From the New York Times:

While scientific literacy has doubled over the past two decades, only 20 to 25 percent of Americans are “scientifically savvy and alert,” he said in an interview. Most of the rest “don’t have a clue.” At a time when science permeates debates on everything from global warming to stem cell research, he said, people’s inability to understand basic scientific concepts undermines their ability to take part in the democratic process.

I can sympathize, this is something I encounter more and more as I try to explain acoustical concepts to lay people – for example, people don’t understand concepts like decibels and A-weighting so they dismiss these metrics even though they can be very effective at predicting annoyance from noise.

But in the end, as a consultant, it’s my job to help people to understand these things. But sometimes I wish it was just a bit easier.
