The user "Picabu" Tech.spiritus created a test for trusting. To go through it, you need to lower the 10-ruble coin into the monitor-after that the device will “measure” the level of gullibility and give out the result.
“Dedicated to thousands of pseudo-diagnostic devices, from e-meter of scentologists to any auramamer,” the author wrote on his blog.
The idea of the device Tech.spiritus borrowed from the caricature (but there they ask for a whole dollar for the test!).
