NEW QUESTIONS ABOUT WHETHER “shaken-baby syndrome” is real or not.

GALLUP: Unemployment Up To 10.3 Percent. I’ve noticed a divergence between the Gallup numbers and the “official” numbers lately. I wonder why that is? Is it seasonal adjustment, or something else? Underemployment is up to 19.7 percent.

UPDATE: Reader Andrew Hansen writes: “The BLS non-adjusted rate is 9.8%. The Gallup rate of 10.3% has a reported margin of error of 0.7%, so the 95% confidence interval for their data is 9.6% to 11.0%. No reason to think one contradicts the other, but it is a good time to remember that both sources are estimates from survey data and have a margin of error.”

POPULAR MECHANICS: The Modernization of the Muzzleloaded Rifle. “The muzzleloading rifle is the oldest firearm on earth. It has been around since the start of the 17th century, yet the past 25 years have witnessed a resurgence of interest in muzzleloaders.”

PUBLIC PENSION UPDATE: Number of $100,000 retirees skyrocket in teacher pension system. “More proof that pension costs are spiraling out of control: The number of retirees earning $100,000 or more from the California State Teachers’ Retirement System (CalSTRS) has increased dramatically since 2009, according to new data obtained by the nonprofit California Foundation for Fiscal Responsibility.”

RICK PERRY: We Blew It On Amazon. “Gov. Rick Perry, R-Texas, told The Examiner in an exclusive interview that Amazon’s decision to leave the state was a result of a wrong decision by the state comptroller, and that he will work with legislators to make sure Amazon can stay.”

If you haven’t read the book, there’s still time to start.

MICHAEL TOTTEN: The Flight Of The Intellectuals. An interview with Paul Berman. “Partly it’s sloppiness, but mostly it’s fear of discovering what they’re going to hear in the sixteenth minute. They don’t really want to take him seriously. He demands to be taken seriously, yet his admirers are precisely the types who, out of fear of the sixteenth minute, don’t wish to do so. What you discover in the sixteenth minute is that Tariq Ramadan is his grandfather’s grandson.”

Plus this: “What’s fascinating to me is how some Western intellectuals will praise this guy as a moderate when he is, at best, only half moderate, and yet at the same time they sneer at authentic Arab liberals.”

MARK STEYN: “The guy in charge of U.S. intelligence is an idiot.”

BECOMING HISTORY: The factory-installed in-dash tape deck. “It’s a little difficult nowadays to recall how revolutionary this idea of playing whatever you wanted in your car really was.”

A SURE SIGN OF CIVILIZATIONAL DECLINE? “If he lives with his parents, you might want to think twice. About buying his government’s debt.”

Plus, from the comments: “In the end, isn’t joining a currency union with Germany, more or less, the national equivalent of living with the folks?”

READER MIKE PUCKETT SENDS THIS QUOTE FROM GEORGE ORWELL:

It is a commonplace that the history of civilisation is largely the history of weapons. In particular, the connection between the discovery of gunpowder and the overthrow of feudalism by the bourgeoisie has been pointed out over and over again. And though I have no doubt exceptions can be brought forward, I think the following rule would be found generally true: that ages in which the dominant weapon is expensive or difficult to make will tend to be ages of despotism, whereas when the dominant weapon is cheap and simple, the common people have a chance. Thus, for example, tanks, battleships and bombing planes are inherently tyrannical weapons, while rifles, muskets, long-bows and hand-grenades are inherently democratic weapons. A complex weapon makes the strong stronger, while a simple weapon–so long as there is no answer to it–gives claws to the weak.

So where does Twitter fit in?
