PSIKOLOGI KOGNITIF: PENGAMBILAN KEPUTUSAN DAN PENALARAN (1)
Main summary
Key takeaways
Main ideas and concepts conveyed
- Decision-making and reasoning are central to psychology and everyday life.
- The speaker prompts students to recall how many decisions they’ve made that day, arguing that people make many small and large decisions continuously.
- Decisions often feel rational, but cognitive psychology shows they can be irrational.
- Humans frequently believe their choices are the “best” or most rational, yet their thinking can be distorted by bias.
- Bias and heuristics explain why people don’t always decide objectively.
- Fast brain processing helps us function efficiently, but it also makes us vulnerable to systematic judgment errors.
Methodology / frameworks / instruction-like content
1) How the video frames decision-making (stepwise logic)
- Recognize what a decision is
- A decision is described as:
- A choice among multiple possibilities
- Triggered when a person has needs/desires that are not met
- Leading to action/behavior intended to satisfy those needs
- A decision is described as:
- Decision-making goal
- Intuitively, a “good decision” is framed as selecting the best available action.
- Link to problem-solving
- When solving problems:
- Generate alternative strategies
- Choose one strategy believed to be most effective
- When solving problems:
2) Early decision model: Classical decision theory (“economic men/women”)
- Source/assumption basis
- Built largely by economists and earlier philosophers (not psychologists).
- Strong because it supports mathematical models of human behavior.
- Core assumptions (three listed)
- Complete information
- The decision-maker knows all possible choices and all possible outcomes.
- Unlimited sensitivity
- Can distinguish even very small differences between options.
- Completely rational choice
- Chooses the option that maximizes benefit (or value) according to their preference.
- Complete information
- Example used
- Buying a smartphone “objectively” by:
- Comparing aspects (price, specifications, camera, storage, processor, battery, etc.)
- Assigning weights based on importance
- Scoring and selecting the best overall option
- Buying a smartphone “objectively” by:
3) Subjective Expected Utility Theory (psychological additions)
- What changes from classical model
- Decisions depend not only on outside data/facts, but also on:
- How people judge/estimate
- Their feelings about options
- Decisions depend not only on outside data/facts, but also on:
- Basic goal
- Humans aim to:
- Seek what feels enjoyable/pleasant
- Avoid what feels unpleasant
- Humans aim to:
- Positive vs. negative utility
- Positive utility: choices that bring satisfaction/pleasure
- Negative utility: choices that create discomfort/unpleasantness
- Examples for campus organizations
- Students weigh both:
- Positive side: experiences, relationships, opportunities, portfolio, soft skills
- Negative side: time pressure, harder workload, fear of not fitting in
- Students weigh both:
- Subjective utility and subjective probability
- Subjective utility: value of outcomes depends on individual perspective.
- Subjective probability: likelihood depends on someone’s beliefs/estimates (not necessarily objective reality).
- Practical implication
- Even when objective probability differs, what the person believes strongly shapes their decision.
4) Heuristics as mental shortcuts (efficient decision rule)
- Why heuristics are used
- Humans have limited capacity, time, and energy.
- Instead of evaluating everything, people “filter” quickly.
- Heuristic definition
- A shortcut that reduces cognitive load and speeds decisions.
- Risk
- Heuristics can lead to bias, producing inaccurate or unfair judgments.
- Key example scenarios
- Choosing a seminar quickly based on:
- Whether it’s relevant
- Who the speaker is
- Topic fit and schedule
- Certificate/consumption (not all details are analyzed)
- Choosing a seminar quickly based on:
5) Heuristic strategies taught (explicit list)
-
Satisficing (Herbert Simon)
- Bounded rationality
- People don’t always search for the optimal option.
- They search for an option that is “good enough” to meet minimum needs.
- Process described
- Consider options one-by-one
- Stop when an option feels adequate
- When satisficing is appropriate
- Useful for small/simple decisions
- Not recommended for major decisions, such as:
- Choosing a thesis topic
- Choosing a partner
- Internship location
- High-stakes academic choices
- Bounded rationality
-
Aspect-based elimination
- Process described
- When many alternatives exist, select one aspect first (e.g., distance/location)
- Eliminate options that fail that criterion
- Repeat filtering with the next aspect (e.g., price, then other factors)
- Process described
-
Intuition-based probability reasoning
- Rather than calculating mathematically, people use:
- Intuition based on experience and stories
- Includes the idea of:
- Conditional probability (likelihood depends on conditions)
- Example:
- Belief that grades drop after joining an organization (not always true objectively)
- Rather than calculating mathematically, people use:
6) Biases and judgment errors (three main examples)
- Illusory (false) correlation
- Mistakenly believing two things are connected when they aren’t.
- Overconfidence
- Being too sure about knowledge/judgment.
- Example pattern:
- Feeling exams were easy → studying may have been superficial → worse results than expected.
- Hindsight bias (inside bias)
- After outcomes are known, people believe they “already knew” it would happen.
- Example:
- After exam results, “I already predicted the questions would be difficult.”
7) Additional heuristics for probability judgment (listed concepts)
- Representativeness heuristic
- Judging likelihood based on similarity to a mental stereotype/image.
- Also includes the danger of using small samples → premature generalization.
- Availability heuristic
- Estimating frequency/likelihood based on how easily examples come to mind.
- Example:
- Vivid negative stories/events feel like they represent overall reality.
- Anchoring
- The first number/info encountered becomes a reference point that biases later judgments.
- Example:
- First textbook price sets what feels “cheap” later.
8) Framing effect (from decision theory / social psychology)
- Definition
- People react differently depending on how information is presented, not just the content.
- Gain frame vs. loss frame
- Gain frame
- Emphasizes benefits → tends to make people more cautious and risk-averse.
- Loss frame
- Emphasizes losses → tends to make people more willing to take risks to avoid losses.
- Gain frame
- Example used
- Same statistical meaning, different wording:
- “70% manage stress” (more positive tone)
- “30% still at risk” (more negative/threatening tone)
- Same statistical meaning, different wording:
- Application
- In student life, posters, mental health content, and social media can shape engagement and beliefs.
- Students are encouraged to be critical, because framing is not always scientifically accurate.
Lessons emphasized
- People often rely on shortcuts to avoid cognitive overload.
- Fast thinking increases efficiency but also increases error risk (biases).
- Decision models differ:
- Classical theory assumes fully rational, complete reasoning
- Psychological models account for subjective beliefs, feelings, and perceived probabilities
- For psychology students and future researchers
- Avoid drawing broad conclusions from limited personal stories.
- Use research methods and cross-check claims/data from multiple sources.
