Distinguish evidence from an assumption.
The idea
Use I know for verified information, I assume for an inference and might for a possibility. As far as I know limits a claim to your current knowledge.
Examples
- I know the shop is closed today.
- I assume the delivery will arrive tomorrow.
- The lights are off, but I cannot be sure anyone has left.
- As far as I know, the meeting starts at noon.
- It might rain, although the forecast is not clear.
- I will check the timetable before we decide.

Watch out
Do not present a guess as a certainty: an unconfirmed delivery is not something you know.
