Altruism seems to be built into our DNA. From the founding of thousands of public libraries by Andrew Carnegie a century ago, the recent mass emergence of social entrepreneurs, and the dawn of the “effective altruism” movement, “making a difference” is part of what gives us purpose. Yet not all altruism is created equal. In labs around the world, studies are being conducted to better understand why we give, what we can learn from our mistakes, and how we can use evidence-based methods to more effectively help our fellow man.
