Purpose This paper aims to introduce a cross-cultural study of the views and implications of Snowden’s revelations about NSA/GCHQ surveillance practices, undertaken through surveys administered in eight countries. The aims and academic and social significance are explained, and justification is offered for the methods used. Design/methodology/approach Pilot surveys were deployed in two countries, following which revised versions were deployed in eight countries. Quantitative analysis of suitable answer sets and quantitative analysis were performed. Findings Through the pilot survey studies conducted in (...) Japan and Spain, the academic significance and meaningfulness, as well as social significance of the project, were confirmed. Practical implications The results of the cross-cultural study are expected to contribute not only to the advance of surveillance study but also to the enhancement of ordinary, non-technical people’s awareness of state surveillance and their proactive approach to protecting their own rights and dignity from covert intrusion by government agencies. Originality/value This paper clarifies the importance and methodologies of investigating the social impact of Snowden’s revelations on youngsters’ attitudes toward privacy and state surveillance in a cross-cultural analysis framework. Although a few other studies have assessed the impact of Snowden’s revelations, these have mostly focussed on the USA, so this is the only study to date considering that impact on a broad international scale, using highly similar surveys to ensure comparability.
