I am going to preface this essay by admitting that I haven’t
gambled in a very long time, and for some reason when I initially thought of
the “doubling down” metaphor I only had a nebulous idea that it applied to card
games. So, after typing this sentence I
googled it and found that it relates, exclusively, to blackjack. I assume I’m in the minority of people who
were unaware of this, however, there are lots of expressions we are carelessly
using without any real knowledge of their etymological and, in the case of
“double down,” metonymic origins.
