How common is it to mention that a discovery was made by accident and if it is acceptable to say that in a paper?
We often hear historical accounts on how discoveries were made by accident, however, I never saw it mentioned in a paper. I wonder if here would be a good place to ask for examples.
I am asking that because I recently made a discovery and the specific conditions I used were simply by mistake. These conditions were not used before and it was not my intent to use them, I just used the buffer of a different experiment.
Usually, there is an explanation of why a specific condition was chosen, but if there is no reason beforehand, is it better to come up with an explanation or to state it was by trial?
