"Cultists. They’re like cockroaches. We humans are incredibly fine-tuned by evolution for the task of spotting coincidences and causal connections. It’s a very useful talent that dates back to the bad old days on the savannah . But once we developed advanced lion countermeasures like stone axes and language, it turned into our secret curse.

“People didn’t always follow their best interests. Human beings were distressingly bad at risk analysis, lousy with hidden motivations and neuroses, anything but the clean rational actors that economists or diplomats wanted so desperately to believe in, and diplomats had to go by capabilities, not intentions.”
