Most forged art is not very good or well-executed. It succeeds not because of the quality, but because of an invented provenance that turns off the critical mindset of the viewer:
A number of the forgers — more than half — if you just look at their forgeries in a vacuum, it’s surprising that they fooled anyone. Han van Meegeren’s Vermeers don’t look anything like Vermeers, but they managed to fool people. It is always the accompanying story, the invented provenance — which is essentially a confidence trick that manages to pass off the object — that really tricks the buyer. On further inspection, it’s always a surprise that the work itself could fool people. The way they do it is with a very compelling provenance.
Obvious connections here to assessing the quality of arguments or facts.
Also a connection to the fact that most hacks are the result of Social Engineering
