Conservatives and Evangelical Christians constitute the core of public support for President Trump. Many of them have felt besieged and under direct attack for decades. In retrospect, it may have been the case that America's changing social and legal landscape was simply too much for these groups to tolerate. The backlash gave us Trump and the rise of anti-democratic authoritarianism.
The Washington Post writes:
Throughout the 1960s and 1970s, evangelicals became anxious about perceived threats to white Christian culture in America. In 1962 and 1963, the Supreme Court removed prayer and mandatory Bible reading from public schools. The Hart-Cellar Act of 1965 increased diversity in the country by opening it to large numbers of non-western immigrants, who brought their diverse religious beliefs with them.
In 1971, the Supreme Court, in Green v. Connolly, stripped the tax-exempt status from institutions that discriminated in their admissions policies based on race. This affected a host of Southern Christian schools and academies, many of which saw the decision in terms of “big government” threatening their religious liberty — the liberty to discriminate based upon their reading of the Bible.
And, of course, in 1973 the Court supported a women’s right to an abortion in Roe v. Wade.
Jerry Falwell, a Baptist minister from Lynchburg, Va., formed the Moral Majority to “train, mobilize, and electrify the Religious Right” in preparation to fight a “holy war” for the moral soul of America. Falwell’s organization played a major role in electing Ronald Reagan as president in 1980 and shaped a vision for white conservative evangelical political activity that remains strong today.
Today, the Christian right remains focused on the Supreme Court, which many evangelicals see as the chief impediment to their agenda on issues ranging from school prayer to LGBTQ rights to abortion. Their political playbook requires evangelicals to elect an attentive president who, in turn, will appoint socially conservative federal judges. Once these judges are in place, evangelicals believe they will be better positioned to win the battles over these key issues; saving the nation would avoid divine punishment for its sins.
That idea has remained so potent over the decades because it is embedded in evangelical churches. Pastors use their pulpits to speak about these cultural issues. Adult education classes in churches often focus on such topics. Members of small-group Bible studies discuss them. Some church leaders consistently stoke fear in their congregations by pointing to threats to religious liberty, both real and imagined."
Asymmetric war: With a mindset driven by fear and grounded in infallible religious moral rectitude, one can see a little about why there is little or no interest in compromise. To the Evangelical mindset, compromise makes no sense. But that righteous fervor blinds Evangelicals to another truth: Each of their counterattacks, say by overturning Roe v. Wade, often or always constitutes a much more aggressive attack on people who disagree. In the case of abortion, Roe forces no woman to get an abortion against her will. On the other hand, Evangelicals are eager to force their religious belief on women by blocking access to abortion for women who want one. That is highly intrusive."
The threats here are not symmetrical. Evangelicals simply cannot see the asymmetry, maybe because they know they cannot be wrong. At present, the state is far more threatened by the church than the other way around.

The 2018 Presidential Greatness Survey
Tuesday, April 2, 2019
The 2018 Presidential Greatness Survey is posted below. The highlights are that people who are expert in presidents and presidential politics ranked President Trump (1) last in terms of greatness, and (2) highest in terms of being polarizing. Professor Rottinghaus graciously sent the 13-page study report to me, which is posted below.

The Science of Morality & Human Well-Being
March 25, 2019
Nihilism: 1. the rejection of all religious and moral principles, in the belief that life is meaningless; 2. belief that all values are baseless and that nothing can be known or communicated
In the last few months, some commentary here and elsewhere have raised the idea that many concepts related to politics, concepts relating to concepts such as good and evil, fact and non-fact, logic and illogic, and truth and lie are essentially meaningless. Meaninglessness arises from subjectivity that can be inherent in things one might think of as mostly objective. For example, some people believe it is a fact that there is a strong consensus among expert climate scientists that anthropogenic global warming is real. About 27% of Americans reject that as false and no amount of discussion and citing fact sources will change most (~ 98% ?) of those minds.
Does that mean there is no way to discern facts or truth from lies or misinformation? When it comes to morality, is nihilism basically correct and contemplating morality from any point of view is too subjective to be meaningful in any way?
In another example, the rule of law concept is seen by some analysts as an essentially contested concept, which is something subjective and not definable such that a large majority of people will agree on what the rule of law is and when it applies. If the rule of law cannot be defined, how can what is moral and what isn't be defined?
Pragmatic rationalism: The anti-bias ideology advocated here, “pragmatic rationalism”, is built on four core moral values, (1) respect for objective facts and truth, to the extent they can be ascertained, (2) application of less biased logic (conscious reasoning) to the facts and truths, (3) service to the public interest, which is conceived as a transparent competition of ideas constrained by facts and logic, and (4) reasonable compromise in view of political, social and other relevant factors. If nihilism is correct, the anti-bias ideology is nonsense.
Science and morality: In his 2010 book, The Moral Landscape: How Science Can Determine Human Values, neuroscientist Sam Harris argues there can be enough objectivity in matters of morals and human behavior and well-being that there is a great deal of objectivity in morality. In essence, Harris is arguing that science can find things that foster human well-being by tending to make people, e.g., happy, unhappy, and socially integrated or not. On morals, religion, secularism and the role of science in discovering morality, Harris writes:

In essence, Harris is arguing that science can find things that foster human well-being by tending to make people, e.g., happy, unhappy, and socially integrated or not. On morals, religion, secularism and the role of science in discovering morality, Harris writes:
On the first account, to speak of moral truth is, of necessity, to invoke God; on the second, it is merely to give voice to one’s apish urges, cultural biases and philosophical confusion. My purpose is to persuade you that both sides in this debate are wrong. The goal of this book is to begin a conversation about how moral truth can be understood in the context of science.
While the argument I make in this book is bound to be controversial, it rests on a very simple premise: human well-being entirely depends on events in the world and on states of the human brain. A more detailed understanding of these truths will force us to draw clear distinctions between different ways of living in society with one another, judging some to be better or worse, more or less true to the facts, and more or less ethical. I am not suggesting that we are guaranteed to resolve every moral controversy through science. Differences of opinion will remain—but opinions will be increasingly constrained by facts.
Does our inability to gather the relevant data oblige us to respect all opinions equally? Of course not. In the same way, the fact that we may not be able to resolve specific moral dilemmas does not suggest that all competing responses to them are equally valid. In my experience, mistaking no answers in practice for no answers in principle is a great source of moral confusion.
The the deeper point is that there simply must be answers to questions of this kind, whether we know them or not. And these are not areas where we can afford to respect the “traditions” of others and agree to disagree. . . . . I hope to show that when we are talking about values, we are actually talking about an interdependent world of facts.
There are facts to be understood about how thoughts and intentions arise in the human brain; there are further facts to be known about how these behaviors influence the world and the experience of other conscious beings. We will see that facts of this sort will exhaust what we can reasonably mean by terms like “good” and “evil”. They will increasingly fall within the purview of science and run far deeper than a person’s religious affiliation. Just as there is no such thing as Christian physics or Muslim algebra, we will see that there is no such thing as Christian or Muslim morality. Indeed, I will argue that morality should be considered an undeveloped branch of science.
Having received tens of thousands of emails and letters from people at every point on the continuum between faith and doubt, I can say with some confidence that a shared belief in the limitations of reason lies at the bottom of these cultural divides. Both sides [Christian conservatives and secular liberals] believe that reason is powerless to answer the most important questions in human life.
The scientific community’s reluctance to take a stand on moral issues has come at a price. It has made science appear divorced, in principle, from the most important questions of human life.
It seems inevitable, however, that science will gradually encompass life’s deepest questions. How we respond to the resulting collision of worldviews will influence the the progress of science, of course, but may also determine whether we succeed in building global civilization based on shared values. . . . . Only a rational understanding of human well-being will allow billions of us to coexist peacefully, converging on the same social, political, economic and environmental goals. A science of human flourishing may seem a long way off, but to achieve it, we must first acknowledge that the intellectual terrain actually exists.Harris is right, nihilism is wrong: If Harris is correct that intellectual moral terrain actually exists and is subject to scientific scrutiny, then pragmatic rationalism would seem to be a political counterpart of Harris’ vision of what can lead to human well-being for the long run. Maybe because of personal bias and/or the amazingly good fit between what Harris argues and the core moral values that pragmatic rationalism is built on, Harris is right. Science can shed light on an at least somewhat objective vision of right and wrong, good and evil. Nihilism is wrong and destructive of both self and civilization.

What the unconscious mind thinks of interracial marriage
Saturday, March 23, 2019
The human mind operates simultaneously on two fundamentally different tracts, unconscious thinking and conscious thinking. Recent estimates accord unconscious thinking with about 95-99.9% of human mental bandwidth, decision-making influence or "firepower." The rest is our conscious thinking. Conscious and unconscious thinking or decisions can be in conflict. The split human reaction to interracial marriage is a case in point.
A recent Washington Post article describes brain responses to photos of same-race and different race married heterosexual couples. The article is based on data published in a recent paper in the Journal of Experimental Social Psychology "Yuck, you disgust me! Affective bias against interracial couples"
Brain scans of people who claim to have no disapproval of or bias against interracial couples show disgust or disapproval of photos that show interracial couples (black and white), but not photos of black couples or white couples.
According to the WP article, "Researchers found that the insula, a part of the brain that registers disgust, was highly active when participants viewed the photos of the interracial couples, but was not highly engaged when viewers saw the images of same-race couples, whether they were white or black."
This shows the possibility of disconnects between what the unconscious mind sees, thinks and decides, i.e., disgust toward interracial couples, and what the conscious mind sees, thinks and decides, i.e., acceptance of interracial couples.
What may be unusual about this difference of opinion is that, at least for young people (college student volunteers in this case), the conscious mind dictates personal belief and behavior toward interracial couples despite a contrary innate unconscious belief or judgment. For politics and social matters like this, that triumph of the weak human conscious mind over our powerful unconscious mind is the rare exception, not the rule.
For better or worse, that's just the nature of what evolution conferred on the human species in terms of how we see and think about what we think we see in the world.
Questions: Does the data show disgust, or is data obtained from the human brain simply not believable? Is it possible that our unconscious mind can be so powerful compared to our conscious thoughts and reason?

The human species' greatest threat
Saturday, March 23, 2019
The human species faces a number of threats that could damage civilization or, in the worst case, lead to extinction. A major nuclear war would at least significantly damage civilization. At least hundreds of millions of people would die. Polluting human activity could initiate a chain reaction that leads to a toxic environment and possibly human extinction. Various climate change episodes that caused mass land animal extinctions are known, e.g., anoxic events and the Permian-Triassic extinction event or Great Dying of about 252 million years ago. Given incomplete human knowledge, it is possible that human activity could trigger such an event without human awareness until it is too late to save the species.
If humans do wind up damaging or destroying modern civilization or even annihilating the human species, the ultimate cause would necessarily come from some sort of human behavior that is at least theoretically avoidable. The question is, what is mankind's greatest survival threat?
This discussion excludes threats that humans simply cannot affect or prevent, e.g., a mass extinction caused by eruption of a supervolcano.
The human cognition threat: From a cognitive and social science point of view, the greatest threat lies in the nature of human cognition and the irrational politics it engenders. That directly reflects human biology. In turn, that directly reflects the intellectual firepower that evolution endowed the human species with. Whatever mental capacity humans have as individuals and when acting in groups or societies, it was undeniably sufficient to get humans to where we are today.
The unanswered question is whether what evolution resulted in is sufficient to survive our technology and ability to kill ourselves off.
Under the circumstances, humanity's greatest threat lies in the psychology of being human. The very nature of human sentience and the individual and group behavior that flow therefrom are the seeds of human self-annihilation. If, when and why the seeds might sprout are open questions. Nonetheless, the seeds are real and viable.
Within the last century, research from cognitive, social and other relevant branches of science proved that all humans are driven mostly by our unconscious minds, which are intuitive-emotional-moral. In terms of politics and religion, output from our unconscious minds are not mostly fact- and logic-based. Powerful unconscious biases heavily affect what little we wind up becoming consciously aware of. As a consequence, we are not primarily driven by objective fact or logic. Instead, (i) false perceptions of reality or facts, and (ii) conscious thinking (reason or common sense) that is heavily influenced by powerful unconscious biases drives thought, belief and behavior.
Although we are sentient and conscious, unconscious (intuitive-emotional-moral) mental bandwidth or thinking is 100 million to 100 billion times more powerful than conscious thought. For better or worse, the human mental constitution dominated by unconscious intuitive knowledge and thought was sufficient for modern humans to survive and dominate.
None of that is a criticism of humans or their intellectual makeup. Those are objective facts based on modern science.
That biology applies to politics and it always has. In other words, politics is mostly irrational and based on false information, conscious thinking (common sense) that is heavily biased by unconscious personal beliefs and morals and evolutionary biases that all humans share.
Misinformation is easy to acquire and very hard to reject, especially when it rejecting it undermines personal ideology, belief or morals. Often or usually, there is insufficient information or situations are too complex or opaque for true objectivity. The unconscious human mind nonetheless has to act in the face of that. In their 2016 book Democracy For Realists: Why Elections Do Not Produce responsive Governments, social scientists Christopher Achen and Larry Bartels summarized the human condition in politics like this:
“. . . . the typical citizen drops down to a lower level of mental performance as soon as he enters the political field. He argues and analyzes in a way which he would readily recognize as infantile within the sphere of his real interests. . . . cherished ideas and judgments we bring to politics are stereotypes and simplifications with little room for adjustment as the facts change. . . . . the real environment is altogether too big, too complex, and too fleeting for direct acquaintance. We are not equipped to deal with so much subtlety, so much variety, so many permutations and combinations. Although we have to act in that environment, we have to reconstruct it on a simpler model before we can manage it.”
All modern societies operate under some form of government and political system. What nations, societies, groups and individuals do and don't do is governed by human biology. That is mostly governed by our heavily biased, unconscious perceptions of reality (facts) and thinking. That irrationality, disconnection from reality and associated group behavior, including a lack of empathy toward outsiders, is where the greatest threat to the human species resides.
Questions: Is humanity's greatest threat the imperfect cognitive and social biology that underpins politics? If it is, can our weak, usually deceived and misinformed conscious minds do anything to change the status quo? Or, as some cognitive and social scientists at least imply, are humans destined to never rise much above their innate cognitive and social biology, leaving the fate of the human species up to irrational biology?

Book Review: The User Illusion
Saturday, March 23, 2019
In The User Illusion: Cutting Consciousness Down To Size (Penguin Books, 1991, English translation 1998), Danish science writer Tor Norretranders dissects the powerful illusion that humans believe that what they see and think is real. The User Illusion (TUI) relentlessly describes human consciousness and the false reality that we believe is real. TUI is about the constraints on knowledge. The 2nd law of thermodynamics and the curse of always increasing disorder (entropy), information theory and mathematics all make it undisputable that everything sentient in the universe operates under severe constraints. That includes all forms of life and the limits on the human mind. To believe otherwise is a mistake, or more accurately, an illusion.
TUI’s chapter 6, The Bandwidth of Consciousness, gets right to the heart of matters. Going there is an enlightening but humbling experience. When awake, the information flow from human sensory nerves to the brain is about 11.2 million bits per second, with the eyes bringing in about 10 million bits per second, the skin about 1 million bits per second, with the ears and nose each bringing in about 100,000 thousand bits per second. That’s a lot, right? No, it isn’t. The real world operates at unknowable trillions of gigabits/second, so what we see or perceive isn’t much. It’s puny, actually.
But, remember, we needed only enough capacity to survive, not to know the future 10 or 100 years in advance or to see a color we can’t see using eyes with just three different color sensing cell types. For human survival, three colors was good enough. Evidence of evolutionary success is a planet population of 7 billion humans that’s rapidly heading toward 8 billion.
Although that 11.2 million bits/second may sound feeble, things are much, much weirder than just that. The 11.2 million bits/second are flowing into our unconscious minds. We are not conscious of all of that. So, what is the bandwidth of consciousness? How much of the 11.2 million bits/second we sense do we become aware of? The answer is an even more humbling 1-50 bits/second. At least, that’s the estimated rate at which human consciousness processes the information it is aware of. Silently reading this discussion consumes about 45 bits/second, reading aloud consumes about 30 bits/second, multiplying and adding two numbers consumes about 12 bits/second, counting objects consumes about 3 bits/second and distinguishing between different degrees of taste sweetness consumes about 1 bit/second.
What’s going on here??: It’s fair to ask what's really going on and why does our brain operate this way. The answer to the last question is that (i) it’s all that was needed to survive, and (ii) the laws of nature and the nature of biological organisms like humans are simply limited in what they can do. The human brain is large relative to body size but nonetheless only it processes information at a maximum rate of about 11.2 million bits/second because that’s what evolution conferred.
The more interesting question is what’s going on? What’s going on is that our unconscious mind takes in information at about 11.2 million bits/second, discards what’s not important or needed, which is about 11.2 million bits/second minus about 50 bits/second and then presents the little trickle of important information to consciousness. That’s how much bandwidth humans need, e.g., for finagling sex, spotting and running away from a hungry saber tooth cat before being eaten, finding or hunting food, or whatever was needed to survive.
Where things get very, very strange is in the presentation of the little trickle to consciousness. Discussing that step is a different discussion, but a glimpse of it as applied to politics is in the Democracy for Realists book review. This discussion focuses on the human brain operating system and the inputs and outputs it deals with and creates.
If one accepts the veracity of the science and Norretrander’s narrative, it is fair to say that the world that humans think they see is more illusion than real. Other chapters of TUI and the science behind the observations reinforce this reality of human cognition and its limits. For example, chapter 9, The Half-Second Delay, describes how our unconscious minds make decisions about 0.5 second before we become aware of what it is we have unconsciously decided. Despite that, we consciously believe that we made a decision about 0.5 second before we became aware of it. We trick ourselves.
In other words, we operate under an illusion that our conscious minds is making decisions when in fact that is the rare exception. The rule is that our unconscious minds are calling the shots most of the time. When it comes to perceiving reality, the low-bandwidth signal the brain uses to create a picture is a simulation that we routinely mistake for reality. As Norretranders sees it, consciousness is a fraud. That’s the user illusion.

Where things get very, very strange is in the presentation of the little trickle to consciousness. Discussing that step is a different discussion, but a glimpse of it as applied to politics is in the Democracy for Realists book review. This discussion focuses on the human brain operating system and the inputs and outputs it deals with and creates.
If one accepts the veracity of the science and Norretrander’s narrative, it is fair to say that the world that humans think they see is more illusion than real. Other chapters of TUI and the science behind the observations reinforce this reality of human cognition and its limits. For example, chapter 9, The Half-Second Delay, describes how our unconscious minds make decisions about 0.5 second before we become aware of what it is we have unconsciously decided. Despite that, we consciously believe that we made a decision about 0.5 second before we became aware of it. We trick ourselves.
In other words, we operate under an illusion that our conscious minds is making decisions when in fact that is the rare exception. The rule is that our unconscious minds are calling the shots most of the time. When it comes to perceiving reality, the low-bandwidth signal the brain uses to create a picture is a simulation that we routinely mistake for reality. As Norretranders sees it, consciousness is a fraud. That’s the user illusion.
