Speaking of Reversals
“The BTU units meant nothing to me until I saw how much air- conditioning units vary. Joint evaluation was essential.” “You say this was an outstanding speech because you compared it to her other speeches. Compared to others, she was still inferior.” “It is often the case that when you broaden the frame, you reach more reasonable decisions.” “When you see cases in isolation, you are likely to be guided by an emotional reaction of System 1.” Frames and Reality Italy and France competed in the 2006 final of the World Cup. The next two sentences both describe the outcome: “Italy won.” “France lost.” Do those statements have the same meaning? The answer depends entirely on what you mean by meaning. For the purpose of logical reasoning, the two descriptions of the outcome of the match are interchangeable because they designate the same state of the world. As philosophers say, their truth conditions are identical: if one of these sentences is true, then the other is true as well. This is how Econs understand things. Their beliefs and preferences are reality-bound. In particular, the objects of their choices are states of the world, which are not affected by the words chosen to describe them. There is another sense of meaning, in which “Italy won” and “France lost” do not have the same meaning at all. In this sense, the meaning of a sentence is what happens in your associative machinery while you understand it. The two sentences evoke markedly different associations. “Italy won” evokes thoughts of the Italian team and what it did to win. “France lost” evokes thoughts of the French team and what it did that caused it to lose, including the memorable head butt of an Italian player by the French star Zidane. In terms of the associations they bring to mind— how System 1 reacts to them—the two sentences really “mean” different things. The fact that logically equivalent statements evoke different reactions makes it impossible for Humans to be as reliably rational as Econs. Download 4.07 Mb. Do'stlaringiz bilan baham: |
