An American, a Frenchman and a physicist were talking about some unusual weather. “It was twice as hot this afternoon as this morning”, said the American, “the temperature went up from 40 to 80 degrees.” The Frenchman interjected: “That’s in Fahrenheit. In Celsius, it was six times hotter.” The physicist was scornful. “On the only really scientific measure, the Kelvin scale, the increase was a piffling 5 percent.”
Another recession could be about to arrive, or even be here already. Some people fear it will be as bad as the last one, which reduced output in the U.S., euro zone and Japan by 5.1, 5.5 and 8.9 percent respectively. Those GDP declines are often described in cataclysmic terms: staggering, disastrous or traumatic. Such words are vast – and dangerous – exaggerations.
