The quote

The apparent duck becomes an obvious rabbit

refers to a paradigm shift. I've only seen one paper including it, and the author uses it as if it is common. Is it used elsewhere, or with a different comparison?

Limited as Google is as a tool for lexical research, the fact that Googling the phrase fails to turn up anything beyond this question suggests it's unique to the author. I don't think they've used it as though it's common, though; it's simply a reference to a relatively well-known visual paradigm shift.



At least in philosophy, the duck-rabbit illusion was first made famous by Wittgenstein in his "Philosophical Investigations": http://en.wikipedia.org/wiki/Philosophical_Investigations

  • also see en.wikipedia.org/wiki/Joseph_Jastrow the feminist Gilligan talks about it and it is discussed in relation to the philosophy of Merleau-Ponty's
