Hihi....
Some say its stupid, some say its not, well, judge for yourself. Here is the view of the author:
"when I put the "See Bill or John?" question to both lay and medical audiences I almost always get versions of the response, "See Bill; he's in distress now."
So why have so many people chosen Bill? The very notion of prevention is that disease either doesn't develop or is postponed so that we can live a longer, disease-free life before the inevitable mortal claim on all of us. Why shouldn't we be indifferent to curing now vs preventing (or postponing) disease in the future?
In the case of Bill and John you have as much obligation and duty to see either person. They are both existing patients who expect you to keep your promise to attend to them, to provide healthcare for them, and to help them to your best ability. Because of the construction of the thought experiment you cannot "cop out" and say you'll see Bill now because you can see John again in a week or so. Nor can you refer Bill to another physician in the area. Besides, there may very well be a threshold point beyond which trying risk reduction for heart disease will not be effective for a particular patient.
Our tendency to want to see Bill evolves from several untested but intuitive reasons. First, we have compassion for those in distress. The British philosopher David Hume talks of "sympathy" (we might today call empathy) as a contagious passion that infects human being-to-human being.
Second, instinctively there seems to be a strong intuitive desire to help those we know are likely to have imminent problems. This is similar to our tendency to be more charitable to those who are near vs distant.[3]
Third, we believe that our preventive acts are only statistical, whereas our curative acts are certain. This mistaken belief perhaps derives from our sense that we have more control over cure outcomes than prevention outcomes -- we think that we do cure, whereas we only facilitate prevention. This notion of doing vs facilitating is an important one, because if we believe that our curative actions are more effective than our preventive actions then we will more likely choose the more effective actions.
Fourth, generally we are more comfortable with the idea that our attempt to help those in current distress can be riskier than preventing future distress. The editor of the British Medical Journal , Fiona Godlee, expressed this well when she stated, "Because it is acted on healthy people, preventive medicine needs even stronger supporting evidence on benefits and harms than therapeutic interventions."[4]
These 4 reasons for preferring to choose Bill over John cannot be ignored, but I believe they are wrong. Let me show you why.
First, to Hume's sympathy. Yes, it does exist in some fashion. And we can't ignore our emotions -- what Hume called passions -- because they are a driving force in our lives. The contemporary philosopher Robert Solomon has argued that our emotions are not necessarily the disparaged whimsical, illogical entities we make them out to be but rather are carefully considered judgments:
Emotions are not the brutish, unlearned, uncultured, illogical and stupid drives that they are so often argued to be. To the contrary, they are extremely subtle, cunning, sophisticated, cultured, learned, logical and intelligent. [5]
If this is true, then our emotions should be able to have sympathy with the notion of future disease. Our cultural bias is to the contrary and so we take on Hume's unthinking sympathetic response, not Solomon's sophisticated and subtle judgmental emotion. All it would take is some training of our imagination. Think of what the impact of a future preventable disease would mean, how disease would be debilitating, harmful, and ultimately fatal. If we were to be more future-oriented there is no clear and logical reason why the future harm of disease for John should evoke any less passion than the immediate distress of Bill.
Second, in ethics literature there are solid arguments for a moral responsibility to help geographically distant individuals just as much as we should be helping closer individuals.[3,6] These logical and intuitive arguments would hold analogous effect on the time-distance of the effect of preventive measures for John as compared with our obligations to act on behalf of time-closer distressed patient such as Bill.
Third, curative/treatment medicine is as statistically oriented as prevention. When we suggest that John quit smoking or be compliant with his antihypertensives we don't know that it will have an impact on his future health. Similarly, when we prescribe nitroglycerin for Bill we don't know whether it will relieve his distress. Drugs and devices are approved for use on the basis of the statistical proof that they work for a population of individuals, not because they will work definitively on any particular individual. Genomics and proteomics may help us improve our use of curative care by targeting it specifically to individuals who are more likely to benefit. But the phrase "more likely" is apt to be with us for decades after the introduction of genomics, which will be used for targeting prevention-oriented prescriptions as well.[7]
Finally, to Godlee's assertion that acting on healthy individuals requires a higher standard of evidence on benefits and harms. She would be right about the "harms" part if she were talking about similar types of harms. But alas, she glosses over the distinctions necessary: With prevention and cure we have to separate out the timing of our actions with the timing of our effects. There are various combinations and the long-term consequences might be variable. For example, we can perform surgery on a patient that causes harm (from anesthesia, pain from tissue disruption, etc.) and benefit (removal of an infected appendix) today. Similarly, we can have benefits today and harms in the future -- ie, the higher incidence of secondary cancers following certain chemotherapy. Or, we can have harms today and benefits in the future; these are common to prevention, such as the usually minimal side effects of vaccinations or the anxiety of waiting for the results of a mammogram that detects a carcinoma in situ resulting in a complete cure.[8]
Of course, many prevention activities also have benefits that accrue almost immediately with minimal harms. Beginning a physical fitness program not only has benefits for avoiding future coronary heart disease or osteoporosis, but also produces a sense of well-being through stress reduction. Vaccinations take only a couple of weeks to a month or so until immunity is established.
So why, other than for purely altruistic brotherly reasons, should we think that John would give up his future for Bill's present? It's not clear that he would, or that he should. But that's a question for John. My choice: I'd ask the brothers to make their own decision together, because given their known outcomes from this thought experiment, I am indifferent as to whom I would see.
What do you think?
