Bad Graphs

In the wake of the announcement of Harvard's first wave of '18 admits, the Harvard Crimson is reports on the high-school demographics of Harvard's student body. The investigative article sheds some sunlight on just how much inequity exists between privileged "Harvard feeder schools" and the rest of the downtrodden teenaged proletariat.

Graph featured on The Crimson

That is, surprisingly little.

Oh, sure; the graph is concave. That means that...some schools sent more kids than other schools. Huh. How many more? Well, just reading the graph, something like 45% of Harvard students were the only admit from their school, and something like 78% are one of three or fewer kids from their high school. By contrast, the top schools send...15. A whopping five times more. Um. Right.

For contrast, this is what real inequity looks like:

Things on the right are people with obscene amounts of money. For reference, poverty-line America is ~95%tile.

(Yes, they're graphing different things, but the mathematical point remains valid.)

Or, on a brighter note, the cost-effectiveness of different world health interventions:

Things are the right are awesome ideas we can be doing even more of.

So yes, some high schools send ~15 students to Harvard every year. Some send one every ~4 years. The real problem, of course, is the high percentage of schools that never have sent a student to the Ivy Leagues, and never will. Or, for that matter, the gigantic percentage of people in this world who had the misfortune to be born in a place where education through high school wasn't mandatory, easy, or even available. But that, of course, doesn't show up on the Crimson's graph, because that wasn't part of

Epiphany at the Petting Zoo

Harvard owns a petting zoo.

In the grand scheme of things, this is not exceptionally surprising. Harvard also owns such disparate objects as a hundred-year-old printing press, a forest in central Mass, and a fleet of Harvard-insignia waffle irons.

In Harvardese, "Veritaffle". You can't make this stuff up.

I don't know how long the zoo has been Harvard's; at least, I remember the bunnies being used to promote Leverett House (whose mascot is a hare) on housing day in March, and the full zoo making an appearance at Eliot House's welcome-back barbecue in September. Nowadays, it's become a weekly fixture in front of the Science Center on Thursday afternoons. To paraphrase one of my professors: "There's no more relaxing way to spend 20 minutes on a Thursday afternoon."

Particularly in need of quick relaxation after Math 131, I made my own stop by the petting zoo. At that point, they were just setting up, and the bunny pen was surrounded by people standing around and looking at -- but not touching the bunnies. No one wanted to be the first one to get down on their hands and knees and pet one.

Having no such reservations, I knelt down and lifted out one of the longhairs (being careful, of course, to support the spine and hindquarters -- I owned a rabbit for many years back home in Maryland). Someone behind my asked "Oh, you can do that? Is it going to bite me?"

Over my shoulder to the woman I couldn't see (I didn't want to turn around with a small rabbit on my lap...), I said "Sure, just keep one hand under his butt,
