200 days following the Sewol ferry tragedy, the legislature finally formulated a bill for the investigation of the disaster to which the Sewol families have given their consent. The prolonged passage of the bill – due largely to the victim families’ resistance to previous iterations of the Sewol investigation bill – underlines political distrust of President Park and her Saenuri Party government as well as the opposition alliance, the New Political Alliance for Democracy (NPAD), to represent the interests of the Sewol victims’ families. This raises the questions: what is political trust? What are the effects of political distrust in an emergent democracy such as South Korea?
What is political trust? Political trust refers to public confidence in the facility and capacity of the political system to deliver regularly political goods that include contestable political succession, regularized competition, civil and political liberties, and freedom of association and expression. Political trust, then, rests on the design and workings of the “institutions, structures and processes” to produce quality political goods “even if left untended,” based on principles of fairness and accountability. 
What are the effects of political distrust? Studies show that political trust – derived from institutional performance – underpins the distinction of political performance from government performance so that it buffers the political system from the pressures of immediate outputs. Conversely, political distrust means that the political system is under pressure to produce immediate outputs, while the concomitant lack of vested interests in the political system means that the public is more willing to engage in non-compliant behaviors, including civil disobedience and protests, to demand for these outputs. Political distrust in an emergent democracy such as South Korea, then, potentially jeopardizes democracy in the country.
The regular rallies and protests in Seoul and outside the Blue House – including hunger strikers – demanding a full, independent investigation of the Sewol tragedy signal the political distrust with a political system that has given rise to regulatory lapses that endanger wellbeing.
Importantly, the political distrust extends to the opposition alliance: indeed, the opposition NPAD alliance’s effort to push through previous iterations of the Sewol bill faced bitter opposition from the Sewol victims’ families and felled the recently-elected NPAD floor leader, Park Young-sun. Clearly, the political distrust means that the opposition – like the government – is faced with pressures of immediate outputs and performance.
The road to build political trust is clear: focus on institution-building that delivers political goods rather than public or private goods such as economic performance. But there are clear trade-offs from such a focus: the political system may be buffered but the parties and the government remain vulnerable to voters’ expectations of performance and subsequent rejection for failing to deliver. The government and opposition may do well to note that, as they struggle with these trade-offs, the democratic health of the country remains at stake.
