DP Etiquette

First rule: Don't be a jackass.

Other rules: Do not attack or insult people you disagree with. Engage with facts, logic and beliefs. Out of respect for others, please provide some sources for the facts and truths you rely on if you are asked for that. If emotion is getting out of hand, get it back in hand. To limit dehumanizing people, don't call people or whole groups of people disrespectful names, e.g., stupid, dumb or liar. Insulting people is counterproductive to rational discussion. Insult makes people angry and defensive. All points of view are welcome, right, center, left and elsewhere. Just disagree, but don't be belligerent or reject inconvenient facts, truths or defensible reasoning.

An Irrational Mind Meets Coronavirus

A favela in Brazil


The New York Times reports that Jair Bolsonaro, Brazil's president, has called the virus a “measly cold.” He is the last major world leader who questions lockdown measures. The NYT writes
“RIO DE JANEIRO — As coronavirus cases and deaths mount in Brazil, President Jair Bolsonaro has remained defiant, the last notable holdout among major world leaders in denying the severity of the coronavirus. 
Brazilians, he declared last week, are uniquely suited to weather the pandemic because they can be dunked in raw sewage and “don’t catch a thing.” 
Defying guidelines issued by his own health ministry, the president on Sunday visited a busy commercial district in Brasília, the capital, where he called on all but elderly Brazilians to get back to work. 
Then he insisted that an anti-malaria pill of unproved efficacy would cure those who fall ill with the virus that has killed more than 43,000 people worldwide.”

It will be interesting and sad to see how the virus will ravage a country that doesn't even try to deal with it. The US is projecting up to 240,000 deaths if containment measures are strictly adhered to. With no containment measures Brazil is probably going to experience the collapse of its health care system and several million deaths. The next 3-4 weeks will be instructive.





Coronavirus Compared to the Flu Virus

Vox produced an excellent 7-minute video on the difference between the flu and the current coronavirus. This really puts the two viruses in an easy to understand context. Vox writes:

“Covid-19, the disease caused by the coronavirus, can look very similar to the flu. They have similar symptoms — a fever, cough, and the possibility of leading to pneumonia — and even spread the same way. So wanting to compare the two is natural and, frankly, understandable. 
But Covid-19 is very different from the flu. It’s more dangerous in almost every way. 
Not only is it twice as contagious, but the time it takes you to realize you are contagious is much longer. With the flu, the average time it takes you to feel sick from the moment you become sick (called the incubation period) is two days.”

Book Review: Democracy for Realists

Peepsheep


The book, Democracy For Realists: Why Elections Do not Produce Responsive Governments (Christopher H. Achen and Larry M. Bartels (“A&B”), 2016) analyzes data on the nature of voting and democracy in America and other countries from the early 1900’s through 2012. Much of they find isn’t anywhere close to what people believe about the elements of democracy under the folk theory, e.g., where sovereignty resides, “the will of the people”, or the true nature of voters’ role in democracy.

A&B, both social scientists, have found that most American's vision of what democracy is has little to do with the reality of democracy. Instead of ideology and logic defining voter's political beliefs, party affiliation and voting preferences, the evidence points instead to people's social identities. Due to their misunderstanding, frustrated voters try to “fix” certain aspects of democracy by, e.g., imposing term limits or resorting to state level ballot measures. Analysis of the data suggests that those measures mostly backfire and tend to shift power from voters to special interests. The key lesson this book has to teach is that fixing democracy requires understanding it first.


The folk theory of democracy
The common perception holds that the people elect their leaders at the polls and then hold them accountable for representing their will. The folk theory is appealing because it puts the will of the people and their interests at the heart of government. Sovereignty resides with the people who control the agenda. Voters act as government watchdogs to enforce shared values and curb abuses. Voters correct their mistakes or punish failure at the polls by changing governments, while rewarding competence with continued time in power.

My guess is that many readers would at least suspect that the there’s something not quite right with the folk theory. For example, many people believe that one or both parties and the will of the people are often or usually co-opted by special interests backed by money in politics. That’s out of synch with the common perception of democracy. Those people would be correct in their suspicions.

If the current election season is any indication, most Americans are pretty unhappy with the state of affairs in their democracy. They see something wrong. So do A&B:

“One consequence of our reliance on old definitions is that the modern American does not look at democracy before he defines it; he defines it first and then is confused by what he sees. We become cynical about democracy because the public does not act the way the simplistic definition of democracy says it should act, or we try to whip the public into doing things it does not want to do, is unable to do, and has too much sense to do. The crisis here is not a crisis in democracy but a crisis in theory.”

Give that observation a moment to sink in. Don’t overlook the phrase “is unable to do.” That reflects the reality that most people (> 90% ?) don’t pay attention to politics, often can’t pay attention and are biologically too limited to understand what’s going on even if they tried:

“. . . . 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.”

From the biological point of view, that’s reality, not a criticism of people or their limitations. Almost everything in politics, if not everything, is more complex than people give it credit for. And, most if it is either at least partially hidden from the public, distorted in the name of “free speech”, or both.

It is hard to understate the role of cognitive biology and associated human behavior in politics. A&B point out that “a democratic theory worthy of serious social influence must engage with the findings of modern social science.” Although A&B’s book dissects democratic theory and analyzes mountains of science and history data from the last hundred years or so, the exercise is really about analyzing the role of human cognitive biology as it pertains to how democracy works. Our beliefs about democracy are shaped much more by human biology than political theory.

In Democracy for Realists, A&B assert that democratic theory has to adapt to the reality of what democracy is. That directly reflects the necessity of understanding human biology by analyzing the data.

Two points exemplify the case that this is about human biology first and what political theory needs to do to be helpful. The first point is that the “will of the people” that’s so central to the folk theory is a myth. There is no such thing as the will of the people. The people are divided on most everything and they usually don’t know what they want.

For example, voter opinions can be very sensitive to variation how questions are worded. This reflects a powerful cognitive bias called framing effects. Marketers and politicians are acutely aware of unconscious biases and they use them with a vengeance to get what they want.

For example in one 1980’s survey, about 64% said there was too little federal spending on “assistance to the poor” but only  about 23% said that there was too little spending on “welfare.” The 1980s was the decade when vilification of “welfare” was common from the political right. Before the 1991 Gulf War, about 63% said they were willing to “use military force”, but less than 50% were willing to “engage in combat”, while less than 30% were willing to “go to war.” Again, the overwhelmingly subjective nature of political concepts is obvious, i.e., assistance vs. welfare and military force vs. combat vs. war. Where is the will of the people in any of this? If it is there, what is it?

Serving the will of the people under the folk theory of democracy is often hard or impossible because there’s often no way to know what it is.

The second point is that voters usually don’t rationally hold politicians accountable for failure or reward them for success. People don’t logically distinguish success from failure. A&B point out that politicians are routinely voted out of office for things they cannot logically be held accountable for. For example, droughts, floods and an increase in shark attacks (yes, shark attacks) routinely cost incumbent presidents significant numbers of votes.

On economic issues, voters only consider a few months leading up to an election to decide if a president or party has done well. Data analysis suggests that if the 1938 recession had occurred two years earlier, FDR would not have been reelected and the New Deal would have ended. Similar “myopic” voting in the 1930s occurred in other countries and ideology had nothing to do with it. Perceptions of success and failure dominated voting in response to the Great Depression, not anything else.

That voting behavior contradicts the notion that voters rationally reward success and punish failure. In other words, politicians have little incentive to adhere to the folk theory. They know that their own success and failure can easily depend on things outside their control. That’s another key aspect of the folk theory that the data blows to smithereens.

If democracy is so strange, then what’s the point of doing more research? A&B give compelling reasons. They argue that “the mental frameworks” that both liberals and conservatives employ can be defended “only by willful denial of a great deal of credible evidence . . . . intellectual honesty requires all of us to grapple with the corrosive implications of that evidence for our understanding of democracy.”


Social identity & flawed fixes
Collectively, A&B see the data as showing that most voters vote less on policy preferences or ideology, and more on who they are or their social identities. For most voters, social identity shapes most thinking and voting behavior. That largely “reflects and reinforces social loyalties.”

A&B observe that our flawed perception of democracy led to failed remedies to reform it. Such fixes, including term limits and state level ballot initiatives, often undercut what people want from their democracy. Instead of acting to make democracy fit the theory, “more democracy” fixes that voters keep trying usually shift power to organized special interests. That outcome is precisely what voters did not want.


Why understanding democracy is critical
The point is clear. If you don’t understand how and why democracy works, you can’t change what you don’t like about it. Therefore, go figure out what democracy really is, not what one thinks it is or should be. A&B have gone a long way toward pointing out how and why it works. However, solutions to democracy issues are not clear. It may require years of empirical trial and error. Despite the surprising nature of democracy, A&B point to a more rational understanding of how things work. That is encouraging. The disappointment is that solutions are not obvious.

How Minds Can Change

Flower of a carrion plant 

“. . . . 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.” -- Democracy For Realists: Why Elections Do not Produce Responsive Governments, Christopher H. Achen and Larry M. Bartels, 2016



The New York Times reports that increasing numbers of people approve of the president’s handling of the coronavirus epidemic despite his obvious failures and lies. Polling from last week indicated that approval by independents rose by 8% from early March, and Democratic approval was up 6%. What is extremely important for understanding the cognitive biology and social reality of politics is what effect this new perception of a false reality is having on the minds of some people whose minds have changed.

The NYT writes this about one person who changed his mind and the related social phenomenon:
“Justin Penn, a Pittsburgh voter who calls himself politically independent, favored Joseph R. Biden Jr. in a matchup with President Trump until recently. But the president’s performance during the coronavirus outbreak has Mr. Penn reconsidering. 
‘I think he’s handled it pretty well,’ he said of the president, whose daily White House appearances Mr. Penn catches on Facebook after returning from his job as a bank security guard. ‘I think he’s tried to keep people calm,’ he said. ‘I know some people don’t think he’s taking it seriously, but I think he’s doing the best with the information he had.’ 
Although Mr. Penn, 40, said he did not vote for Mr. Trump, his opinion of the president has improved recently and he very well might back him for a second term.  
‘There are people who haven’t even heard Trump that much, while the rest of us have been obsessed,’ said Matt Grossmann, director of the Institute for Public Policy and Social Research at Michigan State University. ‘Those people are paying attention and seeing Trump a lot.’ 
Every modern president has seen their approval surge after significant national crises, although those bumps have diminished in size in recent administrations, as the country’s politics became more polarized. President Barack Obama gained just seven points after U.S. forces killed Osama bin Laden in 2011.”

Two points stand out. First, Mr. Penn sees presidential competence in the press conferences. He is oblivious to the underlying reality of the president’s incompetence, lies and self-centered arrogance that dominated at least until about two weeks ago. The president, his administration and supporters like Fox News say nothing whatever about the real reality of the situation. The degree of incompetence the president has displayed so far is buried.

Those buried facts are completely out of mind. Penn’s comment, ‘I think he’s doing the best with the information he had’ is clearly false, but that is completely unknown to him. Penn’s false perception of reality spills over to and changes his broader perception of the president. He now considers voting to re-elect the president. That is human cognitive biology on display. It is not rational, but it is both human and fairly common.

Second, the president is taking advantage of a crisis by not acting like the bumbling jackass he usually is. Someone on his staff finally got through to the president as somehow got the president to stop being his normal rancid self. He has toned his narcissism and stupidity down enough to be able to simply harvest the spontaneous goodwill that is inherent in national crises. Human cognitive biology and social forces lead many people to support a president they would not otherwise support.

All an incompetent, uncaring leader has to do to harvest that gift of human goodwill in time of crisis is appear to be something close to competent and caring. People’s minds will do the rest and unconsciously shift personal sentiment from neutrality or opposition to support.

DANGER DANGER

With all the concerns surrounding Covid 19, with all the people in the U.S. suffering from TDS, with all the concerns about the Environment, everyone is missing the biggest danger to our mental and physical well being that exists out there:

WE CONSUME TO MUCH


WE put ketchup on fries, hot dogs, hamburgers, mac and cheese, and EGGS for crying out loud!
I have seen people squirt SO much ketchup on their food they lose the taste of the food they are eating.
WHY?
Is Ketchup an addictive drug? Habit forming? Pretty?

Why Doctors Are Saying You Should Stop Eating Ketchup Immediately

In fact, a normal bottle of Heinz ketchup contains the equivalent of 33 tablespoons of sugar, which looks like this in a standard bottle.

7 Reasons Why You Should Never Eat Ketchup

Don't assume I want that red s*it with my fries.

THAT'S JUST, LIKE, MY OPINION, MAN

Ketchup Is a Garbage Condiment and You're a Moron if You Use It


It’s Time To Talk About How Awful Ketchup Is

Tell your tastebuds to catch up.

OK, so ketchup is hands down the shittiest condiment ever. This thick, red, vinegary, sludge has plagued some of our favorite meals.

Another Increment in Mind Reading Technology


For the wonks in the crowd


In recent years, an area of research called brain-machine interface (BMI) technology has made incremental progress in reading minds and translating that into useful outcomes. A technical report in Nature Neuroscience describes another incremental improvement, namely an increase in the speed and accuracy of reading minds using electrodes that set on the surface of the brain.

The paper describes the state of the art like this:
“In the last decade, brain–machine interfaces (BMIs) have transitioned from animal models into human participants, demonstrating that some amount of motor function can be restored to tetraplegics—typically, continuous movements with two degrees of freedom. Although this type of control can be used in conjunction with a virtual keyboard to produce text, even under ideal cursor control (not currently achievable), the word rate would still be limited to that of typing with a single finger. The alternative is direct decoding of spoken (or attempted) speech, but heretofore such BMIs have been limited either to isolated phonemes or monosyllables or, in the case of continuous speech on moderately sized vocabularies (about 100 words), to decoding correctly less than 40% of words.”
A BBC article summarizes the results like this:
“Scientists have taken a step forward in their ability to decode what a person is saying just by looking at their brainwaves when they speak. They trained algorithms to transfer the brain patterns into sentences in real-time and with word error rates as low as 3%. Previously, these so-called "brain-machine interfaces" have had limited success in decoding neural activity. The earlier efforts in this area were only able decode fragments of spoken words or a small percentage of the words contained in particular phrases. Four volunteers read sentences aloud while electrodes recorded their brain activity. The brain activity was fed into a computing system, which created a representation of regularly occurring features in that data.”
As usual, there are cautions to consider. First, the electrodes need to be placed on the brain. That is highly invasive. Second, it took a lot of electrodes to attain high word reading accuracy. Third, the decoded speech was spoken, not read from text, and limited to 30-50 sentences with a 250 word vocabulary.

What was extremely interesting was the ability of the BMI and software to learn. The word decoder they used was not just classifying sentences based on structure because accuracy increased by adding new sentences that were not used in the original tests. That data was interpreted to mean that the machine interface can identify single words, and not just whole sentences. If that is true, then it could be possible to decode sentences never encountered in a training set. The authors commented: “Although we should like the decoder to learn and exploit the regularities of the language, it remains to show how many data would be required to expand from our tiny languages to a more general form of English.”

When the computer system was trained on brain activity and speech from one person before training on another, the decoding results improved. That was interpreted to mean that the technique may be transferable across people.

Obviously, this line of research will be pursued. It is too important to not pursue it.


Why this could be important
It is not clear how far mind reading technology can progress. Research over the next ~10 years should start to clarify what inherent limits, if any, there will be in how far it can progress. If one day it is possible use machines that can read minds without invasive procedures, the impact on society could be enormous. For example, people testifying in court probably would not be able to lie and deceive nearly as well as they can now. In theory, the mind could be contradicting oral lies and deceit. Politicians making statements to the public could also similarly be fact checked in real time for lies and deceit.

The thought experiment is this: What is going in in your mind when you lie to someone? How can you really know all that is going on up there in brainlandia? Specifically, you may not consciously think of the lie itself, but your unconscious mind by be thinking, ‘that's a big, fat whopper I just told’. If that turns out to be true, or even if your conscious mind cannot help but think, ‘that's a big, fat whopper I just told’, imagine how different the world would probably be.[1]

For better or worse, this line of research will continue. We will find whatever impassible limits there may be. If there are none, then mind reading machines just might transform the world in one of at least three ways. First would be a world of far less lying and deceit by rich and powerful people and by crooks and liars, more civility, and more widespread prosperity and well being. Second, would be about the opposite. Third would be something in between.


Footnote: 
1. Yes, I know. Many people, maybe most, will instantly and strongly object to such an outrageous intrusion on their privacy and maybe even their freedom. That is a legitimate concern. That is why one wants to live in a civilized democracy that operates under the rule of law and social comity. We all know what will happen if mind reading technology is in the hands of demagogues, tyrants, murderers and kleptocrats. They will use it against political opposition, not themselves.
