Decision Making

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?

Magic tricks and moral fibre

By Charles Foster

How well do you know yourself? Can you identify confidently your convictions on major moral issues? If you can, do you think you could change them in a moment, and argue robustly and with conviction for exactly the opposite position?

Most people will say, unhesitatingly, ‘very well’, ‘yes’, and ‘of course not’. They should read a recent paper by Hall, Johansson, and Strandberg. Indeed we all should.Read More »Magic tricks and moral fibre

How to be a high impact philosopher, part II

In a previous post, I discussed how, as a philosopher, one should decide on a research areas.  I suggested that one method was to work out what are potentially the biggest problems the world faces, work out what the crucial normative consideration are, and then work on those areas.  Call that the top-down method: starting with the problem, and working backwards to the actions one should take.

There’s a second method for high impact philosophy, however.  Let’s call it the bottom-up method.

  1. Begin by asking ‘which are the biggest decisions that one typically makes in life?’
  2. Then ask: ‘What are the crucial normative considerations that might affect how I should make those decisions?’
  3. Then figure out which of these crucial considerations is most likely to produce an action-relevant outcome given your marginal research time.
  4. Then work on that topic!

As in my previous post, I’ll go through each step in turn.

Don’t Give Money to Beggars

I have sometimes given money to beggars. On cold autumn days, when a homeless man has seemed to be in need of some money to buy food or a cup of coffee, I have occasionally dropped him a few coins. Those coins, I have thought, mean much more to him than they do to me, and giving is a nice thing to do. Upon reflection, however, I have come to change my mind, and now I don’t give money to beggars. Let me explain why.

On the one hand, there are the traditional, somewhat cynical, arguments that—in spite of their cynicism—carry some weight.

First, for every dollar that we give to a beggar, the more lucrative we make begging and, comparatively, the less lucrative we make working. This is bad, for we want people to work, not beg. Working is productive; begging is at best neutral and often a burden and a nuisance. Second, there is no guarantee that the beggar who receives the money will spend it in ways that increase the quality of his life. He might well spend the money on alcohol or drugs, and end up financing organized crime.

These objections carry some weight, but they are not decisive. What is decisive is the fact that if you give money to beggars, you almost certainly spend your welfare budget helping the wrong people.Read More »Don’t Give Money to Beggars

The Continuing Tragedies of Home Birth and the Rights of the Future Child

By Lach De Crespigny and Julian Savulescu

Windsor Coroner’s Court has heard that a mother died within hours of giving birth at home after a private midwife committed a horrifying catalogue of errors . According to reports, the woman had previously delivered twins by emergency caesarean section, one of which later died. Her husband said his wife was ‘brainwashed’ into having a home birth by the midwife, who insisted it was safe. The Royal College of Obstetricians and Gynaecologists advise delivery in hospital after caesarean section so that an emergency caesarean delivery can be carried out if necessary. The midwife denied trying to persuade the couple to have a home birth. However she has greater responsibilities than this; as professionals we should try to persuade women to deliver in hospital if this is a safer option. But the midwife seems to have prioritized homebirth over life itself when she reportedly stated:

“Claire had a great pregnancy, she had a really lovely spontaneous birth at home and I hope Simon in time will remember that”

On being yourself

‘I was always the life and soul of the party, flirting with everyone’, wrote Lucille Howe, in ‘Fabulous Magazine’, (22 July 2012), ‘but I wanted John to fall in love with the real, quieter me’. In the same article, Charlotte Ruhle notes how her psychotherapy helped her to recover from a broken relationship. ‘[My] friends started saying I….seemed more like my old self.‘
The media, and indeed our ordinary conversations, are awash with this sort of language. Not only are we conscious – having a sense that there is an ‘I’ that is in some sort of continuity with the ‘I’ that existed yesterday, will hopefully exist tomorrow, and to whom things happen – but we have firm convictions about the nature of the ‘I’. When it is not allowed to express itself – to ‘be itself’, we complain. Depending on our education, we say that we’re ‘out of sorts’, ‘not myself’, or ‘ontologically vertiginous’.Read More »On being yourself

Parkinson’s medication blamed for sexual offences

The medication that provides significant relief from debilitating motor disturbances in people with Parkinson’s disease appears to cause a range of psychiatric disturbances that are as distressing and difficult to treat as the motor symptoms they aim to relieve.

Parkinson’s disease is usually treated with dopamine replacement therapy (DRT). This involves daily dosing with either levodopa (a precursor to the neurotransmitter, dopamine) or dopamine agonists (such as pramipexole and ropinirole) that mimic the effects of dopamine in the brain. The aim of DRT is to reduce the effects of the loss of dopaminergic neurons in specific regions of the brain involved in controlling bodily movement. However, dopamine is also a key neurotransmitter in a range of cognitive processes from executive control and memory to motivation and bonding. It is perhaps unsurprising that many Parkinson’s patients experience adverse psychiatric and cognitive side-effects from taking large doses of dopamine every day. 

Parkinson’s patients can experience severe anxiety, depression and mania and have a higher risk of suicide. A significant minority of Parkinson’s patients treated with dopamine replacement therapy will also develop impulsive and compulsive behaviours that appear to be caused by their medication. These include pathological gambling and hypersexuality, and compulsive eating and shopping. In rare cases, patients have committed criminal offences.

Should minimally conscious patients be allowed to end their lives?

Two recent articles by neurobiologist and science writer Mo Costandi raise ethical quesions about the treatment of brain-damaged patients in the light of new research. Doctors distinguish between patients in a vegetative state, who are completely unresponsive and assumed to lack conscious awareness, and patients in a minimally conscious state, who some degree of responsiveness and are assumed to have some awareness – although it is unclear what their experiences are like and what mental abilities they have. A third category of patients are those in a “locked-in” state. These people are fully aware and awake, but paralysed and unable to communicate except through eye movements. Patients in a persistent vegetative state are highly unlikely to recover from it, and in most countries the law allows, under certain conditions, passive euthanasia for this group, for example by disconnecting a feeding tube that provides life support. But is this policy ethically defensible, and should we also allow euthanasia for patients with the other diagnoses?

Can the religious beliefs of parents justify the nonconsensual cutting of their child’s genitals?

Of faith and circumcision: Can the religious beliefs of parents justify the nonconsensual cutting of their child’s genitals?

Circumcising minors on religious grounds amounts to grievous bodily harm according to a German court ruling issued on Tuesday. AFP News reports:

The regional court in Cologne, western Germany, ruled that the “fundamental right of the child to bodily integrity outweighed the fundamental rights of the parents. The religious freedom of the parents and their right to educate their child would not be unacceptably compromised, if they were obliged to wait until the child could himself decide to be circumcised.”

Some Jewish groups are up in arms. They insist that God has “non-negotiably” required that circumcision take place on precisely the eighth day after birth; hence waiting to perform the operation until the child could consent would amount to breaking this keystone covenant with their deity. Using the force of law to delay circumcision, then, is no different from banning it outright, since a delayed circumcision is religiously meaningless.

I don’t find this argument very compelling.
