あなたの認知の村から世界を読み解く | Mark Barcus | TEDxAustin College

人間の脳は約150人の社会的つながりを扱うように進化してきましたが、世界の人口は一世紀で4倍に増えました。話し手のMark Barcusは、この認知の仕組みと現代世界の規模とのずれが、孤独や分断、そして会ったことのない人々との関係の背景にあると主張しています。彼はこの構造を「認知の村」と呼び、それを理解することで自分自身や他者の見方がどう変わるかを語ります。この講演は、地域の有志によって独立して運営されたTEDxAustin Collegeのイベントで行われました。

• 人間の脳は約150人規模の社会集団に適している
• 世界人口は一世紀で4倍になった
• 認知と規模のずれが孤独や分断に関係している可能性がある

The human brain evolved to manage a social world of approximately 150 people. The global population has quadrupled in one century. That mismatch—between our cognitive architecture and the scale of the modern world—is the unnamed structural condition underneath loneliness, polarization, and our strange relationships with people we've never met. Mark calls this our “cognitive village” and his talk will explore how understanding this concept changes how we see ourselves and each other. Mark earned a Bachelor of Arts in Communication and Media Studies from Austin College in 1984, and went on to earn a J.D. from The University of Texas at Austin in 1988. Mark has over 25 years of experience as a judge and senior executive, having served most recently as the Assistant Chief Immigration Judge in Los Angeles. In 2025, Mark founded the executive consulting company Inner Loop Performance Coaching, where he integrates conscious leadership, decision-environment awareness, and the idea of the “cognitive village” to help leaders effectively navigate complexity. This talk was given at a TEDx event using the TED conference format but independently organized by a local community. Learn more at https://www.ted.com/tedx
