Bernstein–von Mises theorem

The Bernstein–von Mises theorem is a mathematical statement that tells us something really important about how accurately we can predict the outcome of experiments. It tells us that if we keep repeating the same experiment, and use the information we get from it to make predictions about what will happen in the future, then the predictions we make will get more accurate over time. In other words, the more experiments we do, the better our predictions will be!
