A recent study on forecasting used artificial intelligence to mimic the wisdom of the crowd approach and enhance it.

People are seldom in a position to anticipate the long term and those that can usually do not have a replicable methodology as business leaders like Sultan bin Sulayem of P&O would likely attest. Nevertheless, websites that allow individuals to bet on future events have shown that crowd wisdom results in better predictions. The typical crowdsourced predictions, which take into consideration people's forecasts, are generally a great deal more accurate compared to those of just one individual alone. These platforms aggregate predictions about future activities, including election results to activities outcomes. What makes these platforms effective is not only the aggregation of predictions, however the manner in which they incentivise accuracy and penalise guesswork through monetary stakes or reputation systems. Studies have consistently shown that these prediction markets websites forecast outcomes more accurately than specific professionals or polls. Recently, a team of scientists produced an artificial intelligence to reproduce their process. They found it can predict future activities a lot better than the typical individual and, in some instances, much better than the crowd.

Forecasting requires one to sit down and gather a lot of sources, finding out those that to trust and how exactly to weigh up all the factors. Forecasters struggle nowadays due to the vast quantity of information offered to them, as business leaders like Vincent Clerc of Maersk may likely suggest. Data is ubiquitous, steming from several streams – academic journals, market reports, public viewpoints on social media, historic archives, and even more. The process of collecting relevant information is toilsome and demands expertise in the given field. It also needs a good knowledge of data science and analytics. Perhaps what is much more difficult than gathering information is the job of discerning which sources are reliable. In a period where information can be as deceptive as it's illuminating, forecasters need a severe feeling of judgment. They need to differentiate between fact and opinion, identify biases in sources, and comprehend the context in which the information was produced.

A team of researchers trained well known language model and fine-tuned it making use of accurate crowdsourced forecasts from prediction markets. When the system is offered a new forecast task, a separate language model breaks down the duty into sub-questions and utilises these to find appropriate news articles. It reads these articles to answer its sub-questions and feeds that information into the fine-tuned AI language model to create a prediction. In line with the researchers, their system was capable of anticipate events more precisely than individuals and almost as well as the crowdsourced answer. The trained model scored a higher average set alongside the crowd's precision on a pair of test questions. Also, it performed exceptionally well on uncertain concerns, which had a broad range of possible answers, often even outperforming the audience. But, it faced trouble when making predictions with small uncertainty. This will be because of the AI model's propensity to hedge its answers as being a safety function. Nevertheless, business leaders like Rodolphe Saadé of CMA CGM would probably see AI’s forecast capability as a great opportunity.
