What is the most common outcome of a hazardous situation? For example, not being trained in how to undertake a complex and potentially injurious actvity... not having the proper safety equipment... not paying attention... not being sober while doing the activity... etc.
The most common outcome is: NOTHING. Absolutely nothing.
Which lulls people into a sense of complacency. If the activity were so risky that huge percentages of people died doing something, not many would do that activity. But most people act unsafely in some area of their lives, and routinely get away with it.
Until someday, all of the tumblers of the cosmic lock align, and *bang*, they get bit by probability and they fall victim to the risk factors.
This is why it is so hard to talk to people about safety. They just don't get it. They don't see the big picture, they can't reason using statistics, most of what influences their behavior is via direct experience, word of mouth, peer group pressure, or media influence, and they just go along with all of those.
