"A man who has committed a mistake and doesn't correct it is committing another mistake." -- https://www.open.edu/openlearn/education/12-famous-confucius-quotes-on-education-and-learning
"Honesty really is the best policy if you discover an error in your own published work. It can be in your own best interest to self-report inadvertent errors to your publisher. Some errors can be handled with corrections rather than retractions. In the event that a work needs a complete retraction, self-reporting helps to indicate that an error was innocent, rather than a deliberate attempt at deception. Remember, failing to correct a known error can negatively impact all the other researchers who follow you, those that reference your research in their own work." -- C.Rose
In a 2018 qualitative study of retractions due to unintentional error, the authors stated “all interviewees reported how, contrary to their own expectations, the self-retraction had brought no damage to their reputation and in some cases had actually improved it.” -- Hosseini, M., Hilhorst, M., de Beaufort, I., & Fanelli, D. (2018). Doing the Right Thing: A Qualitative Investigation of Retractions Due to Unintentional Error. Science and Engineering Ethics, 24(1), 189–206. https://doi.org/10.1007/s11948-017-9894-2
