The 31st First Annual
Ig Nobel Ceremony

September 9, 2021

The 31st First Annual Ig Nobel Prize ceremony happened entirely online on Thursday, September 9, 2021, at 6:00 pm (US eastern time). Ten new Ig Nobel prizes were awarded for things that make people LAUGH, then THINK.
Watch a recording of it right here. (Alternatively, watch a recording of the Japanese webstream.) And dip into some of the press reports, which even include an editorial or two.

[VIDEO NOTE: YouTube’s notorious takedown algorithms sometimes block the ceremony recording that lives there. We have so far been unable to find a human at YouTube who can fix that. We recommend that you watch the identical recording on Vimeo (see above). Here (see below) is the YouTube version]

In addition to the usual English-language stream, there was a separate stream in Japanese, on Nico Nico. (There is a special Ig Nobel exhibition in Fukuoka, Japan, from September 9-November 3)

The ceremony itself included these traditional elements:

Normally, we fund the ceremony almost entirely from ticket revenues, plus a few small amounts from generous donors. But in the Covid-19 pandemic years 2020 and 2021 there are no theater tickets, and so no ticket revenues. Our expenses were lower (no theater rental!), but still substantial. If you or your organization would like to help, please donate to the Ig.


In the Ig Informal Lectures, the new winners explain, if they can, what they did and why they did it.

Normally the lectures happen at MIT, two days after the Ig Nobel Prize ceremony. But in this pandemic year, they will happen online only, one at a time, on and on YouTube.
