: '''The 'Kitty Genovese' Murder (1964)''' → The tragic event that "Started" the study of the "Bystander Effect" and led to the creation of the **911 System** in the USA.
: '''Organ Donation 'Opt-Out'''' → (See Article 460). A "Prosocial Design" that saves thousands of lives by making "Helping" the "Default."
: '''Blood Donation''' → Why we don't "Pay" for blood (Article 459). Kindness is a "Social Market" that is "Destroyed" by "Financial Markets."
: '''The 'Warm Glow' Theory''' → The discovery that even "Purely Selfless" acts create a "Reward" in the brain, proving that "Altruism" and "Self-Interest" are "Two sides of the same coin."
