There are several types of reasoning you can employ to address your question:

Inductive - creation of an explanation (general conclusion) from specific instances known to be true. This approach follows Newton's Principle: Whatever is true of everything we've seen is true of everything in the universe (Pedro Domingos).

Deductive - creation of an explanation (specific conclusion) from general principles known to be true. As Sherlock Holmes advises: When you have eliminated the impossible, whatever remains, however improbable, must be the truth.

Dialectic - creation of an explanation by unifying initially opposing theories (Richard Nisbett). The Socratic Method, which examines hypotheses through discussion, is an example of dialectic reasoning.

Discriminate between the causal and the coincidental. A powerful explanation of the facts must be hard to vary (David Deutsch).

a law will be the more precious the more general it is.
