Newcomb's Paradox

A thought experiment in decision theory

An infallible Oracle has already predicted your choice and prepared two boxes accordingly.

Box A always contains $1,000.
Box B contains $1,000,000 if the Oracle predicted you take only Box B — or $0 if it predicted you take both.

$1,000
Box A
$1,000
?
Box B
$1,000,000 or $0
