Mitt Romney is a quantum CEO, the Schrödinger’s Cat of private equity: From 1999 to 2002, he both was and was not the chief executive officer and sole owner of a powerful Bain Capital investment fund. After that period, Romney’s surrogates explain, he “retroactively” retired from this post. But, as Schrödinger’s famous thought experiment reminds us, just because you find a retroactively dead cat doesn’t mean he wasn’t previously simultaneously alive and dead.
