That reminds me of this great video (http://http://www.vox.com/2015/12/1/...m-mansplainers) about a famous math problem that most people have a natural inclination to guess wrong on. Even when the correct answer was explained to people only a few more changed their minds, but that number grew significantly when they were encouraged to conduct their own experiments on it.

I'm a firm believer that presenting people with well-documented facts and opportunities to do more research can influence public opinion. Growing up in this culture, I used to unquestioningly wear helmets, just because that seemed like the right thing to do. When my husband stopped wearing one at work a few years ago, I was concerned. Looking at facts helped me understand how helmets actually function, how they're useful and when, how they're made, what they'll actually protect against, how laws and peer pressure to wear them affect people, and more effective ways to make cycling safer among many other things. People need information to make informed decisions. There is no single correct answer. Without information, people tend to make irrational choices based on their unexamined feelings or what has become basically folklore.

Ride smart!
