Good question! I don't believe that we are...his definition is too strict. In my opinion, Popper missed the point when scientist use the term "falsification". We falsify in order to make mistakes so that we can recognize them, eliminate them, and move on so that we can get closer to the truth.
I'm starting to like you Clive.
