The primary difference between hard analytical science and soft economic science is that economics has too many variables to isolate and test effectively, and its works on too large of a scale for any type of testing to be practical. Alas, it is why Economics is often called "The Dismal Science" For example; in physics, if you wanted to test, say, whether or not general relativity is correct, you can go outside, wait for an eclipse, and observe the appearance of stars. If the star's position changed, then general relativity is correct.
If they don't then general relativity is not. However, in economics, if you wanted to test, say, whether or not rent control is an effective policy for a city to pursue; one could point to the failures of rent control in Manhattan after World War II, or their modest success in Paris in 2004. Markets are such complex things that we wouldn't be able to exactly pin down what exactly made rent control fail in Manhattan or if it even failed at all. There are ... more.
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.
