Inductive reasoning is what enables us human beings to master new and uncertain situations by making assumptions and generalisations and thus cope with the complexities of our world. Stereotyped thinking is, after all, what structures our thinking processes and what makes them quick and efficient. But it is also a feature of the human brain that makes for optical illusions in the first place: every time something doesn’t match our stereotypes in the least :). The perfect example is the following photo by Austrian photographer Bela Borsodi. A photomontage or one single photo?
Even though we know that we are dealing with carefully arranged objects designed to bring about just that effect, certain assumptions (such as the impossibility of converse colours at close range that are separated by straight lines) are so deeply wired that our brain still refuses to accept them. Even after close consideration. Watching the arrangement from a more favourable viewpoint, the “ape brain 2.0” instantly recognises what’s going on 😉
Those of you who want to know how this though nut came into being, please have a look at the following making-of video. But be warned, afterwards it might be hard to trust one’s own senses and mind. 😉
