The author, writing on the Typesafe AI blog, says both primitives return probabilities and proposes renaming them \"choice\" and \"scale,\" stating 85% confidence in the explanation. The post follows earlier coverage of Jev and cites a 2021 chart-scale-types reference on nominal and ordinal scales.", "body_md": "One thing that has been tripping me up with [Jev](https://danielmiessler.com/blog/early-thoughts-on-jev) is the difference between [choice](https://docs.typesafe.ai/primitives/choice) and [score](https://docs.typesafe.ai/primitives/score). I keep mixing them up.\n\nI finally took the time to debate it with my digital assistant, and I came up with a better way of describing it to myself, which I will share here.\n\nThey're both actually returning probabilities. So I was like, well, if they're both choices that are scored by probability, why not call them both choice? Or more importantly, why have a score one that's separate from choice, if score is just giving you back probabilities on the options that you gave, just like with choice?\n\nOkay, so score is very similar to choice in many ways, but the main difference is you provide it in order, as a ladder.\n\nSo it's like cold, warm, hot. Or for security: critical, high, medium, low. Or for customer service: about to cancel, super agitated, and so on.\n\nSo between the structure that is being used, the way you phrase the inputs, and the state that you provide, which is the context, the system itself understands all of that and does a better job of ranking them because it understands that it's a scale.\n\nIn the case of choice, you just get probabilities for whatever list you provide, and it could be in any order because it's not [on a scale](https://danielmiessler.com/blog/chart-scale-types).\n\nNominal Scale: Only the selection name matters, not any particular order. Ordinal Scale: Only the order matters, but you can't tell the relative difference between the items.[Chart Scale Types](https://danielmiessler.com/blog/chart-scale-types), 2021\n\nSo in my mind, I'm going to think of these as choice and scale instead of choice and score, because both of them provide scores.\n\nI'm 85% confident that I have this right. If anyone has a better way of explaining it, please let me know.
