In the 1890s, Russian psychologist Ivan Pavlov was researching salivation in dogs in response to being fed. He discovered something remarkable about the human brain in the process.
He inserted a small test tube into the cheek of each dog to measure saliva when the dogs were fed (with a powder made from meat).
Pavlov predicted the dogs would salivate in response to the food placed in front of them, but he noticed that his dogs would begin to salivate whenever they heard the footsteps of his assistant who was bringing them the food.
Pavlov used a metronome in his breakthrough experiment. By itself, the metronome clicking did not make the dogs salivate.
Next, Pavlov began the conditioning procedure, whereby the clicking metronome was introduced just before he gave food to his dogs. After a number of repeats (trials) of this procedure he presented the metronome on its own.
As you might expect, the sound of the clicking metronome on its own now caused an increase in salivation.
Donald Trump gets Democrats hysterical with just about anything he tweets. It’s a classic Pavlovian response and Trump plays his opponents like a well-tuned fiddle. He doesn’t even have to say anything necessarily controversial. Whatever he tweets, his opponents see 1) racism, 2) fascism, 3) white supremacy, or 4) his enabling one or more of the previous. Trump tweets, Dems salivate. It’s classic. more
