	Heuristics and Biases is the "Study of the Shortcuts"—the investigation of the "Mental Rules of Thumb" (Heuristics) that the "Human Brain" uses to "Make Fast Decisions" and the "Systematic Errors" (Biases) that "Result" from them. While "Logic" (see Article 111) is "Slow," Heuristics are "Fast." From "Anchoring" and "Availability" to "Representativeness" and the "Confirmation Bias," this field explores the "Architecture of Error." It is the science of "Cognitive Economy," explaining why we "Fear" "Sharks" more than "Cars"—and how our "Intuition" "Fails" in a "Complex, Modern World."

{{BloomIntro}}
Heuristics and Biases is the "Study of the Shortcuts"—the investigation of the "Mental Rules of Thumb" (Heuristics) that the "Human Brain" uses to "Make Fast Decisions" and the "Systematic Errors" (Biases) that "Result" from them. While "Logic" (see Article 111) is "Slow," **Heuristics** are "Fast." From "Anchoring" and "Availability" to "Representativeness" and the "Confirmation Bias," this field explores the "Architecture of Error." It is the science of "Cognitive Economy," explaining why we "Fear" "Sharks" more than "Cars"—and how our "Intuition" "Fails" in a "Complex, Modern World."

== Remembering ==
* '''Heuristic''' — A "Mental Shortcut" that allows for "Fast," "Frugal" decision-making (e.g., 'If it's expensive, it must be good').
* '''Cognitive Bias''' — A "Systematic Deviation" from "Rationality" in "Judgment" (A 'Predictable Error').
* '''Anchoring''' — The "Bias" where people "Rely Too Heavily" on the "First Piece of Information" (The 'Anchor') they receive (e.g., 'The first price mentioned in a negotiation').
* '''Availability Heuristic''' — The "Bias" where people "Estimate Probability" based on "How Easily" an "Example" comes to "Mind" (e.g., 'Fearing plane crashes because they are on the news').
* '''Representativeness Heuristic''' — "Judging" the "Likelihood" of an event based on "How Well it Matches" a "Stereotype" (e.g., 'The Linda Problem').
* '''Confirmation Bias''' — The "Tendency" to "Seek Out," "Interpret," and "Remember" information that "Supports" our "Existing Beliefs."
* '''Hindsight Bias''' — The "Tendency" to "Believe" that an event was "Predictable" "After it has Happened" ('I knew it all along').
* '''Overconfidence Bias''' — The "Tendency" to "Overestimate" our "Knowledge," "Ability," and "Precision."
* '''Sunk Cost Fallacy''' — The "Bias" where we "Continue" an "Activity" (like 'Watching a bad movie') because we have already "Invested" "Time or Money" in it.
* '''Dunning-Kruger Effect''' — The "Bias" where "Incompetent People" "Believe they are Experts," while "Experts" "Underestimate" their "Relative Skill."

== Understanding ==
Heuristics and biases are understood through '''Speed''' and '''Mismatch'''.

'''1. The "Efficient" Brain (System 1)''':
Why do we have "Biases" at all?
* (See Article 616). **System 1** is "Always On."
* It must "Make Decisions" in "Milliseconds" to "Keep us Alive."
* **Heuristics** are "Good Enough" for **95% of Life.**
* If you see "Movement" in the "Grass," you don't "Calculate Probability"—you **"Run."**
* "Bias" is the "Price" of **"Speed."**

'''2. The "Modern" Mismatch (Evolution)''':
Why do we fear "The Wrong Things"?
* Our "Brain" evolved in the **"Savanna"** (see Article 571).
* In the Savanna, **"Availability"** (What you saw recently) was a "Great Way" to "Learn about Danger."
* In the **"Modern World"**, "The News" (see Article 542) "Floods" our brain with "Rare Disasters."
* Our "Savanna Brain" thinks these "Rare Events" are "Everywhere."
* We have **"Primitive Software"** running on **"High-Tech Hardware."**

'''3. The "Anchor" of the Mind (Comparison)''':
The "Relativity" of Value.
* If a "Shirt" costs **$100**, you think it's "Expensive."
* If you see a **$500** shirt first, and then the **$100** shirt is "On Sale," you think it's a **"Bargain."**
* The "Brain" is **"Terrible"** at "Absolute Measurement" but **"Great"** at "Comparison."
* "Marketers" use this "Anchor" to "Control" your "Perception of Value."

'''The 'Linda Problem' ''': A classic experiment. "Linda is 31, outspoken, and concerned with social justice." People were asked if it's more likely that: (A) Linda is a Bank Teller, or (B) Linda is a Bank Teller **and** active in the Feminist Movement. Most chose (B), even though (A) **must** be more likely (since B is a subset of A). It proved that "Narrative" (Representativeness) "Trumps" "Math" in the human mind.

== Applying ==
'''Modeling 'The Anchoring Effect' (Predicting 'Valuation'):'''
<syntaxhighlight lang="python">
def estimate_value_with_anchor(true_value, anchor_value, susceptibility_pct):
"""
Shows how 'Irrelevant Numbers' pull our estimates.
"""
# Estimate is pulled toward the anchor
pull_strength = susceptibility_pct / 100
estimated_value = true_value + (anchor_value - true_value) * pull_strength

error = abs(estimated_value - true_value)
return f"ESTIMATED VALUE: ${round(estimated_value, 2)}. (Error due to Anchor: ${round(error, 2)})."

# Case: Estimating the price of a house ($500k) after seeing a 'High Anchor' ($800k)
print(estimate_value_with_anchor(500000, 800000, 30))
</syntaxhighlight>

; Heuristic Landmarks
: '''The 'Availability' of Fear''' → Why people are "Afraid of Sharks" (1 death/year) but not "Ladders" (300 deaths/year): because "Sharks" make for "Better Movies."
: '''The 'Halo Effect' ''' → The "Bias" where we "Assume" that because someone is "Good-looking" or "Famous," they are also "Smart" or "Kind."
: '''Self-Serving Bias''' → The "Tendency" to "Take Credit" for "Success" but "Blame the Environment" for "Failure."
: '''The 'Planning Fallacy' ''' → The "Bias" where we "Underestimate" "How Long" a task will take (e.g. 'Every construction project ever').

'''The Concept of "De-biasing"''': Analyzing "The Cure." Can we "Stop" being biased? Research shows that **"Knowing"** about a bias "Hardly Helps." You cannot "Turn Off" System 1. The only "Cure" is **"Checklists"** and **"External Systems"** (see Article 602) that "Force" you to use **"System 2."** "Don't trust your brain; trust your process."

== Evaluating ==
Evaluating Heuristics and Biases:
# '''Rationality''': Is "Bias" "Truly Irrational"? (Is it 'Rational' to 'Save Time' even if you make 'Small Errors'?).
# '''Justice''': (See Article 560). How do "Heuristics" lead to "Stereotyping" and "Systemic Racism"?
# '''Politics''': How does "Confirmation Bias" create "Echo Chambers" (see Article 542) and "Polarization"?
# '''Impact''': Why do "Doctors" and "Judges" make "Predictable Errors" based on the "Time of Day"? (The 'Noise' problem).

== Creating ==
Future Frontiers:
# '''The 'Bias-Correction' HUD''': AR glasses that "Highlight" "Anchors" and "Confirmation Bias" in "Real-Time" during a "Meeting."
# '''Personal 'Logic' AI-Partner''': (See Article 08). An AI that "Monitors your Thoughts" and "Interrupts" when you are "Falling" for a "Heuristic."
# '''Global 'Evidence' Markets''': A "Platform" that "Rewards" people for "Finding Information" that **"Contradicts"** their "Beliefs," "Fighting" "Confirmation Bias."
# '''Automated 'Hindsight' Log''': A "Digital Journal" that "Records" your "Actual Predictions" before an event, "Preventing" your "Brain" from "Rewriting History" after.
