Science often does not demand arbitration or selection criteria between models which make the same testable predictions.

More to the point, every decent evolutionary explanation has testable predictions about the design of the trait.

They then explore the consequences of these ideas and work toward making testable predictions.

Further to this, in 1998, Hameroff made 20 testable predictions related to his proposal.

And some opponents claim that the theory has never made a testable prediction.

One must always add auxiliary hypotheses in order to make testable predictions.

Nevertheless, researchers' idea of a good hypothesis is one that generates interesting and testable predictions.

Hypothesis: A testable prediction which designates the relationship between two or more variables.

At the moment such wave analysis represents the best hope to obtain physically testable predictions form the model.

The ultimate measure of success is however the ability to make testable predictions.
