Are two heads really better than one?

On February 21, 2020 I had blogged about a Savage Chickens cartoon in a post titled Let a Freakbot take care of your anxiety about public speaking. Today Doug Savage had another cartoon (shown above) titled Time for an Upgrade. Note that those two screams are slightly different: ‘Aaaaauugh’ and “Aaauugh.’

According to Bartlett’s Familiar Quotations and The Yale Book of Quotations the sentence “Two heads are better than one.” is attributed to John Heywood in a 1546 book, Dialogue of Proverbs. In a piece On the Reading of Old Books C. S. Lewis had a longer version:

“Two heads are better than one, not because either is infallible, but because they are unlikely to go wrong in the same direction.”
