The Legendary Dragon Alephwyr, named Alephwyr, BA

If you want to know whether you live in a simulation or not, just check for bizarre causal relationships between things that match human prejudices but have not even a hypothetical mechanism behind them.

We can't assess the probability of that instinctively though. Where bizarre sequences of events are inherently easy to discern from the inside: extreme statistical irregularities, apparently acausal phenomenon, unfalsifiable models as the only explanation for various interactions

Like, events where you have the expected internal quale but the event itself can only have happened the way it did if you were acting on the basis of something else -> psychoanalytic models of the subconscious being used to explain misaccounts or fabrications of events.
