We seem to be in this continual 'dance with chance' - we don't understand it, really, probabilities.
We think in terms of certainties, or perceived certainties. But yet we still dance with chance all the time - we buy lotto tickets, gamble etc. If we understood chance/probabilities, things would be different.
This is starting to matter more. As interfaces start to shift and expectations don't, we start to run the risk of falling into a massive expectation gap. We expect precision when we are actually getting an estimate (possibly in precise language). We expect a binary 'yes or no' answer, when we are actually getting a 'maybe' or 'it depends'.
