My last post used a tag that read “Trickle Down Hypothesis“. I wrote it this way because conservatives who adhere to trickle down don’t understand the difference between the two, or if they do, are purposely misusing the word “theory” to help their cause.
Hypothesis: A suggested explanation for an observable phenomenon or prediction of a possible causal correlation among multiple phenomena.
Based on: Suggestion, possibility, projection or prediction, but the result is uncertain.
Theory: In science, a theory is a well-substantiated, unifying explanation for a set of verified, proven hypotheses.
Based on: Evidence, verification, repeated testing, wide scientific consensus.
Clearly, Trickle Down has never been verified by a wide scientific consensus, therefore it is not a provable Theory.
