Perspective

   Posted by: Nick Soutter   in Statistics

It is a new year, and as we consider whom to vote for in this presidential election, the state of our economy, our environment, our society and culture, and the world and our place in it, let us consider some facts which may put the remarkable and unprecedented time in which we live into some perspective.

In America, the land of the free, we have 2.2 million people in prison, roughly 3.1% of our population. This is the highest percentage of any country in the world. Further, 25% of the world’s prisoners are in America, while America represents only 5% of the world’s population. China, with a population of 1 billion, more than three times our own, has only 1.5 million people in prison. Read the rest of this entry »

Racist Psychics

   Posted by: Nick Soutter   in Free Speech, Politics, Racisim, Statistics

“I do know that it’s true that if you wanted to reduce crime, you could — if that were your sole purpose — you could abort every black baby in this country, and your crime rate would go down”
Bill Bennett (09/28/05)

“We have been the cowards lobbing cruise missiles from 2,000 miles away. That’s cowardly. Staying in the airplane when it hits the building, say what you want about it, it’s not cowardly.”
Bill Maher, Politically Incorrect (09/26/01)

A few years ago I met a psychic. Skeptical at first, I was amazed by the overwhelming proof of her ability to predict the future. She had even predicted the assassination of JFK and called the White House days before his trip to Texas, warning him not to go. If only they had listened to her….

She keeps with her a clipping from a newspaper, where her ominous warning to the president was published, as were her credentials as a psychic.

Unfortunately, as impressive as her abilities are, there are a few things she fails to mention to prospective clients. First of all, the White House receives 600 calls a year from “psychics” warning the president of his impending assassination. At nearly two calls a day, a far more surprising event would be if the president was assassinated and someone hadn’t predicted it.

Secondly, she failed to mention that that particular call was the fourth she had made predicting an assassination. The previous three had all been wrong (as were the next 12 she made for future presidents). Further, as impressive as predicting the assassination was, she has not made any other successful predictions in the last 40 years.

It is true, that she accurately predicted, and even attempted to warn of, the Kennedy assassination. But that fact, without a larger context, is extremely misleading.

When Bill Bennett said that one could lower the crime rate by aborting black babies, the media went wild. How could he advocate such a position?

The truth is he didn’t. He stated a fact.

It is far easier (and more self satisfying) to adopt a position of anger and moral outrage, than it is to look at his statement in context, and see if the apparently obvious implication of the statement is in fact what he intended to say. It is a case of Attribution Error, assuming that his motives must have been racist.

A listener had called into Mr. Bennett’s show and argued that the “lost revenue from the people who have been aborted in the last 30 years” would have been enough to save Social Security.

Mr. Bennett was immediately skeptical of that statistic, and argued he did not believe it to be accurate, that it painted an incomplete picture of the economic impact of abortion. The caller claimed the statistic to be completely accurate, to which Mr. Bennett replied that it was also true “that if you wanted to reduce crime, you could — if that were your sole purpose — you could abort every black baby in this country, and your crime rate would go down.”

His point? That statistics can often only paint half the picture, that such “far-reaching, extensive extrapolations” (as he put it) were meaningless, and that to argue that abortion should be illegal as a means of saving Social Security was as ludicrous as to argue that abortion should be legal as a means of reducing crime, no matter what the statistics said. His called his own statements “ridiculous, and morally reprehensible”, which is of course why he made them.

For his comment about the 9/11 hijackers, Bill Maher was fired from ABC for being to insensitive (despite the fact that he had held an empty seat on his show for a month for conservative commentator Barbara Olson, who died when her plane hit the pentagon while she was on her way to be on his show). What was Bill Maher’s point? That it’s easy to be dismissive of the terrorists, to call them cowards and say that there is no reason that they hate us, but it isn’t the truth, and it greatly underestimates them.

I once announced to a college class that women generally have smaller brains than men, suffering a politically correct backlash that followed me for four years. Somehow I was sexist. Somehow people thought that I must mean that women aren’t as smart as men. The fact that my statement was scientifically accurate had no bearing on the fact that I was obviously sexist, that I obviously meant to say that women weren’t as smart as men. I was in fact attempting to discuss the differences between men and women, in how the hemispheres of the brain communicate through the corpus callosum.

Women do have smaller brains (if you find that offensive, talk to God, I had nothing to do with it). Why anyone thinks this implies a lower intelligence is beyond me. A five foot person has smaller organs (including the brain) than I do, but can easily be smarter. A blue whale has a significantly larger brain than I do, but it can’t calculate a 15% tip. Intelligence is measured, not by the size of the brain, but by the ratio of brain mass to body mass. This fact, which I had assumed would be obvious given the wide range of human body sizes, was not considered by the people who judged my statement, leading to the erroneous conclusion that I necessarily implied that which I hadn’t.

I have never heard of Bill Bennett. He may be a racist – I have made arguments neither for nor against that claim. His declaration was a stupid thing to say, and I can imagine a hundred better ways to prove the point he was trying to make. But this country has (likely out of boredom) concluded that he stated or implied that blacks are the cause of crime, or that they should be aborted, or that blacks are less important than whites. He implied none of those things. What he said was that statistics can, when extrapolated properly, be used to justify positions which are clearly incorrect. And he’s right.

Effective communication is the basis of civilization. It can not exist without an understanding of what one is trying to say. That understanding comes in part through the sharing of a common vocabulary, but language alone is often ineffective at conveying thoughts. As important as language is, of equal importance is learning how to listen. One can attempt to understand offensive speech without condoning it, but one can never truly object to offensive speech unless they know what was said.

Having just defended him, I do hope he’s not a racist.
