Seeing what we expect to see

It is funny how our brains work. I saw a political cartoon this morning and initially thought that the cartoonist had finally seen the light regarding the danger Islam presents in Europe. Alas, my brain saw what it wanted to see and further study of the cartoon revealed a totally different message.
Just like when we see shapes in the clouds our brains try to make sense and allocate meaning when we view a cartoon.
This is the shape that is usually at the front of my mind these days so this is the shape that my brain saw in the cartoon.
turkeyHere is the cartoon that I saw.
