Expert writing Tips
Best practice
Place the phrase before a 'that' clause to clarify the content of the assumption, such as in the example: 'They "rightfully assumed" that the meeting was canceled.'
Common error
Do not confuse the epistemic use of the phrase (meaning to believe something is true) with the performative use of 'assume' (meaning to take on a role or power). While one can "rightfully assumed" a position of authority, this refers to a physical or legal action rather than a mental conclusion. Ensure your context distinguishes between 'believing something rightfully' and 'taking something rightfully'.
