The Martian, the movie

(posted Sunday, 4 Oct 2015, on Facebook)

Saw The Martian today (*after* reading and posting Gary Westfahl’s review this morning — and also after reading Andy Weir’s novel a couple months ago) and I think it’s a prime example of a terrific film made from a mediocre book. The book, as I said, was formula suspense: something bad happens every 30 pages that you know our hero will overcome, because he’s the hero and has to survive. This is poor form for a novel, but a standard formula for Hollywood movies, and given the realistic depiction of the space mission and the Martian landscape, and the fine acting by all concerned, it made for riveting, frequently moving film. Kudos for the positive depiction of problem-solving and resolve, in contrast villain-formulas of so many Hollywood pics, even about space travel; for the interesting casting (following from the book) and a bit of character development (not in the book) of a couple key minor players; and for the almost uniformly plausible depictions of the space ships, their movements, the launches, the movements of people in space, and so on — nothing offhand as egregiously wrong as a couple key points in Gravity. (Acknowledging the frequently observed flaw that the thin Martian atmosphere would not whip up the storm that threatened to topple over the launch vehicle in the first place.) The 3D was impressive, though at times made everything look like toy models of landscapes, ships, even people, though I assume everything was filmed live, including the rovers crawling through the deserts of Jordan.

I still don’t find the Hermes’ captain’s obsession with ’70s music at all plausible, for reasons discussed in my review of the novel.

Finally: I appreciate the take in Gary Westfahl’s review that detects the irony between the positive view of NASA’s mission, and the unexamined assumption of the story that the whole point is to get the stranded astronaut *off* Mars. No thought about the challenges of staying, of settling — unlike any number of SF literary works. The film gives a positive spin to this, in the final scenes (not in the novel) that depict the launching of the next mission to Mars. In Gary’s review, and in Kim Stanley Robinson’s novel AURORA, and no doubt other places, there does seems to be a gradual realization within in the SF community that the visions of human colonization of planets and the expansion of humanity into the universe, will be much more difficult than those fictions have imagined… if possible, at all.

Lying with Phony Graphs

If the anti-abortion anti-Planned Parenthood folks had a case, you’d think they wouldn’t need to lie with transparently inept graphs that misrepresent the actual data. Scroll down on this link to see an actual chart, legitimately scaled, showing the services provided by Planned Parenthood, of which abortions are the least of them, by a factor of 10, in contrast to STI/STD testing, contraception, and cancer screening.

There’s a video of Planned Parenthood president Cecile Richards reacting to this graph, which she had not seen before, and despite Dan Savage’s commentary here, she doesn’t respond strongly enough — a 5 second examination of this chart, which shows, at the right side, two data points upside down: the one for abortions, at 327K, above the the one for cancer screenings, at 935K, would indicate that this picture is completely invalid as a chart of actual data.

It’s hard not to think that this is yet another example of the intellectual incompetence of the right.

Vox: Whatever you think of Planned Parenthood, this is a terrible and dishonest chart

As Friendly Atheist comments,

If you’re a pro-life politician who wants to use that information to make Planned Parenthood look evil, what do you do? Easy. You just have to assume your base isn’t intelligent enough to look into the details of whatever you show them. It worked with the recent anti-Planned Parenthood videos, after all.

Lawrence M. Krauss on Ben Carson

He says it better than I can (and of course with more authority).

Ben Carson’s Scientific Ignorance

It is hard to find a single detailed claim in his diatribe that is physically sensible or that reflects accurate knowledge about science. His central claim—that the second law of thermodynamics rules out order forming in the universe after the Big Bang—is a frequent misstatement made by creationists who want to appear scientifically literate. In reality, it is completely false.

When Carson says that scientists rely on “probability theory” to explain how multiple Big Bangs, taking place over “billions of years,” have resulted in our “perfectly ordered” universe, he’s profoundly misstating the theory of the Big Bang. (In fact, he seems to have gotten his ignorant arguments confused—his metaphor about a hurricane creating a 747 in a junkyard is often used to deride evolution, to which it is equally inapplicable.)

It is one thing to simply assert that you don’t choose to believe the science, in spite of a mountain of data supporting it. It’s another to mask your ignorance in such a disingenuous way, by using pseudo-scientific, emotion-laden arguments and trading on your professional credentials. Surely this quality, which reflects either self-delusion or, worse still, a willingness to intentionally deceive others, is of great concern when someone is vying for control of the nuclear red button.

Last week, when he was confronted, during a speech at Cedarville University, about his failure to understand basic and fundamental scientific concepts, Carson responded, “I’m not going to denigrate you because of your faith, and you shouldn’t denigrate me for mine.” What Carson doesn’t seem to recognize is that there is a fundamental difference between facts and faith. An inability to separate religious beliefs from an assessment of physical reality runs counter to the very basis of our society—the separation of church and state.

This is yet another example where one might easily conclude that conservatives, who are amenable to these kinds of arguments from incredulity (or from ignorance), are simply not very bright. Or, that Carson is appealing to a least-informed/intelligent base.

Jerry Coyne responds to the Krauss essay here.

Carson continues to insist, as do many religionists, that science, like religion, is simply a form of faith. I’ve picked the meat off that canard before, both in Slate and in Faith versus Fact, and we needn’t belabor it here. What’s funny about that argument is that it boils down to this claim by believers: “See! Science is just as bad as religion!” If they truly were equivalent, theology would have made as much progress in understanding God as science has in understanding the universe. But the score is zero for the former and a gazillion for the latter.

The Atlantic on trigger warnings; Kareem Abdul-Jabbar on the war on reason

I mentioned a while back the cover story on The Atlantic magazine’s September issue, The Coddling of the American Mind, by Greg Lukianoff and Jonathan Haidt. (Haidt is the author of the book The Righteous Mind: Why Good People Are Divided by Politics and Religion.) The essay is about the increased pervasiveness of “trigger warnings” on college campuses – advance notices to students about subjects to be discussed, e.g. incidents in novels involving sexual misconduct or racism, so that students can steel themselves as necessary, or at worst case, excuse themselves to avoid any possibility of being offended.

The editorial blurbs for this article characterize it as being a new kind of “political correctness”, but I don’t think that’s quite accurate. PC is most often cited by those who are annoyed they would get flack for offending or denigrating others, as if ordinary civility toward others, and polite nonaggression toward other points of view, amounted to a kind of socially imposed proper way to think, in Orwellian or Soviet terms. (Ironically, of course, those who resist “political correctness” are those most apt to claim exemption from criticism on the grounds of “sincerely held religious beliefs”.)

The issue at hand is something different. Yes, there are cases of women (or men) who have in fact been sexually assaulted, who find any allusion to such topics upsetting. But more often the demand for these “trigger warnings” seems to me a kind of “conservative resistance” to any ideas that might challenge the orthodoxies of these students, who are presumably in university to learn, but who wish to be shielded from anything that be contrary to their faithful worldview. At the extreme, it’s about the faithful who think it a crime for them to be offended – e.g. incidents by Muslims against Salman Rushdie or Charlie Hebdo.

But the article makes many interesting points, a few of which I’ll sample here.

The co-authors acknowledge:

There’s a saying common in education circles: Don’t teach students what to think; teach them how to think. The idea goes back at least as far as Socrates. Today, what we call the Socratic method is a way of teaching that fosters critical thinking, in part by encouraging students to question their own unexamined beliefs, as well as the received wisdom of those around them. Such questioning sometimes leads to discomfort, and even to anger, on the way to understanding.

But vindictive protectiveness teaches students to think in a very different way. It prepares them poorly for professional life, which often demands intellectual engagement with people and ideas one might find uncongenial or wrong. The harm may be more immediate, too. A campus culture devoted to policing speech and punishing speakers is likely to engender patterns of thought that are surprisingly similar to those long identified by cognitive behavioral therapists as causes of depression and anxiety. The new protectiveness may be teaching students to think pathologically.

And then they discuss changes in recent culture: how childhood has changed; how schools have become more conscious of safety; how culture has become more politically polarized.

So it’s not hard to imagine why students arriving on campus today might be more desirous of protection and more hostile toward ideological opponents than in generations past. This hostility, and the self-righteousness fueled by strong partisan emotions, can be expected to add force to any moral crusade. A principle of moral psychology is that “morality binds and blinds.” Part of what we do when we make moral judgments is express allegiance to a team. But that can interfere with our ability to think critically. Acknowledging that the other side’s viewpoint has any merit is risky—your teammates may see you as a traitor.

They discuss the “thinking cure”.

The goal is to minimize distorted thinking and see the world more accurately. You start by learning the names of the dozen or so most common cognitive distortions (such as overgeneralizing, discounting positives, and emotional reasoning; see the list at the bottom of this article). … The parallel to formal education is clear: cognitive behavioral therapy teaches good critical-thinking skills, the sort that educators have striven for so long to impart. By almost any definition, critical thinking requires grounding one’s beliefs in evidence rather than in emotion or desire, and learning how to search for and evaluate evidence that might contradict one’s initial hypothesis.

This is a very long article from which I will quote only a couple more key points and conclusions.

What are we doing to our students if we encourage them to develop extra-thin skin in the years just before they leave the cocoon of adult protection and enter the workforce? Would they not be better prepared to flourish if we taught them to question their own emotional reactions, and to give people the benefit of the doubt?

And they recommend:

Universities should also officially and strongly discourage trigger warnings. They should endorse the American Association of University Professors’ report on these warnings, which notes, “The presumption that students need to be protected rather than challenged in a classroom is at once infantilizing and anti-intellectual.” Professors should be free to use trigger warnings if they choose to do so, but by explicitly discouraging the practice, universities would help fortify the faculty against student requests for such warnings.

Not mentioned in the article, but obvious to me, is that the ultimate example of universities who shield their students from upsetting ideas are the religious colleges.

/\/\/\/\

On a related note, the October 5th issue of Time Magazine has a “viewpoint” essay about the “war on reason” by none of than Kareem Abdul-Jabbar: Ignorance Vs. Reason in the War on Education. (The title in print is “American Students — and politicians — need to stop waging war on reason”.)

The ideas are familiar enough, but are notable coming from someone you wouldn’t think especially aligned with political debate or ideological issues. But his comments are spot on, and dovetail with the Atlantic essay detailed above.

The attack on education isn’t on training our youth for whatever careers they choose, it’s on teaching them to think logically in order to form opinions based on facts rather than on familial and social influences. This part of one’s education is about finding out who you are. It’s about becoming a happier person. It’s about being a responsible citizen. If you end up with all the same opinions you had before, then at least you can be confident that they are good ones because you’ve fairly examined all the options, not because you were too lazy or scared to question them. But you—all of us—need the process. Otherwise, you’re basically a zombie who wants to eat brains because you don’t want anyone else to think either.

Thus,

That means this is a war on reason. And the generals leading the attack are mostly conservative politicians and pundits who have characterized our greatest thinkers as “elitists” who look down on everyone else. Uber-conservative William F. Buckley once said that he’d rather entrust the government to the first 2,000 people in the Boston phone book than to the faculty of Harvard University (he graduated from Yale). That’s a great sound bite that many would applaud as the triumph of street-level common sense over the egghead experts who are often viewed as impractical and removed, as if they didn’t share experiences in love and grief and raising children and paying mortgages.

And he identifies the biological and cultural culprits.

We seem hardwired to discard information that contradicts our beliefs. We have the Internet, the single most powerful information source and educational tool ever invented, but many of us use it only to confirm conclusions we didn’t arrive at through examining evidence. We go only to sites that agree with our position in order to arm ourselves with snippets that we can use as ammunition against those who disagree with us.

“The joy of college is arguing with others who are equally passionate and informed but disagree. It develops empathy for others and humility in yourself because you now will look upon your opponents not as evil idiots but as good people who want the same thing as you: a safe, loving, moral community.”

If you don’t want to read the books and develop the skills, don’t take the class. Don’t attend the college. Spend the rest of your life huddled among those who agree with you. But know that that is not thinking—it’s sleeping.

Of course this “war on reason” is fought by the ideological and religious because they know that if reason were accounted for and evidence acknowledged, their ideologies, beliefs, and faiths would be undermined.

Politics: Religion vs. Rationality

Jeffrey Tayler’s latest weekly essay at Salon, this past Sunday, can be keyed to my earlier posts about Ben Carson. Make them shut up about God: The right-wing’s religious delusions are killing us — and them.

It focuses on the second Republican debate, and how journalists defer to religious pieties.

Interviewers should be hounding faith-flaunting candidates with hard-hitting questions, as they would on any other subject of import. They should disregard faith-based assertions and demand justification on evidentiary grounds. Politicians should be made uncomfortable for ignoring the worldview and concerns of rationalists.

Sample questions to be put to pietistic contenders for the White House: What makes you believe in God? Do you hear voices? See visions? Do you believe God answers your prayers? If so, please provide objective evidence. Why is, say, the Bible or the Torah better than the Quran? Does not the eternal hellfire the supposedly merciful Jesus promised sinners epitomize Constitutionally prohibited cruel and unusual punishment? If you consider the Bible a reliable guide for your personal life, may I ask if would you slaughter your child on God’s command (as Abraham was prepared to do)? Would you stone your daughter to death for not being a virgin on her wedding night? If not, why not? What scriptural authority can you cite for following your “Holy Book” in some cases, but not in others?

I admire that Tayler is out there saying this, which many of us think. It’s a mark of progress that such things can be said in a public forum without the masses ganging up to torch the offices of Salon or the home of Jeffrey Tayler. (Actually, I doubt that many who would be offended are reading Salon. They are too busy reading their own websites, the ones that reinforce their own beliefs.)

*Of course* journalists defer to religious pieties, because they are held by the vast majority of their viewers. It would be pretty to think that political debates could be determined on rational grounds – but, to the extent rationality conflicts with those pieties, I don’t see it happening any time soon.

Evolution and the Teenaged Brain

From The New Yorker, August 31st, a review/essay by Elizabeth Kolbert on two books about the teenaged brain, The Terrible Teens. Many interesting points.

Every adult has gone through adolescence, and studies have shown that if you ask people to look back on their lives they will disproportionately recall experiences they had between the ages of ten and twenty-five. (This phenomenon is called the “reminiscence bump.”)

Why do teens engage in dangerous behavior like drinking games?

And what goes for drinking games also goes for hooking up with strangers, jumping from high places into shallow pools, and steering a car with your knees. At moments of extreme exasperation, parents may think that there’s something wrong with their teen-agers’ brains. Which, according to recent books on adolescence, there is.

Proximate cause:

According to Steinberg, adults spend their lives with wads of cotton in their metaphorical noses. Adolescents, by contrast, are designed to sniff out treats at a hundred paces. During childhood, the nucleus accumbens, which is sometimes called the “pleasure center,” grows. It reaches its maximum extent in the teen-age brain; then it starts to shrink. This enlargement of the pleasure center occurs in concert with other sensation-enhancing changes. As kids enter puberty, their brains sprout more dopamine receptors. Dopamine, a neurotransmitter, plays many roles in the human nervous system, the sexiest of which is signalling enjoyment.

“Nothing—whether it’s being with your friends, having sex, licking an ice-cream cone, zipping along in a convertible on a warm summer evening, hearing your favorite music—will ever feel as good as it did when you were a teenager,” Steinberg observes. And this, in turn, explains why adolescents do so many stupid things. It’s not that they are any worse than their elders at assessing danger. It’s just that the potential rewards seem—and, from a neurological standpoint, genuinely are—way, way greater. “The notion that adolescents take risks because they don’t know any better is ludicrous,” Steinberg writes.

Ultimate cause:

Steinberg explains the situation as the product of an evolutionary mismatch. To find mates, our primate ancestors had to venture outside their natal groups. The reward for taking chances in dangerous terrain was sex followed by reproduction, while the cost of sensibly staying at home was genetic oblivion. Adolescents in 2015 can find partners by swiping right on Tinder; nevertheless, they retain the neurophysiology of apes (and, to a certain extent, mice). Teen-agers are, in this sense, still swinging through the rain forest, even when they’re speeding along in a Tundra. They’re programmed to take crazy risks, so that’s what they do.

And then the impact of what this means for contemporary society, in which, as in so many things, our evolutionary honed behavior is at a mismatch with our current environment.

“If we were genuinely concerned about improving adolescents’ health, raising the driving age would be the single most important policy change we could make,” Steinberg writes. He favors a minimum age of eighteen.

Much the same logic applies to drinking, smoking, and doing drugs. Each year, the U.S. spends hundreds of millions of dollars on public-service campaigns designed to alert adolescents to the perils of such dissipations. Hundreds of millions—perhaps billions—more are spent reiterating this message in high-school health classes. The results have been, to put it kindly, underwhelming.

And

Many recent innovations—cars, Ecstasy, iPhones, S.U.V.s, thirty racks, semi-automatic weapons—exacerbate the mismatch between teen-agers’ brains and their environment. Adolescents today face temptations that teens of earlier eras, not to mention primates or rodents, couldn’t have dreamed of. In a sense, they live in a world in which all the water bottles are spiked. And so, as Jensen and Steinberg observe, they run into trouble time and time again.

But perhaps, it occurred to me the other day after one of my twins nearly plowed into a mailbox, to look at the problem this way is to peer through the wrong end of the MRI machine. Yes, adolescents in the twenty-first century pose a great risk to others and, statistically speaking, an even greater risk to themselves. But this is largely because other terrifying risks—scarlet fever, diphtheria, starvation, smallpox, plague—have receded. Adolescence evolved over a vast expanse of time when survival at any age was a crapshoot. If the hazards are new, so, too, is the safety. Which is why I will keep telling my kids scary stories and why they will continue to ignore them.

One of many examples about how modern human behavior seems irrational or counter-productive, but which can be understood by contrasting the environment in which human brains evolved to the modern world. (The other big one is why so many people are obese: sweets were rare in our evolutionary past, but valuable, and so humans evolved to crave them; now that sweets are plentiful, the craving has not diminished…)

Oliver Sacks on SF

There are many reasons why I might have mentioned Oliver Sacks here before, which somehow escaped me, but here’s one from a couple weeks ago. From The New Yorker, Sept 14th, a piece by Atul Gawande remembering the late Oliver Sacks. Last paragraph:

Sacks had asked me whether I’d read Forster’s “The Machine Stops.” I hadn’t, but his letter prompted me to, and I see why he was so drawn to it. It’s about a world in which individuals live isolated in cells, fearful of self-reliance and direct experience, dependent on plate screens, instant messages, and the ministrations of an all-competent Machine. Yet there is also a boy who, like Sacks, saw what was missing. The boy tells his mother, “The Machine is much, but it is not everything. I see something like you in this plate, but I do not see you. I hear something like you through this telephone, but I do not hear you. That is why I want you to come. Pay me a visit, so that we can meet face to face, and talk about the hopes that are in my mind.”

David Brooks: American Exceptionalism vs. Conservatism

David Brooks’ column in Friday’s (Sept. 25th) New York Times for once said something that completely resonates with me, without his usual waffling and obeisance to parochial religious sentiment: The American Idea and Today’s G.O.P..

He takes the idea of “American Exceptionalism” and explains how its use by some (conservatives, Republicans) is the opposite of its original meaning.

America was settled, founded and built by people who believed they were doing something exceptional. Other nations were defined by their history, but America was defined by its future, by the people who weren’t yet here and by the greatness that hadn’t yet been achieved.

Today there are some conservative commentators and Republican politicians who talk a lot about American exceptionalism. But when they use the phrase they mean the exact opposite of its original meaning. In fact, they are effectively destroying American exceptionalism.

These commentators and candidates look backward to an America that is being lost. Ann Coulter encapsulated this attitude perfectly in her latest book title, “Adios, America.” This is the philosophy of the receding roar, the mourning for an America that once was and is now being destroyed by foreign people and ideas.

Out of this backward- and inward-looking mentality comes a desire to exclude. Donald Trump talks falsely and harshly about Hispanic immigrants. Ben Carson says he couldn’t advocate putting “a Muslim in charge of this nation.”

This is an example of the bias toward thinking there were some mythical “good old days” when things were better than they are now, when men were wiser and citizens more moral, in contrast to our current debased state; another perspective on this is the similarly age-old complaint about “kids these days”.

Whereas in fact — this is where we apply evidence to try to overcome bias — the world is a safer, more inclusive, etc etc, place than it was 20 years ago, or 50, or 250. The founding fathers were not gods; their conclusions should be examined and rethought just as much as… any religious text.

As Peter Wehner, a longtime conservative writer who served in the Bush administration, wrote in the magazine Commentary: “The message being sent to voters is this: The Republican Party is led by people who are profoundly uncomfortable with the changing (and inevitable) demographic nature of our nation. The G.O.P. is longing to return to the past and is fearful of the future. It is a party that is characterized by resentments and grievances, by distress and dismay, by the belief that America is irredeemably corrupt and past the point of no return. ‘The American dream is dead,’ in the emphatic words of Mr. Trump.”

With some references to the reality behind conservative fear and paranoia:

This pessimism isn’t justified by the facts. As a definitive report from the National Academies of Sciences, Engineering and Medicine recently found, today’s immigrants are assimilating as fast as previous ones. They are learning English. They are healthier than native-born Americans. Immigrant men age 18 to 39 are incarcerated at roughly one-fourth the rate of American men.

We’ve mentioned this immigrant issue before.

My take on American Exceptionalism is that it’s an example of the self-enhancement bias. Obama mentioned once that other countries [think, France!] are pleased to imagine themselves similarly exceptional, and was excoriated by the right.

Salman Rushdie, Two Quotes

Yesterday’s (print) New York Times Book Review, the Inside the List commentary, discussing Salman Rushdie’s new novel. (Paul Di Filippo’s review, posted last Friday, was seen by Rushdie himself, who tweeted it to his 1M+ followers — you can see it on his twitter feed. Paul is chuffed.) The commentary quotes an interview with Rushdie:

The book is, in part, an epic fantasy about a war between faith and reason, themes close to Rushdie’s heart. “There’s all this science fiction about people inventing computers that then become hostile to the people who created them,” he told The National Post in Canada recently. “I think of God as an idea that was developed at a time where human beings understood much less about the world we’re in. And then God became a useful way of putting together a moral code, the commandments and so on, and now, speaking for myself, I don’t need God to explain the question of origin. And I don’t want God to determine what my commandments should be. I find God to be an irrelevant idea. But on the other hand, there he is in the middle of the room, completely out of control.”

When listing that new book a couple weeks ago, I scanned his Wikipedia page, and noticed this paragraph that speaks to the issue of the value of narrative:

We need all of us, whatever our background, to constantly examine the stories inside which and with which we live. We all live in stories, so called grand narratives. Nation is a story. Family is a story. Religion is a story. Community is a story. We all live within and with these narratives. And it seems to me that a definition of any living vibrant society is that you constantly question those stories. That you constantly argue about the stories. In fact the arguing never stops. The argument itself is freedom. It’s not that you come to a conclusion about it. And through that argument you change your mind sometimes. … And that’s how societies grow. When you can’t retell for yourself the stories of your life then you live in a prison. … Somebody else controls the story. … Now it seems to me that we have to say that a problem in contemporary Islam is the inability to re-examine the ground narrative of the religion. … The fact that in Islam it is very difficult to do this, makes it difficult to think new thoughts.

Ben Carson follow-up

I wrapped up my previous post about Ben Carson a bit too hastily, because I do have a fairly solid provisional conclusion about why some people don’t “believe” in science and ascribe instead to faith or various subjectively attractive supernatural explanations. It’s because humans are social animals first and foremost (rather than, say, rational animals), and the social bonds formed between families, neighborhoods, congregations, and others who may be presumed to have similar values, is of central importance to the vast majority of humans. Abstract ideas about the outer world, or what happened in the past or might happen in the future (more than a generation or so, in the life of one’s kids), is of intellectual interest at best, and very rarely to be taken into account if it threatens in any way the shared assumptions of one’s social groups [which ultimately, as explained, is about genetic survival]. To challenge the beliefs of one’s social groups is to risk ostracism, as does in fact happen to religious apostates and to kids who grow up non-heterosexual (thus threatening the continued familial line) or who challenge their community’s faith (thus representing to others in the community someone who can’t be ‘trusted’ to behave according to their standards).

Ben Carson and his ilk aren’t necessarily dumb (though many people who dismiss scientific ideas on the basis of superficial implausibility are; they are simply unable to draw deductive conclusions, or are unwilling or too impatient to follow an argument for why something obvious to common sense may not be true). Ben Carson and Mike Huckabee and their ilk are advertising to their followers – this is what politicians, especially, do – that *I am one of you*! I share your values! I share your prejudices! I share your ignorance! Because there are enough people out there to follow such a leader to make it worth sacrificing whatever intellectual integrity they might otherwise have.
