[Inside Chodong] Let's Fix the "Myung Taegyun's Magic Box" Opinion Polls This Time

Amid Manipulation Allegations, Doubts Over Polls Grow
From Reference Tool to Decision-Making Authority
Stronger Oversight Needed, Role of Polls Should Be Reduced

Public opinion polls are often called the barometer of public sentiment. Just as high pressure brings clear weather and low pressure brings cloudy skies, pressure itself has become a kind of measure of the weather, which is why the term is used metaphorically. However, high pressure does not always mean clear skies, nor does low pressure always mean cloudy weather. Similarly, public opinion polls do not directly represent the public’s views. They are merely one method of gauging trends in public opinion, but at some point, polls shifted from being a “reference material” to a “decision-making” tool. This is why Myung Tae-gyun, who claims to be a polling expert, was able to exert influence in the political arena.

Opinion polls carry risks of bias and error due to various factors such as question design, survey methods, political prejudices toward the poll requester or polling agency known as the house effect, among others. In the U.S. presidential election, the issue of “shy Trump” voters?those who support Donald Trump but do not disclose it?has caused headaches in trying to accurately gauge voter sentiment every election. In South Korea, we also experienced a “neck-and-neck” poll regarding the October 16 by-election for the Busan Geumjeong District Office, but the election result ended with the ruling party candidate winning by a 22.1 percentage point landslide. This shows the limitations of polls in accurately capturing actual public opinion. Moreover, recent controversies involving Myung have increased doubts about the reliability of opinion polls.

The problem is that the role of opinion polls in our politics is growing increasingly significant. Amid political polarization, political discussions have become taboo even among family members, making polls a window through which people can glimpse others’ political leanings. Naturally, the mere fact that a poll shows someone “leading” or “rising” has come to shape public opinion itself.

Furthermore, in the process of nominating public office candidates?a key role of political parties?opinion polls are deciding election outcomes. In the last general election, both the People Power Party and the Democratic Party actively used polls at every decision point, from cutting off incumbent lawmakers to the actual primaries. The intention was to return the nomination process, previously divided among factions, to the people, but the ambiguity of probabilistic statistics and the risk of manipulation remain unavoidable. Statistically, differences within the margin of error cannot determine superiority. Yet in nominations, these numbers decide victory or defeat. Moreover, unlike public opinion polls for publication, party polls have no obligation for prior reporting, leaving no proper oversight. Because of this, candidates who feel unfairly treated have no choice but to request reconsideration or engage in lawsuits and accusations, even if it means opposing their party.

While the controversy may have started with Myung, the problem with opinion polls had already become deeply rooted. How should this be resolved?

First, a stricter system of checks and monitoring for opinion polls must be established. The Central Poll Deliberation Commission (CPDC) is preparing measures to significantly reduce exemptions from the obligation of prior reporting related to polls. This must be addressed through legislation, but the key lies in whether political parties and the media will accept reform. The National Assembly is considering reform proposals such as restricting the qualifications of polling operators and strengthening penalties. There is also discussion about elevating the status of the CPDC under the National Election Commission. A committee of about 20 members cannot effectively correct the increasingly chaotic polling issues.

More fundamentally, reliance on opinion polls should be reduced. Academia points out that “the problem is using them like a magic spell.” The inclusion of polls in the political process is indeed because they save time and cost. Polls should return to their original role as reference materials. Cheap and fast is not always the best.
