Can large language models stand in for human participants?
Many social scientists seem to think so, and are already using "silicon samples" in research.
One problem: depending on the analytic decisions made, you can basically get these samples to show any effect you want.

Turned out that he was right insofar simply not using GitHub Actions easily fixed the problem.
Told my husband I was struggling with GitHub Actions and he told me to use GitLab instead.
