To my father
That the very concept of objective truth is fading out of the world... frightens me much more than bombs.
George Orwell
A Quick Introduction:
The Subtle Ways Language Influences Thought
Oh hello! Mr. Rabbit here. Im pleased to meet you. You might be wondering how Ive reached this, ahem, honorable old age. Ill tell you: Careful listening is essential for a rabbitand today, sneaky language is more prevalent than ever. Its prevalent in everyday conversations, in newspapers and websites of record, in posts shared by influential people, and in speeches by eloquent intellectuals. It colors how we perceive our world. Youre holding a compendium of this kind of rhetoricnot only whats said out loud, but also whats left unsaid.
One reason rhetorical sleight of hand gets past us is that, when listening to someone speak, we tend to focus on whether we like that person rather than whether they are making any sense. Another reason is that our brains, by nature, process information differently based on context. Consider two well-known effects:
Priming. In a video that made the rounds online, a fun-loving group is sitting in a living room. Without showing any visuals, one of them asks anotheran English major, no lessto pronounce T-W-A, which she does phonetically. He asks her to pronounce T-W-I, which she does, the same way. Then onto T-W-O, at which point her increasingly peculiar attempts leave everyone in stitches. Other videos of that sort of gag are aplenty.
Whats interesting here is that our English major is using instincts that normally serve her well to try to answer a seemingly simple question. But, the information shes given at the start proves debilitating as she attempts to reason through what follows, all to great comedic effect. People are sensitive to what came just before!
Framing. In the classic example of framing, two groups of participants were asked to choose between two treatments for an imaginary disease that is about to kill 600 people:
Group 1 chose between A) a treatment that saves 200 people, and B) a treatment with a one-third chance of saving all 600 and a two-thirds chance of saving no one.
Group 2 chose between A) a treatment that causes 400 people to die, and B) a treatment with a two-thirds chance of causing all 600 to die and a one-third chance of causing no one to die.
