Monkey See, Monkey Do(and so do you!)

The information meme above is describing a 'nudge'. A nudge makes it more likely that an individual will make a particular choice, or behave in a particular way, by altering the environment so that automatic cognitive processes are triggered to favor the desired outcome.

An individual's behavior is not always in alignment with their intentions (termed a value-action gap). It is common knowledge that humans are not fully rational beings; that is, people will often do something that is not in their own self-interest, even when they are aware that their actions are not in their best interest. 

For example, when hungry, people who diet often underestimate their ability to lose weight, and their intentions to eat healthy can be temporarily weakened until they are satiated.
