When I sneeze, people often say to me – I know not why – “bless you”. I do not reciprocate when others sneeze, for I refuse to subscribe to any form of superstition.
It follows that my well-wishers clearly are superstitious. Therefore, my exceptional politesse dictates that I ought to offer them a blessing whenever they expel extraneous sinal mucus.
But perhaps the whole of humankind believes that everyone else is superstitious and so this absurd tradition continues between people who ought to know better, each of them fearing that they will cause offence. It is an awful superstition-fearing spiral. How, dear economist, to break out of it?
