We don’t talk enough about falsifiability.
Specifically, we don’t talk too much about how importance it is to think of things that are important to you in terms of what can prove them wrong.
Falsifiability is a wonderful thing. It works in design, for a start. You think your design will lend players going this way, and all you need to do to see if your design does that is to see if the players don’t.
Falsifisability is great when you’re learning about science! What would prove this theory wrong? Well, then we keep an eye out for that. The Bible tells us that it’s true, but all we need to do to falsify that is to find a single place the Bible isn’t true – and with that, the whole proof collapses. Easy!
Falsifisiability is also good when you’re considering your own behaviour and if you’re being an unreasonable b-hole. Is there anything this other person could do that would change what you think of them? Is there anything that might indicate you weren’t 100% in the right? And if you can find that, how will you handle it?
The darker half of this thought is that the unfalsifiable is the sign of the conspiracy theory. The internet stranger whose every actions are always false and evil, no matter what she does, the political system that resists all negative examples, the personal belief that resists any proof to the contrary? Watch out for those. That is a mental space where some abusive earwigs live.
