Critical Thinking

I spent much of yesterday on a flight from New York to Los Angeles. As usual, on a crowded flight, it’s impossible NOT to hear conversations when people are trying to yell over aircraft noise. Before I put on my noise-cancelling headphones and tried to catch a quick catnap, I heard the following from the seats behind me:

Person 1: “I was reading about this Intelligent Design stuff in the New Yorker. It seems like a pretty solid theory but they won’t let it be taught in the classrooms and that’s not right.”

Person 2: “It’s not science though.”

Person 1: “Why not?”

Person 2: “There’s no scientific evidence to back it up. I was reading this article in the paper. Even the people who are pushing it don’t agree on some of the things they want the public to know.”
The conversation went on for a while, morphing into a discussion of current politics in the United States. I put my headphones on and went to sleep. But the whole thing got me to thinking that perhaps what we really need in our science classrooms is more emphasis on critical thinking, of helping students (and maybe society in general) develop better B.S. detectors.

There’s a difference between theory and hypothesis, but to hear proponents of such ideas as Intelligent Design and Creationists tell it, the two words mean the same. This is because both camps have put forth hypotheses about the origin of everything in the universe. Fine. In science, when we have a hypothesis, we then devise tests that provide data to either prove or disprove the hypothesis. Now let’s do some tests to prove or disprove those hypotheses. Otherwise, conflating “hypothesis” with “theory” is NOT critical thinking, nor is it intellectually honest.

Some food for thought:

Here’s the Dictionary.com definition for “hypothesis.”

Here’s the Dictionary.com definition for “theory.”

Of the two, the word “hypothesis” fits the ideas that the IDers and Creationists want to teach. But they are NOT theories, specifically because there is no data to support the central tenet of each set of hypotheses: i.e., that there’s some creator out there flinging universes together on some timeline known only to itself.

I’m of two minds about whether this stuff should be taught in schools. Perhaps it should. But I don’t think it has a place in the science classroom for two reasons: there’s not enough time to teach honest, true science, let alone wasting time on hypotheses that have more to do with religion and culture; and two, we don’t teach science in comparative religion and other such classes.

On the other hand, a good, honest, dispassionate application of the scientific method to these hypotheses is exactly what science does best. So, therein lies the central dilemma.

No matter where this stuff is taught, it should all be subjected to the same rigid tests that true science and critical thought require. To do otherwise is to admit intellectual laziness. And such an admission in the name of a religion or belief system does little FOR such beliefs and systems, other than to set their adherents up as less than intellectually honest in their intentions, something that I (brought up in a religious family I was) was taught would be a waste of the intelligence and reasoning faculties we were born with.

Advertising and Critical Thinking

I’m starting today’s discussion with advertising. No, it’s not a science thing, but I’ll get to that in a minute.

My first question is, why do some advertisers think we’re so stupid that they have to produce such staggeringly dumb ads?

Like, I’m REALLLLY going to run out and buy a Kia because they have two black women staring daggers at each other over who paid less for their cars. Sure.

Does the world really need that sort of silly crap?

How about the whiny guy who’s obviously put out at having to care for his own children for an hour or so while his wife is out getting a little time to herself doing some shopping? (The JC Penney ad.) Like what Neanderthal dig did the writers pull that crap from? (My apologies to the Neanderthals.)

Does every state in the union have some ditzy blond or ditzy married couple selling cut-rate furniture using obviously home-made ads? In Colorado it was Jake Jabs (probably still is). It was Gary and Marcy Levine until they went belly-up. In Massachusetts it’s Bernie and Phyl’s. Stupidest ads in the world. They look like they cost about 2.5 cents to shoot (and probably the writers only got a half cent and no credit). And don’t get me started on the car dealers… who cares if it’s Toyotathon time again?

(On the other hand, the two guys who run Jordan’s furniture actually have some clever ads — there’s some THOUGHT that went into those ads — which is why we bought some furniture from them.)

But, I suppose that nobody ever went broke underestimating the stupidity of what sells in advertising.

Okay, now that that’s out of my system, let’s talk about what people want to know about astronomy.

I used to do a lot of public talks about astronomy — here, there, everywhere. Contrary to popular belief, most people didn’t ask me to give them horoscope readings after my lectures. That’s because the folks who attended these talks (at planetariums, science centers, etc.) were there because they already knew something about the subject and they knew it had nothing to do with some ancient superstition. These were folks who come from all walks of life, who are obviously interested in the universe around them. They’re lucky, because when you go out questing in the cosmos, you come back with some cool stuff. If you sit on the couch and let the universe come to you, you’re not gonna get much that’s cool.

So, what interests folks about the stars?

Black holes.

Supernovae.

The end of the universe as we know it.

How the universe got started.

Life on other planets.

What will happen when the planets line up in the sky (which happens frequently but never causes any problems).

I once had the chance to lecture right after John Dobson gave a public talk. John’s a feisty guy, and sometimes he gets off on a rant about cosmology, but he’s always got something pithy to say. John had a group of kids in front of him and he had them spellbound about cosmology. Using words they could understand, he kept their attention and engaged their minds.

So you see, it can be done. How many Kias would they sell if they only used their brains instead of letting the “creative staff” hook their gonads up to the computers and play with themselves?
