Do NOT Read This Article: The Effects of Autoclitics and Nudge on Choosing

The use of autoclitics can influence the behavior of individuals making choices when responding to a survey (e.g., checking or unchecking a box). In two studies, we investigated the effects of autoclitics as "nudges" on choice by manipulating different frames (opt-in and opt-out) and default options (i.e., unchecked and checked boxes). Undergraduate students recruited from behavioral science courses engaged with materials in the study. In study 1, we used an online survey at the beginning of the semester offering the choice of whether to enroll in extra-academic activities (i.e., practice tests) available via the online course platform, Blackboard. We randomly assigned students into one of four groups: (1) option to enroll with an unchecked box, (2) option to not enroll with an unchecked box, (3) option to enroll with a checked box, or (4) option to not enroll with a checked box. Results showed that the option to not enroll with an unchecked box produced higher enrollment to receive extra academic activities. In the middle of the semester, we conducted a within-subject arrangement wherein students who initially opted out of receiving activities had the option to accept them following exposure to the negative autoclitic frame. Most of these students opted into receiving activities. In study 2, we replicated the methods of study 1 in Canvas, a different course platform, and obtained similar results. We briefly discuss the implications of a nudge for ethical consent.
