Yet there are no existing self-report scales for measuring the process of decision...

Now out in Behavior Research Methods! With @maxmaier.bsky.social & Falk Lieder, we developed the 12-item Decision Process Scale, which measures how much people rely on rules vs. cost-benefit reasoning and intuition vs. deliberation in individual dilemmas.
