I think it&#x27;s a function of both plowing through textbooks and then just googling for information when you need to find something again. It wasn&#x27;t so much that they didn&#x27;t know how to use an index, just that they hadn&#x27;t done it since probably middle school or earlier and had simply forgotten what those 30-40 pages in the backs of reference books were for.
