Science

“We live in a society absolutely dependent on science and technology and yet have cleverly arranged things so that almost no one understands science and technology. That’s a clear prescription for disaster.”

—Carl Sagan

“What counts is not what sounds plausible, not what we would like to believe, not what one or two witnesses claim, but only what is supported by hard evidence rigorously and skeptically examined. Extraordinary claims require extraordinary evidence.”

—Carl Sagan

Not all science is created equal.

I think of science as a verb, a process for discovering what's true, rather than a body of knowledge. Some people might say it's a process for discovering what's not true; that might be more accurate. In either case, when I run into people who distrust science, I wonder if they see it the same way.

Although I strive to only relay accurate, evidence-based information, when I'm asked about medical issues, I nonetheless habitually remind listeners that I'm not a doctor and that my advice should be taken with a grain of salt. I think this is especially important online, where commentary from a medical doctor and commentary from a nutjob are visually indistinguishable.

How many conspiracy theorists and self-certified Facebook epidemiologists do this?

“The unleashed power of the atom has changed everything save our modes of thinking.”

I consider myself a skeptic. I try not to believe anything that isn't supported by commensurate evidence. In my mind, a claim is a sacred thing, something to be carefully considered, not taken for granted or believed for some practical purpose.

Moderation is important, of course, but this is my default outlook. I want to know what's true about the world. Very little is more important to me.

Maintaining credibility is useful, too. I want others to take my views seriously. That might be harder if I had a reputation for believing things that aren't true.

I want to believe as many true things and as few false things as possible. Although it's often painful, I appreciate when evidence proves me wrong. The alternative is worse; running away from uncomfortable truths brings neither comfort nor growth.
