What is an algorithm?

An algorithm often requires a model.

What is a “model”?

. . .

nothing more than an abstract representation of some process, be it a baseball game, an oil company’s supply chain, a foreign government’s actions, or a movie theater’s attendance (O’Neil 2016, p. 18)

How do you create a model?

. . .

we make choices about what’s important enough to include, simplifying the world into a toy version that can be easily understood and from which we can infer important facts and actions (O’Neil 2016, p. 20)

Arms race: Going to college

Why rankings are a racket

“How to Game the College Rankings”

Northeastern University executed one of the most dramatic turnarounds in higher education. Its recipe for success? A single-minded focus on just one list. (Kutner 2014)

What is a successful college?

. . .

[Scores] couldn’t measure learning, happiness, confidence, friendships, or other aspects of a student’s four year experience.

President Lyndon Johnson’s ideal for higher education “a way to deeper personal fulfillment, greater personal productivity and increased personal reward” didn’t fit into their model. (O’Neil 2016, p. 52)

What is a proxy for success?

. . .

Instead they picked proxies that seemed to correlate with success. They looked at SAT scores, student-teacher ratios, and acceptance rates… They calculated the percentage of living alumni who contributed money to their alma mater, surmising that if they gave a college money there is a good chance they appreciated the education there. (O’Neil 2016, p. 52)

Consequences??

. . .

Monomania

Colleges were like different types of music, or different diets. There was room for varying opinions, with good arguments on both sides. Now the vast reputational ecosystem of colleges and universities was overshadowed by a single column of numbers (O’Neil 2016, p. 53)

Cheating/gaming

Faux faculty

the Saudi university had contacted a host of mathematicians whose work was highly cited and had offered them $72,000 to serve as adjunct faculty (O’Neil 2016, p. 62)

Admissions consultancies

A four-day “application boot camp,”… costs $16,000 (plus room and board)…. the high school juniors develop their essays, learn how to “ace” their interviews, and create an “activity sheet” the sum up all the awards, sports, club activities, and community work that admission officers are eager to see.

the college admissions game, while lucrative for some, has virtually no educational value (O’Neil 2016, p. 64-65)

Brittle about students

Cost wasn’t in the model

[Colleges] had a commandment to maximize performance in fifteen areas, and keeping costs low wasn’t one of them…

Higher Ed ↑500% (4x inflation) from 1985–2013

to attract top students, colleges … have gone on building booms, featuring glass walled student centers, luxury dorms, and gyms with climbing walls and whirlpool baths (O’Neil 2016, p. 60)

Obama’s fix

Focus on cost and employment, which led to:

Result

the government capitulated. And the result might be better. Instead of a ranking, the Education Department released loads of data on a website.

Think of it: transparent, controlled by the user, and personal. You might call it the opposite of a WMD. (O’Neil 2016, p. 67)

How has this affected Northeastern?
