Short Answer 
The answer explains false consensus bias, where individuals mistakenly believe their opinions are widely shared, exemplified by Haben’s assumption about her friends’ college choices. This bias can lead to inflated confidence in decisions and impact social relationships, and it is distinguished from other biases like confirmation bias, which seeks supporting information for existing beliefs.
Step 1: Recognize False Consensus Bias
Haben’s belief that her friends share her college choice is an example of false consensus bias. This cognitive bias occurs when individuals think that their opinions and behaviors are more common than they actually are. In Haben’s case, she overestimates the extent to which her friends agree with her decision.
Step 2: Understand the Impact of This Bias
This bias can lead to feelings of reinforced confidence in one’s decisions. Haben may feel that her choice to attend a college far from home is validated by the assumption that others feel the same way. This misperception can affect her relationships and her perception of social acceptance regarding her plans.
Step 3: Differentiate From Other Cognitive Biases
It’s important to contrast false consensus bias with other cognitive biases like confirmation bias. While false consensus bias assumes others share similar views, confirmation bias focuses on seeking information that supports existing beliefs. Being aware of these biases can help individuals better understand their decision-making processes and societal influences.
