Specifically, what do we mean when we say that a scientific hypothesis must be testable?

Answer 1

#"All cows eat grass."#

This is a testable hypothesis since we can find a cow that did not consume grass in order to refute it. Since a newborn calf consumes its mother's milk, we can ignore the general hypothesis in this case.

The hypothesis that "white wine is better than red wine" is untestable. Is there any experiment that could be done to test this hypothesis? At most, we could compare one bottle of red wine to one bottle of white wine and get different results.

Which of the following is the hypothesis' testable proposition?

#"Pepsi is better than coke"# (And in fact, Chinotto is better than both of them!)

#"Pepsi is more carbonated than coke"#.

When we say that a scientific hypothesis must be testable, we mean that it must be formulated in a way that allows for empirical testing and validation through observation and experimentation.
