Studies Show

Studies show.  How many fraudulent arguments and political pieties begin with that statement?  Milk produces phlegm, Gluten causes inflammation, calories don't count, Obama caused the recession, money trickles down from the "job creators"  human activities don't affect the climate.  No matter how many large, double-blind studies are published in peer-reviewed journals, these flawed "Studies" many of which are speculations and fabrications or selected anecdotes persist.

Nobel laureate psychologist and Economist  Daniel Kahneman's book Thinking Fast and Slow posits that we have two ways of making decisions: fast and slow as you might suspect from the title, or as he calls them: system 1 and system 2.  Reading it might just cause you to reevaluate a lot of  things you've been led to believe because people who want to enlist your support, sell you their products, receive your donations and secure your votes make skillful  use of this knowledge.

We have statistics thrown at us every day and we make decisions based on our statistical illiteracy, our intellectual laziness and the tendency to make decisions based on limited facts and wishful thinking.  So much of Kahneman's work applies to how we choose investments, but it applies to virtually everything we prefer to approach with the unreliable "system 1" rather than to wade rigorously through volumes of data until our heads hurt. In a large part, "studies show" is enough for most of us.  there's always a study, an authority, a  book and it's usually enough. We prefer to judge, to evaluate on limited evidence and we prefer intuition over analysis and when we believe something to be true, whether it's because we identify with a party or an organized faith or an ethnic group, we are

"very likely to believe arguments that appear to support it, even when these arguments are unsound.  If system 1 is involved, the conclusion comes first and the arguments follow."

That doesn't sound very profound or startling and yet we virtually always fail to detect such tendencies in ourselves, perhaps more so when we think we are highly intelligent.  As Sheldon on the Big Bang Theory says "If I were wrong, don't you think I'd know it?

We tend to disallow legitimate science and valid statistical conclusions out of hand if we are engaged in politics that argue to the contrary and apparently intelligence has less than enough to do with it. The difference between that quoted statement of the obvious and the body of work summarized in the book is an enormous amount of documented science.  ( I'll mention the Nobel prize once again.)

But this is not a book review and what I'm getting at is not another Lefty attempt to show the shoddy thinking and fallacy filled folly of the Right Wing. I'm making a case for divorce.  I'm just not getting the kind of liberal thinking out of the Democratic party I need.  I feel neglected and betrayed, ignored and saddened at the endlessly tainted logic, the misused statistics and conclusions supported by faith and gerrymandered facts. I want a divorce. Let me explain.

I got an appeal yesterday, to rethink my position on the legal modifications to prior self defense laws the press likes to call "stand your ground."  Places that have such laws have more murders, states the pleading, and not just more murders but more murders of  African Americans because non-African Americans tend to see dark skinned people as hostile and dangerous and likely to be carrying weapons. But don't take their word for it and you guessed it: studies show.

It so happens that I took part in the cited study which consisted of  pressing a key with either the right or left hand  to show whether the small black and white images of human eyes belonged to white or black people. Small images were also displayed which included items like crossbows and maces.  Delays in pushing either key determined whether or not I was a racist and wouldn't you know it -- am a racist.  The study shows  and never mind the various possible reasons for time delays. Never mind any other study.

The problem from my standpoint is that it was impossible for me to determine the 'race' of well more than half of the eyes much less analyze the emotion  and there was a greater delay in pushing the key when I had that problem.  The delay is said to be proof that I associated black people with weapons and hostility, albeit mostly medieval weapons.  Seriously, but none the less, studies show. 

Now from this study, taken to be conclusive and irrefutably so, comes the leap of fallacy that I cannot be trusted to determine whether or not someone is a threat to my life because I'm a racist and by extension, no other whit person can be trusted because white people are racists. I would expect Liberals to gasp and perhaps to gag, but Democrats don't.  Democrats cling to this conclusion because studies show it's safer for to require me to run away from the attacker with a gun, white or black, and because they're Democrats after all. The conclusion comes first and the arguments follow.

Back when the Feds finally killed the 55mph speed limit, there were impassioned arguments from self-styled liberals like Alan Dershowitz telling us that there would be a bloodbath and indeed for a very short time there was a slight increase of highway fatalities. It was a statistical blip and those fatalities have continued to decline. Dershowitz made the mistake of taking statistically irrelevant data as proof of a trend -- of ignoring, as most of us do, regression to the mean and of choosing facts to fit the prior conclusion .

So my first reaction to the "states with SYG laws have more. . ." statement was the question: did they have more beforehand? and has the alleged increase been long enough to have statistical significance?  Will Regression to the Mean make this increase go away?  Without answering that question I'm supposed to hear Studies Show and jump on the bandwagon.  Sorry, I can't and because it's nearly universal in political advertising to play games with statistics, I have to side with Dr. Kahneman again when he explains that a few facts and a plausible story tend to trump informed and rational conclusion. WYSIATI he calls the gambit: "what you see is all there is" and we're all prone, in our laziness and longing to belong, to fall for it. If we fear guns we won't ask questions.  If we are invested in guns and gun rights, the opposite is true. First comes the conclusion.

The problem with interpreting statistics isn't just the pervasive ignorance of statistical method, the confusion between context and causality, but the laziness we're encouraged to cultivate in our consumer society. The vast majority of educated people will read the syllogism:

All roses are flowersSome flowers fade quicklyTherefore some roses fade quickly.

says Kahneman and agree, but of course it's not true, because it's possible that there are no roses among the some flowers that fade quickly, but my head hurts when doing the work needed to analyze it. It looks plausible,  the statements before "therefore" are true even if they are not the only facts that need to be considered and therefore we settle for "it's true" and will defend any argument based on it's truth. What with our liberal backgrounds, it's easier to agree that all white people are racists and defend policies based on it than to question Liberal authority. Easier to explain gender differences on society than on science and therefore it's fine to suppress data and prevent studies which might show. the studies that agree with us are always right.

Because it gets cold outside and insulation is necessary to sustain life, no one should interfere with our right to own warm clothing.

Does that mean that we're not allowed to own a coat in Key West but only where it gets cold? You know what I'm getting at here. Context means more than what's actually said. We see what we want to see, believe what we're disposed to believe.  We're not afraid of mittens, but still we think we're rational. We think we're guided by science and are objective, independent thinkers.  If I am actually to be all that, can I still be a Democrat?  Can I still be a Democrat if than now means I can't trust anyone in any way, that heresy is everywhere and the job of Democrats is to root it all out and punish it  even if we have to cut a swath through truth, science and  humanist values to bring the unbelievers to the stake?  No, I think I need a divorce.

Campaign logic

Argumentum ad ignorentiam: "appeal to ignorance" (where "ignorance" stands for: "lack of evidence to the contrary") Argument from ignorance may be used as a rationalization by a person who realizes that he has no reason for holding the belief that he does.

Argumentum ad Obaminem: special case of above or appeal to ignorance (where "ignorance" stands for: " all evidence to the contrary") May be used as a rationalization for libel or slander or accusation without evidence or most commonly: strongly contrary to all evidence or logic. An argument from authority in the absence of authority. Used frequently by Republican propagandists.

Argumentum ad Republican: A special pleading. It's only radical when Liberals like it or conversely: that argument doesn't apply to Republicans.

orget the Superbowl commercials or the half-time show. Forget football. The most entertaining event of Superbowl Sunday was Newt Gingrich trying to convince his audience that Barack Obama is at war with the Catholic Church. Parroting the sentiment that a secular government refusing to bow to ecclesiastical pressure as the secular constitution demands, is a declaration of war, Newt, Gingrich, appearing on NBC’s Meet the Press, Sunday, said the decision represented
“a radical Obama administration imposing secular rules on religion.”

Well I hate to bring it up, lest anyone esteem me to be needlessly argumentative, but all religious people and their organizations have always been subject to the secular law of the land and by constitutional law, none of us can be held to any religious restrictions, taboos or responsibilities by the government. You see, that's why we don't have laws about blasphemy and punishment for heretics. That's why we're not held to the Biblical command against eating Cheeseburgers or chitterlings or watching football on Sunday - or divorce which of course Newt knows as well -- just as we know by all evidence that Newt is the consummate opportunist and a veritable prince of duplicity.

Yes, of course people are very protective of their beliefs and rituals and practices and in our country as well as in most of the civilized world, they are allowed to be and protected in that right but that's only because there are no official religious laws and no special protection for church policies that do not comply with our secular laws and our rights and our protection from faith-based tyranny. Newt is following in the muddy footprints of those who continually argue against the religious neutrality and secular nature of our Republic in spite of all evidence and despite the law itself.

Please forgive me for stating the obvious and writing as if for a child, but we're talking about Newt Gingrich here and I may be talking to some who do indeed think the government should indeed take such a dim view of our personal liberty as to allow clergymen to deny us birth control or having music on Sunday or divorce or living where and with whom we please. In many places they did after all get away with that for years.

We're talking about Newt Gingrich here who, after playing with several religions in his effort to bed many women including his own high school teacher, presumes not only to speak for but to dictate Church dogma to Roman Catholics who in very large part do not agree with it.
"Every time you turn around secular government is closing in on and shrinking the rights of religious America,”
Said Newt -- who has turned around about 200 years too late. The right of "Religious America" to be the law of the land by diktat was eliminated by the first Amendment, if the rage against such tyranny by the Founding Fathers wasn't already enough to put a stop to it.

In fact, 98% -- nearly all American Catholic women who have sex have used "forbidden" birth control methods and a solid majority think the Church policy is wrong. I don't think they're going to back this flim-flam Lothario who while indulging in it himself, tried to impeach a president for extra-marital fellatio in any bid to have Washington embargo the local drug store in the name of religious "freedom." Not any more than they would have the government outlaw the kind of bed hopping, marital leapfrogging Gingrich is noted for even if they frown on it. Don't we wonder why Newt thinks Catholics are so damn stupid that they won't notice he's arguing both sides of the question?

Organized religion is about many things, but personal choice and freedom of thought has never been thought of highly, to say the least, by any of them. To have to explain to someone with a Doctorate and a writer of history books, something a slow schoolboy should know, that professed belief or membership in some religious group does not convey legal authority in the US is laughable, but of course Newt knows it. He knows a principle and constitutional law that's been around since our beginning isn't radical and it isn't about Obama. He knows he's a lair even if he doesn't know he's a disgrace. I think the voters know too.
