Irina Vartanova will present two projects that bring new insights into the understanding of moral opinion dynamics using the moral argument theory:

1) A cross-cultural test of this theory shows that the opinion dynamic caused by the connection between moral opinions and their arguments are highly similar between three western countries with different political cultures (the US, the UK, and Sweden). 

2) The theory helps to explain why cognitive ability is linked to the likelihood of holding certain liberal opinions. Certain moral positions are more popular among liberals because they are better connected to the types of arguments that liberals recognise as relevant. Cognitive ability enters the picture because in practice, it is not trivial to see the difference between different kinds of moral arguments. The novel predictions arising from the model is strongly supported by GSS data.
