Limited Scope

Description: The theory doesn't explain anything other than the phenomenon it explains, and at best, is likely to be incomplete.  This is often done by just redefining a term or phrase rather than explaining it.

Example #1:

My car broke down because it is no longer working.

Explanation: “It isn’t working” is just another way of saying “broke down”, and fails to explain why it broke down.

Example #2:

People often make hasty decisions because they don’t take enough time to consider their choices.

Explanation: Not taking enough time to consider choices is precisely what a hasty decision is.  Again, no explanation is offered, just a definition in place of an explanation.

Exception: If “because” is replaced with a phrase like, “in other words”, then it is a deliberate clarification and not a fallacy.
