Show morePrevious research has shown that gruesome evidence influences guilt decisions. Several scholars have put forward that the emotional response to gruesome evidence drives this effect. The current systematic review aims to critically scrutinize the current literature on this underlying emotion mechanism, by reviewing studies on the potential mediating role of emotion.
