Nuts have been with us, always

I am on the email list for Literary Review, but they mostly now just contain links to old reviews from their archive.  This one, though, by the late John Mortimer in 1997, talking about a sensational defamation trial in England in 1918, is very amusing.  Not sure that I have heard of the Pemberton Billing trial before.  Some extracts:
Reference was made throughout the proceedings to a mysterious German ‘Black Book’, which was said to contain the names of 47,000 prominent British homosexuals, lesbians and secret agents working for the enemy. The names included, it was said, Asquith, Margot Asquith, Lord Haldane and many others of the great and good. When a Mrs Villiers-Stuart (later imprisoned for bigamy) shouted, from the witness box, that the judge’s name was in the book, the proceedings reached a level of insanity beyond anything achieved by Mr Justice Cocklecarrot....

....Decadence, however that pejorative word is defined, is by no means synonymous with homosexuality.

Noel Pemberton Billing MP, of course, was sure that it was. He had been an actor, a barrister, the inventor of a ‘self-calculating pencil’ and a ‘flying boat’ which failed to take off. He had founded the Vigilante Society with an Admiral’s son called Henry Hamilton Beamish who believed that Britain was ruined by ‘Jewalisation’ and that the Jews were responsible for a quarter of the casualties in the war. The Vigilantes published a paper called the Imperialist, which announced ‘the existence in the “Cabinet Noir” of a certain German prince, a book which contains reports from the agents ‘who have infested this country for over twenty years’, agents spreading such debauchery and such lasciviousness as only German minds can conceive and only German bodies execute’.

Billing was anxious to spread his beliefs, not only to Parliament and the Press, but in the Courts of Law. His opportunity came when a private production of Oscar Wilde’s Salome, a play banned from the public by the Lord Chamberlain, was proposed. The Vigilante carried a paragraph mysteriously worded ‘The Cult of the Clitoris’ and went on: ‘To be a member of Maud Allan’s performances of Salome one has to apply to a Miss Valetta of 9, Duke Street, Adelphi, WC. If Scotland Yard were to seize the list of members, I have no doubt they would secure the names of several of the first 47,000 [in the Black Book].’ Maud Allan charged Billing with criminal libel and he decided to defend himself at the Old Bailey.

Mr Justice Darling, a small, dandified figure, much given to flippant little jokes at which the Court was expected to laugh heartily, was caricatured by Max Beerbohm wearing a black cap with bells on it. He allowed the loud-voiced Billing, who stood with his monocle fixed in his eye and his arms crossed, to dominate the proceedings. Hours were spent discussing the contents of the Black Book which probably only existed in the fertile imaginations of Billing, his mistress Mrs Villiers-Stuart, and some other dubious witnesses....
The tone of the trial was further lowered by the evidence of the loathsome Lord Alfred Douglas, who attacked Wilde in general and Salome in particular. He also said that prime ministers, judges and ‘greasy advocates’ all conspired to ‘support perverts’. The judge and lawyers seemed too innocent for any such task. They had great difficulty in understanding the word ‘clitoris’ and the QC for the dancer-actress Maud Allan, apparently hearing the word ‘orgasm’ for the first time, asked if it meant some sort of unnatural vice.

I am reminded somewhat of one Graeme Bird, too.  

Update:  Something else has occurred to me:   our current nutty Right wing conspiracists are decidedly lacking in numerical specificity, compared to their predecessors.  Joe McCarthy's list of subversives was either 57 or 205, but it was a very specific either way.  These days, we just have to wonder how many are in Washington's Deep State: wingnuts don't cite a number, as far as I know.  Disappointing.

Yes, ban it

Interesting article at The Conversation asks the question whether pro-anorexia web sites should be banned or criminalised.

Not sure 100% sure whether criminalisation is the best response to removing them off the net, which should be the first priority, but can't say that I would have a moment's concern about an attempt to criminalise them. 

The article doesn't agree, and runs the odd argument that many women (well, it is much more common with women) end up at these sites because they already have an eating disorder and are looking for support.   But, of course, it's exactly the wrong sort of "support" that these people will get from a "pro" site.

Free speech ninnies can get lost, as far as I'm concerned:  Western society is not going to collapse because of legal interference with some websites (or their owners) who are clearly encouraging self harm of otherwise healthy people which is likely to end in death.   

A dreamy post

NPR has a post up talking about the scientific understanding of dreams, and it opens noting that Freud is not doing well in science circles:
"For 100 years, we got stuck into that Freudian perspective on dreams, which turned out to be not scientifically very accurate," says Robert Stickgold, a sleep researcher and associate professor of psychiatry at Harvard Medical School. "So it's only been in the last 15 to 20 years that we've really started making progress."
Yet further down, it has a peculiar claim:
A number of Freud's observations about dreams are still relevant, even if his interpretations of them are less than scientific.
For example, he observed that certain dream elements are common, if not universal. Teeth, for example.
"A particularly remarkable dream symbol is that of having one's teeth fall out, or having them pulled," Freud wrote in A General Introduction to Psychoanalysis. He goes on to say that's usually a symbol for castration "as a punishment for onanism." The castration explanation may be off base, Baird says. But problems with teeth are, indeed, something many people report in their dreams. "It's weird," he says. "What has that got to do with anything?" Baird suspects we share many dreams like this because we share the same nervous system design, and many of the same anxieties.
I say peculiar, because I don't recall ever having an odd tooth related dream.

I would have thought that the more useful common dreams to mention would have been:   being accidentally nude, or somehow exposed, in public;  the "what - I have no idea how to answer these exam questions"  dream; and the "I can levitate if I really concentrate" dream.   All of which I think are common.  (OK - not certain about the last one - I think flying dreams are pretty common, but I have found that some people claim never to have had one.   The run of odd levitation dreams I was having really ran for a long time - and oddly, some involved trying to prove to other people that I was not dreaming.  Hence, waking up from them was particularly annoying, because in the dream I thought I had the video proof that would satisfy everyone, including myself, that it was real.)

Anyway, I like how the article notes this:
Dreams may be so hard to pin down scientifically because they are so closely related to consciousness, a concept that has bedeviled scientists and philosophers for centuries.

We all somehow know we are conscious. But it's been difficult to define precisely what consciousness is, let alone determine how it is generated by the brain.

Pleb who can't handle the truth

I don't usually bother much with reading Andrew Bolt's persistent foolishness on climate change, whereby other mere polemicists (Delingpole, Monckton) and a handful of contrarian science types are taken as knowing the Truth that All Other Scientists, Their Professional Bodies, and 90 Something Percent of Governments Just Won't Admit.

But I did today, and noticed this in comment with some amusement:

Heh.

Peter, Peter.  If you knew not to listen to Bolt, you wouldn't need correcting.

Back to McArdle

I see Megan McArdle's "let's not blame governments for the Grenfell fire - they were just acting as libertarians like them to act " column at Bloomberg has now reached nearly 2000 comments, with probably 95% of them ridiculing her.

As I noted in my previous post, it was pretty disingenuous of her to concentrate only on the issue of the cost of retrofitting fire sprinklers, when the more obvious problem was regulations regarding the cladding.   Does she really have to be reminded that if the cladding didn't burn, the entire building might not have gone up and the issue of sprinklers could have been much less important?

In any event, even her argument about sprinklers is looking shaky for two reasons:

a.   it is starting to look like the cost of retrofitting them is actually not as high as I would have guessed:
The British Automatic Fire Sprinkler Association (BAFSA), the trade body for the fire sprinkler industry, said retrofitting Grenfell Tower with sprinklers might have cost £200,000. This is the figure for installing a sprinkler system but does not include potential maintenance fees or costs associated with the wider redevelopment of a building.
And another Council has already decided to retrofit 25 high rise blocks at a cost of ten million pounds.

b.   McArdle's argument - that every dollar governments spend on sprinklers would divert it from other life preserving things like hospitals - conveniently, and in a very libertarian/small government way, ignores government's ability to raise extra money for worthwhile things by raising extra taxes.  Oh noes - we can't have that.

Now, this is not to deny that there might still be a legitimate argument to be had, by appropriate experts, about cost benefit analysis of retrofitting sprinklers to certain buildings.  

But clearly, McArdle's position was to start from a presumption not only that it's always best to leave it to the market to decide (a silly thing to be talking about when these residents did not have market power - and also, to the extent that you could say the market, in the sense of builders quoting for a job, came up with a disastrous result on the cladding in this case); but that you should never be too tough on government for making decisions on a cost benefit basis, even when there is no evidence around that cost benefit was considered in this case.   (And, that in fact, money saved on public housing and other Council functions was given back to the well off in the Council!)

 

Skeptic win?

Back in 2010, and again in 2014, I posted about the very interesting parapsychology experiments of Daryl Bem, and it's time to look at how the work is viewed now.

Not all that well, apparently.  Slate ran a lengthy article about it a couple of weeks ago, but I think this commentary on it (taking a quite sympathetic approach to Bem personally) is better reading.

The argument is that it was all a problem with statistical analysis, and that it really set off the reproducibility crisis in the whole field of experimental psychology.  

The lack of replication is, obviously, a concern; but I wish I understood statistics a bit better to understand some of the arguments that rage about their appropriate use.

Brisbane's wooden high rise

I posted about this plan to build a 52 m high wood office building in Brisbane recently, and now The Guardian has a lengthy report about it.  (Probably prompted by renewed interest in how easily buildings can burn.)

While I think it's a very interesting project, there's one issue I have my doubts about - the claim that this type of wood building is definitely healthier for the workers.   The reason - the wood product used is actually a cross laminated material - timber sheets glued together - and I am curious as to whether the glue used slowly leaks any chemical into the air over time.

I could well be being overly cautious here - but it just seems to me that its likely to emit some smell, at least early in its life.

When Presidents tweet

Several American sites are noting that Trump's tweet re North Korea:
While I greatly appreciate the efforts of President Xi & China to help with North Korea, it has not worked out. At least I know China tried!
 is dangerously ambiguous.  As New York Magazine writes:
But if Trump’s tweet is just mindless bluster, that hardly makes it less unnerving. In their joint military exercises, the United States and South Korea have rehearsed preemptive strikes against North Korea, ones designed to kill Kim Jong-un before he has a chance to press the proverbial button. Arms-control expert Jeffrey Lewis has warned that the implication of these exercises aren’t lost on Pyongyang: Kim knows “he has to go first, if he is to go at all.”

Just because savvy news consumers in the United States are comfortable assuming that Trump is merely talking trash doesn’t mean that North Korea is. In April, the president suggested that the day Beijing’s efforts to rein in Pyongyang failed would be the day that America took action against Kim Jong-un’s regime.

“Well if China is not going to solve North Korea, we will. That is all I am telling you,” Trump told the Financial Times.

The fact that the American president is an emotionally volatile reality star — who publishes his foreign-policy musings directly to the internet — has always been dangerous. In the context of a military standoff with a nuclear-weapons state, it may prove fatally so.
They are right - and you would have to be completely foolish (as Trump supporters are) not to see the impropriety and danger in this idiot President tweeting to the world.

A happy Hollywood story

Here's a long interview with all-grown-up (and rather plumper and hairier) actor Haley Joel Osment.   As the interview makes clear, he had really good experiences in making a couple of very high profile movies as a child - and it sounds like sensible parents were an enormous part of that.

Of course, the fact that he worked with Spielberg on AI - a movie Osment and the interviewer both love (I think it is very under rated) - makes me particularly interested in him.

Many more micro satellites on the way (and mobile phone talk)

Foreign Correspondent moved away from its normal political/social emphasis last night to look at the growing industry of micro satellites, and it was pretty fascinating.

I liked the way the guy from Planet explained how the origin of the idea was just to put mobile phone technology into space:  he emphasised the technological marvel that the commonplace mobile phone is these days, just as I like to do.

I am itching to buy a new mobile phone at the moment, and I am contemplated being unfaithful to Samsung.   (I may need to visit the confessional.)   The Moto G5 Plus seems to have everything I want in a mobile phone - except, I admit, the wonders of a beautiful Samsung AMOLED screen.

To get all that I want, ideally, I would buy a $650 Samsung A5.   But for $250 less, the Moto one has NFC - needed for using your phone to make paywave payment (an odd exception from Samsung J5 and J7, which cost the same or more as the G5 Plus), and a gyro sensor (which I understand is important if you want to use it to live in a VR world - and also not in the equivalent priced Samsung models.)   But the A5 does have a gorgeous looking screen, and is quite waterproof.     (Note that I have ever dropped a phone in the toilet - yet.)

Bizarrely, I have noticed that the cheap Samsung J range has this weird thing where some of the cheaper models have an AMOLED screen, and even my two year old cheapo J1 has NFC;  but the top end of the J range (J5 and J7) don't have either of these.  Hence Samsung are still making things rather confusing with the features in their model range.

Horse fat? (Actually, a potato post)

Some unexpected information in The Guardian about Belgian chips (my bold):
Whether eaten with mayonnaise or taken au naturel, the Belgian chip is up there with chocolate, beer and the national football team in the nation’s psyche. No public square is complete without a frietkot, or chip stand, where sellers swear by double frying bintje potatoes in beef or horse fat to achieve the ideal combination of a succulent centre and crispy exterior.
I don't much like horses:  I'd just as soon they stayed out of any chips I might be eating, as well.  If ever I get to Belgium, that is.

Speaking of potatoes, I recently made nice sautéed potato with fennel seeds thrown in.  (Boil cubed potato first, for only about 3-5 minutes, then sauté in non stick frying pan with a fairly small amount of olive oil, with fennel seeds and salt, 'til crisp outside. Delicious.  And not a horse to be seen.)

And finally:  after some resistance from my wife,  who doubted I would use it, I acquired a potato ricer a few months ago, for use in making mashed potato.  One of these things:


While I wouldn't go so far as to claim that it has changed my life (I do, after all, only mash potatoes about once a month), I have to say that using a ricer gives extremely pleasing results.   Even before this, I made the best mash in the house;  now the quality is uniformly great - so much so that I sometimes worry that it's so smooth that it seems manufactured.  I still love it.

Why repeating lies makes them seem true

Vox talks about the "illusory truth effect", which surely has become something dangerous in the world of social media and other forms of echo chamber:
Psychological science consistently finds when a lie gets repeated, it’s slightly more likely to be misremembered as truth. It’s called the “illusory truth effect.” It’s a tendency the whole news media — as well as consumers of news — should be wary of. And it’s a reason not to give notorious bullshitters such a substantial spotlight. Especially bullshitters whose lies hurt others and whose lies have a track record for virality....

The illusory truth effect has been studied for decades — the first citations date back to the 1970s. Typically, experimenters in these studies ask participants to rate a series of trivia statements as true or false. Hours, weeks, or even months later, the experimenters bring the participants back again for a quiz. 

On that second visit, some of the statements are new, some are repeats. And it’s here that the effect shows itself: Participants are reliably more likely to rate statements they’ve seen before as being true — regardless as to whether they are or not. 

When you’re hearing something for the second or third time, your brain becomes faster to respond to it. “And your brain misattributes that fluency as a signal for it being true,” says Lisa Fazio, a psychologist who studies learning and memory at Vanderbilt University. The more you hear something, the more “you’ll have this gut-level feeling that maybe it’s true.” 

Most of the time this mental heuristic — a thinking shortcut — helps us. We don’t need to wrack our brains every time we hear “the Earth is round” to decide it’s true or not. Most of the things we hear repeated over and over again are, indeed, true. 

But falsehoods can hijack this mental tic as well.

Hating regulations because they're regulations

I know that it is actually probably more complicated than it may first appear - the matter of what claddings are allowed to be used on high rise buildings.   I say this because I was reading the CSIRO's guide on the matter, produced in 2016, which can be found via this page.

Nonetheless, I find it difficult to not marvel at the stupidity of the libertarian response to the Grenfell fire, with people like Stoat (who is on the right side of climate change, but otherwise likes to take contrarian positions on various things) saying things like:
But buildings *are* very heavily regulated. They are not “deregulated”. This can just as easily be seen as a failure of the “regulate everything and all will be well” approach
And he cites Tim Worstall:
So, layer upon layer of intrusive regulation and government made this happen.
The solution is more layers of intrusive government and regulation. That’ll work, won’t it?
As someone says in response to Worstall:
I don’t know, but what do you suggest as an alternative? Fewer fire regulations? No fire regulations?
And someone back at Stoats writes:
Timmy’s argument is ludicrous: the Graun describes how the designers and builders failed to comply with the building regulation requirement that “the external envelope of a building should not provide a medium for fire spread”, and other factors contributed to the death toll. Timmy jumps to:
“So, layer upon layer of intrusive regulation and government made this happen.”
False as the regulations are not “layer upon layer”, they have repeatedly been revised, tested, and reexamined in relation to experience, as well as getting watered down by dogma against regulation.
Ludicrous as, by Timmy’s argument, regulations against murder make murders happen.
The other ludicrous line that some on the Right are running is that the building was only clad in flammable cladding because of Green/climate change regulations for insulation.    (Some have been trying to bring EU regulation into it too - which hardly makes any sense if it is true that Germany does not allow the use of this material on its buildings.) 

This was pretty quickly extensively fact checked and found to be the misleading furphy that one might expect it to be.  It seems that the Right has become so stupid as to not even want to admit that insulation on buildings is an inherently good thing for, you know, making a residence more comfortable to live in.   (The link notes how the Grenfell tower had windows that for safety reasons could not be opened far - making it hot in summer.  And I assume that any residence in London benefits from insulation in winter.) 

This is a case where common sense makes sense:   this is a problem of inadequate/poorly designed/poorly enforced regulation.   It's nonsense to take a line that it's due to over regulation.



Bad reasons for eating animals

I was watching the 7.30 report on dog meat being eaten in Bali (a relatively recent cultural innovation, apparently), and I annoyed to see one old Balinese guy say he eats it because it keeps you healthy, especially in winter.

What is the name for the belief that eating particular animals is particularly good for you, in certain ways?   Most notoriously, it pervades Chinese medicine, and other Asian cultures, but I suppose it hangs around in lots of other continent's native cultures too:  the idea, in a generic sense, that eating a particularly strong or fierce animal (or a particular organ of it) will pass on some of its character to the eater.

It kind of drives me nuts:  a quasi spiritual idea that has been responsible for the endangerment of so many species for completely spurious reasons.  (Or is it a case of a placebo effect meaning it actually does help people?  But even if it is, can't they move onto using sugar pills instead of God knows what animal's penis, or heart, or whatever?)

I know people aren't evil for eating dogs, although my personal fondness for them means, of course, that I wish people wouldn't.  And, I know, they aren't endangered and never will be.   But if the motivation is simply because they are supposed to be particularly healthy for you - that just annoys me in particular.

Another 50 year anniversary: You Only Live Twice

Every time I see a Space X rocket landing vertically, I'm reminded of You Only Live Twice - the first Bond film I saw as a child , at a drive in, and it remains a Bond favourite to this day.

The Japan Times points out that it's the 50th anniversary of the movie, and has a lengthy account of Fleming's interest in Japan, which centred around the exploits of an Australian reporter, Richard Hughes, who was (apparently) transmogrified in the novel into one "Dikko" Henderson.  The story goes like this:
After less than a year in Tokyo, Hughes, sensing the imminence of war with Japan and keen to alert Australia and America to the danger, packed his own notebooks full of sensitive information and headed back to Australia at the beginning of 1941.

When the war ended, Hughes returned to live in Japan, now under American Occupation, and became manager of No. 1 Shimbun Alley, a rowdy foreign correspondents’ club situated next to the residential wing of the Soviet Embassy. The club was the meeting ground of reporters, former soldiers and spies, many of whom conducted illicit liaisons in its bedrooms.

The Cold War deepened in 1948 over the Berlin Airlift. Hughes was dismissed as manager of the club and swore never to return to it. At the same time, he started working as a foreign correspondent for London’s Sunday Times, under its foreign manager Ian Fleming, who had played a distinguished role in British naval intelligence during World War II and presided over many crucial covert operations.
Hughes now created his own intelligence network by founding the Baritsu Chapter, supposedly the Asian section of the Baker Street Irregulars, a Sherlock Holmes appreciation society first founded in the U.S. in 1934. “Baritsu” is the name given to a fictional form of martial art that Holmes is described as using to defeat his arch-nemesis, Moriarty, while wrestling with him at the Reichenbach Falls.
Hughes went on to become a double agent, fooling the KGB, and (much later) took Fleming on a boozey research tour of  Japan for the novel.

Would you buy a Nimble Dragon?

There seems to be some renewed effort from the nuclear power industry generally to push small, modular nuclear reactors.   I say this based on an interview I heard on Radio National one recent morning with what sounded like a PR person for the industry out to sell the idea.   Actual product ready to sell, though, is still not around, despite years of talking about this potential industry.

But I see in the Japan Times that the Chinese may now be trying to develop this as a market:
China is betting on new, small-scale nuclear reactor designs that could be used in isolated regions, on ships and even aircraft as part of an ambitious plan to wrest control of the global nuclear market.

Within weeks, state-owned China National Nuclear Corp. (CNNC) is set to launch a small modular reactor (SMR) dubbed the “Nimble Dragon” with a pilot plant on the island province of Hainan, according to company officials.

Unlike new large scale reactors that cost upward of $10 billion per unit and need large safety zones, SMRs create less toxic waste and can be built in a single factory.

A little bigger than a bus and able to be transported by truck, SMRs could eventually cost less than one-tenth the price of conventional reactors, developers predict.
Sure they make great mobile phones, but not entirely sure (to put it mildly) that they have the runs on the board re environmental responsibility to trust a nuclear reactor shipped out from there.

Strop it

I was at Target recently, hanging around the (mainly women's) toiletries while my daughter looked  for a possible gift for a friend, and noticed that on a "discount" shelf they had a cheap version of one of the razor blade sharpening products that I had occasionally noticed at The Razor Shop; but at $20 or $30, I hadn't ever bought one.

The Blade Buddy only cost $5, so I bought it out of curiosity.

The operative part is just a slab of rubber or silicon, I'm not sure which, with some ridged sections, and all you do is rub the razor blade upwards on it (with a bit of shaving cream for lubrication) about 15 to 20 times before shaving.  It doesn't take long.

The packaging says it works by "re-aligning" the blades, or some such, which sounds very improbable, so it was with low expectations that I started using it.

But, I have to say, I think it is working.   I did start with a new blade cartridge (a cheap 4 - or is it 5?- blade razor that Coles and Woolworths both sell), but after a week, I have the distinct impression that it feels sharper than if I hadn't used the Buddy device.

Mind you, I have been able to get about 3 to 4 weeks out of one of these cartridges anyway, so maybe it is an illusion.  But I don't think so.

When I google the topic, I see that there is actually a lot of material out there saying that these razor cleaning devices do work just by cleaning the blade, in a very similar way to the old "stropping" of a blade on a leather strap.   Makes sense.

In fact, there is also material out on the web about just using old denim to "strop" a cartridge razor.  And one guy - whose video I haven't properly watched - claims to have gotten 3 years out of one cartridge(!).  Maybe there's black magic involved...

Nevertheless, it seems clear that there is good reason to believe you can get very substantial extensions to the "normal" life of razor cartridges.    And to be honest, I don't mind the procedure:  it makes shaving more feel more, well, ritualised.  (You have to remember that I enjoy using shaving soap and a brush, too.)

Given the ridiculous cost of brand name, multi-blade cartridges, I am very surprised that this is not better known.   Certainly, I had never thought of it before - I just assumed that cartridge blades were so thin that they developed pits and holes that you couldn't do much about it.

It would seem I was mistaken. I will revisit the topic in a month or two's time...

Update:   more on using denim jeans to strop a razor cartridge.  The guy claims to be using the same cartridge for 8 months at the time he wrote that...

Ridiculous performance art

I suppose there will always be eccentrics, and/or the disturbed, who will want to create performance art involving blood and gore.   

What I find a bit more disturbing is that they can find a paying audience. 


Bruni on the state of political discourse

Bruni's column ("I'm OK - you're pure evil") about the coarsening of political discourse in the US, and in particular the dangerous role of social media in the process (something of a favourite theme of mine) is pretty good:
Over the past decade in particular, the internet and social media have changed the game. They speed people to like-minded warriors and give them the impression of broader company or sturdier validation than really exist. The fervor of those in the anti-vaccine movement exemplifies this. So did the stamina of Americans who insisted that Barack Obama was born abroad — and who were egged on by Donald Trump.

Admirers of a responsible politician or righteous cause coalesce quickly, but the same goes for followers of a hatemonger or crackpot. One good articulation of this came from David Simas, who was Obama’s political director, in a New Yorker article by David Remnick that deconstructed the 2016 election.

What people find on the web “creates a whole new permission structure, a sense of social affirmation for what was once unthinkable,” Simas told Remnick. Obama, in his own comments to Remnick, picked up that thread, saying, “An explanation of climate change from a Nobel Prize-winning physicist looks exactly the same on your Facebook page as the denial of climate change by somebody on the Koch brothers’ payroll.”

“The capacity to disseminate misinformation, wild conspiracy theories, to paint the opposition in wildly negative light without any rebuttal — that has accelerated in ways that much more sharply polarize the electorate,” Obama added. Suspicion blossoms into certainty. Pique flowers into fury.
Writing about last week's shooter of the Repbulican Congressman:
His life online reflected the goosing, goading, amplifying power of social media and the eminence of outrage in public debate. As Michael Gerson noted in The Washington Post after the shooting, today’s partisans “have made anger into an industry — using it to run up the number of listeners, viewers and hits.” Mocking and savaging political opponents have been “not only normalized but monetized,” Gerson added, and he stated the obvious, which needed stating nonetheless: “If words can inspire, then they can also incite or debase.”
