How to Lie With Statistics: Fact-Checking The Soundbites
There are lies, damn lies and statistics, and the political season means that the lines between them are frayed and worn, like an electrical cord that is almost ready to short out.
Three memes beloved of the conservative right were front-and-center this week, either during the presidential debates, the rumble between Jon Stewart and Bill O’Reilly, or both. Health care (Sandra Fluke’s birth control pills plea); gasoline prices; and average household income.
There has also been a lot of chatter about the debt.
I challenge you to look at these two charts — historical debt (data from the Treasury Department) as per capita and historical debt in deflated dollars — and then think long-and-hard about what you think you know about the debt. Remember, whenever you’re thinking about dollars across time — whether it’s movie box office receipts or taxes — it’s important to index them or deflate them. If we lived where inflation was 0 percent, we would not have to worry about this. But we don’t!

Both left and right have soundbites designed to elicit a visceral reaction from the base. Some of those were on parade in the debate between Mitt Romney and Barack Obama. A few were reprised in the O’Reilly/Stewart "Rumble" three days later.

Let’s first look at health care.
The boogeyman – or woman, as it were – to the pundits on the right is Sandra Fluke.

This is a textbook case of being able to lie (that is, misrepresent reality) with statistics. Both Romney and O’Reilly claimed that gasoline prices have doubled since Obama was sworn in. The talking point is straight from the Republican Study Committee.
Why are gas prices Obama’s fault? I don’t get this. #Rumble2012Sam Beckett
Technically, they are right. Contextually, it’s a whopper that infringes on BurgerKing’s trademark.
In third quarter 2008 — while Obama was running for president against Republican John McCain — gasoline prices almost hit $4.00 a gallon and diesel, $4.50. Then there was a dramatic plunge — one that had nothing to do with which guy was in the Oval Office and everything to do with the collapse of the world’s economy.
Moreover, drill-baby-drill isn’t the answer although it’s touted by the right. The domestic price of gas — which is a function of the world market for oil, a non-renewable resource — continues to rise even though the number of domestic oil rigs operating since December 2008 has almost tripled.
Under the president’s policies, middle-income Americans have been buried. They’re just being crushed. Middle-income Americans have seen their income come down by $4,300.
And just before the debate, he said: “Income is down some $ 4,300 dollars a family and with a median income of about $50,000 dollars that means things are really tough for the American people.”
Let’s look at household income data from the U.S. Census, both in current dollars and in 2011 (inflation-adjusted) dollars. That $50K median income has been pretty constant since 2007. From listening to Romney, you would have thought it had dropped almost 10%. But according to BLS data, it was $50,054 in 2011.
Romney & O’Reilly talked about drop in median HH income under Obama. Census data from 2000-2011: #Rumble2012 #Facts http://pic.twitter.com/Hfys9XBJKathy E Gill
Here are the absolute numbers in this chart: 2000: 41,990 – 2001: 42,228 – 2002: 42,409 2003: 43,318 2004: 44,334 2005: 46,326 2006: 48,201 2007: 50,233 2008: 50,303 2009: 49,777 2010: 49,277 2011: 50,054
Notice when the unadjusted dollars flattened? 2007. That’s the same point when adjusted dollars began to dip. What else happened in 2007? The world’s economy began to implode.
O’Reilly claimed (at approximately the 17 minute mark) that the average worker has lost $5,000 in pay since Obama took office.

Sentier Research is run by former Census staff. But they don’t explain how their conclusions differ so widely from official reports. And no one from Bloomberg or FOX or the WSJ seems to find that curious.
Moreover, for the claim for Romney and O’Reilly to be true, we need to know what they mean by “average worker.” Average = mean, not median.
Then we have corporate profits after tax – that chart moves north, unlike the wage chart: #Rumble2012 http://pic.twitter.com/aPPbRk13Kathy E Gill
In the case of Sandra Fluke and birth control, both sides engage in rhetorical excess. However, I judge that the greater excess comes from O’Reilly, Limbaugh et al who continue to deliberately misrepresent (aka a lie) her testimony to create a strawman.
On gasoline prices, this week’s award for misinformation goes to the Republican camp.
Regarding what’s going on with household income, I’m stumped. There are two very different reports coming from, ostensibly, the same dataset. I’ve seen no criticism of the Sentier Research reports. In fact, I’ve seen no analysis of their reports, just he-said stenography. But I don’t see how Sentier reaches their conclusions.
Both sides are remiss in ignoring the elephant in the room: the fact that corporate profits rebounded so quickly and rebounded to record levels. How much of that “profit after taxes” is because of Congressional loopholes? Given how rapidly profits rose in the Bush years, it does give one pause.
The truth: in the political season, it’s better hidden than a needle in a haystack.
