Final answer:
This situation represents a cognitive bias known as racial framing, influenced by media portrayals and stereotypes. It is important to challenge our own biases and critically analyze media representations.
Step-by-step explanation:
This situation represents a cognitive bias known as racial framing. Racial framing occurs when individuals hold stereotypical beliefs about a particular racial or ethnic group, even in the face of contradictory evidence. In this case, Joan believes that most drug addicts are Blacks, despite newspaper reports indicating that drug addiction is more common among Whites.
Racial framing is often influenced by media portrayals and stereotypes. News coverage and images in magazines can contribute to the misrepresentation of race and perpetuate racial biases. For example, television news often focuses on African Americans when reporting on welfare, which can create a perception that they are the majority of recipients, even though White people actually outnumber them in total numbers.
It's important to critically analyze media representations and challenge our own biases to ensure a more accurate understanding of social issues.
