4:03Now PlayingLeaders didn’t always wear suits, but they have always been important. In prehistoric times, the leader kept the tribe from brawling over dinner, and in return, they got first crack at the grub. In the millennia since, the dress code has changed, but the expectations have not. We’re willing to cede certain perks to leaders so long as they fulfill their end of the bargain: Step up when it matters and protect the group.
In this video lesson, leadership consultant Simon Sinek explores the evolution of organizational hierarchy and how we can use it to understand the role of leadership today.

About Simon Sinek:
Simon O. Sinek is an author best known for popularizing the concept of "the golden circle" and to "Start With Why," described by TED as "a simple but powerful model for inspirational leadership all starting with a golden circle and the question "Why?"'. He joined the RAND Corporation in 2010 as an adjunct staff member, where he advises on matters of military innovation and planning. His first TEDx Talk on "How Great Leaders Inspire Action" is the 3rd most viewed video on TED.com. His 2009 book on the same subject, Start With Why: How Great Leaders Inspire Everyone to Take Action (2009) delves into what he says is a naturally occurring pattern, grounded in the biology of human decision-making, that explains why we are inspired by some people, leaders, messages and organizations over others.
He has commented for The New York Times, Wall Street Journal, The Washington Post, Houston Chronicle, FastCompany, CMO Magazine, NPR, and BusinessWeek, and is a regular contributor to The Huffington Post, BrandWeek, and IncBizNet.
