Internet-Metaphors are plenty in this one: Eating Popcorn in Front of a Mirror May Induce Some People to Eat More Popcorn.
Food tastes better and people eat more of it when eaten with company than alone. Although several explanations have been proposed for this social facilitation of eating, they share the basic assumption that this phenomenon is achieved by the existence of co-eating others. Here, we demonstrate a similar “social” facilitation of eating in the absence of other individuals.
Elderly participants tasted a piece of popcorn alone while in front of a mirror (which reflects the participant themselves eating popcorn) or in front of a wall-reflecting monitor, and were found to eat more popcorn and rate it better tasting in the self-reflecting condition than in the monitor condition.
In Internet-Terminology: „Participants tasted a piece of internet-outrage while on the web (which reflects the participant raging) or alone, and were found to rage more and rate it more arousing in the self-reflecting condition than in the alone condition.“
