What's New?

A new link in the resources for the Gambler's Fallacy to a chapter from Colin Bruce's recent book, Conned Again, Watson!, which is a collection of Sherlock Holmes stories based on errors and paradoxes in probability, game theory, and economics. It may sound like an improbable and weighty mix, but Bruce has a knack for explaining these topics in an entertaining way. This book is especially focused on reasoning about probabilities, which are notoriously counter-intuitive. Also, Holmes fans should be delighted that Bruce is able to capture the feel of a genuine Sir Arthur Conan Doyle story.

Post Hoc, Deja Vu

Spinsanity's Brendan Nyhan has an article with all the particulars on the recent spate of post hoc arguments blaming the falling stock market on President Bush's speeches. This trend was criticized earlier by Howard Kurtz, as noted in two previous posts.

Update (5/28/2016): Unfortunately, this article appears to be no longer available.

Name that Fallacy

On Tuesday, Washington Post media critic Howard Kurtz described a common fallacy in reporting on the stock market:

"George Bush got blamed when the market swooned after his last speech. Should he get the credit for yesterday's remarkable rebound?

"Of course, the Dow was down 280 points when the prez spoke about corporate corruption and kept sliding until the loss hit 439 points, before boomeranging for a total loss of a mere 45. Hard to call that a Bush Bounce.

"The whole exercise is, frankly, ridiculous. Mere presidential words can't impact Wall Street prices all that much (unless he's either resigning or declaring war). This whole idea of tying a presidential speech to the red arrows that now seem a staple in the lower-right-hand corner of the cable networks is a visual trick, an imagined bit of cause and effect that doesn't exist.

"Read our lips. Markets go up and down because millions of investors make minute-by-minute decisions about the value of stocks. Period. Those decisions are affected by all sorts of things—corporate scandals, inflation, interest rates, profit projections, mob psychology, indigestion—but not because of some Washington speech."

Name that Fallacy!

Blurb Watch

Friday's New York Times carried an ad for the new movie Mr. Deeds which has the following blurb at the top:

Adam Sandler is sweet, touching and very funny."

While Toscano did write the second sentence quoted, the basis for the first sentence of the blurb is actually the last sentence of the review: "It's quite possibly the funniest film so far this summer." Of course, being possibly the funniest film so far this summer is not at all the same thing as being the funniest film of the summer! Will anyone actually waste $8 because of this quote taken out of context? Apparently, the ad writer is hoping so.

Innocence by Association

The recent book Lying About Hitler: History, Holocaust, and the David Irving Trial, by Richard J. Evans—a report on a libel trial in England brought by a Holocaust denier—has the following interesting example:

"In the welter of argument and counterargument, many of the journalists who attended the trial found themselves more and more at sea, and it was perhaps not surprising that newspaper interest dropped off once the trial got into the meat of the allegations. Listening to it all, the writer Dan Jacobson found himself feeling 'as if I were sitting in a kind of grim version of Wonderland…a region of illogicality and topsy-turvy-dom.' At times even the defense counsel Richard Rampton QC thought the same. When Irving spent some time trying to show that well-known British politicians and authors of the interwar period such as John Buchan had made antisemitic remarks, Rampton exclaimed [to the judge]:
'My Lord, this is a kind of insanity. I feel as though I was in one of Lewis Carroll's books. Mr. Irving brought this action in respect of words published by my clients. The only defence is that what is said is true, amongst them that Mr. Irving is an antisemite. What can it matter that there may have been some author from the distant past…who also, on occasion, might have made a remark as an antisemite?'" (p. 194)

The fallacy that Rampton is complaining about is a sort of reverse version of Guilt by Association: Irving seems to have been arguing that since Buchan had made antisemitic remarks, it must be okay for Irving to do so as well. This is an attempt to make an idea look better by associating it with respectable people, whereas Guilt by Association is the attempt to make an idea look worse by associating it with disreputable people.

In general, Evans' book is a worthwhile case study of slanted historical writing.
