If there is a WW3, what longitude will it start in?

The period between 1945 and the present day has been peaceful, with no major wars between great powers. Some have argued that this degree of prolonged absence of conflict is nothing special historically speaking and may end soon, while others have argued this moment of calm will likely last for some time due to the deterrence effect of nuclear weapons, the unipolarity of U.S hegemony, globalisation and international trade, and the efforts of peacekeepers such as the United Nations.

At the time of writing, the Metaculus community has estimated the likelihood of a 'WW3' to be 10%.

The question asks: If there is a "Third World War", what longitude will it start in?

Longitude will be represented on a scale of -180 to 180, with -180 representing 180°W and 180 representing 180°E. A latitude and longitude calculator can be accessed here. A static map can be accessed here.

Many wars are precipitated by regionally-confined international incidents resulting in a clear chain of events producing wider-scale conflict. The answer will be determined by either the longitude of the location of the incident precipitating a WW3 scenario, or the longitude of the region where the first direct confrontation takes place with as much specificity as possible. If the incident/confrontation is geographically long-range in nature (e.g the launch of an ICBM from North Korea to New York), the starting location will be used. If no such location can be identified with the consensus of three moderators, either two years into or following a WW3 scenario, the answer will resolve as ambiguous.

Likewise, the question will resolve as ambiguous if the following conditions for a "Third World War" are not met by the resolve date:

  • Consensus that a state of war exists between at least five G20 member-states, spread out over at least five continents (North America, South America, Europe, Africa, Asia, and/or Australasia)

  • Conflicts between these states has resulted in an excess of ten million deaths and/or damage amounting to 40% or more of global GDP at its level when the first hostilities began.

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.

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.
