The problem, imho, is that different types of science have different levels of “testability”. For example, physics and chemistry are extremely testable. Any hypothesis or result can be immediately put to test by many labs and see if the results are reproducible. Medical science less so. Much of our advances in medical science comes from statistical analysis of long term results (typically against a placebo), not from “knowing” how the body works in full. Over time we’re getting better at understanding the body and develop better technology and drugs. We still have to rely on lengthy processes to prove something is safe for the market. So it’s still testable but not as directly or quickly.
Then we have other sciences, like “climate” and “social” sciences. These “sciences” are not testable. We do not have a spare earth where we can test changing a variable to see the impact and effect. Similarly, we can’t change everyone’s opinion on social issues to prove or disprove their validity, they’re really just ideas.
I’m unaware of any “testability index” for the various sciences, showing how much more testable one type of science is vs another. For climate science, you’re reduced to “computer models” because you can’t change variables for experimentation on a global scale. Nothing more than garbage in garbage out. When the models don’t match reality you don’t have “science”.
Excellent post.
The whole premise of testability and falsifiability has been thrown out the window by modern science. There are many areas where scientists should admit they can make no conclusions, but so many have an agenda now that they have lost all sense of humility.
