What should you do if you find a lost item that's not yours?

We've all been in this situation. You accidentally leave your phone (or any other important item you would be saddened if you lost) in an obscure location you can't remember. When you finally remember where you left it, you desperately return to the location only to find that the phone isn't there! You are forced to assume that that wasn't where you had left it in the first place, and you proceed to search aimlessly. Sadly, here's what actually happened: somebody found your phone, realized that someone else had lost it, picked it up and tried to find its owner. Although their cause may have been noble, it was clearly in no way beneficial to you.

Here's a funky method for dealing with finding items that other people lost:

Don't do anything.

Think about the thoughts that go through your mind immediately when you lose something: where was the last place I left it? To find a lost object, most people will backtrack their day, highlighting possible areas where the item could have been dropped and proceeding to search those areas. If a person removes the item from the area, there is no feasible way for the person to find their missing item!

If you are on a college campus and you see a shiny new iPhone left on a desk, don't touch it! College schedules are usually routine, so it is easy for people to backtrack their days and highlight areas where they could have left it. True, some people might decide to steal it, but the more important a lost object is, the more urgent the realization is to recover the item. So if a shiny new iPhone is left on a desk, it will probably be found by its owner sooner than you would expect if you just don't do anything.
