Like most of the essays Asimov wrote for F&SF, each one in The Relativity of Wrong begins with an autobiographical anecdote which serves to set the mood.
Yet, Asimov says, a child who spells the word "shuger" (or in some other phonetic way) is "less wrong" than one who writes a random sequence of letters.
Furthermore, a child who writes "sucrose" or "C12H22O11" completely disregards the "correct" spelling but shows a degree of knowledge about the real thing under study.
Irritated, the rationalist Asimov put forth his views in his monthly F&SF column, and the result became the title essay of this collection.
