Origin of the Organization


The rise of falsehoods
The prevalence of social media has increased the number of information channels accessible to the public. Given the abundance of information received, people spend less time verifying the authenticity of such information. According to the National Development Council, the percentage of internet users who do not verify facts rose from 34.8% in 2018 to 44.9% in 2019.

The decline of truth

With the popularity of wireless network in recent years, changes in media ecologies have prompted news outlets to produce more time-sensitive items, and live streams and satellite news gatherings have become commonplace. Unverified statements by politicians are often disseminated rapidly. A digital news report released by The Reuters Institute for the Study of Journalism revealed that as much as 40% of the public believe that politicians are the main source of misinformation. Digital News Report 2022 has shown that trust in news in Taiwan is low by 27%.

A third-party verification mechanism

Social media should take responsibility for the rise of misinformation. Public–private partnerships established to serve as an independent and impartial third-party verification mechanism are the current prevailing practice for censoring misinformation.

Organization Information

The Taiwan Society for Targeting Misinformation (TSTM) is founded on social diversity and endeavors to present the truth, unadulterated by political views or prejudices. We uphold the principles of independence and justice in our practices to provide the public with references that can be used to judge major matters of public interest. Our services extend to the verification of the truthfulness and accuracy of information; we do not make value judgements.

We receive fact-checks information provided by the public and information reported in the news, paying attention to relevant information in mass and social media. Because of the considerable volume of information and our limited time and staffing resources, we prioritize the fact-checking of information that is newsworthy and of the most value.

Purpose and scope of service

The Taiwan Society for Targeting Misinformation (TSTM) shall establish a steering committee (hereafter “the Committee”) comprising five to nine members. The responsibilities of the Committee include determining TSTM operational guidelines and reviewing and approving major decisions. The Committee chairperson shall be elected among the committee members.

TSTM shall establish an editorial team comprising one editor-in-chief, one lead editor, and several fact-checkers. On the basis of the steering committee’s decisions, the editor-in-chief shall comprehensively manage TSTM operations in fact-checking misinformation and present appeals and feedback from the general public to the Committee for deliberation. The outcomes of the Committee’s deliberations shall be released to the public.

Information-Screening Criteria

TSTM screens information according to the following criteria.

  1. Whether the information is based on verifiable fact(s): TSTM only fact-checks content and accounts that can be verified and does not fact-check opinions.
  2. Information dissemination speed and capacity: TSTM prioritizes the fact-checking of information that is rapidly and widely disseminated.
  3. Impact of the information topic: TSTM prioritizes the fact-checking of information that has an immediate, direct, and significant influence impact on matters of public interest.
  4. In view of TSTM’s scale and staffing, information that requires fact-checking but cannot be processed immediately is listed as a future priority.

To ensure that our fact-checking team remains impartial when reviewing appeals from the public, our fact-checking guidelines state that, in the event of the fact-checking team’s disagreement with a submitted appeal, the appeal and argument for the dissent shall be presented to the steering committee. The steering committee shall then make the final determination.
