I visited recently a course on "How to write a scientific paper" and there the course administrators suggested that we should avoid passive sentences. Why? It makes harder to understand your thoughts. My supervisor suggested keeping the passive tone in the methods because it emphasises the independence the work from you. If someone does the experiment accordingly then he or she will get the same results as you. It sounds ok till you see the sentences in your paper and then it makes them hard to understand. And you do not want your sentences hard to understand for your reviewer, do you?
What is the opinion of the ResearchGate community in this question? What are the experience of the fellow scientists, and editors?
