Of course I wear a helmet. Just look at the things. Does anyone think you're any safer by NOT wearing a helmet? It's bonkers not to wear one in my opinion.
Well, I'm not convinced it makes a lot of difference and I've researched the point extensively in the past.
While there is some evidence that helmets do help, there's also plenty of evidence that they make little difference to fatalities. They may even increase risk of accidents occurring in the first place (adversely modifying the behaviour of cyclists and other road users) or injuries where they do occur (e.g. increasing rotational forces on impact).
They're most clearly effective when the incident involves a cyclist falling with no other vehicle involved, which is exactly what their design parameters are for, and why they are most appropriate for young and inexperienced cyclists who are most likely to fall - my 5 year old son always wears a helmet on his bike for precisely this reason. Beyond 12mph, the protection they offer is marginal. N.B KE = 1/2 mv2
Certainly in respect of compulsory wearing of helmets, it's highly inconclusive, except that where helmets have been made mandatory, cycle use is shown to decline significantly with all the health implications that has.
Statistically, it's by no means as clear cut as the case for helmet wearing with motorcycles or seat belt wearing in cars. Actually, if we were looking for the greatest reduction of injuries, it would be far more effective to require pedestrians and car occupants to wear cycle helmets, as they suffer far greater numbers of head injuries that these helmets are designed to protect against.
By far the best protection is to ride well, IMO. Stay legal, anticipate hazards and mitigate them before they become threats. I've come a cropper once in 30 years and the driver involved was banned. I survived with a sprained ankle, though my bike was trashed.
FWIW, I do wear a helmet when commuting, mostly to keep the (non-cyclist) other half happy.
