From 2015... A foundation beam for studying morality from a personological point of view: Are individual differences in moral behaviors and thoughts consistent? Peter Meindl et al. Journal of Research in Personality, Volume 59, December 2015, Pages 81-92. https://doi.org/10.1016/j.jrp.2015.09.005

Highlights
•    Past research suggests moral behavior is highly inconsistent.
•    This leaves little room for a personological approach to morality.
•    We tested the consistency of real world morality via two experience sampling studies.
•    Results reveal a surprisingly large degree of moral consistency.
•    Personality appears to have the potential to profoundly impact moral life.

Abstract: Morality is a topic of burgeoning scientific interest, and the relevance of personological factors to moral behavior has interdisciplinary implications for the social sciences, public policy, and philosophy. However, relatively little research has investigated the role of personological factors in moral life, perhaps because of lingering skepticism about the robustness of moral traits. The purpose of this paper is to determine whether morality is consistent across many occasions of everyday life, implying that personological factors play an important role in moral behavior. A novel method of assessing moral behaviors was developed and employed in two experience sampling studies (4075 total observations). Results showed that moral behavior is consistent in many different ways, suggesting that personological factors substantially impact moral life.
