Final answer:
Seeing an individual daily on the elevator is most aligned with the proximity principle, which aids in forming positive impressions. Treating someone based on stereotypes is least likely to lead to a positive impression.
Step-by-step explanation:
The question asks about which scenario is least likely to lead to a positive impression of a person. Based on the information provided, forming relationships often depends on proximity and frequent contact, suggesting that seeing someone regularly, such as daily on an elevator, increases the chances of forming a positive impression through familiarity. Conversely, stereotypes and prejudice, as mentioned in one example, can lead to discrimination and would likely not contribute to a positive impression. Thus, if a person treats another based on stereotypic beliefs, such as thinking a job applicant is incompetent due to their identity, it creates a negative atmosphere and is least likely to lead to a positive impression.
