Chapter 13: Judgment, Decisions, and Reasoning Flashcards
Judge, Reason, & Decide: The Relationship
- All 3 are different, but they are interconnected
- You need judgements to reason about, and then reasons to make decisions
Inductive Reasoning
- The process of drawing general conclusions based on specific observations and evidence
- I usually get hard when my bros grab my weiner–I might be gay!
The Availability Heuristic
- Events that come to mind fast are more likely to occur
- Shark attax
The Availability Heuristic: Illusory Correlations
- Occurs when a relationship between 2 thangs seems to exist, but in reality shit isn’t related at all!
- Related to da availability heuristic bcuz we think their race is correlated with their smell
The Representativeness Heuristic
- We often judge people or situations based on how much they represent a larger group
- i.e., dude has glasses, he gotta be a fuckin nerd ass!
Representativeness Heuristic: The Base Rate
- The relative proportion of different classes in the population
- Even though there’s way more farmers than librarians, people think a quiet guy with glasses is more likely to be a librarian
The Representativeness Heuristic: The Conjunction Rule
- The probability of 2 events (A & B occuring together) cannot be higher than either one happening on its own
- People think its more likely that I’m racist and have a small cock than that I’m just racist! And its only based on my facebook!
Representativeness Heuristic: The Law of Large Numbaz
- The larger the # of individuals randomly drawn from a pop, the more representative it’ll be of the ovrall pop
- If you take a group of 20 vs 2000, you’re less likely to get an accurate vision of how many Asians there are
Attitudes & Judgment: The Myside Bias
- People tend to evaluate evidence in a way that’s biased to their own opinions
- I might think arguments against cigarette smoking are gay and stupid and biased!
Evaluating False Evidence: The Backfire Effect
- People might actually support their viewpoint MORE after being presented wit contradictory evidence
- When someone shows me how easy cigarettes kill your lungs, I will chastise them and be more into ciggys!
Deductive Reasoning
- We determine whether a conclusion logically follows from statements
- All men are born with cock
- I am a man
- A am born with cock
Deductive Reasoning: Syllogisms
- Consist of 2 broad statements (premises) which are followed by a conclusion based on the premises
- All cops are bastards
- You are a cop
- You are a bastard
Deductive Reasoning: Categorical Syllogisms
- The premises & conclusions all start with ALL, NO, or SOME
- All cops are bastards
- All white men are cops
- All white men are bastards
Deductive Reasoning: Validity
- Not so much about truth of the conclusion, but about the way the way the argument is presented
- All men are gay
- I am a man
- I am gay
- Valid arg but NOT TRUE
Deductive Reasoning: Belief Bias
- The tendency to think a syllogism is valid if its conclusion is believable
- The argument might be technically flawed, but if the concluge is believable, we might mistake it for a good one
Deductive Reasoning: The Mental Model Approach
- Mental Models are specific situations in the mind that help determine the validity of syllogisms in deductive reasoning
- These save us from knowing the rules of logic and using abstractions to figure shit out
Conditional Reasoning: Conditional Syllogysms
- 2 premises and a concluge, just like categorical syllos
- BUT they contain a conditional aspect (if, then)
- If I ate her out, then she would eat my ass
- I ate her out, therefore, she will eat my ass
Conditional Reasoning: The Watson Four-Card Problem
- Presents an ‘if-then’ reasoning task
- Performance improves when the task is stated in real-world terms
- Shows that people are better at conditional reasoning when they’re more familiar wif da conditions!
Watson Four-Card Prob: The Falsification Principle
- To test a rule, you gotta find situations that would falsify the rule
- You can find a bunch of situations to confirm a condition, but only 1 that falsifies and you’re bunked!
Watson Four-Card Prob: Permission Schema
- A type of condition where IF you meet a certain criteria (19) THEN you get to get rinsed!
Decision Making: Expected Utility Theory
- Assumes humans are generally rational
- Posits that when presented with all relevant info, people will act with maximum utility (goal-oriented)
- Often not the case in practice (peeps are emotional n shit)
Emotions & Decision Making: Expected Emotions
- Emotions people predict they will feel for a particular outcome
- People often use these to weigh their decisions
- How will I feel if I take the risk and ask her to go on a sex date and she says no vs says yes?
Emotions & Decision Making: Risk Aversion
- We tend to avoid taking risks in general because we overestimate the pain of negative feelings
- Even if they could win $200 and only lose $100, many people don’t take the risk because of the possibility of losing unnecessarily
Emotions & Decision Making: Incidental Emotions
- Emotions that are not cause by having to make a decision
- Can be affected my many factors (cake, anal, disposition)
- Even though they ain’t related to a decision, incidental emotions often affect the decisions we make
Judgment & Presentation: Opt-In Procedure
- A decision which requires homie to take an active step to participate
- You gotta leave money on the counter to tip the SubWay employee
Judgment & Presentation: Opt-Out Procedure
- A decision which requires an active step to NOT participate
- You gotta press NO TIP to not tip the SubWay employee
Judgment & Presentation: Status Quo Bias
- We prefer to do nothing when faced with making a decision
- We tend to accept what’s generally offered instead of making an effort to do different shit
- Get an iPhone cuz everyone has one even though its bad for yo ass
Judgment & Presentation: Risk Aversion Strategy
- We tend to avoid risk when the prob is presented as a good certainty vs a bad risk
- Definitely get head VS 50% chance you get sex or nothing
Judgment & Presentation: Risk-Taking Strategy
- We tend to accept risk when the prob is presented as a bad certainty vs a good risk
- Head but Definitely don’t get sex VS 50% chance you get awesome sex!
Decision Making & Brain: Neuroeconomics
- An approach to studying decision making which combines research from psych, neuroscience, & econ
- Shows how brain activashe is related to decisions that involve potench gains or losses
The Dual Systems Approach
- There are 2 mental systems!
- Fast, automatic & intuitive system (SYSTEM 1)
- Slow, more deliberative system (SYSTEM 2)
- Explains why humans can be rational but are often influenced to be irrational when making decisions
