The Science of Why We Don't Believe Science - 0 views

  • In the annals of denial, it doesn't get much more extreme than the Seekers. They lost their jobs, the press mocked them, and there were efforts to keep them away from impressionable young minds. But while Martin's space cult might lie at on the far end of the spectrum of human self-delusion, there's plenty to go around. And since Festinger's day, an array of new discoveries in psychology and neuroscience has further demonstrated how our preexisting beliefs, far more than any new facts, can skew our thoughts and even color what we consider our most dispassionate and logical conclusions. This tendency toward so-called "motivated reasoning [3]" helps explain why we find groups so polarized over matters where the evidence is so unequivocal: climate change, vaccines, "death panels," the birthplace and religion of the president [4] (PDF), and much else. It would seem that expecting people to be convinced by the facts flies in the face of, you know, the facts.
  • The theory of motivated reasoning builds on a key insight of modern neuroscience [5] (PDF): Reasoning is actually suffused with emotion (or what researchers often call "affect"). Not only are the two inseparable, but our positive or negative feelings about people, things, and ideas arise much more rapidly than our conscious thoughts, in a matter of milliseconds—fast enough to detect with an EEG device, but long before we're aware of it. That shouldn't be surprising: Evolution required us to react very quickly to stimuli in our environment. It's a "basic human survival skill," explains political scientist Arthur Lupia [6] of the University of Michigan. We push threatening information away; we pull friendly information close. We apply fight-or-flight reflexes not only to predators, but to data itself.
  • a subconscious negative response to the new information—and that response, in turn, guides the type of memories and associations formed in the conscious mind. "They retrieve thoughts that are consistent with their previous beliefs," says Taber, "and that will lead them to build an argument and challenge what they're hearing."

  • But reasoning comes later, works slower—and even then, it doesn't take place in an emotional vacuum.
  • In other words, when we think we're reasoning, we may instead be rationalizing.
  • That's not to suggest that we aren't also motivated to perceive the world accurately—we are. Or that we never change our minds—we do. It's just that we have other important goals besides accuracy—including identity affirmation and protecting one's sense of self—and often those make us highly resistant to changing our beliefs when the facts say we should.
  • Ironically, in part because researchers employ so much nuance and strive to disclose all remaining sources of uncertainty, scientific evidence is highly susceptible to selective reading and misinterpretation.
  • people's deep-seated views about morality, and about the way society should be ordered, strongly predict whom they consider to be a legitimate scientific expert in the first place—and thus where they consider "scientific consensus" to lie on contested issues.
  • In Kahan's research [13] (PDF), individuals are classified, based on their cultural values, as either "individualists" or "communitarians," and as either "hierarchical" or "egalitarian" in outlook.
  • The results were stark: When the scientist's position stated that global warming is real and human-caused, for instance, only 23 percent of hierarchical individualists agreed the person was a "trustworthy and knowledgeable expert." Yet 88 percent of egalitarian communitarians accepted the same scientist's expertise.
  • people rejected the validity of a scientific source because its conclusion contradicted their deeply held views—and thus the relative risks inherent in each scenario.
  • head-on attempts to persuade can sometimes trigger a backfire effect, where people not only fail to change their minds when confronted with the facts—they may hold their wrong views more tenaciously than ever.
  • A key question—and one that's difficult to answer—is how "irrational" all this is. On the one hand, it doesn't make sense to discard an entire belief system, built up over a lifetime, because of some new snippet of information. "It is quite possible to say, 'I reached this pro-capital-punishment decision based on real information that I arrived at over my life,'" explains Stanford social psychologist Jon Krosnick [21]. Indeed, there's a sense in which science denial could be considered keenly "rational." In certain conservative communities, explains Yale's Kahan, "People who say, 'I think there's something to climate change,' that's going to mark them out as a certain kind of person, and their life is going to go less well."
  • people gravitate toward information that confirms what they believe, and they select sources that deliver it. Same as it ever was, right? Maybe, but the problem is arguably growing more acute, given the way we now consume information
  • a higher education correlated with an increased likelihood of denying the science on the issue.
  • one insidious aspect of motivated reasoning is that political sophisticates are prone to be more biased than those who know less about the issues.
  • It all raises the question: Do left and right differ in any meaningful way when it comes to biases in processing information, or are we all equally susceptible?
  • Some researchers have suggested that there are psychological differences between the left and the right that might impact responses to new information—that conservatives are more rigid and authoritarian, and liberals more tolerant of ambiguity. Psychologist John Jost of New York University has further argued that conservatives are "system justifiers": They engage in motivated reasoning to defend the status quo.
  • What can be done to counteract human nature itself?
  • Given the power of our prior beliefs to skew how we respond to new information, one thing is becoming clear: If you want someone to accept new evidence, make sure to present it to them in a context that doesn't trigger a defensive, emotional reaction.
  • Kahan infers that the effect occurred because the science had been written into an alternative narrative that appealed to their pro-industry worldview.
  • You can follow the logic to its conclusion: Conservatives are more likely to embrace climate science if it comes to them via a business or religious leader, who can set the issue in the context of different values than those from which environmentalists or scientists often argue. Doing so is, effectively, to signal a détente in what Kahan has called a "culture war of fact." In other words, paradoxically, you don't lead with the facts in order to convince. You lead with the values—so as to give the facts a fighting chance.

Can Objectivism Be Criticised? - 0 views

  • Most of Rand’s critics have probably read her key essays several times over, so if they don’t understand them maybe it’s because Rand isn’t as clear as her acolytes claim.

  • Rand herself became irate when informed by Joan Blumenthal that the tree she thought she saw outside her hospital window was really an IV pole.
  • Ethics
  • Politics
  • Religion
  • Although Objectivists tell us how stunningly original Rand was, most of her ideas and even the way she defends them are quite similar to other thinkers and schools of philosophy.
  • “Objectivism is a version of empiricism.” As such it is subject to the standard criticisms of empiricism, in particular the difficulty of explaining necessity, mathematics and logic without the aid of a priori knowledge. Another example is Rand’s belief that man’s mind is tabula rasa, which makes it subject to various objections from evolutionary psychology.
  • If an Objectivist historian of science and an Objectivist physicist can’t get issues right in their own field whereas Leonard Peikoff (who has expertise in neither) can, what’s the hope for the rest of us?

What will happen to us? - 0 views

  • Most humans who have ever lived have died in conditions almost exactly like the ones into which they were born, and without written history had no way to grasp that the future might be different at all. Only now have we gained the scientific knowledge necessary to appreciate how exactly how deep a rabbit-hole the future really is: not just long enough to see empires rise and crumble, but long enough to make all human history so far seem like a sneeze of the gods.

"It won't be humans who witness the sun's demise: It will be entities as different from us as we are from a bug.""

Rand & Aesthetics 19 - 0 views

  • A certain type of confusion about the relationship between scientific discoveries and art, leads to a frequently asked question: Is photography an art? The answer is: No.
  • Beyond demonstrating her lack of specific knowledge about photography, this passage also shows the weakness of her theory of definitions. Much of Rand's argument against photography as art stems from her entirely arbitrary definition of art as "selective recreation."
  • There is no such thing as a right or wrong definitions: there are merely definitions excepted by most people and definitions accepted only by individuals or eccentric groups (e.g., Objectivist definitions).
  • ...3 more annotations...
  • She tries to defend this point of view by emphasizing the importance of selecting only those concretes that are "abstract essentials."
  • On purely philosophical grounds, therefore, Rand's assertion that photography is not art is insupportable. Yet, curiously enough, it's not even consistent with Rand's own definition. Rand's belief that art photography involves only an insignificant bit of selectivity demonstrates her ignorance of that particular art. It also demonstrates the dangers of making dogmatic assertions about subjects you don't know much about.
  • Photography, she claims, is mostly a technique; but the same could be said of painting and sculpture. The main difference between painting and photography is the tools: one creates images with paint, brushes, and canvas, the other with a camera, lenses, and filters. Otherwise, they are merely two means of achieving the same end: creating two-dimensional images.

    "Photography. Ayn Rand, to the bewilderment of photographers everywhere, denies that photography is an art" Par for the course, really.

Rand & Aesthetics 17 - 0 views

  • In her haste to find a pretext for calling "modern" music non-art, Rand, in her carelessness, has once again presented a hollow argument. It may be annoying and even aesthetically viscious for avant-garde composers to introduce taped sounds of machine and street noises into their musical compositions. But that, in itself, doesn't render the musical portions of such compositions any less musical. Before one denounces a given aesthetic style, one at least has to take the trouble to understand that style. Otherwise, one comes off as prejudiced rather than insightful, as an aesthetic ignoramus rather than a knowledgable critic.
  •  
    "Ayn Rand's most extended published take on "modern music" appears in her "Art and Cognition" essay. It features all the usual Randian intellectual vices: tendency toward over-generalization, vagueness, lack of specific examples, and condemnation via implicit suggestion and innuendo:"

Rationally Speaking: Is Stanley Fish smarter than Richard Dawkins? - 0 views

  • Was Darwin a fool who had not understood the Foucaultian implications of his own realization of the complex relationship between facts and theories? No, the problem lies with Fish’s cheap rhetorical trick: Stanley seems to think that once one has refuted the naive logical positivist view that human beings can adopt a purely objective viewpoint and grasp reality for what it actually is (a position that in philosophy has been abandoned since the 1950s, by the way), voilà, all knowledge has ultimately been shown to be a matter of faith.
  • This is an almost comical example of a well known logical fallacy known as the false dichotomy, very popular in politics (remember “you are either with us or against us”?), but which Fish should really know how to avoid.
  • But the framework and the assumptions don’t need to be arbitrary. In science, they are not (contrary to postmodern literary criticism). Science and reason are not like edifices built on a foundation, whereby one only has to show that the foundation is shaky for the whole edifice to come down.

    "I could write a book refuting the nonsense regularly expounded by New York Time's columnist Stanley Fish. Oh, wait, I almost have written a book about it! I already commented on this blog regarding Stanley's thoughts concerning academic freedom, deconstructionism, and the New Atheism (part 1 and part 2). I was going to leave Fish alone for a while, but today three friends independently sent me his latest column and asked me to write about it, so here we go, again..."
