I am an Assistant Professor of Marketing at New York University. Recently, I have been researching how to motivate and facilitate effective altruism and pro-social behavior. How can marketers help people to do the most good possible, be it by donating money, consuming responsibly, campaigning for change, or choosing a career?
More generally, I explore the mistakes that people make in the face of uncertainty, with implications both for marketers and for consumers' ability to meet their goals. In 2019, my work on decision making won the Society for Judgment and Decision Making's Hillel Einhorn New Investigator Award. Yet, I am still the least cited "Joshua Lewis" on Google Scholar.
Outside of research, I am proudly involved with two excellent non-profits as a trustee for the Tabora League for Children (who provide for vulnerable children in Tanzania) and as a member of the advisory board of The Life You Can Save (who promote some of the world's most effective charities). I have also taken the Giving What We Can Pledge, a commitment to give "at least 10% of your income to the organizations that you think can do the most good with it." For what it's worth, my best guess for the organization that can "do the most good" with your money is the Effective Altruism Meta-Fund. But, if you think your money would be better off in my research budget, go ahead.
A list of my papers is below, and you can read more about some of my projects here.
