In addition to asking other critical questions when trying to judge if a study if meaningful or reliable, one of the most important things to know is how the study was controlled. In general, you should trust only controlled randomized, and double-blind studies. These three research-nerd words that simply mean that the subjects were put into groups in a random fashion that wouldn't skew the results, and researchers themselves were unaware of which subjects were actually being tested, and which were in the "control" group (in a drug study, they would be given a placebo or another treatment).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
