I found a fascinating chart that explores the relationship of emotions and their ability to create a response in a viewer who then “desires” to share a video.
Dr. Karen Nelson-Field, a senior research associate at the Ehrenberg-Bass Institute for Marketing found that videos that communicated exhilaration is most likely to trigger others to share it. This was followed by hilarity. The emotion of exhilaration actually helps a viewer remember a video (65%) Hilarity was 51%.
She concluded that videos which cause strong emotions (positive or negative), are twice as likely to be shared as are weak emotions. Also, a video which communicates personal triumph has a better chance of being shared.
So, when it comes to getting the best response from a viewer, be positive, exhilarate with humor.
