From a comment by me, elsewhere

We as a species have always suffered from various depravities, be they slavery (which continues to this day in a black market), murder, rape, and war. These things existed a thousand years ago, and I highly doubt that they will be eradicated 1000 years in the future. What has changed is the technology that allows us to kill (and save lives) much more efficiently, and the media that allows for the rapid dissemination of information. I don't know the ultimate end of these changes, but my guess is that as broadcasting information gets cheaper, the forces above he despises will lose power, or have already lost some power. I think we're in a better place than we were 90 years ago, when women in this country were first allowed the ballot.

That doesn't mean that the future cannot be seen as black now, but instead that the future was black in the American Revolutionary War, when Washington's army froze at Valley Forge, and that the future was black at Gettysburg as the South fought to retain a right for slavery and the Union fought to retain the South in a war that was enabled by decades of failed leadership, and that the future was black when Bull Connor unleashed dogs and hoses at the marchers in the civil rights movements, and that the future was black all of those years Nelson Mandela sat in prison.

But the King's army was defeated, and the Union maintained, and slavery ended, and civil rights won, and apartheid ended, not because we saw the world as inherently flawed and worthy of condemnation, but because we know that " the arc of the moral universe is long but it bends toward justice." - MLK

I think hope is a much better motivator than despair.

What a Williams degree prepares you to do....



And yes, I am still drafting the rankings post and will get it up when I can.

Rankings, philisophical

I'm out of writing power, so here's a preview list of the topics I'll hit tomorrow:
  • Williams's way of dealing with the rankings
  • How Williams policies improved our standings
  • How other schools have done much worse stuff
  • The impact of low "reputation" response rates.
  • Poor incentives and their consequences.
  • How rankings get used.
This will probably be followed by a post about why Williams is the best college in the country for all of its unquantifiable factors.

Rankings in detail: arbitary comparisons

After a long day returning to the office from a fabulous Eph vacation, little could have warmed my heart more than the kind complement from ShuffStuff @ Tumblr, and hope that these musing manage to satisfy. I also wrote a shortened version of the below a few days ago when the Forbes rankings came out.

Let's start by taking a look at what US News says about their rankings:
  • Do use the rankings as one tool to select and compare schools.
  • Don't rely solely on rankings to choose a college.
  • Do use the search and sort capabilities of this site to learn more about schools. Visit schools, if possible.
  • Don't wait until the last minute. College matters. Take your time, and choose carefully.
  • Do think long and hard about the right place for you.
The problem, of course, is that the text above is two clicks away from the main rankings page, which lacks any sort of guidance about how to use the rankings. Why? Because the entire point of the rankings is to be a big deal, which makes US News a big deal. I can't think of a time that the magazine is in the news except for these annual rankings, which might be why Forbes just started its own rankings. Any sort of equivocation (a la "these rankings are part of balanced breakfast of high school counselors, visits, research, etc") would only hurt the impact of the rankings.

Because, let's face it: they're sexy. The world of higher ed is a heck of a lot easier to understand when you have a clear numerical order of every single US college. Far from adding any doubt, US News puts the top three in each category on a pedestal as if to say: these are the best places to get a good education because..... why? Let's see (subpoint percentages are the fraction they represent of that subsection:
  • Undergraduate academic reputation (22.5 percent of total ranking)
    • 66% peer assessment (48% survey response rate)
    • 33% high school counselor assessment (21% survey response rate)
  • Graduation and Freshman retention (20 percent of total ranking)
    • 80% 6-year graduation rate
    • 20% freshman retention rate
  • Faculty resources (20 percent of total ranking)
    • 30% proportion of classes with fewer than 20 students 
    • 10% proportion with 50 or more students
    • 30% Faculty salary (adjusted based on cost-of-living differences)
    • 15% proportion of profs with highest degrees in their field
    • 5% student-faculty ratio
    • 5% proportion of faculty that are full-time
  • Student selectivity (15 percent of total ranking)
    • 50% entering classes SAT Math/Verbal & ACT composite scores
    • 40% proportion of students from top 10% of their high school (GPA)
    • 10% acceptance rate
  • Financial resources (10 percent of total ranking)
    • Spending per student on "instruction, research, student services, and related educational expenditures."
  • Graduation rate performance (7.5 percent of total ranking)
    • Performance of the class of 2003 relative to an "expected graduation rate" based on Pell Grants, SAT Scores, etc.
  • Alumni giving rate (5 percent of total ranking)
    • Percentage of alums who gave to Williams two years
The above isn't quite as sexy as "Williams is the #1 college in the US," is it? In fact, it makes damn little sense, if for no other reason than that all of these ranking tools are based on different variables. Even if test scores are 1.25 times as high school performance, how do you compare school A (with avg SAT of 1400 and 50% of frosh who were top-ten percent in high school) to school B (with avg SAT of 1350 and 60% frosh who were in top-ten percent in high school). You can't!

In order to do so, you have to state some sort of equivalency between them: that every 10 points in SAT is worth some percentage of high performing students in high school. How do you set this?  How do you compare differences in faculty salary (crudely adjusted on regional indexes that have little to do with the cost of living (COI) in a college town with percentage of classes with under 50 students?

I see seven different and incomparable variables up there (reputation survey score, percentages, money, student-faculty ratio, SAT score, ACT score, "graduation rate performance.) These variables cannot be compared without an arbitrary relative weight of . No such formula is dependable unless you use statistics to make a z-score that depends on the distribution of each of the variables, but this incredibly unsexy method is still arbitrary, albeit mathematically.

So to sum up: Arbitrary comparisons of unrelated variables are arbitrarily weighted within subcategories, which are then arbitrarily rated together to produce a composite score such as "100," for Williams. And since Williams's 100 is almost certianly based on a curve, that means that every other score is also curved according to a formula that isn't disclosed.

In short: These sexy rankings aren't quite so nice looking when you strip them down.

    Williams again takes #1 spot in US News

    Again, rankings are dumb for a myriad of reasons, but that's no reason not to celebrate when they get something right. :)
