What if I conduct a study and suggest a hypothesis to test but later find out that this hypothesis was already tested before in a different industry/country. Can I still continue? In other words, is there such a thing as plagiarism in stating the same hypotheses?
I find it a burden to go and check the web for every hypothesis I write to see if someone else tested it before. Even though I am sure there are some common hypotheses and studies (like: customer loyalty leads to customer retention, albeit in different industries and/or countries) but I still have doubts.
