Fuzzy logic is indeed a better formulation. One nit tho: the intermediary values don't mean 'very likely' or 'unsure' in general. They usually represent degrees of truth or degrees of membership. So it's more like '0.9 tall' means 'quite tall', while '0.5 tall' would be interpreted as 'this guy is tall to a degree of 0.5 out of 1'.

They could technically refer to 'very likely' or 'unsure' only if the predicate you're modeling is itself about certainty or belief. For example, you could say "I'm certain about X to degree 0.8 out of 1" meaning you're quite certain about X. But notice that the 0.8 is about your belief, not about X itself.
