The writing on the sign says pull but the handle, without so many words, says push. So either this is a door that is meant to be pulled but someone forgot to make it pull-able, or else it is a door that is meant to be pushed but was accidentally signed as a pull.
Unfortunately for us, the only way to find out is to try both pushing and pulling it and see what works. And here we find the limitations of our medium. We can only observe interesting or amusing things about reality; we cannot test out our theories and interpretations. Guess we’ll have to move on.
