Consider the following situation. Mohammed is a third year undergraduate student studying epidemiology. His professor is highly regarded in the field and Mohammed is very excited to study under him. However, while trying to replicate one of his professor’s experiments, Mohammed notices that his professor made a small error when calculating the data for the original experiment. When Mohammed fixes the error, it changes the results so much that the conclusion isn’t correct any more. Mohammed checks the original and his own multiple times but he still gets the same result. Mohammed is very concerned because the paper with the published results of the experiments his professor did has been referenced many times. Mohammed decides to approach his professor with the mistake and his calculations. However, his professor tells him not to worry about it and that “is just how science is”. His professor does nothing. What should Mohammed do now?
