Perhaps the [[Wikipedia:No original research]] page needs to be updated
with
examples which make that point that if it really is that simple, someone else will have done the work for you already, and all you need to do is quote them.
Literally speaking, conversion of temperatures from Fahrenheit to Celsius would fall foul of this. And numerous other things: such as conversion of dates out of one calendar system into another, metrication, currency conversion, inverting family relationships from 'nephew' to 'uncle' ...
No, that's a strawman argument. "Deductive reasoning" becomes original research when it is used to build a case against a position presented in an article, not when used to do unit conversions. Now if you were to assert that based on genetics and "simple deductive reasoning" that uncles were more closely related to nephews than aunts were to nieces, that would be original research, and you'd have to find some source which supported it.
