Your decisions determine what work you do, how much money you make, who you spend your time with, your health, and ultimately, your happiness. Knowing when to use your intuition is key to decision-making success, but it's not magic -- it's science.

TEDxColumbusCircle (http://www.tedxcolumbuscircle.com) was produced by a team from Manhattan Productions (http://www.manhattanproductions.com), Womenkind (http://www.womenkind.net), Gender Fair (http://www.genderfair.com), and reimagine.world. Spencer is an entrepreneur and mathematician, with a goal of improving human decision making. He founded ClearerThinking.org, which offers free bias and decision making tools used by over 200,000 people, and Spark Wave, a startup foundry which creates novel software products from scratch, designed to solve problems in the world.
