A team in the University of London found that people who went with their initial response on a test of visual perception (questions included picking out an anomaly in a pattern of symbols) did better than those who were given more time to ponder.
the subconscious brain recognized a rotated version of the same symbol as different, the conscious brain reasoned that 'an apple is still an apple whether rotated or not', the researchers on the project
. When the subjects had time to engage their higher-level functions
of relying on their intuitive responses, they were more
to be wrong.
