Is it OK to Change Your Mind?
Changing your mind while conducting library research is likely a positive thing. Here's why:
As you research your topic idea, if you find your understanding deepens or you learn something new that changes your perspective, this is a signal that you're developing a more nuanced (better) paper or project. Since library search algorithms do not (currently) mine your personal data to present you with information designed to influence you (which is the case in too many online spaces), if you are using Library Search, new ideas are more likely to come as a consequence of your research question and not commercial influence.
