Using a pre-registered original survey experiment conducted among members of a nationally-representative high-quality Dutch panel, we studied whether exposure to proposed abolishment of EU member states’ right of veto leads to more negative EU attitudes. 3/7

Informed by recent in-depth qualitative research, we also analysed whether this effect is stronger among citizens with more populist attitudes. Additionally, we tested if exposure through a Eurosceptic newspaper either aggravates or abates the extent to which the message leads to Euroscepticism. 4/7
