"Convictions are more dangerous foes of truth than lies"

This quote by Friedrich Nietzsche recommends that holding company beliefs and convictions can be more hazardous to the pursuit of reality than outright lies. This is since those who hold unfaltering to their convictions might be resistant to thinking about alternative point of views and evidence that might challenge or contradict their beliefs. On the other hand, those who want to accept the possibility of being wrong and reassessing their beliefs are most likely to come to the fact. Therefore, this quote can function as a reminder to always be unbiased and going to revise our beliefs because of new info.
