| Top ten reasons giving birth sounds more fun than having a migraine10. Epidurals work very reliably and
consistently; NSAIDs don't.
9. They both last about a day, but
labor pains don't come back a week later.
8. Labor pains generally don't come
with an aura of visual hallucinations.
7. We actually know what causes labor
pains, and we can treat them based on this knowledge.
6 You won't ever just start giving
birth one day for no apparent reason.
5. You will never have recurrent
chronic labor pains on a daily basis.
4. No one will ever blame your labor
pains on stress or depression.
3. No one will ever doubt that your
labor pains are genuine.
2. Most workplaces offer maternity
leave; what accommodations are offered to people with migraine?
1. At the end of labor, you get
something really cool: A baby.
Maybe labor hurts more, I don't know.
But for all these reasons, I think women need to stop complaining
about labor, especially to those of us who suffer from migraines.

| A scientifically sound sabermetrics Forget batting average. Forget saves
and no-decisions. Don't make up meaningless sums like "on-base
plus slugging" or "walks plus hits per inning pitched." (By the way, report an error margin and ignore statistically insignificant differences.)
Think instead about the fundamentals of
baseball. What does each position do? Batters get bases and try not
to get out. Fielders get outs and try not to get errors. Pitchers get
outs and try not to give bases. There are only certain things each
player can do, so don't hold each one responsible for the whole team.
So, we should rate in the following
way:
Batters: Bases earned per opportunity,
call it BEPO.
This would be calculated based on
current statistics as:
BEPO = (singles + 2*doubles + 3*triples
+ 4*home runs + walks + hit-by-pitch bases + stolen bases)/(at-bats + walks +
hit-by-pitch bases)
Fielders: Errors per out, call it EPO.
(Obviously you want to minimize this.)
Straightforward to calculate:
EPO = (errors)/(outs)
Pitchers: Bases given per out, call it
BGPO. (Again, you want to minimize this.)
This would be calculated as:
BGPO = (singles + 2*doubles + 3*triples
+ 4*home runs + walks + hit-by-pitch bases)/(outs + other-player
errors)
[The other-player errors are included
so that pitchers aren't held responsible for fielders' mistakes.]
Unfortunately, most statistical
resports don't give out separate scores for singles, doubles, and
triples (just "hits" and "home runs"), so it's
hard for me to give you any specific examples of what this would
mean.
I can tell you a few things, though: A
batter who has a 0.250 average but usually gets doubles and home runs
would have a high BEPO—and would be a good batter. A pitcher who
repeatedly loads the bases but manages to escape without a run scored
would have a high BGPO—and indeed, most would agree, is not a very
good pitcher. Right now, that batter would be rated poorly and that
pitcher would be rated well—and this seems wrong to me.
[Note: I added stolen bases to the BEPO score, because I realized that stolen bases are as good as any other kind of bases, and are just as good an indicator of a good batter.]

| The permissible/allowable distinction and hate speech There is a general confusion among many
liberals (I mean "liberals" in both the philosophical sense
of believing in the moral importance of personal liberty, and the
political sense of supporting policies that tend to restrict economic
freedom before social freedom) about what to do with so-called "hate
speech"—speech that advocates moral positions which are evil
and dangerous.
For a typical example, what is to be
done with neo-Nazis who claim that Jews are inferior to Whites and
deserve to be enslaved, imprisoned, or murdered? What is to be done
with fundamentalist Christians who say that homosexuals are criminals
against God and deserve to burn in eternal fire? As a less familiar
yet no less significant example, what is to be done with people who
profess something called "moral relativism" and claim that
all moral claims are meaningless, that the beliefs of Nazis or
nihilists are as sound as the beliefs of liberals or utilitarians?
This sort of speech is not the same as
direct incitement to violence—"Jews should be
killed"/"Homosexuals should burn" is not the same as
"Kill that Jew"/"Burn that homosexual"—nor is
it the same as any of the other sorts of speech liberals would
ordinarily restrict, such as irresponsible lies that directly
endanger people (e.g. yelling "Fire!" in a crowded theater
when there is no fire) or perjury in a court of law that would hinder
the process of justice. Yet clearly this sort of speech is wrong,
not just in a factual sense, but
in a moral sense as
well; hate speech constitutes a declaration of moral beliefs which
are not only false, but harmful, immoral and dangerous.
As
such, it seems (at first glance) that we ought to restrict hate
speech, make it illegal and punishable in the same way that we make
murder or theft (or, more analogously, perjury) illegal and
punishable. But then we have a system in which the government has a
right to legislate moral statements—and it seems a slippery slope
to exactly the sort of "thought police" that liberals most
fear. If hate speech is permissible, it is not immoral; but if it is
impermissible, should we not make it illegal?
The
answer lies in an important but often-neglected distinction: Between
that which is permissible—what
it is morally acceptable to do—and that which is allowable—what
good people ought not to use violence to prevent. (Attack not my
etymology, for these are technical terms; I realize that in common
usage "permit" and "allow" are close synonyms.)
Obviously,
all that is permissible is allowable—one should never use violence
to prevent acts that are not immoral!—but importantly, not all that
is allowable is permissible. There are acts which are morally wrong
(impermissible), yet which are
not so wrong that it is justified to use violence to prevent them.
\[
\forall x \in P: x \in A \]
\[
\exists x \in A: x \notin P \]
\[ P
\subset A \]
\[ A
\not \subset P \]
Hate
speech is precisely the sort of act which is impermissible but
allowable. Another such act is cutting in line; another is making
rude insults. I'd put public nudity in the same category, and
probably software piracy as well. Often, these are simply violations
of custom, rather than
deep moral rules; they are wrong because in these social
circumstances they violate
contractual obligations of acceptable behavior, not because they are
intrinsically harmful. Hate speech is actually a case where we might
say that the act is intrinsically harmful—but in this case, the act
is still allowable because the cure would be worse than the disease.
What,
then, is the proper response to hate speech? More speech! Answer
these hateful and atrocious lies with truths, and sound arguments to
defend those truths. Minimize the harm now, and attempt to persuade
others not to say these words. But remember always that these words,
however wrong, are allowable—you
have no right to use violence or legal punishment in order to stop
them. You need not hold your tongue—indeed, you ought not
hold your tongue—but leave laws and guns out of the matter.
Thus,
Richard Dawkins' God Delusion and
Lily Allen's Fuck You are
precisely the correct action to take, and should be applauded as
such. When a science teacher tells his student creationism is false
and superstitious nonsense,
he is doing precisely what he ought to do—and it is a travesty of
justice that this act was punished, for it is not merely allowable,
not merely permissible, but outright good, while
the creationism he attacked can only achieve the level of allowable.

| Why I oppose NOMAThere is a fairly large contingent of
scientists—good, respectable scientists like Stephen Jay Gould and
Niles Eldredge—who advocate a position known as "Non-Overlapping
Magisteria," usually abbreviated (somewhat strangely) as NOMA.
Essentially, this position claims that science and religion are
complementary systems, one describing one "magisterium" of
the natural world, the other describing another "magisterium"
of the supernatural world—or maybe the ethical world, since NOMA
is usually espoused by innuendo more than anything else, and I've
never heard anyone really rigorously define what the "magisteria"
are or what theories rightfully correspond to what magisteria.
Typically, these scientists object to
the statements of other scientists—also good, respectable
scientists like Richard Dawkins and Will Provine—that science is
fundamentally opposed to religion, that science is actually true
and not just "one way of
looking at things," that some opinions are better than
others, that a scientific mindset will never be compatible with a
faith-based approach to the world.
I hold this latter position—indeed, I
have trouble relating to scientists who do not. I try to; I recognize
that many respectable scientists support NOMA, scientists who
continually make scientific achievements of a degree I can barely
aspire to.
Of course, as I noted, many other
respectable scientists agree with my position as well—so I'm left
with little choice but to say that many respectable scientists are
wrong.
In fact, I increasingly find strange
scientific and philosophical errors made by scientists who support
NOMA—but I can't be sure if I am merely looking for these sorts of
errors due to my own biases against NOMA itself. (Maybe Dawkins has
made similar errors and I've ignored them?)
For instance, Niles Eldredge writes in
The Triumph of Evolution (note
2 to chapter 6): "[…] I agree with one of the letter writers,
who noted the one great gap—inherently and in principle
'bridgeable,' but not in actuality so between humans and any other
form of animal life known: the consciousness that
we humans have. As the writer of the letter pointed out, human
behavior is purposive in the sense that it is consciously pursued for
survival. […] In other words, I do not think that even the wisest
chimp knowns, and can therefore contemplate, the fact that it will
die someday."
This
seems to imply that Eldredge agrees with Descartes that all animals
other than humans are unthinking automatons, without sensation,
experience, or emotion. He agrees that human beings evolved from
other animals—indeed, he argues forcefully for that conclusion—but
doesn't seem to realize that this strongly suggests consciousness is
a quantitative, not qualitative, trait—that cats and rats and bats
all have a conscious experience comparable to our own, that sharks,
octopuses and lizards probably have a simpler consciousness, but
clearly have some conscious experience, and that more ancient
organisms like worms and beetles may well have some rudimentary
consciousness as well.
When
challenged with the fact that chimpanzee behaviors show cultural
patterns of transmission, Eldredge bites the bullet in the most
absurd way imaginable: "[…] perhaps the patterns of geographic
variation in simple tool use and other aspects of chimp 'culture' do
connect on a sliding scale with human material cultural
traditions—with the further implication that consciousness itself
is not a prerequisite for the development of culture or perhaps even
cultural traditions, as exemplified in the toolmaking traditions of
the Paleolithic." I might as well say that consciousness is not
necessary to write books about evolution, and Niles Eldridge may well
be an unthinking automaton! Though no one has ever convincingly
solved the problem of other minds once and for all (has anyone ever
convincingly solved anything once
and for all?), the most plausible solution in both theory and
practice is to infer, as Alan Turing did, that structure and behavior
indistinguishable from consciousness implies consciousness. This
means that the following inferences are very probably correct: When a
dog lays lethargically over the fallen body of his mate, he is really
grieving; when a cat
stares at a ledge for a few seconds before jumping up to it, she is
really reasoning; when
a chimpanzee makes a tool in front of other chimpanzees who then
proceed to make similar tools, he is really teaching.
Consciousness is ubiquitous in
the animal domain—hardly unique to parochial Homo
sapiens. Indeed, I might even go
so far as to say that if you show me an evolutionist who is not a
vegetarian, I will show you a hypocrite.
But
even though Eldridge is clearly wrong about consciousness, this does
not imply that he is wrong about NOMA; indeed, he is clearly right
about many other things, so his credibility is scarcely tarnished by
one obvious mistake.
So I
should take a step back, try to consider NOMA on its own merits, and
attempt to discern what consequences it would have if correct.
Catchy
phrases like "Science tells you how the heavens go, religion
tells you how to go to heaven" really don't help; after all,
clearly the word "heaven" doesn't mean the same thing in
the first clause as it does in the second (if you meant "outer
space," science tells you how to go there too!), so this
statement is no more sound than "Nothing is better than total
eternal happiness, a saltine cracker is better than nothing,
therefore a saltine cracker is better than eternal happiness."
So
let's take NOMA to be the proposition that science tells us only
about nature, not ethics, and religion tells us only about ethics,
not nature—and furthermore that nature and ethics are sufficiently
separate that views on one are orthogonal to views on the other.
This
proposition has three parts, all of which are clearly
false.
1.
Science does tell us about ethics: It informs us of the consequences
of our actions, it enhances our ability to effect changes in the
universe—including morally-significant changes. Science can tell us
what organisms are sentient and what happens when we die.
Furthermore, there are certain ethical values which are essential to
science: Honesty, openness, fairness, a commitment to resolving
dispute by reason and evidence instead of violence. These may not be
enough to define a complete ethical system by themselves (actually,
they get us pretty close!), but certainly they are ethically
significant.
2.
Religion does tell us about nature: Most religions claim that human
beings—and only human beings—have something called a "soul"
which provides consciousness, something separate from the brain. Most
religions claim that when people die, they don't really die, but
instead are transferred in some sense to a different place—either
better or worse. Nearly all religions claim that certain special
human beings can hear messages from invisible beings in the sky.
Nearly all religions claim that the laws of physics are optional, the
whims of invisible entities. These are very strong, significant
claims about nature—these are literal factual claims, and they are
completely and utterly false.
3.
Nature and ethics are not orthogonal. Many of our deepest ethical
truths depend upon truths about nature, truths that science can
demonstrate. If it were in fact true that people who die really go to
some wonderful happy place, then murder would not be immoral—I dare
say it would be good, maybe
even obligatory. It it
were in fact true that the laws of physics were optional, science
would be pointless, technology would be unreliable, and all solutions
to all the world's problems should be effected through prayer and
sacrifice to the gods. If religion's claims about nature were true,
we would not be appalled by the woman who killed her son claiming it
was God's command—on the contrary we would count her a great hero,
someone brave enough to obey God at all costs. Further, the
enterprise of science—the way we discover nature—depends upon
certain ethical principles of honesty and fairness without which it
would be impossible.
Indeed,
the pro-NOMA camp is surely wrong about something else as well: They
generally seem to think that, regardless of its false claims about
nature, religion is a good source of at least ethical and political
values (Eldredge.,
p.152): "I would no sooner place our future strictly in the
hands of scientists than I would see it placed in the hands of movie
stars—or, for that matter, lawyers and politicians. I think the
problems facing humanity at the Millennium are so great that we need
the input of all segments of society to deal with them, and here I
refer specifically to perhaps the greatest sector of society to which
one can point: the global community of organized religion."
Most
importantly, it is clear to me that organized religion is not one
community, but many communities, communities constantly vying for
power, usually through massive, genocidal violence. The history of
humanity is largely the history of war, and the history of war is
largely the history of religion. The Egyptians fought the Jews, the
Romans fought the Egyptians, the Christians fought the Romans, the
Trinitarians fought the Areans, the Christians fought the Muslims,
the Protestants fought the Catholics, the Nazis fought the Jews, the
Christians fought the Communists, now the Muslims fight the Jews and
the Hindus and the Christians. (And the Christians and the Muslims
fight the secularists, though so far with only a minimum of actual
violence.)
Religion,
unlike science, refuses to resolve debate through reason or evidence,
and so it must resolve it through violence. Religion's answer to any
question has always been to assert an answer without evidence, then
kill all those who doubt or disagree. At present, this is easy to
forget, since many nominally "religious" people operate
primarily under principles of secular science. (The oxymoronical
Vatican astronomer is my favorite example: It is his holy duty to
learn about the heavens, but he realizes that holy books won't
actually help, so he does what has been proven to work: He
actually looks. He uses not
religion, but science. And
in doing so he unwittingly undermines everything that the Vatican
stands for.) But there was a time when religion ruled the world:
People were burned at the stake for "heresy" and
"witchcraft," invented "crimes" so deeply
religious that the modern, secular mind can scarcely even understand
how one would ever consider them criminal.
Secondly:
Movie stars? Really, does Eldridge think so little of the scientific
community that he considers us—himself!—no wiser about the course
of humanity than a few thousand spoiled rich people who just happen
to be lucky and pretty? Does he really think that science is no
better an anchor for human decisions than petty contract negotations
or tabloid gossip? It might be right to say that scientists are no
better at making human decisions than lawyers and politicians—but
actually I don't think I agree with this either.
For
increasingly I see the world in terms of three groups: The leaders,
scientists and philosophers—the moderate-sized fraction of human
beings whose intellect and rationality supports the world against
collapse; the destroyers, terrorists
and dictators—the tiny fraction of human beings whose selfishness
and dishonesty seeks to destroy civilization from within; and the
laborers, all the
rest—the vast majority of people who simply live their lives
neutral to this ongoing conflict, doing their best to survive, but
quietly desperate for meaning. Really, it's not quite so stark as
this, since most people do live largely productive lives, as
engineers, teachers, construction workers, secretaries, soldiers,
firefighters, police officers—not the leaders who plan and shape
the future, but the workers who labor to make it possible.
Some
lawyers and politicians are in the third class of laborers—they
prosecute minor crimes or vote on infrastructure legislation. Others
are in the first class of leaders—they bring down corrupt
corporations or lead humanitarian projects. But still others are in
the second class of destroyers—they defend the corrupt corporations
for massive paychecks or start wars for personal profit. I know of
many scientists who are laborers (at present I am mostly one); I know
of a few who are leaders (Richard Dawkins, Stephen Hawking, Bill
Gates); but I know of no scientists who are destroyers, and that
makes us better than lawyers and politicians. (Indeed, the "mad
scientist" archetype is something of an oxymoron: Insofar as one
is a scientist, one is rational, and hence not mad.)
In
all, I think that NOMA is dangerously wrong; it gives power to
falsehood and faith against reason and science. People like Gould and
Elredge wouldn't have us actually ask people to believe in
science; for them, it's at best true only in a small domain; at worst
it is nothing more than an intellectual game. They would teach
children "this is how science works"—these are the
methods science involves and the facts it has found—but apparently
not "this is why science
works"—because it's actually based on determining how things
really are. On the one hand, Eldredge writes that it is an objective
fact that there were trilobites living in seas some 480 million years
ago (p.150); on the very next page he writes that we should be
careful not to challenge or disrespect the beliefs of students who
think the world was made in six days (p.151).
They
hide behind something called "methodological naturalism,"
which apparently says that we should act as if there are no
supernatural entities, even if there are—but how ridiculous that
is! If there are supernatural beings out there controlling our fate,
dammit, I want to know about it! Clearly, we should act based upon
what we think actually exists—a
position I call methodological realism. The
most probable reason why science works so well on naturalistic
assumptions is that the world really is naturalistic. This
is the same sort of hypothetical-deductive reasoning that we always
use in science—so why stop now, on the most important issues? If
there were gods and demons, there should be evidence of that; since
there isn't any evidence of them, it's most rational to infer that
they don't exist!

| Against expected utility
If I offered you the chance to play
this lottery game, just one time, would you take it?
For $1,000, you may have a 1/1,000
chance to win $10,000,000.
Your expected winnings are +$9,000! What
have you got to lose?
Oh, right: $1000. Indeed, you have a
99.9% probability of losing exactly that.
An answer often given is that the
marginal utility of wealth is not constant, that $1,000,000 isn't
really worth 1,000 times as much as $1,000. I fail to see how,
really, but even if that's true, it doesn't solve the problem.
For, on the other hand, suppose I
offered you the chance to play that game 10,000 times? If you really
had the $10,000,000 to play the game 10,000 times (or say I offered
you credit on which to do this), you'd be crazy not to! You really
would make $90,000,000 this way, with very high probability. Your
expected winnings would be your actual winnings.
If we assign a marginal utility
function so that you won't play the first game, this means that we
have U(x) such that (1/1000)*U($10,000,000) < (1)*U($1,000). But
since this is the same utility value at each play of the second game,
then you shouldn't play the second game either!
The problem is clearly expected
utility itself. For games that you only play once, you can't use
expectation values! Expectation values only make sense when you can
play many times.
Instead, I propose the principle of
most probable outcome of strategy.
If you play a long
sequence of games, this works out the same: On a large number of
plays, the most probable outcome of your strategy will be in fact the
expectation value of that strategy. (This is why you should play the
second game.)
But on fewer
plays, it is often quite different: In the first game, for instance,
the most probable outcome is clearly that you'll lose $1,000.
Moreover, this
also provides a continuous progression of intermediate states, and
there is a point at which you should just barely play: When your
probability of winning more than you lose goes above 50%.
In the games above,
your probability of losing it all on n plays in a row is
(999/1000)^n; thus, your probability of winning at least once
in n plays is 1-(999/1000)^n. Your probability of
winning more than you lose is the same as the probability that
(wins/10,000) > (losses); this is a little sticky to calculate
exactly, but as long as we play fewer than about 5,000 times, it
works out very close to the probability of winning at least
once—since one win more than covers 5,000 losses, and the
probability of winning twice in only 5,000 times is negligible.
Thus, we can say,
to a good approximation:
1-(999/1000)^n >
0.50
0.999^n > 0.50
n*ln(0.999) >
ln(0.50)
n >
ln(0.50)/ln(0.999)
n >= 693
Thus, if you can
play at least 693 times, you should play. If you can't, you
shouldn't. The expected utility is always the same—but the most
probable outcome is what you should actually be using.
Hence, I propose
that we abandon expected-utility calculations in favor of the most
probable outcome, since clearly the latter much better fits how
rational people really behave.
(This
is also why you should never play a Martingale strategy in real life:
If your win probability is above 50% on each round—e.g: you are
counting cards—you may as well bet normally. If not, a Martingale
won't help you: No matter how much money you have to lose, your most
probable outcome is still losing more than you win.)
