Difference between Perception and Investigation skill

Of all the skills, Perception and Investigation seem to have the subtlest distinction. Is there a rule of thumb when to use each?

Investigation use

Thank you, O Wise Sage. I just found this on Reddit, and it really helped me, so sharing here for anyone else that’s curious:

Perception – You scan the room and notice a section of wall is discolored, appearing somewhat newer than the rest of the wall. You realize it may be a secret passage.

Investigation – You probe the wall, knocking on it, pushing at various stones trying to figure out how to open the passage.

Torture is evil

DM, just say yes
