Question 1

Suppose a colleague claims that if the price elasticity of demand for the company's good is inelastic, then raising the price of the good will lead to higher sales. This is example of what type of reasoning?

Accepted Answer

The statement is an example of deductive reasoning, as it is based on the assumption that if the price elasticity of demand is inelastic, then raising the price will lead to higher sales. This is a logical deduction based on the theory of elasticity.

Question 2

In attempting to determine the average starting salary of your university's graduates, you conduct a survey of a recent set of graduates given to you from the gift/donation department of your university. What is wrong with this logic?

Accepted Answer

The sample of graduates given to you by the gift/donation department is likely to be biased towards those who have found successful and high-paying jobs, leading to selection bias. Graduates who are unemployed or underemployed may not have been included in the sample. This can result in an overestimation of the average starting salary for all graduates.

Question 3

All of your friends listen to hard rock music more than any other genre. Consequently, you conclude that hard rock music is the most popular genre in the United States. What is the flaw in your reasoning?

Accepted Answer

The flaw in the reasoning is availability bias, which occurs when someone overestimates the importance or frequency of something based on their own immediate examples or experiences. In this case, the conclusion about hard rock music's popularity in the United States is based solely on the music preferences of a small, personal circle of friends, rather than on broader, more representative data.

Question 4

A baseball player refuses to wash his uniform during a winning streak because he believes leaving it intact is helping his team win. What is wrong with this logic?

Accepted Answer

Predictable-world bias is the incorrect belief that the world is more predictable than it actually is. In this case, the player believes that not washing his uniform will ensure continued success, which is an attempt to impose predictability on a situation that is largely influenced by chance and skill, not superstitions.

Question 5

A poker player refuses to bet on hands with a pair of aces after losing four consecutive hands with a pair of aces. What is wrong with this logic?

Accepted Answer

The poker player is exhibiting predictable-world bias, which is the mistaken belief that future outcomes can be predicted based on past events in situations that are actually random, like poker hands.

Question 6

Using the following question in a survey to elicit the effectiveness of an advertising campaign would suffer from what sort of bias: "Was the primary reason for your purchase of this product the advertising campaign?"

Accepted Answer

This question suffers from confirmation bias because it assumes that the advertising campaign was the primary reason for the purchase and only asks respondents to confirm that assumption. It does not leave room for other factors that may have influenced the purchase decision, leading to a biased result.

Question 7

Which of the following is an example of flawed inductive reasoning due to availability bias?

Accepted Answer

The answer of Which of the following is an example...

Question 8

Which of the following is an example of flawed inductive reasoning due to predictable-world bias?

Accepted Answer

This is an example of flawed inductive reasoning due to predictable-world bias because it assumes that past performance is an accurate predictor of future performance, despite the fact that the market is unpredictable and subject to change. This bias occurs when individuals assume that the world is more predictable than it actually is, leading them to make faulty generalizations based on limited information.

Question 9

Which of the following is not a reason for weak inductive arguments?

Accepted Answer

Statistical bias is not a reason for weak inductive arguments, as it refers to the tendency for statistical data to be skewed or manipulated in a way that affects the validity of an argument. Availability bias, confirmation bias, and predictable-world bias are all examples of cognitive biases that can lead to weak inductive arguments.

Question 10

Believing that all investment funds consistently beat the market because the hedge funds that exist this year all of have beaten the market over the last decade suffers from faulty inductive reasoning because of what type of bias?

Accepted Answer

This is an example of availability bias, where the decision is influenced by information that is more readily available (in this case, the performance of existing hedge funds) rather than all relevant data. This can lead to overestimating the success rate of investment funds because the ones that failed and are no longer around aren't considered.
