So this is the point where you exit from this amazing study and say we just 'know?
How can anything be solved this way. Are you not in favor of the scientific method?
You've claimed a hypothesis. You brought a study to the table. And now you are already making excuses for how the study couldn't capture the absolute truth?
You dont see anything wrong with this?
If this is in fact happening and its happening at a rate greater for blacks as we are all scolded into believing....wouldn't it show up SOMEWHERE in the data?
