So they established that language patterns measured by word frequency changed between 2022 and 2024. But did they also analyse frequencies across other 2-year time periods? How much difference is there for a typical word? It looks like they have a per-frequency significance threshold but then analysed all words at once, meaning that random noise would turn up a bunch of “significant” results. Maybe this is addressed in the original paper which is not linked.
