Research Projects
​
In the Developing Moral Values Lab, we aim to discover how morality is shaped during childhood and into adulthood.​
Our moral values define us, unite us, and give meaning to our lives. Gaining a scientific understanding of how these values are acquired provides a powerful vantage point from which to make informed decisions about how to facilitate a better future. In order to contribute to this emerging understanding of the inner workings of our moral minds, the Developing Moral Values Lab conducts a range of studies with and adults and with children between the ages of 5 and 10. Some of the issues we are currently investigating include:​
​
-
VARIATIONS IN THE BOUNDARIES OF MORAL CONCERN
How and why do children and adults differ in their beliefs about which entities deserve moral consideration?
​
-
INTELLECTUAL HUMILITY AND RECEPTIVITY TO TESTIMONY
How does an awareness of the fallibility of one's knowledge relate to patterns of selective trust?
​
-
Evaluations of belief change
Is it considered good to change your mind in light of compelling evidence, even in intergroup contexts?
​
-
Assessments of moral character
What does it take to consider somebody else as a good person, and what happens if they temporarily lapse?​
​
-
the roots of environmental ethics
Why do some people care deeply about the planet, while others believe that humans can exploit nature?
