; Risk Landmarks
: '''The 2008 Financial Crisis''' → A case study in "Systemic Overconfidence," where experts believed they had "Eliminated" risk through complex math.
: '''Insurance Industry''' → An entire multi-billion dollar industry built on the "Certainty Effect"—people pay more than the "Mathematical Value" of a risk just to have peace of mind.
: '''Skydiving vs. Smoking''' → People often see skydiving as "Extremely Risky" but smoking as "Moderate," even though the lifetime risk of smoking is significantly higher.
: '''The 'Hot Hand' Fallacy''' → The belief in sports that if a player makes three shots in a row, they are "Hot" and more likely to make the next one (Statistics show this is usually just a random streak).
