While listening to the Hubermann Lab podcast with guest Tim Ferriss, the following quote was mentioned:
"Judge a man by his questions rather than his answers."
-Voltaire
Please edit "man/his" to "person/their."
Or don't.

Funny thing: I looked up the quote. It turns out that, according to my brief research, that quote is wrongly attributed to Voltaire and isn't quite correctly stated:
"It is easier to judge the mind of a man by his questions rather than his answers."
-Pierre-Marc-Gaston de Levis (Wikipedia page)
