Representativeness Heuristic and Decision Making

The video discusses the representativeness heuristic, a mental shortcut used in decision-making. It explains how people often ignore statistical probabilities, known as base rates, in favor of information that seems representative of a category. Examples include the Tom W scenario, where a description leads to assumptions about his major, and the Linda problem, where people incorrectly assess probabilities based on representativeness rather than actual likelihood.

What is the representativeness heuristic primarily based on?

• Logical reasoning

• Statistical probability

• Personal experience

• Similarity to a prototype

In the duck example, what do people tend to ignore?

• The appearance of the duck

• The statistical probability of encountering a duck

• The sound a duck makes

• The color of the duck

What does the Tom W example illustrate about people's judgment?

• People ignore all descriptions

• People judge based on stereotypes

• People prefer creative descriptions

• People rely on statistical data

In the Tom W example, what is the base rate of engineering majors at his school?

• 5%

• 50%

• 25%

• 70%

What does the Linda problem demonstrate about people's probability assessments?

• People accurately assess probabilities

• People overestimate the likelihood of conjunctions

• People ignore descriptions

• People rely solely on statistical data

In the Linda problem, what is the common mistake people make?

• Assuming Linda is more likely to be both a bank teller and a feminist

• Assuming Linda is only a feminist

• Assuming Linda is neither a bank teller nor a feminist

• Assuming Linda is only a bank teller

What does the conclusion emphasize about the representativeness heuristic?

• It leads to ignoring actual probabilities

• It is based on accurate statistical analysis

• It is rarely used in decision making

• It is the most reliable heuristic

Why do people often rely on the representativeness heuristic?

• It is a logical approach

• It is easier than calculating probabilities

• It is based on personal experience

• It is always accurate

What is a key characteristic of the representativeness heuristic?

• It ignores all descriptions

• It considers all possible outcomes

• It focuses on statistical data

• It matches descriptions to schemas

How does the representativeness heuristic affect decision making?

• It improves accuracy

• It eliminates biases

• It leads to over-reliance on stereotypes

• It is based on thorough analysis
