Well, almost. It is the job of educators to make complicated material as straightforward and easy to understand as possible, but no more. Some things are just plain hard. Additionally, educators must concern themselves with what works for the majority of their students, and have to accept that they won't be able to make things clear for everyone. There comes a point of diminishing returns in simplification and ultimately it is the responsibility of the student to fill in the gaps.
>If it can't be done that way YET, then people with more imagination than you will figure out how to do it. All I ask is that you don't stand in their way, or denigrate them as they accomplish what you cannot imagine.
And in return I ask that you recognize that educators are doing their damndest to teach material that they have spent a lifetime gathering and that expecting them to have a magic bullet is unreasonable in the extreme.
>Two text analysis tools were used to examine the crime narratives of 14 psychopathic and 38 non-psychopathic homicide offenders
The abstract indicates that the study only looked at homicide offenders, and compared them only to other homicide offenders, not to any non-homicide offenders. They also only looked at a total of 52 people which doesn't seem like enough to me. There are so many factors which can change an individual's speech patters that claiming that the findings mean anything at all is irresponsible.
Take this study with a statistically significant grain of salt.
As has been pointed out elsewhere in this thread, if municipalities were really interested in accident reduction, they would increase the length of yellow lights before they installed red light cameras. I won't argue that careless people cause accidents that is self evident, but there is no reason that we should actively increase the chances of putting people in a situation where carelessness leads to an accident.
As for whiplash, you DO in fact get whiplash when hit from behind. A good, properly adjusted (most are not) headrest will decrease the chances of whiplash, but they are not eliminated. In fact, some studies http://www.ncbi.nlm.nih.gov/pubmed/15667814 have shown that firm headrests will INCREASE the chance of whiplash, not decrease it.
But you've entirely sidestepped the point of my original post. A question like "So which is better, a rear-end collision outside the intersection, or a broadside collision inside the intersection?" alone is pointless. You can't consider the question without looking at more data.
