The world is full of potential hazards. Unfortunately, the things that we’re afraid of oftentimes aren’t the things that are actually mostly likely to hurt us. Our brains’ admirably lightning-fast danger-detection system evolved in an environment different from the modern world, so it tends to trigger our alarms when the situation isn’t really that grievous. Worse, it can fail to activate when we really are faced with a real-and-present danger, leaving us prone to walk right into potentially harmful situations. That doesn’t mean we’re totally SOL, however. With a little effort we can consciously arm ourselves with rational risk-benefit analysis and try to override our erroneous automatic impulses.
For example? Here are some perceived dangers that get blown out of proportion:
Cell phone radiation. Uncertainty is a powerful trigger of anxiety. When new technologies reach a broad public, they can seem uncomfortably mysterious, and hence ready targets for health-scare furors. Remember Alar, silicone breast implants, electromagnetic fields from power lines? In the case of cell phones, the word “radiation” adds additional emotional baggage. The fact is, numerous studies have failed to turn up any conclusive evidence that cell phone emissions pose health risks, and the physics suggests it’s most likely impossible.
Vaccinations. We tend to be less afraid of things that provide an immediate, palpable benefit. The problem with vaccinations is that we never really know if they’ve helped us or not. What’s more, we’re intuitively suspicious of things we perceive as artificial rather than natural. These biases have helped stoke widespread panic about childhood vaccinations, which in turn expose kids to very real risk. Continue reading Why Your Brain’s Wrong About Danger
