Inferred justification: We invaded Iraq, therefore Saddam Hussein caused 9/11

According to Sharon Begley's article at Newsweek, "Lies of Mass Destruction," people are susceptible to upside down reasoning. She cites a large team of researchers who studied the people who believe the lie that Saddam Hussein caused 9/11. The researchers concluded that these believers believed that lie because the U.S. invaded Iraq. They refer to this upside-down process as "inferred justification." Begley sums it up:

Inferred justification is a sort of backward chain of reasoning. You start with something you believe strongly (the invasion of Iraq was the right move) and work backward to find support for it (Saddam was behind 9/11). "For these voters," says Hoffman, "the sheer fact that we were engaged in war led to a post-hoc search for a justification for that war."

The researchers published their findings in a paper entitled "There Must Be a Reason”: Osama, Saddam, and Inferred Justification." Here's an excerpt from Sociological Inquiry.

The primary causal agent for misperception is not the presence or absence of correct information . . . Our explanation draws on a psychological model of information processing that scholars have labeled motivated reasoning. This model envisions respondents as processing and responding to information defensively, accepting and seeking out confirming information, while ignoring, discrediting the source of, or arguing against the

substance of contrary information. Motivated reasoning is a descendant of the social psychological theory of cognitive dissonance, which posits an unconscious impulse to relieve cognitive tension when a respondent is presented with information that contradicts preexisting beliefs or preferences. Recent literature on motivated reasoning builds on cognitive dissonance theory to explain how citizens relieve cognitive dissonance: they avoid inconsistency, ignore challenging information altogether, discredit the information source, or argue substantively against the challenge. The process of substantive counterarguing is especially consequential, as the cognitive exercise of generating counterarguments often has the ironic effect of solidifying and strengthening the original opinion leading to entrenched, OSAMA, SADDAM, AND INFERRED JUSTIFICATION polarized attitudes. This confirmation bias means that people value evidence that confirms their previously held beliefs more highly than evidence that contradicts them, regardless of the source.

In her article, Begley suggests that the current health care debate stems from the same cognitive vulnerabilities.

There are legitimate, fact-based reasons to oppose health-care reform. But some of the loudest opposition is the result of confirmatory bias, cognitive dissonance, and other examples of mental processes that have gone off the rails.

We’re faster, finally.

Over the past few weeks, we've had a lot of trouble with this website running slowly. Yesterday, we figured out the source of the problem: a WordPress plug-in for "popular posts." Removing that plug-in sped up the site immensely. That is why that "popular posts" navigation feature no longer appears. In return, the site should pop up on your browsers in a second or two now, instead of 15 seconds. WordPress is a fantastic (and free) blogging platform and many of the optional plug-ins are slick, but once in a while we run into a plug-in that doesn't play nice with the platform. Bottom line, our load times should now be a lot less taxing on your patience.

Glia: That other tiny engine of thought

Quick! Name a small and numerous component in the brain that allows us to think. If you said "neuron," you would be only partially correct. According to Carl Zimmer's blog at Discover, "The Loom," evidence is accumulating that thinking is also accomplished by astrocytes

—named for their starlike rays, which reach out in all directions—are the most abundant of all glial cells and therefore the most abundant of all the cells in the brain. They are also the most mysterious. A single astrocyte can wrap its rays around more than a million synapses. Astrocytes also fuse to each other, building channels through which molecules can shuttle from cell to cell.
To put glia into a broader perspective, consider Zimmer's introduction to his post on glia:

I’ve asked around for a good estimate of how many neurons are in the human brain. Ten billion–100 billion–something like that, is the typical answer I get. But there are actually a trillion other cells in the brain. They’re known as glia, which is Latin for glue–which gives you an idea of how little scientists have thought of them.

It has now been shown that astrocytes can sense incoming signals, respond with calcium waves, and produce outputs

In other words, they have at least some of the requirements for processing information the way neurons do. Alfonso Araque, a neuroscientist at the Cajal Institute in Spain . . . find that two different stimulus signals can produce two different patterns of calcium waves (that is, two different responses) in an astrocyte. When they gave astrocytes both signals at once, the waves they produced in the cells was not just the sum of the two patterns. Instead, the astrocytes produced an entirely new pattern in response. That’s what neurons—and computers, for that matter—do. If astrocytes really do process information, that would be a major addition to the brain’s computing power . . . neuroscientist Andrew Koob suggests that conversations among astrocytes may be responsible for “our creative and imaginative existence as human beings.”

Hitler and the Dining Room Table

I like Barney Frank. He says what he feels, usually in a way that makes his argument better. But it's almost a no-brainer to do a comeback on the idiocy with which he was faced in Dartmouth, Massachussetts this past week. I mean, what do you say to someone who thinks it's a valid statement to compare Obama to Hitler? A woman carrying a poster with Obama's image modified with a Hitlerian mustache stepped up to the microphone to ask why Frank supports a Nazi policy. There are so many things wrong with this it boggles the mind where to begin. Frank's response was probably the most effective. "On what planet do you spend most of your time?" he asked. Then: "Ma'am, trying to have a conversation with you would be like trying to argue with a dining room table." He then commented that her freedom to carry that poster and make such lamebrained statements was a tribute to the First Amendment and Freedom of Speech. I salute his restraint. To compare any president of the United States to Hitler is a stretch, even with the likes of Obama's predecessor. (I might consider it for Cheney, but even he does not match the level of malignancy achieved by Adolph, nor does our system allow for such people to act with unrestrained impunity, hard as that might be for some to accept.) But to compare Barack Obama to the man man of the 20th Century is such a profoundly ignorant mischaracterization that it is tempting to write off this whole experiment in potential civilization as a failure. Where does this shit come from? The Republican Party, what is left of it, is grasping at straws, sinking in the quicksand of its own inanity. We must take care to not be pulled into the quagmire in some misguided attempt to rescue it through well-intentioned but doomed bipartisan sentiments. The Republican Party has devolved into a nasty cadre of ideologues, a shrinking room of hydrophobic screechers who claw and scratch at anyone who tries to do this country a service by bringing it back to some semblance of decency. They have fed on their own conspiracy-fevered viscera for so long that they cannot even hear the words much less the sentences of opposing viewpoints. We should perhaps let them sink and drown. It would be a kindness. The fear-mongering is reminiscent of everything we've seen since 2000. Rachel Maddow, who is one of the most able of contemporary analysts on television, shows the process and the connections here. Shouting, screaming, inane blather---noise filling the spaces in which rational discourse might take place if only the decibel level could be reduced. Platitudes, sloganeering, slander, and lies are flooding these so-called town hall meetings and shoving aside reason and discovery and thought. These are not people who are interested in understanding anything, they are people bent on stopping something they've been told---been told---they should not allow.
