The folly of forensics: lessons from my egg roll.

If you made it all the way through my very long Skeptic article on the criminal-justice system, you know that eyewitness identificationsonce viewed as the gold standard of guilt in criminal cases, especially rapesare now being revealed as the shaky evidentiary tool that law-enforcement officials always privately knew them to be. In fully 75% of the DNA-based exonerations wrought by the Innocence Project, there had been a positive ID at trial.

Tonight I got a lesson from my egg roll in why so-called "forensics science" should probably be the next to go out the window.


Some background. Sunday night after dinner I swept and vacuumed, and this morning my wife and I were both out of the house early without eating breakfast. In other words, nothing took place on the kitchen table all day until dinner. I was the first to arrive home, and in fact, when I walked into the house at about 4:
30, with the sun streaming through the blinds and across the hardwood floors of the dining room and kitchen, I remember being pleased at how sleek and spotless the rooms looked; like a nice photo from one of those "modern home" magazines. Anyway, my wife arrived moments later with Chinese food. As I set out plates, she placed the bag containing the food on one end of the long dining-room table, the end where we always sit. All of the food was removed on that side of the table, a good six feet from the table's other end, where no one sat. Since she'd also brought glasses and drinks to the table after setting the food down, and I'd brought napkins, neither of us found it necessary to get up for anything from the moment the bag was opened until the moment the meal was finished. What's more, the air conditioning was on, which means the windows were closed, which means there were no breezes to deal with.

And yet when I got up to put the plates in the sink a half-hour later, the first thing I noticed was a spray of crumbs at the far end of the table, beneath a chair upon which no one had sat. I went over to check it out. They were tiny pieces of an egg roll.

My point? How many episodes of 48 Hours or Dateline have you watched where a defendant was convicted based on testimony that sought to reconstruct the crime scene and thereby explain why the crime could've only happened a certain way? (That is, when a defendant isn't convicted because jurors "didn't like his demeanor at trial" or similar peripheral nonsense.) How many times have you heard "expert" testimony explaining why blood found in a certain place, or in a certain pattern, had to mean such-and-such?

My kitchen was not a crime scene tonight, thankfully. And yet I can guarantee you that a forensics expert who came to the house to "reconstruct" our dinner would've stated with certainty that someone ate at the far end of the table. "Otherwise," he or she might pose, rhetorically and with a knowing smirk, "how did those crumbs get there? Did they just walk across the floor to the place where they came to rest?"

Things happen all the time that no one can explain. You are positive, absolutely positive, that you left your keys on the counter...but you find them under the sofa cushion. There is no reason for them to be under the sofa cushion; you weren't even on the sofa! But there they are. You shrug off those puzzling episodes because they're inconsequential in the larger scheme of things. Then one day you're arrested for something and suddenly cops and criminologists are finding all sorts of ominous, incriminating significance in life's inexplicable little mysteries.

I find it frightening.

My Secret confession.

A regular reader, Case, gently chastises me as follows: "Since The Secret crowd was on Oprah last week, I've been waiting for a SHAM post on the topic." He also observes, "Isn't The Secret the anti-determinism?", and, helpfully, "FYI, the movie is now free on the web at [ this site ] that aggregates YouTube videos." Case...you got me dead to rights. The last few weeks have been crazed, so rather than watch Oprah's Secret -fest live (which I'm not sure I could've stomached anyway; I'd need several stiff drinks, and I can't start that early in the day), I TiVo'd it for later replay. Alas, the gods of technology decided to have a little fun with me: It didn't "take," for whatever reason. Maybe the Secretmeisters, in their state of profound cosmic contempt for me and my ilk, managed to dispatch some sort of curse into the ethers, and it later came to rest in my video equipment. Or maybe it's a "law of ...

Election afermath: Score one for The Secret.

What a lot of people miss about the New Age is that in philosophy and tone, it is very much aligned with latter-day conservatism and the sorts of things we saw happening, say, at AIG and Goldman-Sachs before the f all. The Secret , after all, is nothing if not wildly, irredeemably, unapologetically aspirational. Along with its philosophical sibling movements in the megachurches — such as that run by our friend Joel ("the gospel according to Vera Wang") Osteen — The Secret legitimizes the idea of endless upward mobility and a reality in which wealth is not zero-sum, but in fac t can be attained by everyone everywhere at the same time if "you just want it enough." Secret alum Lisa Nichols says it flat-out in the very title of her CD: " You Deserve It !" In the world according to Rhonda Byrne and her (pseudo-)philosophical protégés, every man (and woman) is an island, and all of those islands are the Caymans . Both The Secret and cons ervatism encourage a...

'The Only Self-Help Book You'll Ever Need—The Sequel.' By Rhonda Byrne.

Let's start, boys and girls, with a disclaimer/confession: I have not read Rhonda Byrne 's new book, The Pow-errrrr . (And can't you imagine the phrase being uttered just that way, in breathy tones that drip with a practiced air of mysterioso? The Pow-errrrr ... One almost hears distant nighttime thunder and gusty winds rustling through trees in the background. Whooooossshhhhh ....) That said, I ask you to read her publisher's own product description, as appearing on Amazon, and experience for yourself the utter contempt for the collective intelligence of her target market: The Secret revealed the law of attraction. Now Rhonda Byrne reveals the greatest power in the universe— The Power to have anything you want. In this book you will come to understand that all it takes is just one thing to change your relationships, money, health, happiness, career, and your entire life. Every discovery, invention, and human creation comes from The Power . Perfect health, incredible ...
