If you're not sure what "numeracy" is, you should probably pick up The Economist's Guide to Business
"Numeracy" is that state of being numerate, which means you can count. Nowadays, at least in the British
press, its scope of the term has expanded to "being sophisticated about the meaning of concepts or
arguments presented numerically" or, possibly, being unintimidated by the avalanche of numbers flowing
through our society's channels of communication.
Traders are subjected to numerical intimidation as much as anyone, particularly with the increasingly
abstract indicators being cobbled together these days. At its extreme, today's trend asks us to interpret the
meaning of the weights in a neural net, a certain exercise in skepticism.
