Moral Foundations Theory (MFT) predicts that moral behaviour reflects at least five foundational traits, each hypothesised to be heritable. Here, we report two independent twin studies (total n = 2020), using multivariate multi-group common pathway models to test the following three predictions from the MFT: (1) The moral foundations will show significant heritability; (2) The moral foundations will each be genetically distinct and (3) The clustering of moral concerns around individualising and…

Remapping the foundations of morality: Well-fitting structural model of the Moral Foundations Questionnaire

Moral foundations theory posits five moral foundations, however 5-factor models provide poor fit to the data. Here, in five studies, each with large samples (total N = 11,496), we construct and

Meta-analysis of the heritability of human traits based on fifty years of twin studies

TLDR
This study provides the most comprehensive analysis of the causes of individual differences in human traits thus far and will guide future gene-mapping efforts.

Using Moral Foundations to Predict Voting Behavior: Regression Models from the 2012 U.S. Presidential Election

The current research examined the ability of moral foundations to predict candidate choice in the 2012 U.S. Presidential Election across three studies. Results indicated that endorsement of moral

Mapping the moral domain.

TLDR
The Moral Foundations Questionnaire is developed on the basis of a theoretical model of 5 universally available (but variably developed) sets of moral intuitions and convergent/discriminant validity evidence suggests that moral concerns predict personality features and social group attitudes not previously considered morally relevant.

DEMONSTRATING THE VALIDITY OF TWIN RESEARCH IN CRIMINOLOGY

In a recent article published in Criminology, Burt and Simons (2014) claimed that the statistical violations of the classical twin design render heritability studies useless. Claiming quantitative

Liberals and conservatives rely on different sets of moral foundations.

TLDR
Across 4 studies using multiple methods, liberals consistently showed greater endorsement and use of the Harm/care and Fairness/reciprocity foundations compared to the other 3 foundations, whereas conservatives endorsed and used the 5 foundations more equally.

Intuitive Ethics and Political Orientations: Testing Moral Foundations as a Theory of Political Ideology

Originally developed to explain cultural variation in moral judgments, moral foundations theory (MFT) has become widely adopted as a theory of political ideology. MFT posits that political attitudes

A Test of the Equal Environment Assumption (EEA) in Multivariate Twin Studies

TLDR
The analysis of spatial ability and aggression indicated no detectable violation of theequal environment assumption, and multivariate data provide sufficient information to test the validity of the EEA.

Are Extended Twin Family Designs Worth the Trouble? A Comparison of the Bias, Precision, and Accuracy of Parameters Estimated in Four Twin Family Models

TLDR
It is found the classical twin design does a decent job of estimating broad sense heritability, but CTD estimates of shared environmental effects and the relative importance of additive versus non-additive genetic variance can be biased.

Moral foundations and political orientation: Systematic review and meta-analysis.

TLDR
The relationship of morality and political orientation is investigated by focusing on the influential results showing that liberals and conservatives rely on different moral foundations, supporting both the bidimensional model of political orientation and the findings that the dimensions are often strongly correlated.
