General Science / Is there an auditory equivalent of an optical illusion?
« on: 29/07/2008 03:15:16 »I think a lie or an error might qualify as a logical illusion - this would be a statement that is presented as true but is in fact untrue.
Yes, but in a good optical illusion you have the clear perception, even after being convinced that the reality is different, your brain may still gives the wrong idea. Also, an illusion doesn’t need to define the validity of a premise. In contrast, a lie by itself does not necessarily give the idea of being true; a false statement needs to be flawed either in the logic or in the validity of the premises.

I don't understand enough about how an illusion works, but for example in the leaning towers illusion, the same information repeated two times gives generates the perception of a whole that is different from the parts. I may understand that I am been deceived, and may understand how, but I still see the illusion.
Also an illusion is "clean" in the sense that it doesn't overwhelm with information, is not like looking to a maze, but may be more like placing the information in tricky way, like Bilbo Bolson saying; "I don't know half of you half as well as I should like; and I like less than half of you half as well as you deserve".
My guess is that an informal logical fallacy (http://en.wikipedia.org/wiki/Informal_fallacy) is what we could call a logical illusion, but I am not sure. Probably my question is then:
Are logical fallacies equivalent to optical or acoustical illusions in the way the brain is deceived?
