Idea in Brief

The Challenge

Systematic cognitive barriers can blind us to our own unethical behaviors and decisions, hampering our ability to maximize the value we create in the world.

The Solution

We have both an intuitive system for ethical decision-making and a more deliberative one; relying on the former leads to less-ethical choices. We need to consciously engage the latter.

In Practice

To make more-ethical decisions, compare options rather than evaluate them singly; disregard how decisions would affect you personally; make trade-offs that create more value for all parties in negotiations; and allocate time wisely.

Autonomous vehicles will soon take over the road. This new technology will save lives by reducing driver error, yet accidents will still happen. The cars’ computers will have to make difficult decisions: When a crash is unavoidable, should the car save its single occupant or five pedestrians? Should the car prioritize saving older people or younger people? What about a pregnant woman—should she count as two people? Automobile manufacturers need to reckon with such difficult questions in advance and program their cars to respond accordingly.
