The study found that college students sometimes share misinformation on social media, often for non-informational reasons such as to share eye-catching messages or to interact with friends. The study also indicates significant gender and study-level differences in the reasons cited. The findings suggest that coordinated efforts are needed in IL education and in the design of social media applications to curb the spread of misinformation. For the former, the goal should be to not only equip social media users with the ability to recognize misinformation but also to cultivate an aspiration to stop the forwarding of such messages. Better yet, students should be encouraged to challenge misinformation when they encounter it. From a system design perspective, providing features that afford the flagging and rebuttal of misinformation would be helpful. Although it may not be possible to eradicate misinformation on social media completely, proactive IL intervention can help combat uncritical misinformation sharing. In light of the popularity and reach of social media, as well as its collaborative information seeking potential, it would be worthwhile to devote efforts to help students reduce their misinformation sharing.
