Simpson's Paradox occurs when an observed association is spurious – reversed after taking into account a
confounding factor. At best, Simpson's Paradox is used
to argue that association is not causation. At worst,
Simpson's Paradox is used to argue that induction is
impossible in observational studies (that all arguments
from association to causation are equally suspect) since
any association could possibly be reversed by some yet
unknown confounding factor
