Quote From Tudor_Queen:
Just an example of where you can cite scientific papers without having read them. It isn't just black and white - there are several grey areas.
You are scraping the barrel here with this example :-) Knowledge of the statistical method and interpretation of the result is the crucial thing in your example. How the software efficiently makes the calculations for specific hardware platforms is barely relevant.
Do you have any good examples where knowledge contained within a paper is crucial to understanding the science?
