the study. Authors should read through whole papers and related papers cited within them to form a view of the established trends of thought in the field. It would also be useful at this stage itself to highlight or mark out statements that they think might be useful references for their manuscript. They should then formulate their research question and study design so as to fill a gap in the existing literature.
At the manuscript writing stage, the authors should already have a good grasp of the related literature that exists. They then need to put this literature into perspective to support their research question and findings. At this stage, they may make specific statements and then look for references to support them, in the manner you have mentioned. However, since by this time, they should already be familiar with the literature, the statements they make in their manuscript are not likely to be purely speculative. It is also important that the authors cite statements from previous studies with due consideration to the context in which these statements were made in the original studies.
I hope this answers your question!
