But don't take my word for it.
OK.

From the hospitalized group interesting associations emerged of naso-ethmoidal fracturing with spectacle wearing and maxillary fracturing with denture wearing. Hospitalized motorcyclists who had worn open-face helmets, or full-face helmets with flexible face-bars, had sustained facial fracturing but minimal brain injury. In contrast, motorcyclists killed from anterior craniofacial impact whilst wearing full-face helmets with rigid face-bars had sustained fatal skull base fracturing in the absence of significant facial trauma"
The above quote is from a "study" by Rodney Cooter, and it has been thoroughly discredited.
Problems with the study/author:
1. It uses a statistically insignificant sample size. Cooter's conclusions are based on autopsies of 11 motorcycle fatalities.
2. Cooter's conclusion, was not that riders should wear open face helmets. Rather, he suggests the real solution is to design full face helmets, with impact absorption qualities in the chin bar. And guess what...he just happens to hold a patent on such a design, that would have benefitted him handsomely if regulatory agencies required such a thing.
3. The study and the helmets involved in Cooter's observations, are now over 20 years old. Helmet safety technology of today, bears little resemblance to what was used back then...the advancements in design and materials technology alone, make Cooter's "study" meaningless.
4. Even back them, nobody at the conference where Cooter's findings were presented agreed with them. His findings were met with ridicule by others with vastly more experience in helmet design and injury studies - in particular, Hugh Hurt, author of the famous Hurt Report which looked at over 900 motorcycle accidents. In rebuffing Cooter's report, Hurt stated he had never seen a fatal motorcycle accident - before or after Cooter's study - where a rider wearing a full face helmet would have survived if wearing an open face.
So, feel free to believe a 20+ year old study, that has been thoroughly debunked. I'll pass...

I don't wear full face rigid helmet's. this is why the hinged full face helmets where developed and used by most police forces.
No...this was done for communications purposes. Cops can't easily talk on radios or converse with the public, with a full face helmet on. Such convenience factors are the primary reason for consumer demand as well - not safety.
That being said, I'm not knocking convertible helmets - there's far less disagreement on their efficacy compared to full face as there is with open face designs. Schuberth in particular, has gone to great lengths to make the hinged design safe and convenient. I actually tried on a few, but couldn't find any that fit my head well.
My disagreements above, are strictly related to open face helmets - which is what the study you referenced was referring to.
