Legitimacy Disputes and Social Amplification of Perceived Risk
Unformatted Document Text:  Legitimacy & Social Amplification of Risk Perceptions     21   Answer to Research Question 2 Research Question 2: How have risk perceptions changed in different time periods as a function of government’s risk communication? A chi-square test of independence was performed to examine the perceptions of risk during the four different phases of the issue debate. As can be seen by the frequencies cross tabulated in Table 2, there is a significant difference of perceived risk about MCD during the four different stages of issue development, χ 2 (6, N=320)=39.02, p < .0001. The perceived risk was the highest in the first stage right after the first MBC PD Notebook was aired. More than 74.6% of bloggers expressed high risk of MCD while about 12 % of them perceived the risk as low. In the second period of risk communication, the percentage of bloggers who perceived the risk as low increased to 25.5 percent. It is also noteworthy that “not known yet” attitudes has increased in the second period, implying that people may have put some doubt on MBC PD Notebook’s claims. In the period 2, there was a huge turnout of bloggers who came up with the scientific data related to MCD. An additional data analysis, however, show that bloggers who claimed the low risk or “now-known-yet” attitude toward the MCD by having the imported beef tended to oppose to the government decision to reopen the door for the US beef. Like those who have high risk of MCD, they were also critical of government decision to repeal the ban on the US beef import. It is hard to say whether or not the government’s official responses to MBC PD Notebook’s claims along with conservative media’s criticism affected those bloggers’ “unknown” or “inconclusive” perception about the risk, even though there was enormous effort made by Korean government and conservative media to discredit MBC PD Notebook’s claims and its sources.

Legitimacy & Social Amplification of Risk Perceptions   
Answer to Research Question 2 
Research Question 2: How have risk perceptions changed in different time 
periods as a function of government’s risk communication?  
A chi-square test of independence was performed to examine the perceptions of 
risk during the four different phases of the issue debate. As can be seen by the 
frequencies cross tabulated in Table 2, there is a significant difference of perceived risk 
about MCD during the four different stages of issue development, χ
(6, N=320)=39.02, p 
< .0001. The perceived risk was the highest in the first stage right after the first MBC PD 
Notebook was aired. More than 74.6% of bloggers expressed high risk of MCD while 
about 12 % of them perceived the risk as low. In the second period of risk 
communication, the percentage of bloggers who perceived the risk as low increased to 
25.5 percent. It is also noteworthy that “not known yet” attitudes has increased in the 
second period, implying that people may have put some doubt on MBC PD Notebook’s 
claims. In the period 2, there was a huge turnout of bloggers who came up with the 
scientific data related to MCD. An additional data analysis, however, show that bloggers 
who claimed the low risk or “now-known-yet” attitude toward the MCD by having the 
imported beef tended to oppose to the government decision to reopen the door for the US 
beef. Like those who have high risk of MCD, they were also critical of government 
decision to repeal the ban on the US beef import. It is hard to say whether or not the 
government’s official responses to MBC PD Notebook’s claims along with conservative 
media’s criticism affected those bloggers’ “unknown” or “inconclusive” perception about 
the risk, even though there was enormous effort made by Korean government and 
conservative media to discredit MBC PD Notebook’s claims and its sources.
