Spatial disorientation has killed many before, such as JFK's brother, and will kill many in the future. When I did my instrument flight rating (IFR) it took a bit of training to get used to trusting my instruments (ESPECIALLY my attitude indicator/artificial horizon) over my own body's senses. We get a little bit of training on this in basic Private Pilot training, but it's more to pass the flight test item and in my opinion it's not enough to properly save someone who enters unexpected weather or flies beyond sunset into the night (without their night rating) until they get their IFR rating.
