Science is a way to not fool ourselves.
In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
Interpretation
What this quote means
The quote emphasizes the importance of open-mindedness and the ability to change one's views based on new evidence, contrasting this with the rigidity often found in politics and religion.
Carl Sagan highlights the scientific method's unique capacity for self-correction, where scientists are willing to admit when they are wrong and alter their beliefs in light of new arguments or data. He suggests that while this change is more common in science, it is rare in the realms of politics and religion, which can be resistant to change despite evidence. This observation underscores the importance of humility and adaptability in the pursuit of truth, acknowledging that change can be difficult but is often essential for growth.
