Richard Feynman, God of Perfect Analogies, explains why it's not a failure or a scandal when scientists adapt and change their understanding of the world. This is a really important point, applicable in a lot of public debates over science, especially those focused on evolution and climate change. Science isn't about writing things on tablets of stone. It's about taking a theory and constantly digging deeper into it—adding layers of nuance, finding stuff that doesn't make sense, and using both to build a more complete picture. Even if the big idea is right, the details will change. That's how science is supposed to work.
