Doesn't this make it an intractable problem though? Attribute X is more common in group Y first require a population based study, which can be tampered left and right and doesn't always stay the same over time. (commonality of the attribute can shift with generations) Besides if the goal is "make an algorithm that only base its judgment on population studies" all human decision making algorithms will be the same, and you can endlessly cry wolf.
