This is an interesting study on how Turkers can create messages that can be highly motivating to others.
“We found that crowdsourcing is an effective method to design motivational messages. Our results indicate that different messages are perceived as motivating depending on the stage of behavior change a person is in. However, while motivational messages related to later stages of change were perceived as motivational for those stages, the motivational messages related to earlier stages of change were not. This indicates that a person’s stage of change may not be the (only) key factor that determines behavior change. More individual factors need to be considered to design effective motivational technology.”
