Note(s): a Low ethnocentric group is those who scored below the median of the consumer ethnocentrism variable, while the other is the high ethnocentric group. b Scanning (dummy variable) takes the value of 1, when respondents chose to scan the traceability QR code, and 0 otherwise. c Reading time (continuous variable) accounts for the reading time of the extra traceability information page if respondents chose to scan the traceable QR code. d Reading time is equal to 0 if the respondents did not choose to scan, the only QR scanners sample excludes those who did not scan the QR code
