“I cannot help fearing that men may reach a point where they look on every new theory as a danger, every innovation as a toilsome trouble, every social advance as a first step toward revolution, and that they may absolutely refuse to move at all.” -Alexis de Tocqueville
You don’t need to be right to be a scientist, and your theory doesn’t need to be correct to be a scientific theory. While there is a big difference between the way we colloquially use the word theory (to mean “idea”) and the way scientists use it (to mean “testable idea”), there are actually three different stages that scientific ideas progress through.
One is to simply be an idea, which we normally think of as a hypothesis in the scientific process. The second one, which is more advanced, is to become a scientific framework, where the details and predictions are teased out, with the hopes that it goes from being testable in principle to being testable in practice, through observations, experiments and measurements. The highest level, though, is when a scientific theory becomes validated and accepted. Still, plenty of bad, incorrect ideas are scientific, too; we just need to have the courage to call them what they are: demonstrably wrong.
