While media polls failed miserably in predicting the results of the Taipei and Kaohsiung mayoral elections, one group of academics and political soothsayers prophesied the outcome with stunning accuracy.
Their nearly dead-on predictions were no accident, they insist, nor were there any crystal balls involved.
Just good science was behind their forecasts, they said, adding that they would soon unveil more on-the-mark political predictions -- including the winner of next year's presidential election.
"It's like a futures exchange market," said Academia Sinica political analyst Lin Jih-wen (
"The same market mechanisms as in a bourse are harnessed to integrate biases and diverse outlooks on the future and produce a specific prediction," he said.
Prediction market
Like prediction markets in the US, which boast steady track records of accurately predicting everything from the next president to the next Oscar winner, Taiwan's first prediction market is a speculative bourse whose assets' final cash value is tied to a specific future event.
Speculators bet on various possible outcomes whose market value is interpreted as the probability of that outcome occurring, said Swarchy Co official Liu Chia-kai (
The final market projection for Democratic Progressive Party (DPP) Taipei mayoral candidate Frank Hsieh's (謝長廷) share of the vote in December's election, for example, was off by merely a few percentage points, said panelists.
The market's predicted winner of the Taipei mayoral election -- Chinese Nationalist Party (KMT) candidate Hau Long-bin (郝龍斌) -- was similarly pegged by speculators as earning a vote share that missed the mark by only one percentage point.
"Contrast that with media polls," Liu said. "They were all off in their forecasts of voting shares by around ten percentage points, and even failed to predict the winner."
So why was the prediction market so accurate?
Informed individuals
Center director and NCCU economics professor Lin Hsin-yi (林馨怡) told reporters that when a large group of informed individuals with a material stake in how the event that their betting on, unfolds, they tend to actively and squarely assess the circumstances.
Liu called such statistical accuracy "tapping the wisdom of the masses."
Polls, on the other hand, rely on the responses of often apathetic or even untruthful participants, said Academia Sinica researcher Hsu Yung-ming (徐永明), adding that media should analyze both polls and prediction market trends in sizing up political developments.
"Polls are useful because they can roughly tell us the political thinking among certain segments of society, while prediction markets can tell us, with a reasonable degree of accuracy, what's going to happen," Lin Jih-wen said, adding that prediction markets' weakness lies in their inability to demonstrate why they have reached certain conclusions.
More than half of the bamboo vipers captured in Tainan in the past few years were found in the city’s Sinhua District (新化), while other districts had smaller catches or none at all. Every year, Tainan captures about 6,000 snakes which have made their way into people’s homes. Of the six major venomous snakes in Taiwan, the cobra, the many-banded krait, the brown-spotted pit viper and the bamboo viper are the most frequently captured. The high concentration of bamboo vipers captured in Sinhua District is puzzling. Tainan Agriculture Bureau Forestry and Nature Conservation Division head Chu Chien-ming (朱健明) earlier this week said that the

NAMING SPAT: The foreign ministry called on Denmark to propose an acceptable solution to the erroneous nationality used for Taiwanese on residence permits Taiwan has revoked some privileges for Danish diplomatic staff over a Danish permit that lists “Taiwan” as “China,” Eric Huang (黃鈞耀), head of the Ministry of Foreign Affairs’ Department of European Affairs, told a news conference in Taipei yesterday. Reporters asked Huang whether the Danish government had responded to the ministry’s request that it correct the nationality on Danish residence permits of Taiwanese, which has been listed as “China” since 2024. Taiwan’s representative office in Denmark continues to communicate with the Danish government, and the ministry has revoked some privileges previously granted to Danish representatives in Taiwan and would continue to review
The first bluefin tuna of the season, brought to shore in Pingtung County and weighing 190kg, was yesterday auctioned for NT$10,600 (US$333.5) per kilogram, setting a record high for the local market. The auction was held at the fish market in Donggang Fishing Harbor, where the Siaoliouciou Island-registered fishing vessel Fu Yu Ching No. 2 delivered the “Pingtung First Tuna” it had caught for bidding. Bidding was intense, and the tuna was ultimately jointly purchased by a local restaurant and a local company for NT$10,600 per kilogram — NT$300 ,more than last year — for a total of NT$2.014 million.
