This kind of nonsense is what you get when too many journalists have too little training in science and the scientific method.

You know, the part where you grasp what a "control" is.

Too many journalists think it is somehow a scientifically compelling study when they stick up a notice that says "please email me if you are a Muslim and faced a rude border guard at the US border since Trump was elected" or "please email me if you have been turned away from the US border since Trump was elected".

And their control? Insert here sound of crickets chirping...
