Error Formula Features:

1. Claims to be scientific, but vague and lacks specific weights and measures.

2. It is not possible to use operational definitions (e.g., generic variables, belongings, or objects that can also be verified by outsiders).

4. Use ambiguous language and use a lot of technical jargon to make the article look scientific.

5. Lack of boundary conditions: rigorous scientific theories are clearly defined in terms of scope, clearly indicating when and where the phenomenon is applicable and when and where it is not applicable.
