The Wisdom of Crowds vs. The Smart Money - Again

January 4, 2015

Several posts in this blog have looked at the “wisdom of crowds” in football betting. In brief, the wisdom of crowds idea asserts that the collective opinions of the many are more accurate than the opinions of a few experts. (For a fuller explanation, see this post from 2009.)

Today’s playoff game between the Bengals and the Colts provides an example. The crowd loves Indianapolis.  Two-thirds of bets have been coming in on the Colts, who opened as 4-point favorites.  Nevertheless, early in the week, the line went down to 3 ½.  Apparently, the bettors who the bookies most respected, were taking the Bengals, even though the Bengals' star receiver, A. J. Green will not be playing.

Today, the public has continued to bet the Colts, with the result that some books have raised the line back to 4. 

The smart money is still on the Bengals. But if you believe in the Wisdom of Crowds, you should be on the Colts.

UPDATE:  The smart money wasn’t. The crowd was wise. The Colts easily beat the Bengals 26-10.

Names Ending in N

A post at FiveThirtyEight (here), by Nate Silver and Allison McCann, has the title, “How to Tell Someone’s Age When All You Know Is Her Name.”* But if the person in question is a male, you might make an equally good guess with one letter – the final one.

In a 2009 post (here), I had some graphs showing the rise of boys names that end in the letter N.

 That trend that had gone largely unnoticed, probably thanks to the availability heuristic.  It’s much easier to think of names and words that start with a given letter rather than those that have that letter elsewhere. Especially with names, we’re more likely to think in terms of initials.

Those data were from 2006. The trend has continued in strength. The FiveThirtyEight post shows the historical change in a slightly different way. Instead of looking at the popular names in each year, Silver and McCann show the age range of people with each name.  Here are the twenty-five oldest names.  The graph shows the median and the inter-quartile range. For example, the median Willard is 65 (the median for all males is about 37); half of all Willards are between ages 51 and 75.


And here are the youngest 25.


Among the oldsters, only Norman and Herman sport the final N. But in the 3-10 median age group, 14 of the top 25, including eight of the eleven youngest, end in N. 

I am at a loss as to how to explain this. It could just be one of those cases of unintentional and unconscious influence. With some names, the imitation with slight variation is more overt – Aidan, Jayden, Brayden, Kayden, et al. But for those others – Landon, Mason, Julian, and the rest – maybe there’s something about that final N that, like the music of Mumford and Sons or Kings of Leon, sounds just right to the ears of 21st-century parents.

Police, Protests, Police Protests, and Legitimacy

Steve Anderson, the police chief of Nashville deserves some kind of an award.

The city of Nashville had protests about the shootings in Ferguson and elsewhere. The police department respected the rights of the demonstrators. The department even blocked of part of the Interstate for them and provided them with hot chocolate. No violence or destruction of property resulted.

Not everyone in Nashville was happy with the policy. You really have to read the letter he wrote explaining his policy to a disgruntled citizen.  Actually, he explains a lot more. The Nashville.gov page (here) starts with Chief Anderson’s message to his police officers (nice, but not required reading), followed by the citizen’s letter (very civil in tone). (MNDP is probably Metropolitan Nashville Police Department, THP Tennessee Highway Patrol).

The Chief’s answer is a gem. Matching the civility of the citizen, he nevertheless points out the empirical and logical flaws. He writes in plain English, slightly formal but with no academic terms. Still, I would guess that he has some background in political theory, cognitive psychology, and sociology.

I did not find much that seemed directly relevant to the recent police actions and inactions here in New York. But there is this: Anderson starts by quoting the citizen.

“I have a son who I have raised to respect police officers and other authority figures, but if he comes to me today and asks "Why are the police allowing this?" I wouldn't have a good answer.”
[The Chief responds:]
It is somewhat perplexing when children are injected into the conversation as an attempt to bolster a position or as an attempt to thwart the position of another.  While this is not the type of conversation I ordinarily engage in, here are some thoughts you may find useful as you talk with your son.

First, it is laudable that you are teaching your son respect for the police and other authority figures.  However, a better lesson might be that it is the government the police serve that should be respected.  The police are merely a representative of a government formed by the people for the people—for all people.  Being respectful of the government would mean being respectful of all persons, no matter what their views.

You have to admire the Chief for nailing the citizen’s rhetorical strategy (“I have a son . . .”).  More important is the chief’s understanding of the relation between the police and the government.  Adding in the NYC conflict,I would go further. The police have a unique power – the general right to use force and violence. But that power is legitimate only if the police serve the government – a duly and democratically elected government. If the police use that power to oppose the government, to engage in partisan politics, to give vent to their petulance, or to further their self-interest (the police union is still in negotiations with the city over their contract), they risk losing their legitimacy. 

It would also be interesting to see how the opinioneers on the right and the left are framing these issues. As Peter Moskos* (here) and perhaps others have pointed out, it’s complicated. The tangle of ideology includes strands labeled Government, Police, Race, Unions, and now Crime and Broken Windows. But perhaps the underlying or ultimate issue, one not explicitly spoken of, is legitimacy.

Horton Hears a Whom?

In discussions of  language and grammar the word correct should usually be in quotes.  Either that or it should be amended to “currently correct.” That goes for pronunciation and spelling too. The trouble is that language prescriptivists seem to think that what is currently correct has always been so and always will be. They’re wrong.

NPR recently asked listeners for their language gripes – “the most misused word or phrase.” Topping the list was “I and “me.”  (The full list is here.)

Strictly speaking, “the gift is for you and I” is wrong. We have objective pronouns (me) and subjective pronouns (I). Putting a couple of words between the preposition (for) and the pronoun doesn’t change that. If you wouldn’t say, “The gift is for I,” then don’t say, “The gift is for you and I.”*



Strictly speaking, it should be “between you and me.”  But we don’t speak strictly. Language changes. Yesterday’s solecism becomes today’s standard usage. I don’t like “between you and I,” but wishing people would stop using it is like wishing they’d stop texting. (Need I point out that text as a verb did not exist until very, very recently?)

At #9 on the prescriptivists list is
Saying someone “graduated college” instead of “graduated from college.”
They don’t have too much to worry about. Their preferred form is ten times more common, at least in books if not in speech.


But not too long ago, “he graduated from college” was itself a grammatical error. NPR, in the very next sentence, says,
A college graduates a student, not the other way around. The “from” makes a big difference.
But while NPR sees why this makes “he graduated college” incorrect, it fails to note that by this same logic, “he graduated from college” is also wrong.  If it’s the college that graduates the students, we should say “he was graduated from college.” And in fact, we did say it that way.



Imagine a newspaper in 1900 asking the NPR “most misused word or phrase” question. High on the readers’ list of grammar gripes: “Even our best educated are now saying, ‘I graduated from Harvard,’rather than the correct, ‘I was graduated from Harvard.’”

“Was graduated from” was never the most popular way of saying it, but it held its own up until about 1950. Since then “I graduated from” became the clear winner and is now, at least among the NPR complainers, the “correct” form.

Coming in at #5 on the list is
Ongoing confusion over “who” vs. “whom.”
The confusion is easily cleared up: get rid of whom. Reserve it for a few special occasions.  In fact, that’s what’s been happening.



The graph from Google Ngrams shows the frequency in books, i.e. formal writing. The misuse of whom can escape copy editors even at the Times :
The defenders of the interrogation program say little about two men whom are portrayed especially harshly by the Senate report

Surely whom is fading even faster in everyday speech. I’m surprised that NPR could find even a few dozen people who mourn its passing. I am certainly not among them. (Or should I say that I am not amongst them?)

* The root of the I/me problem is that English lacks a disjunctive pronoun. The French, thanks to  moi, toi, etc., never make these mistakes.
