This is how easy it is to manipulate public perception

The video explores various cognitive biases, including graph theory's application to sexual partners, Berkson's paradox, survivorship bias, Bayes' theorem, availability heuristic, and confirmation bias. It highlights how these biases affect our perceptions and assumptions, often leading to misinformed judgments. The video emphasizes the importance of understanding these biases to make more accurate predictions and decisions.

What mathematical concept is used to explain the average number of sexual partners between men and women?

• Probability Theory

• Graph Theory

• Set Theory

• Number Theory

What is Berkson's paradox primarily concerned with?

• The relationship between attractiveness and personality

• The correlation between SAT and GPA scores

• The impact of selection bias on perceived trends

• The effect of sample size on statistical significance

What is survivorship bias?

• Underestimating the impact of common events

• Overestimating the probability of rare events

• Assuming all outcomes are equally likely

• Focusing on successful outcomes while ignoring failures

What does Bayes' theorem help us do?

• Identify the mode of a distribution

• Predict the median of a distribution

• Determine the average of a data set

• Calculate the probability of future events based on past data

How do people generally perform when predicting outcomes for normal distributions?

• They perform poorly due to lack of information

• They perform well because they are familiar with the data

• They perform inconsistently due to biases

• They perform better with power-law distributions

What is the availability heuristic?

• A method for calculating averages

• A strategy for making decisions based on data

• A mental shortcut based on immediate examples

• A technique for improving memory recall

How does media exposure affect our perception of reality?

• It provides a balanced view of common events

• It minimizes the impact of rare events

• It often overrepresents uncommon events

• It accurately reflects statistical data

What is confirmation bias?

• The tendency to seek out information that challenges our beliefs

• The tendency to rely solely on statistical data

• The tendency to ignore all information

• The tendency to interpret information in a way that confirms our beliefs

In the study on the death penalty, how did participants react to information that contradicted their beliefs?

• They accepted it without question

• They rated it as high quality

• They showed skepticism and questioned the details

• They ignored it completely

What effect does confirmation bias have on people's opinions?

• It makes them more skeptical of all information

• It has no effect

• It polarizes their opinions

• It makes them more open-minded
