Josh May and I are conducting a meta-analysis on judgments related to the Doctrine of Double Effect. In particular, we are interested in seeing if the byproduct/means distinction is reflected in everyday moral judgments. The classic cases that illustrate the byproduct/means distinction are the Bystander and Footbridge cases (respectively). Or course, there are many different variations on these paradigmatic cases that also involve exploring the means/byproduct distinction.

We are currently looking for unpublished studies that you may have that are relevant to this meta-analysis. We would greatly appreciate you sending us descriptive statistics or the raw data so that we could include your unpublished studies in the meta-analysis. We are only interested in unpublished studies that experimentally manipulate the means/byproduct distinction.

Unpublished studies can be crucially important for accurately estimating mean effect sizes, so your help in this endeavor would help the community interested in this distinction.

If you have any unpublished studies, or have questions, please email them to Adam Feltz (adfeltz@mtu.edu). We’ll start compiling the data we receive in two weeks (July 15^{th}). Thanks for your help!
