ChooseRealFood





The above advert demonstrates a range of persuasive techniques, encouraging individuals to ‘ChooseRealFood’ and to avoid processed, sugary foods. Studies have conveyed this to be an effective way to tackle obesity and provide health benefits for those who follow the ‘low-carb, low-fat’ healthy diet (Meckling, O'Sullivan & Saari, 2004). Primarily, the advert has an adult target audience; individuals who would be providing the food for themselves and others.

Caildini (2009) suggests that one of the strongest influences upon behaviour is the implementation of social compliance and trust in an authority figures. Milgram (1963) demonstrated that subjects could be manipulated or encouraged to follow particular instructions and behaviours when asked by an authority figure. This was further supported by Bickman (1974) who portrayed subjects complied more with an individual dressed in uniform (figure of authority, i.e. a guard), than someone dressed as a civilian. The advert above generates this concept through using the image of two doctors, known specialists and authority figures in the health department. As a result, the audience is more likely to comply with the given message. In addition, the health benefits labelled below the images are more likely to be believed due to the association with the trusted authority figures (Frewer, Howard, Hedderley & Shepherd, 1996).

A merchandising technique, based on the theory of reciprocity, is the use of a free sample (Bawa & Shoemaker, 2004). The theory of reciprocity states that individuals should repay what has been provided or given to us (Cialdini, 2009), violating this rule is viewed as an un-sociable trait. Regan (1971) exhibited this through a confederate providing a small favour for the subject, leading the subject to then agree to a later favour when asked. This demonstrates an external pressure to agree due to the small favour provided previously. The advert provides potential customers with access to the product, through a 'first free meal plan'. However, this free sample can also be interpreted as a gift, of which according to the theory must be reciprocated, leading customers to follow-through with future purchases.


Finally, the advert states that a free sample can be received by simply calling the number provided. Not only does this invite potential customers to receive more information, but it may be suggested they are more likely to follow through with potential orders due to the theory of commitment and consistency. Cialdini, Trost, Newsom (1995) suggest that every individual has a desire to be consistent with their actions and so behave in such ways to justify their decisions, Newcomb (1953) states that for this reason, consistency is a primary motivator of behaviour. According to this theory, a customer would be more likely to commit to the product to appear consistent with their decision to call in the first place and due to the extra time and effort they have gone to in order to receive this information (Cialdini 2009).
