Is it possible to infer information about public opinion by looking at how the media discuss controversial technoscientific public issues? We conduct content analysis on media coverage of nuclear power in Italy in the years 1992–2012 and compare it with longitudinal public opinion surveys. By treating a large amount of textual data and applying an innovative methodology based on indicators of the presence of ‘risky terms’, that is, keywords referring to the issue of risk and danger, very high correlation has been found between media discourse on risk and opposition within public opinion. The analysis is conducted testing as a preliminary step Mazur’s hypothesis on quantity of coverage and opposition towards controversial technoscience. Then, risk content measures are used in order to gain stronger correlations between media and public attitudes towards nuclear power.
