Event Details

The largest yearly confab of Mensans anywhere, the American Mensa Annual Gathering started as a small, two-day meet-and-greet at the New York Belmont in 1963. The event now spans five days — six in 2021! — and features a sprawl of talks, games, and entertainment unlike any other.

The 2021 Annual Gathering is a party 75 years in the making! Join Mensans from around the world to celebrate the 75th anniversary of Mensa’s founding. With a focus on cultural and intellectual experiences from around the globe, we aim to showcase all the different kinds of smart. Registration opens Oct. 1.

Colloquium 2021: Advances in Food Science

Before it hits our plates, there’s a lot that goes on behind the scenes with what we eventually eat. The ongoing developments within our food supply are staggering — and that was before the pandemic: gene-edited crops, plant-based proteins, breakthroughs in how we understand nutrition, the consolidation of suppliers, agriculture’s escalating biological arms race, changing climates — it’s enough to make your stomach churn! We will also explore the impact COVID-19 has had on food supplies and safety.

Sponsored by the Mensa Education and Research Foundation, this one-day educational symposium provides a forum for Mensans and the general public to explore, debate and evaluate a major issue of long-range importance to society.
