Final answer:
The term that most likely explains why one person saw the review and the other did not is selective exposure. This refers to individuals seeking out information that confirms their existing beliefs, while avoiding contradictory information.
Step-by-step explanation:
The term that most likely explains why one magazine reader saw the review and the other did not is selective exposure. Selective exposure refers to the tendency of individuals to seek out information that confirms their existing beliefs and attitudes, while avoiding information that contradicts them.
In this scenario, Emily, who purchased an iPhone 4, noticed the review because it pertains to her newly purchased product. On the other hand, Jon, who owns a Samsung Galaxy, did not notice the review as it is not relevant to his own phone. This demonstrates how individuals engage in selective exposure based on their personal interests and preferences.
Overall, selective exposure is a common phenomenon in media consumption, where individuals actively choose to consume information that aligns with their preexisting beliefs, while neglecting opposing viewpoints.
