Answer:
It can be replicated and verified
Step-by-step explanation:
In order to be considerated scientific , an idea needs to go throught the scientific method, this implies that at the end stages of experimentation verification is needed.
A hypothesis will go several stages of experiments that make this statement verifable, often to be replicated in the physical or social world.
In this way it becomes part of a theory and then by being probably of happening again we conclude it is a valid source of knowledge.
Thereby, the ideas around superstition, religion or paranormal cannot be considerated scientific since the results cannot be replicated neither considerated.
