Ex-president George W. Bush inesperately contributed to science when he was able to duck flying shoes thrown at him by an Iraqi reporter in December in Bagdad as reveals the study published this month in the magazine Current Biology by two neurologists of Washington University.

Bush reflexes and the impassivity that al-Maliki, the Iraqi primer Minister, who was next to the US president, showed, support the theory of the two scientists that claims that two independent pathways in the human visual system exist.
One system guides the actions and the other the perception. The interesting part is that the first one allows the brain to “see” thing that the eyes don’t perceive, says Jeffrey Lin, first author of the study.

“When we throw two balls at you with very similar trajectories, they may look the same to your perceptual system, but your brain can automatically calculate which one is more threatening and trigger a dodging motion before you’ve even realized what has happened,” said Lin.

That explains why in the video al-Maliki doesn’t flinch “his brain has perceived that the shoe is not a threat for him. But Bush’s brain has categorized the shoe as threatening and triggers an evasive dodge, all within a fraction of a second”.

The scientists performed several experiments with students to demonstrate their theory, and the incident in Bagdad was an inesperate and welcomed example in real life.
