I was thinking to software readability.
First of all I would like to explain what is an evidence based approach and how it's related to software engineering.
Disciplines like medicine use this kind of approach a lot. Every opinion has to be proved through a scientific test made in double blind. You can see thousand of examples making a search on Google Scholar. Example: link
This kind of methodology assure that nothing is lead to the personal opinion of the writer. Psychology is another discipline which passed from intuitions (see psychanalisis) to rigorous scientific approach. Not always a method is better than the other but scientific approach to software coding is almost unexistent nowaday.
My actual question is if someone knows about the usage of Functional magnetic resonance imaging (fMRI) to experimentally investigate the readability of some piece of code refactoring.
I understand the question may look weird. But the actual medicine is able to "see" the effort made by the brain of a developer to understand some lines of code. So it's possible to empirically measure the readability of a source code.
One of the purpose of the question would also be to make software developer focus on the possibility (and need?) to go over the opinion based approach to a evidence based software engineering
Would my question be out of scope here?
<whatever>
" doesn't sound okay in the light of that guidance
