Every year, there are numerous predictions of what might happen during the year. Most of those are “unconditional” predictions – they are not contingent on the occurrence of other events. Most predictions of rare or unexpected or unusual events that have dates associated with them will fail to materialize.
Here are my “predictions” for 2021. They are all based on “subjective probabilities” (similar in concept to the Doomsday Clock of the Bulletin of the Atomic Scientists). Since the likelihood (probability) of many of them is highly contingent on the event of global nuclear war (GNW), I present them in three ways: (1) the probability of the event conditional on no global nuclear war (in 2021); (2) the probability of the event conditional on global nuclear war (in 2021); and (3) the unconditional probability of the event (in 2021). The third probability – the unconditional probability – is simply the “weighted average” of the two conditional probabilities, where the weights are the probabilities of the conditioning events (no GNW or GNW). In mathematical notation:
Prob(E) = Prob(E | no GNW) Prob(no GNW) + Prob(E | GNW) Prob(GNW),
where “E” denotes the event. This formula is a version of the “law of iterated expectations” (LIE).
Because the estimated probabilities involve subjective probabilities, some might refer to them as “Bayesian” probabilities. That would not be correct. The probabilities Prob(E) presented in the last column of the below table are unconditional probabilities, whereas Bayesian probabilities are conditional probabilities. The following makes use of the law of iterated expectations, not of Bayes’ Rule. An example of a conditional probability would be “What is the probability of nuclear war in 2021, conditional on Donald Trump’s winning the 2020 presidential election?.”.
In the table, “GNW” stands for “global nuclear war,” “Prob.” stands for “probability” and “cond.” stands for “conditional.” If a probability is very small, it is assigned a value of zero, even though it is positive. The rows of the table are independent.
If you place any faith in my subjective probabilities, then the significant implications of the following table are clear: (1) If you want to survive for another year, pray that global nuclear war does not occur; and (2) If you want to end mass extinction and the destruction of the biosphere, pray for global nuclear war.
If you don’t like my predictions, substitute your own subjective probabilities in the table, recalculate the unconditional probabilities, and see what you get.
Note that my predictions are based solely on consideration of facts and logical reasoning. They are my opinions based on facts, logical deduction, subjective assessments and statistical inference. They have nothing to do with any religious or spiritual views.
