You don't believe data

N. passed along this passage from a book she’s reading, The Water Knife, which from the way she’s described it, is clearly a book I’ll be reading when she’s done:

“This was never about believing…This was about looking and seeing. Pure data. You don’t believe data–you test data.” He grimaced.”If I could put my finger on the moment we genuinely fucked ourselves, it was the moment we decided that data was something you could use words like believe or disbelieve around.”
The Water Knife by Paolo Bacigalupi. 2015
