Welcome back to "Doggerel," where I ramble on about words and phrases that are misused, abused, or just plain meaningless.
Woos like to speak this line without thinking about its implications. This skeptic's response to the assertion: Well, duh!
Right now, we are in a torrential rain of tiny, invisible particles called neutrinos. Right now, we are in a sea of light we can't see: Radio waves, microwaves, infrared, ultraviolet, and even some x-rays and gamma rays (hopefully at low, safe levels where you are). There's all sorts of such invisible things going on right now. We know our senses are limited.
But even with all our detection equipment designed to help us sense those otherwise invisible forces, skeptics know that our perceptions are flawed. Our minds naturally try to find order, patterns, and explanations. The trouble is, we're often too good at it for our own good. Some patterns we perceive don't exist. Some relationships are forced when we unknowningly bias towards confirming data points and ignore those that don't fit with perceptions.
That's why we push for scientific rigor. All the methods we push exist to minimize or eliminate biases we have as mortals. We don't just blindly trust that the world is as it seems to our initial impressions. If anyone does, it's typically the woos who spout this doggerel.
