These sorts of puzzles aren't used by researchers though, so I'm not sure I follow the rest. They almost always seemed to be used by people trained in logical thinking to consider problems in different ways. They only seem get to the larger public when someone shares one on social media and people with no background in logic complain that they are poorly written or have no answer, since they don't realize that these sorts of puzzles presuppose some background in logic and familiarity with the setup.
