Graph of causes of death in humans by Mike Huemer

Text by Mike Huemer:

What’s killing us? I made the following graph. I include the top ten causes of death in the U.S., plus homicide and illegal drug overdoses, because the latter two are actually discussed in political discourse.

Observations:

1. The top causes of death almost never appear in political discourse or discussions of social problems. They’re almost all diseases, and there is almost no debate about what should be done about them. This is despite that they are killing vastly more people than even the most destructive of the social problems that we do talk about. (Illegal drugs account for 0.7% of the death rate; murder, about 0.6%.)

2. This is not because there is nothing to be done about the leading causes of death. Changes in diet, exercise, and other lifestyle changes can make very large differences to your risk of heart disease, cancer, and other major diseases, and this is well-known.

3. It’s also not because it’s uncontroversial what we should do about them, or because everybody already knows. The government could, for example, try to discourage tobacco smoking, alcohol use, and overeating, and encourage exercise. There are many ways this could be attempted. Perhaps the government could spend more money on trying to cure the leading diseases. There obviously are policies that could attempt to address these problems, and it would certainly not be uncontroversial which ones, if any, should be adopted. Those who support social engineering by the government might be expected to be campaigning for the government to address the things that are killing most of us.

4. Most of these leading killers are themselves mainly caused by old age. If “Old Age” were a category, it would be causing by far the majority of deaths. Again, it’s not the case that nothing could be done about this. We could be doing much more medical research on aging.

5. It’s also not that we just don’t care about diseases. *Some* diseases are treated as political issues, such that there are activists campaigning for more attention and more money to cure them. There are AIDS activists, but there aren’t any nephritis activists. There are breast cancer walks, but there aren’t any colon cancer walks.

6. Hypothesis: We don’t much care about the good of society. Refinement: Love of the social good is not the main motivation for (i) political action, and (ii) political discourse. We don’t talk about what’s good for society because we want to help our fellow humans. We talk about society because we want to align ourselves with a chosen group, to signal that alignment to others, and to tell a story about who we are. There are AIDS activists because there are people who want to express sympathy for gays, to align themselves against conservatives, and thereby to express “who they are”. There are no nephritis activists, because there’s no salient group you align yourself with (kidney disease sufferers?) by advocating for nephritis research, there’s no group you thereby align yourself *against*, and you don’t tell any story about what kind of person you are.

In conclusion, this sucks. Because we actually have real problems that require attention. If we won’t pay attention to a problem just because it kills a million people, but we need it also to invoke some ideological feeling of righteousness, then the biggest problems will continue to kill us. And by the way, the smaller problems that we actually pay attention to probably won’t be solved either, because all our ‘solutions’ will be designed to flatter us and express our ideologies, rather than to actually solve the problems.

Why Does Very Hot Water Sometimes Feel Cold?

| | No comment yet

Cold receptors primarily react to temperatures ranging from 68 to 86˚F, while warm receptors are activated between 86˚F and 104˚F. At extreme temperatures—below 60˚F and beyond 113˚F—the temperature signal is accompanied by a sensation of pain. Weirdly, researchers have discovered that at temperatures greater than 113˚F, some cold receptors can also fire.

The majority of scientists support the theory that paradoxical cold is a malfunction of the thermoreceptor system. Evidence suggests that pain receptors that respond to potentially harmful heat levels coexist on the same sensory fibers as cold thermoreceptors, says Lynette Jones, a senior research scientist at MIT. So when the nerve fiber sends a signal to the brain, it can sometimes be misinterpreted as a sensation of extreme cold. Paradoxical cold is the “strange operation of a system under unusual stimulation conditions,” she says… Read more

Disadvantages of the measures

| | No comment yet

We usually start measuring what we can measure well, and we lack motivation to try to measure what we cannot measure well. In this way, the measurement makes invisible the elements that are more difficult to measure although they could be much more relevant. This increases the risk of ignoring those other elements and even in some cases, promoting the idea that they do not exist. The death toll (number of deaths) in an accident or in a conflict can make suffering -much more difficult to measure- invisible. For example, surely 10 individuals who die burned alive in an aviation accident, as a whole, suffer much more than 100 individuals who die from concussion. But suffering is difficult to measure and attention goes to the number we can easily get. This could cause the establishment of wrong priorities… Read more

How to demonstrate sentience?

| | No comment yet

In this short piece, Manu Herrán sumarizes two sets of proposals to address the problem of sentience, three mechanisms to show if an individual feels (the resemblance, the best possible explanation and Phenomenal Puzzles) and two ways to check if a theory of sentience is correct or not.

“It is common to ask: how can sentience (the ability to feel) be demonstrated? The question has several interpretations and nuances. On the one hand, whoever asks this question may be pointing out the difficulty of making predictions and obtaining evidence; In short, the difficulty of using the scientific method in the matter of sentience. But, as this article explains, there are many things we can do to address the issue of sentience in the most scientific way possible.

The question can also refer to a specific individual: how to know if an individual feels or not ?; Or it can refer to theories about sentience: what is the correct theory? How can we prove it?”

Biases on The Horror of Suffering

| | No comment yet

One person suggests that past experience with suffering is “a reason to avoid fighting suffering. Your own experiences have biased you about how bad suffering is. It’s like someone who keeps a year of food in his basement because he had to go without food at times when he was a kid, or checking where your keys are 20 times a day because you once forgot your keys.” I replied: “Some of the life experiences that make us unique we choose to keep as intrinsic moral values, while others we disregard. If we didn’t keep any of the ‘biases’ that our development instilled in us, we might be paperclip maximizers instead. My moral biases are what make me me.”
