The reason self defense exists is because of a concern that people will be attacked. And attacked with life changing consequences. The issue is that these attacks are rare and so we get complacent. Like texting and driving we take short cuts that while we get away with. It is still considered a high risk behavior. Self defense has become the equivalent of the comment. "I have been texting and driving for years and never had a problem" This becomes the evidence we use to justify our methods. We then use this justification to teach those methods to others. And it is not grounded in truth. For texting and driving we need to move away from anecdotes and look at the research. For self defense we need to approach it with the same mindset. And look at the research. In self defense results theoretically should matter more than happiness, comfort and feelings. It is more convenient to text and drive. It is more convenient to learn a self defense that doesn't work. But if you are advocating personal safety then you need a method based on truth and a training system based on results.
