Suppose we have a proposition of any given form (for example, "the earth is 'flat' "). In terms of observations, the best we can do is to decide if the proposition is disproved or not disproved (which is different than "proved"; the latter is, strictly speaking, reserved for mathematical contexts). Now to express "the proposition is not compatible with what is observed" we have an elegant one word "disprove" (or various alternatives); I wonder if there is also a one-word term that can express "the proposition is compatible with what is observed" even to a non-scientific person without compromising precision.
I guess using "support", for instance, in a way such as "the data support the proposition" would confuse some (?); on the other hand, saying "the data disprove the proposition" seems unlikely to mislead. And I am seeking a choice of such a verb that not only precisely conveys "the proposition is not disproved by the data" but admits almost no chance of misleading.
By the way, an empirical situation of the need is when one needs to explain scientific nuances to younger minds.
