Airports have many checks, but typically none in the luggage claim area. Why does typically nobody check whether one picked up one's own luggage (and not somebody else's or forgetting one's luggage) at the airport's luggage claim area? I'm curious if the reason is simply that there's no need for that, and/or is motivated by the desire to save airport's money or passenger's time, or some other reason.
Close voters: this isn't at all opinion-based, airport authorities most likely have made some statements about and/or released statistics, and there are plenty of research papers on airports e.g. https://doi.org/10.1016/j.jairtraman.2004.09.004
