Well, for a start, I got a meme detector and learned how to operate it. The modern ones have a battery pack that you wear and an electronic probe on the end of a frame that you hold up close to the screen. The meme detector has a small suction motor that draws the air in from around a Facebook posting and sends signals to its computer for analysis. Once the signal is processed the meme detector notifies you via headphones whether the sample is bullshit or not.
The detector is connected via a WiFi transmitter to the snopes.com website and can access all their recent data. If something has been rehashed and presented to the gullible public as a true image or real thing that happened…but is not…this information is sent back to the meme detector and I can be warned. Usually it is done by a discrete red light on the side of the casing, though the new model Fraudbuster 800 will play the sound of a cynical raspberry into the headphones.
None of this will stop well-meaning people from lighting upon something that triggers them off, being taken in, and then re-broadcasting the original meme. But it may prevent me from being taken in far enough to react to the thing, or to cast it further over the heads of the populace. To paraphrase Harry Truman, ” The fuck stops here. “.
