About the TOPIC

Thinking Deliberately: How to use mental models and rules to aid effective decision making

We all have mental models – simple mechanisms of thinking and making decisions that help guide our everyday life. But we often leave these models unexamined. This is a missed opportunity.

Making decisions is a skill that can benefit from deliberate practice. But deliberate practice is hard. It requires us first to actively examine how we make decisions. It also requires us to learn from others with a track record of successful decision making. Finally it requires us to change ourselves and our embedded biases and mental models as we actively seek to improve our approach to decision making.

This session is not a ‘how to’ because that would imply that I know how to make the perfect decision. Instead this will be a tutorial from a fellow student who is actively seeking to improve and an attempt to summarize some of the best thinking on mental models from smart and wise decision makers that have come before us and might assist you in making tough decisions.

Our Founder

I believe that those of us who are privileged enough to be educated, healthy, and part of powerful networks should not be doing easy things. The only way to justify our privilege is to do the hard things that society demands of us — to solve tough problems and create opportunities for others. I launched The Room to bring the most ambitious ‘doers’ together to do these hard things that will change the world. I welcome you to be a part of our story and join this global community as we make history together.
