I really don't want this guy's blood and tissues mucking up my
pristine workshop so I thought some nice, gory pictures (and
stories to go with 'em) would be a nice deterrent.
You might want to bear in mind what the Army found out during WWII
in their efforts to get GIs to wear condoms to prevent venereal
First, they made films with graphic images of what advanced VDs do
to genitals, etc, figuring they’d make the point most strongly.
Oddly, use of condoms actually went down. They made a new campaign
using cartoon characters (Mickey Mouse, if memory serves) just
talking about the importance of condoms and why to use them, in an
entertaining way, and condom use went way up.
The psychologists concluded that the graphic images were too
horrible to think about and got associated with condoms in the guys’
minds so they didn’t want to think about condoms either. A more
moderate approach was less threatening and more effective.
Food for thought.
P.S. I have tried, a few times, to prominently display a bur or bit
with hair wound around it, when such an incident occurred, as a
warning for students where I teach. Every time, the display vanished
pretty much instantly. Evidently, no one was willing to look at even
a few ripped-out hairs.
