They give people a financial incentive to seek the truth and then protect them with the twin shields of pseudonymity and decentralization.

A transparent exchange with no limit on what you can bet on, no max limits on the amount you can bet and no rollover requirements. Oftentimes, the people in these crowds are skewed in their independent judgements due to peer pressure, panic, bias, and other breakdowns developed out of a lack of diversity of opinion.

One of the main constraints and limits of the wisdom of crowds is that some prediction questions require specialized knowledge that majority of people do not have.

Due to this lack of knowledge, the crowd's answers can sometimes be very wrong. The second market mechanism is the idea of the marginal-trader hypothesis.

In early , researchers at MIT developed the "surprisingly popular" algorithm to help improve answer accuracy from large crowds. The method is built off the idea of taking confidence into account when evaluating the accuracy of an answer.

The method asks people two things for each question: What they think the right answer is, and what they think popular opinion will be.

The variation between the two aggregate responses indicates the correct answer. The effects of manipulation and biases are also internal challenges prediction markets need to deal with, i.

Prediction markets may also be subject to speculative bubbles. There can also be direct attempts to manipulate such markets.

In the Tradesports presidential markets there was an apparent manipulation effort. An anonymous trader sold short so many Bush presidential futures contracts that the price was driven to zero, implying a zero percent chance that Bush would win.

The only rational purpose of such a trade would be an attempt to manipulate the market in a strategy called a " bear raid ". If this was a deliberate manipulation effort it failed, however, as the price of the contract rebounded rapidly to its previous level.

As more press attention is paid to prediction markets, it is likely that more groups will be motivated to manipulate them. However, in practice, such attempts at manipulation have always proven to be very short lived.

In their paper entitled "Information Aggregation and Manipulation in an Experimental Market" , [23] Hanson, Oprea and Porter George Mason U , show how attempts at market manipulation can in fact end up increasing the accuracy of the market because they provide that much more profit incentive to bet against the manipulator.

Using real-money prediction market contracts as a form of insurance can also affect the price of the contract. For example, if the election of a leader is perceived as negatively impacting the economy, traders may buy shares of that leader being elected, as a hedge.

These prediction market inaccuracies were especially prevalent during Brexit and the US Presidential Elections.

Even until the moment votes were counted, prediction markets leaned heavily on the side of staying in the EU and failed to predict the outcomes of the vote.

According to Michael Traugott , a former president of the American Association for Public Opinion Research , the reason for the failure of the prediction markets is due to the influence of manipulation and bias shadowed by mass opinion and public opinion.

Similarly, during the US Presidential Elections, prediction markets failed to predict the outcome, throwing the world into mass shock.

Like the Brexit case, information traders were caught in an infinite loop of self-reinforcement once initial odds were measured, leading traders to "use the current prediction odds as an anchor" and seemingly discounting incoming prediction odds completely.
