Boys and Girls at STEM


Let me start by expanding a term used throughout this blog: STEM. It stands for “Science, Technology, Engineering and Maths”. Now for the provocative question: why are boys better than girls at STEM?

Here’s an economist, Alex Tabarrok’s take on the subject. He talks of the so-called “gender-equality paradox”:
“Countries with the highest levels of gender equality tend to have the lowest ratios of women to men in STEM education.”
Yes, that means those famed Scandinavian countries! The usual explanation for this is that “less is riding on choice of career in the richer, gender-equal countries”. In other words, the benefits of a higher paying STEM job in those countries gets eaten away by high taxes, and in any case, the state takes good care of you regardless of career choice…

Another reason for the STEM question is that males have a higher variability. “Variability” means that there are lots of boys who excel at things and equally, there are lots of boys who are terrible at those very things. The extremes for boys, both on the good and the bad side, are, er, more extreme.

Then there’s the fact that girls are better at reading skills in almost all countries. But wait, there’s more:
“Even in countries where (girls) are better at math and science than boys on average they are relatively better at reading.”
I’ll reiterate that last point: even if girls are better than boys at STEM, they are better than boys at reading by an even higher margin.

Keep that in mind when you read the next point:
“Now consider what happens when students are told. Do what you are good at!”
See where the “crushing grip of reason” (as Calvin told Hobbes) leads to:
“Loosely speaking the situation will be something like this: females will say I got As in history and English and B’s in Science and Math, therefore, I should follow my strengthens and specialize in drawing on the same skills as history and English. Boys will say I got B’s in Science and Math and C’s in history and English, therefore, I should follow my strengths and do something involving Science and Math.”

This “comparative advantage” aspect to this that doesn’t get talked of as often. As much as the (possible) genetic aspect. Of course, the latter makes people squirm. Something one guy commented on:
“In absolutely no way is it sexist to suggest that men are generally inherently better at some things and women at others. Why are you so terrified of this truth?”

So which is it? Genes? Or the comparative advantage reason? Or a bit of both?

Student of the Year

Image
As a toddler, my daughter loved Alia Bhatt’s songs, esp. the ones from Student of the Year . (That movie did have many good songs and well-choreographed dances). Fast forward to present day, when she is 12 yo. She rarely watches Hindi movies now, but one of the few ones she likes of late, Raja aur Rani ki Prem Kahani has, yes, Alia Bhatt.   If I had any hopes that there was anything to be read in the name of her toddler-time favorite ( Student of the Year ), they have been dashed. Our conversations come exam time are perfectly captured by this photo and its caption: In fact, the pic below captures how she and I look at her answer sheets – me intently, she with an expression of “It’s over, so why are you even looking at it?”   Of late, we pull her leg and tell her that she isn’t showing any signs of academic prowess, she’d better find a rich guy to marry. Some time later, she showed us this meme on the Internet: “Me No Study, Me No Care Me Go Marry Millionaire If He Die

Animal Senses #7: Touch and Remote Touch

Instinctively, we think touch is based on contact. Not entirely true, explains Ed Yong in Immense World – there’s a more important aspect than contact: “These incredible feats are possible through movement. If you rest a fingertip upon a surface, you can get only a limited idea of its features. But as soon you’re allowed to move, everything changes. Hardness becomes apparent with a press. Textures resolve at a stroke.” As you run your fingers over a surface, they hit the tiny peaks and troughs and set off vibrations in the mechanoreceptors at their tips.   At the tip of its snout, the star-nosed mole has many pairs of hairless appendages. It uses them to touch things around itself. Alive or dead? Food or ignore? It does these movements at an insane speed. In the time it takes to blink our eyes, the star-nosed mole can probe, identify and swallow its food. “Light may be the fastest thing in the universe, but light sensors have their limits, and the star-nosed mole’s sense of

The Retort of the "Luxury Person"

Image
Coming up with biting and witty retorts. It’s something we dream of, but rarely manage to pull off. Worse, the more we stew over the offending remark, the more likely we are to come up with that dream retort, as Calvin ruefully points out: During our last holiday at the Taj Resort, seeing my wife carrying towels to our poolside chairs, one of the kids there mistook her for a member of the staff and asked for a towel. When my wife narrated this to us, I did not imagine that my 8 yo daughter would come up with her own retort. But a day later, my daughter recapped the incident, an incident that didn’t even involve her in the first place , and said, “You know what I’d have told that kid who asked for the towel?”. And without waiting for an answer, she told us anyway: “I don’t work here. I too am a luxury person who is living at this resort. Go get your own towel.” We were highly amused by the phrase she had coined: “luxury person”. It certainly captures the kind of holid
