Theory Must Install Constraints

Chapter 2, Section 2: Theory Must Install Constraints

Don't forget, a theory with explanation power must be refutable, or else it'd be of no use at all. What's equally important, to make predictions for a behavior, science must install constrains. Without constraints, the behavior can modify from time to time, like unsteady wind, and that makes no prediction wrong and the theory irrefutable.

A behavior must have constraints like under which circumstance it goes left instead of right; only in this way can the behavior be explained. Of course, when predicted to go left, the behavior may go right. So a theory that explains is possible to be refuted, but hasn't yet been. This has been explained in Chapter 1. More constraints usually means more accurate predictions, but that widens the chance a theory may get refuted as well. So science is an adventure game. The more constraints a theory has over a behavior, the better, but it shall never step into the realm of refutation. Only virtuosos of science can make assumptions boldly but weigh them cautiously, and by that way push the constraints to the safety limit that the theory won't get refuted.
