You’re at least the seventh YEC to take that line with me, and I’m sorry but it’s nonsense.
There is nothing whatsoever about that passage that indicates that it only applies to some contexts but not others. It comes from a chapter of Deuteronomy that contains a variety of different laws with no particular overarching theme other than one’s general conduct in society. Besides, even if it was intended to apply primarily to cheating people in transactions, to exclude it from other contexts is to demand the right to tell lies in those contexts. It is also, in effect, to admit that you are wrong.
In any case, those verses are especially important in science, because the sciences, both operational and historical, are all about what accurate and honest weights and measures look like in different contexts in the first place.
You YECs insist that it’s ungracious and divisive to accuse you of lying. I’m sorry, but all I can say to that is if you don’t want to be accused of lying, don’t tell lies.
