This image has been around for over 100 years. In 1899, American psychologist Joseph Jastrow used it in research he was conducting about perception and mental activity. What he discovered is that those who were able to easily change their perception between the two animals, had faster working brains than those who were slower and had trouble switching between the two.
His conclusion was that the more creative a person is, the faster they are able to see the image change from duck to rabbit. This optical illusion can therefore help to assess how creative of an individual you are by looking at 1) what you see first and, 2) how fast you saw it. Try it now!
