Brain can be trained to predict winner in sporting events

Your brain can be trained to predict the winner of a sporting event with accuracy close to that of a statistical computer programme, researchers say.
Researchers at University College London and the University of Montreal have found a way to train the brain to accurately predict the outcome of an event, for example a baseball game, by giving subjects idealised scenarios that always conform to statistical probability.
In the study, participants who had been trained on statistically idealised data vastly improved their ability to predict the outcome of a baseball game.
In normal situations, the brain selects a limited number of memories to use as evidence to guide decisions. As real-world events do not always have the most likely outcome, retrieved memories can provide misleading information at the time of a decision.

"Providing people with idealised situations, as opposed to actual outcomes, 'cleans' their memory and provides a stock of good quality evidence for the brain to use," said Dr Bradley Love from UCL Department of Cognition, Perception and Brain Sciences and lead author of study.
In the study, published in Proceedings of the National Academy of Sciences, researchers programmed computers to use all available statistics to form a decision - making them more likely to predict the correct outcome.

By using all data from previous sports leagues, the computer's predictions always reflected the most likely outcome.
Next, researchers 'trained' the brains of participants by giving them a scenario which they had to predict the outcome of. Two groups of subjects, those given actual outcomes to situations and those given ideal outcomes were trained and then tested to compare their progress.

The scenarios consisted of games between two Major League baseball teams. Participants had to predict which team would win and were told if their prediction was correct. Those in the 'actual' group were told the true outcome of the game and those in the 'ideal' group were given fictional results.
Prior to participants' predictions, the teams had been ranked in order based on their number of wins. For the ideal group, researchers changed the results of the match so the highest ranking team won regardless of the true outcome.
This created ideal outcomes for the subjects as the best team always won, which of course does not happen in reality.

Participants in the experiment were tested by being asked to predict the outcomes for the rest of the matches played in the league.
Even though the 'ideal' group had been given incorrect data during training, they were significantly better at predicting the winner. After ideal outcome training, the study showed that 'ideal' subjects had greatly enhanced their skills and were comparable with the optimised model when predicting baseball game outcomes.
