A study was created to test this assumption in which the patients were trained to throw a bean bag at a target.

Gee's colleagues got the chance to test that assumption within a year.

To test this assumption, participants were asked questions that planted false information about the event.

It was designed to test the assumption that the presence (or potential presence) of police officers in marked cars reduced the likelihood of a crime being committed.

But nobody has tested this assumption, and our anecdotal evidence suggests it has just the opposite effect.
