I'm not a fan of baseball but the movie Moneyball (2011) screenplay by Aaron Sorkin (@WI_ScreenWr_Sup) Based on the book by Michael Lewis had me loving the world of baseball. The movie is about baseball, and it contains many lessons on leadership. Here are 3.

Lesson 1: Reproduce successes

Billy Beane played by Brad Pitt wants to win a world series and knows he can't out buy the larger teams like the Yankees, so he turns to the numbers.

With the help of Pete Brand played by Jonha Hill, he realizes he needs players who can fill the bases. Instead of buying players, he's buying wins. By buying wins, he can reproduce how star baseball players perform for half the cost.

Lesson 2: Replace Intuition with Data where possible

Intuition comes in handy in many areas of leadership. If you can replace intuition with data, that removes any bias and human error from the system.

@RayDalio has done this with Bridgewater by replacing his intuition of investing into computer code to streamline and augment his decisions.

However, not all intuition can't be replaced by data. Human intuition of gauging others' emotions should remain intuition.

Lesson 3: Develop others into leaders

Billy has one of his senior players act as a leader to coach the younger players.

As @simonsinek says, if your actions inspire others to dream more, learn more, do more and become more, you are a leader.

Billy coaches his players to his "get on base" philosophy and has them think for themselves.
