Components of a Scientific Theory

Refutability

A scientific theory must have the possibility to be refuted.

Evidence that do not refute a theory are the evidence that support it.

Irrefutable Theories:

Alfred Adler's individual psychology.

Freud's psycho-analysis theory.

Karl Marx's thoery of history.

Falsification

A scientific theory must have the possibilty to be falsified.

Subtopic

Subtopic

It should forbid certatin things for happening, the more it forbids the better.

Evidence for a theory do not support it, they present a serious challenge that has failed to falsify the theory.

Testability

It should be testable, every test is an attempt to falsify it. So the more the theory can be tested the greater risks it takes.
