A minor point, perhaps a nitpick: both biological systems and electronic ones depend on directed diffusion. In our bodies diffusion is often directed by chemical potentials, and in electronics it is directed by electric or vector potentials. It’s the strength of the ‘direction’ versus the strength of the diffusion that makes the difference. (See: https://en.m.wikipedia.org/wiki/Diffusion_current)
Except in superconductors, of course.
You would be deceiving someone regarding the strength of your belief. You know your belief is far weaker than can be supported by your statement, and in our general understanding of language a simple statement like ‘X is happening tonight’ is interpreted as having a strong degree of belief.
If you actually truly disagree with that, then it wouldn’t be deception, it would be miscommunication, but then again I don’t think someone who has trouble assessing approximate Bayesian belief from simple statements would be able to function in society at all.
