Some super-forecasters are just everyday people, from all walks of life, who happen to have astonishingly perceptive judgements. Other gifted individuals include super-tasters , who have an intense perception of flavour and super memorisers who naturally recall events from almost every day of their lives.
Those talents might be largely down to our genes, whereas forecasting ability should, in theory, be down to experience and learned skill. Yet top political experts tend to perform very poorly at crystal ball gazing: Philip Tetlock at the University of Pennsylvania has found they do only slightly better than chance.
Intelligence agencies have a keen interest in research on forecasting Getty Images. Needless to say, military intelligence agencies have been watching closely. One of the main aims was to see whether certain forecasters were consistently good. At the end of the second year, their performance was up to four times more accurate than other participants. Although political expertise may have helped, they came from a variety of professions. As you might expect, these elite forecasters tended to score better on measures of intelligence than the other participants.

Changizi realized the same future-seeing process could explain several other types of illusions. In what he refers to as a "grand unified theory," Changizi organized 50 kinds of illusions into a matrix of 28 categories.
The results can successfully predict how certain variables, such as proximity to the central point or size, will be perceived. Changizi says that finding a theory that works for so many different classes of illusions is "a theorist's dream.
Most other ideas put forth to explain illusions have explained one or just a few types, he said. The theory is "a big new player in the debate about the origins of illusions," Changizi said. IE 11 is not supported.
