Peer-review in biology-related fields doesn't bother too much about the details of your code. Only recently a few journals begin to ask guys to submit the source code if the manuscript is mainly about some new analysis methods. So it is more than likely even if you are reading submitted manuscript of a computer program, you won't read the source code with the paper. Another thing is that statistical analysis is kind of the missing piece in many researches training. It maybe not be "researchers cut corners", but they might not know some of the prerequirements for the analyses used. Even in this year, 2016 when I talked with a colleague in my institute I found out he didn't know a single assumption for t-test, who is a senior postdoc and used it everyday.
