True, and to the list I'd add 'the ability to pay attention to minor details'.
When Cofty ask if it is a fact we have 23 cromosomes then sure, you can find a way to add context to that such that the statement becomes technically false. But if we dont want to delibrately misunderstand each other what the statement mean is quite clearly roughly "with the popular definition of chromosome the median of the number of chromosome pairs observed in humans is 23" (or some such).
Cofty didn't ask about 23 chromosomes: he asked if it was a fact we had 22 (pairs of) cromosomes.
So unless you're actually a rabbit (!), the answer would be NO, as I suspect a human embryo missing a complete pair of autosomes wouldn't be viable as a fetus, and the mother would quickly abort (if it made it that far).

Perhaps you could explain if you think that statement is factually true and if not, why?
SBF already answered, but here goes again, rephrased:
The acceptable answer (aka a FACT) would depend on what level of understanding is needed for the question: do you mean an answer that is proper for (and satisfies) a child? A teen in a high-school biology course? A social science major taking a general biology course to satisfy his gen ed requirements, or a biology major taking a genetics course in his core curricula? Or, perhaps a doctoral-candidate geneticist defending his thesis on Mosaicism before a panel of biology professors?
The factually-correct answer that suffices for one is not necessarily going to work for the others, where if the teen taking a test in high school biology answers "23" is correct and given full credit for the question, "How many pairs of chromosomes do humans have?", it's woefully inaccurate for someone engaged in genetic research on mosaicism, since they know the answer is not so simple; they'd be unable to conduct research if they approached their work with the childish understanding that the answer was all there was to know on the question. There ARE degrees of factuality and correctness, and some answers are more correct than others, driven by the needs.
Some statements are simply factually WRONG, considering the applicability of the statement's meaning and purpose. As Dr Scott points out, it is FACTUALLY-FALSE to say in 2013 that the average human contains 22 pairs of chromosomes, since the source of the error was being unable to see that the smaller chromosomes were actually separate, and advancements in microscopic capabilities has revealed that there actually are 23 pairs, not 22. That is a scientific FACT. Note the disclaimers ('average'), which allow for the many exceptions mentioned above (Down's, Kleinfelters, Turners, mosaics, chimeras, etc).
Heck, anyone who's taken a college-level exam knows you can contest the answer key, and if you make a strong case for why the question was nebulous or misleading, or you can explain the rationale you used to arrive at your incoorect conclusion (or if you're simply arrogant enough to dare to explain to the college professor why his answer key is WRONG, and YOU are right!), then you can at least get partial (if not full) credit or even get the question thrown out and declared as invalid. Outside of groups like the JWs, knowing more on a subject is NOT viewed as a BAD thing, although it does force one to think about the intended purpose of the test, and consider the context in which the question was posed to try and provide the most-useful and suitable answer. Anyone who's taken alot of tests knows to consider the perspective of who's asking the question.
Unfortunately, the variability of knowledge on an internet forum is vast, where we encounter everything from blithering eediots to freakin' genuises. It's impossible to provide one answer that cover the breadth of experience and knowledge without writing a book (!).

This was a very interesting thread. Now we are reduced to arguing over the abstract. This is so very silly. Can't we keep it normal?
Thanks for reinforcing the point that details that are quite basic and concrete (such as the definition of the terms used in science) are another's abstractions, LOL!
SBF and Cofty have long-been butting heads over differing understandings of the word 'fact', when it's clear that SBF is using it more consistently with the scientific definition, whereas Cofty is paradoxically relying on the more-common layperson's (non-scientific) definition. They could've resolved the disagreement themselves, if only each recognized what the source of the misunderstanding was.
Which reminds me of other common errors made by non-scientists when talking about science:
Most generally over-estimate the importance of "facts" to science, while also under-estimating the importance of "theories".
As pointed out in this thread, facts CAN and DO change, so they're not protected status and/or above questioning. Similarly, lay people abuse the word 'theory', using it colloquially as if it means what scientists would refer to as a 'hypothesis' (eg lay-people will say, "Well, that's just a theory...." as if a pejorative).
