Type "rubbish economist" into Google. Then hit "I'm Feeling Lucky"...
The INCOVENIENT TRUTH about statistics, as Al Gore would no doubt confess
if you threatened to stop him flying, is they look backwards, not forwards
- and not even quite to the present.
That's as true of last-quarter earnings as it is of GDP. You're left guessing
what today's outcome will be, right up until it becomes historic and you can
try to claim it as fact. Even "up-to-the-minute" inputs have to exclude the
very minute we're in, and corduroy-patch models like Greg
Mankiw at Harvard should know this. So too should his chum, the White House's
own Larry Summers.
Yet Summers - formerly head of Bill Clinton's Treasury and also of Harvard
University, before coming back as Obama's chief economic advisor - used a speech
on Friday to highlight a statistic that suggests he's forgotten the basics
of empirical research. (Previous gaffes already said he'd forgotten to use
sound judgment in public.) Bundling himself into blind fortune's get-away car,
he told the Peterson Institute for International Economics that it shows "the
economic free-fall has ended."
What is this killer stat? "The number of people searching for the term 'economic
depression' on Google is down to normal levels," he's quoted by Politico.com.
Hurray for Larry!

As you can see, searches for the term "economic depression" were apparently
four times their typical level coming into 2009, as Summers noted at the start
of the year.
The search-engine depression was greater still as Larry dusted off his Team
America badge ahead of last November's election. But now, "The recent shift
goes to show consumer confidence is higher," he claimed last week.
"If we were at the brink of catastrophe at the beginning of the year, we have
walked some substantial distance back from the abyss."
Now, let's forget how absurd it might be to base an economic conclusion on
the broad pattern of Google searches. Never mind that on Summers' logic, Led
Zeppelin were never so popular as in late 2007...demand for food
stamps is now in a secular bull market...and the campaign to "free
viagra" - that famous political prisoner - hasn't been this hot since 2004.
(Larry himself shows a very
erratic pattern on Google Trends, but unlike him, we guess here at BullionVault that
it doesn't mean much.)
No, the real trouble with Summers' thesis is that the data series has yet
to end.

Ooops! Just look what's crept into the data since Larry last checked and the
start of July entered Google's query results.
Yes, Summers' own comments helped push that spike higher, of course. Google
Trends confirms it on a 30-day chart. But he was only adding on Friday
to a clear new uptrend in people searching for the dread phrase. And besides,
Obama's advisor is only driving us back to the abyss himself, back to the
brink of catastrophe, if he really believes this marker counts for something.
Better leave that forced march to the Treasury and Fed instead.
