Curious Reasoning of True Believers

If you believe in magic, come along with me
We’ll dance until morning till there’s just you and me
And maybe, if the music is right
I’ll meet you tomorrow, sort of late at night
And we’ll go dancing, baby, then you’ll see
How the magic’s in the music and the music’s in me

The Lovin’ Spoonful

The illustrious blogger Fandango has posed the question today: Do you believe in magic? Quite a can of worms, isn’t it? This is partly a question of definition and categorization, taxonomy as much as philosophy. What’s just as interesting is the blurred lines between religion, magic, expertise, intuition, evidence, and conclusions without evidence, and how they lead people to take actions that are self-contradictory.

The question was instigated by a recent incident in a Tennessee Catholic school where the pastor removed the Harry Potter series from the elementary/middle school library because: “These books present magic as both good and evil, which is not true, but in fact a clever deception. The curses and spells used in the books are actual curses and spells; which when read by a human being risk conjuring evil spirits into the presence of the person reading the text.”

Well, as Hermione might say, Revelio!

Is it a Natural Law If I Don’t Know it Exists Yet?

But first, definitions are required if we’re going to talk about magic and belief. Belief refers to a personal conviction which can either be backed up by facts or not. Belief can be based on unseen evidence. I believe that antibodies and quarks exist because scientific studies have identified them and described how they work. I don’t have to see them. Belief can also occur without evidence. I believe that people have experienced things not yet explained by science, such as dreaming about things that occur in reality but outside the dreamer’s knowledge.

Magic, according to Merriam-Webster, is the art of producing a result …through human control of supernatural agencies or of the force of nature. Hmmm. So what is supernatural? Beyond what is natural; unexplainable by natural law. (I’m excluding stage magicians here, who perform amazing tricks through explainable but complicated processes such as hidden doorways or misdirection.) What this definition points out is that magic, in essence, is something that occurs which is unexplainable. Let’s also add: CURRENTLY unexplainable.

Yes, You Can Drink Cold Water

My yoga teacher told us a few weeks back that we should refrain from drinking cold water, either with meals or at any other time. This led to a pointed rebuke from another long-time student who had an extensive nutritional background, and the merry debate went on until the instructor ended with, “Well, this was what they told me in a physiology class that I’m taking.”

I remembered this exchange reading last week in the NY Times about a study which showed people often cling to ideas which conflict with scientific consensus and common sense. Further, that those who often feel strongest are often the least knowledgeable. Although this seems counterintuitive , almost surreal, we have seen this in action. In fact, this conundrum seems to be one of the most pressing problems of our time, one which, despite the ready availability of good information, persistently leads to the opposite. Case in point: reactions to the Mueller report. Case in point: the recent outbreak of measles, which ought to have been eradicated in the U.S. Case in point: see my post about eating cheese.

Why do easily validatable yet unsubstantiated ideas get so easily disseminated and supported? Perhaps it is a function of our response to the Information Superhighway which gives us 1) too much information 2) sometimes delivered by the unscrupulous which leaves us to be 3) overly reliant on people we (think we) can trust. Because 4) you can drink cold water.

War Over the Thermostat

As hundreds of tornadoes blasted across the midwest this past week, the impact of climate change popped up in a more mundane but perhaps significant way in two New York Times articles about room temperature. A recent study found that energy consumption increases as you get older, especially quite old, meaning a lot older than I am right now. Another study showed clearly that women and men perform cognitively very differently depending on the temperature. Both of these studies suggest our battles over the up and down arrows on the thermostat are just beginning.

Over 70? Never Be Without a Snuggie

A study published in Energy Research and Social Science looked at the use of energy stratified by age, including impact from variables of income and housing size. The data from 1987 to 2009 used pseudo-cohorts, a sciency way of saying that the study was designed to look at age groups that changed over time. In other words, they looked at energy consumption by age, and they followed those age groups for about twenty years.

From “Age matters: Ageing and household energy demand in the United States” in Energy Research and Social Science, September 2019

Apparently young people don’t use as much household energy, most likely because they run around and live in small rooms, like dorm rooms. Multi-person families buy bigger houses, so that the entire family uses relatively more energy, which seems to pick near age 50. Energy use then decreases, but starts to drive upward again after age 70.

When the researchers added income to the model, the upward slope tipped even higher, meaning that having more income when you’re older magnified the impact. This wasn’t true for those under age 30, though. Whether income was included or not, people in their twenties don’t use as much energy, whether they can afford it or not. A lot of the increase in use as people get older was due to housing size, though not all of it.
