There are important real-life, practical applications associated with an increased understanding of the halo effect and its influence on individual perceptions of others. For example, Palmer and Peterson (2012) found that even when participants were informed that the images of physically attractive people represented those of people with little knowledge of political matters, respondents still judged these images as representative of people who were highly politically-skilled, mature and trustworthy. This has important implications on the state of politics, where the success of some politicians or political parties may be more easily or accurately explained as a result of the halo effect, rather than actual political expertise. Therefore, this knowledge could be used to the advantage of some parties when selecting candidates!
