The Observer Effect and Using Google for Social Science

I thought this was an interesting quick and dirty social study using Google. (via Knowledge Problem)

For any individual study you can validly say that you think the estimate is too low, or indeed, too high, and give reasons for that. For instance, you might say that your sample was mainly young people who tend to be healthier than the general public, or maybe that the diagnostic tools are known to miss some true cases.

But when we look at reporting as a whole, it almost always says the condition is likely to be much more common than the estimate.

For example, have a look at the results of this Google search:

"the true number may be higher" 20,300 hits

"the true number may be lower" 3 hits

I often tell folks that the key to understanding behavior is to understand incentives. The media as institutions have incentives to sensationalize and scare (it sells papers) and as individual reporters have incentives to magnify the importance of whatever story he or she is working on.

But what I found really interesting was how the Observer effect comes into play here.  Wikipedia has this brief definition of the observer effect:

In physics, the term observer effect refers to changes that the act of observation will make on the phenomenon being observed. This is often the result of instruments that, by necessity, alter the state of what they measure in some manner.

Click on the Google hit numbers above.  I get 42,700 and 5,360 respectively, the increase presumably due in part to this article and links to it.  Its impossible to report on patterns in Google searches without the very fact of such reporting affecting what is being measured.

Market Manipulation...For Eight Minutes

A while back, I wrote of my conversation with a friend who was convinced that oil prices are set by a small cabal of traders, and that while they have been at $60-70 over the last several years, they would have been at $40 or less without the traders manipulating the price.  I won't go into my arguments again here, but I wrote that it would be virtually impossible to maintain a price artificially above the market clearing price for so long without 1) massive product gluts or 2) almost-impossible-to-hide widespread suppression of production involving thousands of parties.

Michael Giberson at the Knowledge Problem writes about a price-fixing case by natural gas traders.  Amaranth is accused of manipulating gas prices, and I won't judge their guilt or innocence.  But, apropos of my statement above, it is interesting to note that the key question is whether it was possible for the company to manipulate commodity prices for eight minutes.  It looks as if they tried it, but it also looks as if they were not successful (since the government is charging they attempted to manipulate the market, but is not trying to prove they succeeded in doing so).  Making it hugely absurd to think that anyone could do it for three or four years.

The Joy of Blogging

I guess it's become de riguer to take a shot at Joseph Rago's editorial in the WSJ the other day, saying in part:

Some critics reproach the blogs
for the coarsening and increasing volatility of political life. Blogs,
they say, tend to disinhibit. Maybe so. But politics weren't much
rarefied when Andrew Jackson was president, either. The larger problem
with blogs, it seems to me, is quality. Most of them are pretty awful.
Many, even some with large followings, are downright appalling.

Every conceivable belief is on the
scene, but the collective prose, by and large, is homogeneous: A tone
of careless informality prevails; posts oscillate between the uselessly
brief and the uselessly logorrheic; complexity and complication are
eschewed; the humor is cringe-making, with irony present only in its
conspicuous absence; arguments are solipsistic; writers traffic more in
pronouncement than persuasion . . .

I haven't really posted on this editorial any more than I have posted on the commercials I hear every day for FM radio telling me how bad satellite radio is, and how much I should enjoy hearing 15 minutes of commercials an hour rather than paying $30 a month in fees.  There is a consistent human behavior which tends not just to be threatened but to be outraged by upstart competitors.  Remember this story on the milk cartel  -- entrenched interests are flabbergasted that anyone would even attempt to compete with them in a new way.  New competitors are not just bad and unworthy, they are portrayed as threatening all the good things that already exist.

Now that I am started, though, here are a few other random thoughts:

  • It is inappropriate to compare single blogs to individual newspapers.  The WSJ has hundreds of reporters, while most blogs have one.  In making such a comparison, one is comparing a brain on one hand with a single brain cell on the other.  Blogs have much of their value as a network or swarm, in how the individual "cells" interact with each other and complement each other.  We might read one or two iterations of the daily fishwrap each day, but I read at least 30 blogs, all aggregated together for me in a convenient form by Google Reader.  And these thirty are augmented by links that I follow to as many as a hundred other blogs each week to learn more about individual issues.
  • I don't particularly disagree with this statement:

The blogs are not as significant
as their self-endeared curators would like to think. Journalism
requires journalists, who are at least fitfully confronting the digital
age. The bloggers, for their part, produce minimal reportage. Instead,
they ride along with the MSM like remora fish on the bellies of sharks,
picking at the scraps.

Few bloggers would disagree with this view that we depend on the reporting of the MSM for a starting point of much of what we do.  However, I would probably argue that some of the scraps we are picking up are larger than Rago would concede.  By the way, if you leave out a few papers like the NY Times, I could make the same accusation against 99% of the papers in this country, arguing that they are riding on the backs of the wire services, only doing a small percentage of their own reporting.  What's the difference?

  • One of the reasons there are so many scraps left for us blogger-remoras is that newspapers load up on people whose education and entire professional career is in writing and journalism, rather than in economics or business or law or science whatever they are writing about.  You can just see the institutional hubris in Rago's complaint quoted above about the quality of the prose and the humor, longing for real journalists who can use logorrheic and solipsistic in the same sentence (not to mention four commas, five semi-colons, one colon, and one set of ellipses).   So while newspapers load up on journalism and English majors who write lovely and witty prose, blogs are written by leading economists, legal practitioners and professors, successful business people, technology experts of every stripe, etc. etc.  No newspaper, for example, has even one tenth the economic firepower the combination of Cafe Hayek, Marginal Revolution, the Knowledge Problem, and the Mises Blog, among many others, bring to my desktop.  Ditto for Volokh / Scotusblog / Instapundit / Overlawyered / Tom Kirkendall on legal issues. [Update:  Oh, and a lot of those other bloggers are, uh, journalists]
  • One of the mistakes newspaper-types make in comparing newspapers to blogs is that they compare the reality of blogs with the ideals of newspapers, particularly on things like sourcing and fact-checking.  However, it's becoming clear that this comparison is increasingly unfair, because the reality of newspapers is diverging a fair amount from their ideals.  Of course, we all tend to fall short of our ideals.  But what is worrying about newspapers is that those who purport to be gaurdians and watchdogs of these ideals are increasingly becoming appologists for their violation.  How many times are we going to hear the "fake but accurate" response to blogger accusations of problems in MSM sourcing?
  • I will concede that the Mr. Rago's employer the WSJ is one of the few newspapers that really understand how they create value, or at least are consistent in their value story and their pricing policy.  If, as Rago and others argue, it is the reportage that is of value and editorializing is just the remora, then shouldn't it be the reporting behind the firewall and the editorials out front?  This is how the WSJ does it, but for some odd reason the NY Times does it just the opposite:  They let everyone have access for free to the output of their uniquely large and talented reporter pool, but put the confused economic rantings of Paul Krugman and Maureen Dowd behind a paid firewall.  Huh?

Advice on Growing a Blog

I have tried a bit of everything to grow my blog:  participating in carnivals, signing up for contests, spamming Glenn Reynolds for attention (sorry Glenn).  Here is the lesson I have learned:  You have just got to write a lot.  Other bloggers will notice you and start linking back to you when you write about them.  Walter Olson at Overlawyered has had me guest blog a couple of times, and I don't think I ever emailed him once.  I linked to a lot of his posts, adding my commentary, and he eventually noticed.  Ditto some of the folks at Cafe Hayek, at Reason, and at the Knowledge Problem.  In turn, I have discovered great blogs like Maggies Farm and Catallarchy from my traffic logs.  Write a lot on your blog, and comment on other people's blogs, if you really have energy to burn, and the traffic will show up.  Search engine traffic alone will bring new readers, and the more you post, the more different searches will find you (though some are a bit bizarre).

As a sort of reverse proof of this, here is my traffic profile for the last year.  Nothing spectacular, I am just a small blog, but you can see what happened to traffic when my posting went way down over the summer.  I have in turn been burning up the keyboard in September, and I hit a new traffic high.

Update: Trackbacks used to be a great way to tell folks that you were commenting on a particular post.  Unfortunately, spam has pretty much killed them at most sites, including this one. 

Asking for Conservation

Have you ever heard of government authorities making public statements around Valentine's Day to please conserve on roses since we are entering our peak demand season for them and rolling shortages could ensue?  No?  Never?  Well, the demand spike for roses on Valentines is much more dramatic than the demand spike for power on a hot summer day.  So why no urgent government messages for conservation of the former but constant ones for the latter?

Because the rose market is not heavily regulated.  Producers are free to manage their capacity without government interference, and, perhaps more importantly, producers are free to charge peak pricing in high demand periods.  In fact, prices for roses on Valentines go for a multiple of everyday pricing that a similar differential in a peak supply period at, say, a gas station would likely get the proprietor arrested for price gouging.  But we recognize that its tough to manage a business to supply all its capacity in one day of the year, and accept the higher pricing.  Why is it we can't accept the same facts of life in electrical generation, where capacity is orders of magnitude more expensive to manage than rose growing?

Supply and Demand in Gasoline

Via Lynne Keisling of the Knowledge Problem comes two good articles on supply and demand in the gasoline markets. 

The first is from James Hamilton, who analyzes the effect of gasoline price increase on demand and finds, amazingly to some I guess, that demand has fallen substantially.

Gas_demand_1

We have certainly seen this in the camping and travel business, as visitation has fallen off the map of late, though fortunately it comes right at the end of the season.  It appears that demand has fallen about 10% with the increase to circa $3 gas, about matching the shortfall in US refining capacity post-Katrina.  Does anyone doubt that we would have seen gas lines had prices not risen?

The second article is from Steve Chapman. Apparently, Democratic senators are separately working to make sure that higher oil prices are not allowed to spur either lower demand or higher supply.   First he takes on serial-stupid-statement-making Maria Cantwell who is working the demand-side with her desire to have the US President set retail gasoline prices:

This week, as gasoline prices remained above $3 a
gallon, [Maria Cantwell] proposed giving the president the power to tell retailers
what they can charge at the pump.

A lot of people grew anxious
seeing long lines forming last week, as motorists rushed to fill their
tanks in the aftermath of Hurricane Katrina. But Cantwell apparently
enjoyed the sight well enough that she'd like to make those lines a
permanent feature of the landscape. If so, she has the right approach.
The government does many things badly, but one thing it knows how to do
is create shortages through the vigorous use of price controls.

That's what it did in the oil market in 1979-80, under President Jimmy
Carter. He was replaced by Ronald Reagan, who lifted price caps on gas
and thus not only banished shortages but brought about an era of low
prices.

Cantwell thinks oil companies have manipulated the
energy market to gouge consumers, though she is awaiting evidence to
support that theory. "I just don't have the document to prove it," she
declared. Her suspicions were roused when she noticed that prices
climbed in Seattle--though most of its oil comes from Alaska, which was
not hit by a hurricane.

Maybe no one has told Cantwell that oil
trades in an international market, and that when companies and
consumers in the South can't get fuel from their usual sources, they
will buy it from other ones, even if they have to go as far as Prudhoe
Bay.

If prices rose in Dallas and didn't rise in Seattle, oil
producers would have a big incentive to ship all their supplies to
Texas--leaving Washingtonians to pay nothing for nothing. When a freeze
damages Florida's orange juice crop, does Cantwell think only
Floridians feel the pain?

Then, he turns his attention to Senator Dorgan, who wants to make sure we get no new oil supplies by having the government confiscate "windfall profits"

Sen. Byron Dorgan (D-N.D.), meanwhile, was outraged by
the thought of giant oil companies making money merely for supplying
the nation's energy needs. He claimed they will reap $80 billion in
"windfall profits" and wants the government to confiscate a large share
of that sum through a special federal tax.

But the prospect of
occasional "windfall" profits is one reason corporations are willing to
risk their money drilling wells that may turn out to be drier than Alan
Greenspan's reading list. Take them away, and investors may decide
they'd rather speculate in real estate.

Speaking of real
estate, Americans seem to feel no moral compunction about getting rich
from unforeseen increases in the price of another vital necessity. You
think home sellers in Baton Rouge haven't raised their asking prices in
the last 10 days? You think Dorgan wants to tax their windfall?

It's hard to see why oil companies shouldn't make a lot of money when
the commodity they provide is suddenly in short supply. After all, they
are vulnerable to weak profits or even losses during times of glut.
Back when Americans were enjoying abundant cheap gasoline, the joke was
that the surest way to make a small fortune in the oil industry was to
start with a large fortune.

Oil companies are also subject to
the whims of nature. No one is holding a charity fundraiser for the
businesspeople whose rigs and refineries were smashed by Katrina. No
one will come to their aid if prices drop by half.

Maybe Senator Dorgan can go back and confiscate the windfall profits that Maria Cantwell made in the Internet Bubble, where she made a fortune cashing out to later investors who took a bath.  At least oil companies are creating value with new oil production with their windfall profits:

Calgary"” Penn West Energy Trust is holding
a huge land sale -- looking to sell exploration rights to more than
500,000 hectares of undeveloped territory in Western Canada -- and the
offering has stirred a frenzy among many oil and natural gas companies
hungry for new drilling options.

"Demand is phenomenal," said Moya Little, president of Western
Divestments Inc., the firm brokering the sale. "It's a wide spectrum of
companies, startups, majors, any company that needs to drill."

And more here:

The world's biggest oil producers have significantly
boosted investment in oil exploration for the first time in nearly two
decades.

The Organisation of the Petroleum Exporting Countries,
the cartel controlling 75 per cent of the world's oil reserves, on
Monday revealed its most important members had drilled 7.5 per cent
more wells last year than in 2003 in response to the oil price boom.
Opec's annual statistical bulletin also showed that the number of rigs
in operation within the 11-member cartel rose 18.8 per cent last year
after dropping by almost 6 per cent a year earlier.

What useful purpose is Cantwell using her windfall Internet stock profits for, other than financing her own run for the Senate?  Could the Democratic Party be any more clueless about economics?  Jeez, why is it that our opposition party in this country has to be such a joke?

More on Gasoline Prices

Lynne Kiesling is on fire, with a series of posts on gasoline pricing over at the Knowledge Problem.  She has posts here and here showing how gasoline purchases have fallen steadily as a percentage of household income, and she also has a nice summary post about the recent runup in prices here.

She is now headed up to the Boundary Waters - hopefully she is camping the Boundary Waters here.

Chocolate Blogging

Lynne Kiesling of the Knowledge Problem has been blogging on just what chocolates are the best in the world (her normal beat is economics and electricity markets).  In this post, she answers my question about my wife's favorite, Maison
du Chocolat
, and how it compares to her favorites.

I am reminded of my kids' favorite Johnny Depp line from Chocolat:  "good, but not my favorite".

By the way (just to make this post totally stream of consciousness), I think it would be impossible to have Lena Olin's character in Chocolat be any different than her role as Sydney's mom in Alias.

Building Capitalism in Iraq

The Knowledge Problem makes a good point:

Why has this administration said so little publicly about the development of capitalism, not merely democracy, in Iraq? Vernon [Smith] said that it's probably because we don't know how to "build" a market, and certainly Hayek and other Austrians would agree.

If the neocons are going to argue for aggressively promoting our values while toppling totalitarian regimes, they better figure out how to do it.
