    Evolution happens even without any selection pressures, for example with genetic drift.

    Another important factor is whether the place is monetizable. Places where you can't make money are less likely to be infested with AI.

    The probability is exactly zero by definition. The maximum score on a test is a raw score of 100%. Tests are normalized to have the reported scores fit a normal distribution. An ou…

    You seem to be under the mistaken belief that democracy means deciding policy based on opinion polls. This is not how democracies work in practice, and opinion polls often show tha…

    It's possible to do proportional representation with a ranked choice voting system where you vote for individuals rather than parties. Or you could allow voters to rank either part…

    I don't think national elections need to have districts smaller than a state at all. If all of a state's seats in the House that are up for election were decided in a single state-…

    "120" and "0.12%" both have 2 significant digits. "120." and "0.120%" have 3 significant digits.

    I don't think it's quite correct to call it a regressive tax. Driving a car in Manhattan is a luxury, so this is a tax on a luxury that subsidizes transportation that works for eve…

    Protests don't need to change the minds of the public to work. For example, protests still work in non-democratic societies in which public opinion has no bearing on policy. They w…

    For those who believe that billionaires are a policy failure, the answer is they should be taxed more to the point that there are no more billionaires.

    If you want to know whether a drug is more effective than placebo, the answer to that question depends on both the data collected in a study and the initial study design. There’s a…

    Note that as a plane burns fuel, its maximum sustainable altitude and its most fuel-efficient altitude both increase. This explains why the pilots did not climb to a higher flight …

    A union B is defined as the set of things that are in A or in B; A intersect B is defined as the set of things that are in A and in B. So I don't really see it as an arbitrary choi…

    You can interpret 0 and 1 as probabilities. 1 + 1 = 1 in this case makes sense because P(A or B) = P(A) + P(B) - P(A and B). You can interpret "A or B" as a set union and "A and B"…

    It sounds like you are describing a multidimensional array, which can be used to represent a tensor, but is not conceptually the same thing. A tensor is an element of a tensor prod…
