Will more than one entrant achieve a perfect score in the 2020 IMO in St. Petersburg?

The International Mathematical Olympiad (IMO) is a mathematics competition for pre-university students. It consists of six questions, each scored out of seven. The highest possible score is therefore 42. The problems are extremely difficult, and mean scores are typically less than 15 marks. It is not uncommon for no students to score full marks, or for only one student to do so, though in 1987 twenty-two perfect scores were achieved, meaning that a perfect score was required for a gold medal. In 2020, the 61st IMO is scheduled to be held from July 8 to July 18 in St Petersburg, Russia.

This question asks: Will more than one entrant achieve a perfect score in the 2020 IMO in St. Petersburg?

For a positive resolution, at the 2020 IMO in St. Petersburg, more than one entrant must achieve a score of 42. Resolution will be via credible media reports.

  • If the 2020 IMO is postponed due to the coronavirus pandemic, this question will resolve after the postponed competition is held.

  • If the competition format is changed because of the pandemic (for example, by going online) but the question format is not changed, i.e. 6 questions worth 7 marks each are asked, the question resolves as above.

  • If the 2020 IMO is cancelled, or if the format of the questions is changed, resolution will be ambiguous.

This question is part of the Academy Series, a set of questions designed to be an introduction to forecasting for those who are relatively new and are looking for a new intellectual pursuit this summer.

Metaculus help: Predicting

Predictions are the heart of Metaculus. Predicting is how you contribute to the wisdom of the crowd, and how you earn points and build up your personal Metaculus track record.

The basics of predicting are very simple: move the slider to best match the likelihood of the outcome, and click predict. You can predict as often as you want, and you're encouraged to change your mind when new information becomes available.

The displayed score is split into current points and total points. Current points show how much your prediction is worth now, whereas total points show the combined worth of all of your predictions over the lifetime of the question. The scoring details are available on the FAQ.

Note: this question resolved before its original close time. All of your predictions came after the resolution, so you did not gain (or lose) any points for it.

Note: this question resolved before its original close time. You earned points up until the question resolution, but not afterwards.

Community Stats

Metaculus help: Community Stats

Use the community stats to get a better sense of the community consensus (or lack thereof) for this question. Sometimes people have wildly different ideas about the likely outcomes, and sometimes people are in close agreement. There are even times when the community seems very certain of uncertainty, like when everyone agrees that event is only 50% likely to happen.

When you make a prediction, check the community stats to see where you land. If your prediction is an outlier, might there be something you're overlooking that others have seen? Or do you have special insight that others are lacking? Either way, it might be a good idea to join the discussion in the comments.
