Features of Science
Replicability
-
For a scientific theory to be trusted the findings must be shown to be repeatable across a number of different contexts and circumstances

Also used to assess the validity of a finding - allows us to see the extent to which the findings can be generalised
Important for psychologists to report their investigations with as much precision and rigour as possible - other researchers can seek to verify their work and verify the findings they have established

Falsifability
-
Genuine scientific theories should hold themselves up for hypothesis testing and the possibility of being proven false
Popper believed that even when a scientific principle had been successfully and repeatedly tested it wasn't necessarily true
Theories that survive most attempts to falsify them become the strongest as they have not been proved false - this is why a alternative hypothesis must be accompanied by a null hypothesis
