I think talking to your professor about it is a good idea. Personal opinion is human nature and even the best researchers have one! The key is to remain unbiased when viewing the results of the research and not letting your personal opinion affect the information that you share, particularly if that information doesn't align with your personal beliefs on the topic. Your professor will likely have some great insights to share about how she remains unbiased during research.

Best of luck with your project!
