What is the chance of an MP being wrong?

When MPs took a maths exam it showed that the members of parliament are pretty bad at elementary probability. When asked “if you spin a coin twice, what is the probability of getting two heads?” 47% of conservatives and 77% of the Labour MPs gave the wrong answer. About 75% of the MPs felt confident when dealing with numbers, although they generally though politicians did not use official statistics and figures correctly when talking policy.

How should a rational person react to this news?

Dangerous Doctors and Immoral Doctors

In general, if you know someone to be a danger to others you have a duty to do something about it. Exactly what you are obliged to do depends on the person, the situation and you. At the very least you ought to warn others.

In general, and apart from such basic duties as not to interfere with others (more pompously, to respect their autonomy), to keep your promises to them, not to harm them and not to burden them, your strongest duties are those you take on voluntarily, such as those you acquire by taking up a profession.

The professions hold themselves out to us as entitled to special privileges because of their special knowledge. We trust them, we rely on them, we place ourselves in their hands for specific purposes, because when paid for their work they promise to look after our interest before their own. Part of that promise is a special duty to hold members of the profession accountable to professional standards and to exclude persons who fail those standards.

So members of the medical profession have both a very strong duty and a special duty to protect us from dangerous doctors. A book has come out showing that doctors are grossly— indeed, grotesquely —derelict in this duty.Read More »Dangerous Doctors and Immoral Doctors

Spin city: why improving collective epistemology matters

The gene for internet addiction has been found! Well, actually it turns out that 27% of internet addicts have the genetic variant, compared to 17% of non-addicts. The Encode project has overturned the theory of ‘junk DNA‘! Well, actually we already knew that that DNA was doing things long before, and the definition of ‘function’ used is iffy. Alzheimer’s disease is a new ‘type 3 diabetes‘! Except that no diabetes researchers believe it. Sensationalist reporting of science is everywhere, distorting public understanding of what science has discovered and its relative importance. If media ought to try to give a full picture of the situation, they seem to be failing.

But before we start blaming science journalists, maybe we should look sharply at the scientists. A new study shows that 47% of press releases about controlled trials contained spin, emphasizing the beneficial effect of the experimental treatment. This carried over to subsequent news stories, often copying the original spin. Maybe we could try blaming university press officers, but the study found spin in 41% of the abstracts of the papers too, typically overestimating the benefit of the intervention or downplaying risks. The only way of actually finding out the real story is to read the content of the paper, something requiring a bit of skill – and quite often paying for access.

Who to blame, and what to do about it?

Lie detectors and epistemic duty

The British government is about to introduce compulsory lie detector tests for sex offenders released on parole.   The British police want to use lie detectors in the detection of crime. Is this the right thing to do?

The answer to that question depends on a complex set of duties. Obviously it is highly desirable to prevent people on parole committing crimes. Equally obviously it is highly desirable to catch criminals (only when the laws are just, of course). For this reason we are tempted to latch onto anything that promises improvements. The government and the pilot study they are basing their proposal on are promising us improvements by using lie detectors. Others elsewhere have considered whether lie detectors do in fact offer better outcomes .  Even if lie detectors do offer better outcomes, which they might do whether or not they are good at detecting lies, that still wouldn’t make it right to use them.

A highly significant duty that bears on the question is the epistemic duty borne by the law and by the police, the epistemic duty to know the truth of guilt and innocence. Here I am concerned only with that duty. I do not consider other duties, such as protection from harm, that might be served by deterrent effects achieved independently of knowing the truth.Read More »Lie detectors and epistemic duty

Honesty and Science

Honesty is a virtue. The strange thing about honesty is that we do not seem to see even the simplest aspect, telling the truth when it is owed, as a duty. People who would be horrified at hurting anyone will trim, twist, exaggerate and lie at the drop of a hat, especially when it advances their ideological agenda, and will not feel they have done much wrong at all. Worse, they will anathematise those who utter inconvenient truth and feel highly righteous in doing so.

Science can be pure enquiry but the questions it seeks to answer are often those with significant practical import. The reason we subsidise science is because of the benefits it promises. Getting the benefits depends on scientists finding out and telling us the truth. From this point of view, then, honesty is a prime virtue of science and to be honest is a stringent duty owed to us all by scientists. It is unclear to what extent scientists feel properly bound by this duty.Read More »Honesty and Science

Shutting people up

You will no doubt recall that some time ago I was bewailing the backwardness of Britain when it comes to shutting people up who disagree with me. I think the case in point was in Austria, where the authorities were prosecuting a woman for criticising Islam. Never happens here, alas! Our betters in the European Union have continued to show us the way. More recently we have the prosecution of the Danish historian Lars Hedegaard for claiming that Muslim women are subjected to sexual violence.

Just give me the Humbug

We’ve all had fun hating Goldman Sachs again after one of their own sold them out . Mr Smith says that ‘culture was the secret sauce that made [Goldman] great and allowed us to earn our clients’ trust for 143 years’ whereas now Goldman pursues its own interest rather than its clients’ due to a ‘decline in the firm’s moral fibre’…. Hold on. Yes, I know its hard not to burst out laughing.

The Fragility of Freedom of Speech

It is no doubt naïve of me, but I am shocked that so many people do not believe in the freedom of speech. Without freedom of speech we have no freedom of thought and without freedom of thought we do not have ourselves. There is nothing original in this simple point. It has been a foundation of English liberty for centuries.

Freedom of speech is either the freedom to say things that others find detestable or it is no freedom at all. And this freedom imposes an equally stringent duty. We are all obliged to tolerate the expression of what we find detestable.

153 years ago Mill diagnosed brilliantly the intemperate discussion that has recently been on florid display. “Unmeasured vituperation employed on the side of the prevailing opinion, really does deter people from professing contrary opinions, and from listening to those who profess them….The worst offence of this kind which can be committed by a polemic, is to stigmatize those who hold the contrary opinion as bad and immoral men. To calumny of this sort, those who hold any unpopular opinion are peculiarly exposed, because they are in general few and uninfluential, and nobody but themselves feels much interest in seeing justice done them”. Plainly this is exactly what we have just seen.

Where, then,  is the line of toleration?

On the summary execution of murderous tyrants and the good of a timely accounting.

Despite my dislike of capital punishment I find it hard to object to the summary execution of murderous tyrants such as Gaddafi. A short period of terror followed by a swift ignominious death is much less than they deserve. What they deserve are the torments of hell. Nor is the absence of a trial an injustice done them—what doubt have we of their guilt? If they are a focus for forces intent on reviving their tyranny, and those forces will dissipate or fail without them, killing them may also be a benefit and even a necessity. So if there is anything wrong in their summary execution it must be found elsewhere and must outweigh the risks of keeping them alive. It seems to me there is something to be said on this other side and it is to be found in the good of a timely accounting.
