Another benefit to thinking in probabilities is that you don’t get as attached to ideas. You don’t feel the need to defend your Opinion past it’s expiration date. People can have better discussions without getting offended.
Otoh probabilities are hard to check for correctnessso you can weaael out of being wrong by making everything you say a motte-bailey deception (to use a slatestarcodex term).
That's why it's important to be precise in describing what you mean (which may involve explaining the intended meaning when using a common word), so that you can't back-track on it later. Conversely, when you see someone not doing that, be prepared for the possibility of weaseling out.
