Questions: Evelyn is a hard worker and has a good job and a modest, but nice house. However, Evelyn checks her social media accounts regularly, and follows several celebrities. When she sees them getting facials with real gold and buying expensive cars and houses, she thinks about her own belongings and feels inadequate. This illustrates: downward social comparison upward social comparison class-based bias self-serving bias

The answer is upward social comparison.

Downward social comparison occurs when individuals compare themselves to others who are worse off or less successful. This often serves to boost their own self-esteem. In this scenario, Evelyn is not comparing herself to people who are less successful or have fewer possessions.

Upward social comparison happens when individuals compare themselves to others who are better off or more successful. This can lead to feelings of inadequacy or inspiration, depending on the context. Evelyn is comparing herself to celebrities who have more luxurious lifestyles, which makes her feel inadequate about her own belongings.

Class-based bias refers to prejudices or assumptions made based on someone's social class. This scenario does not specifically illustrate class-based bias, as it focuses more on Evelyn's feelings of inadequacy rather than any bias she might hold.

Self-serving bias is the tendency to attribute positive outcomes to oneself and negative outcomes to external factors. This scenario does not illustrate self-serving bias, as Evelyn is not attributing her feelings of inadequacy to external factors but rather to her own comparisons with celebrities.
