Politics & Religion / The Grip of Government
« on: March 26, 2012, 10:23:29 PM »
My take - I do not think of this as a "Dem" issue or another reason why you should fear Obama.  It may suit the conservative urge to blame the ideology of the "other side".  To find further fault with the someone you already do not like, trust, or agree with.  They have a face and a name and make an easy target for your discontent.  Too easy.

Rather this is a Big-Government-out-of-control problem.   And it would not make any difference who is in the White House.

Government is an institution.  Like all institutions, it is self-preserving.  The checks and balances are essential and must be maintained.  Otherwise the institution starts to act in its own interests.  Pure faceless mechanics.

Politics & Religion / Follow the Sacred
« on: March 19, 2012, 11:13:39 PM »
A very interesting piece by moral psychologist Jonathan Haidt - he takes an approach to the political situation that is very similar to one that I have been exploring for the last few years with regard to religiosity and mythological realization. 

http://campaignstops.blogs.nytimes.com/2012/03/17/forget-the-money-follow-the-sacredness/

Extracted from Haidt:
"Despite what you might have learned in Economics 101, people aren’t always selfish. In politics, they’re more often groupish. When people feel that a group they value — be it racial, religious, regional or ideological — is under attack, they rally to its defense, even at some cost to themselves. We evolved to be tribal, and politics is a competition among coalitions of tribes."

He trends from the left - and yet I find the core of his argument very persuasive.  It applies equally well to both "sides" of the spectrum and begins to account for why we are so enthusiastically tearing ourselves apart.   How we can possibly make sense of maiming ourselves.

Mark 9:43:  And if thy hand offend thee, cut it off: it is better for thee to enter into life maimed, than having two hands to go into hell, into the fire that never shall be quenched

As mentioned in the previous thread (Political Economics), the Harper government in Canada just dropped corporate taxes by 1.5% to 15%.  That will equate roughly to 33 billion annually given back to Canadian corporations.

Harper has recently been complaining about the 3/4 trillion sitting in corporate coffers stagnant - most enterprises sitting back during the rough economic times to hold onto their surpluses.  This break will allow them to hold even more money stagnant. 

The assumption seems to be that corporations are going to spend us out of tough times by growing, investing, and otherwise freeing up those stagnant funds.  But that does not really seem to be happening.  Like spooked consumers, they are sitting on the money to see how this plays out.  Which of course just drags out the recovery.

In the case of consumers, you can sometimes get them to start spending even when they probably should remain cautious or work hard at reducing their debt.  Corporations on the other hand are run by some of the most saavy financial types to be found.  They know better than most when to move and when to sit still (although no guarantee of good sense).  And you can expect corps to do what is best whether they get a tax break or not.

I can see the long term benefit of tax breaks - attracting more foreign business, encouraging investment and innovation, etc.  But in a stale or limping economy where the future is uncertain, I do not see why this is a good move, at least in the short term.  Why would corps start spending significantly under these circumstances?  The only real use of corp reserves seems to be the usual M&A activity that accompanies a slow economy.

So is there any reasonable expectation that lowered corp taxes will help jump start an ailing economy?

Politics & Religion / Re: Canada-US

So regardless of whether you blame the government or the corporations for the American experience, you are essentially concluding from the Canadian experience that, in general, strong regulation is needed for financial services?

Thus the need is for better government, whether or not that means less government?  Regulation necessarily means bureaucracy.

Or is there a free-market  (i.e. unregulated) solution to keep banks from doing this again?

Politics & Religion / Re: Political Economics - Canadian style
« on: January 01, 2012, 01:02:38 PM »
Tricky checking in after being away for the holidays.  Thanks to Crafty for forwarding a short reply I made on the Canadian situation.

While I am likely of another ideological stripe than many of you (judging from the rhetoric), I am far more interested in the ground truth - and good critical thinking - than odiously repeating any dogma.  Regardless of whether one personally appreciates the recent actions of our government, one can hardly attribute Canada's strong economic state to them.  There simply has not been enough time to show the consequences.

Check back in 5-10 years once the effects from the changes have filtered down through the economy.  And through the social fabric.

If you want to look at the current evidence as indication of anything, consider that the strong banking regulatory environment (established long ago by more liberal governments) is in part responsible for our solid footing.  And that we are a heavily resourced country with high international demand, particularly from Asia where we have very strong ties.  And that we in Canada have not experienced the same degree of instability because we are not as free-market based (even if you take a Friedmannian view that they are not free enough and any issues arising are due to the extant limitations) as the US.  Our relatively strong system of checks and balances has meant that we could ride this period out with less direct and collateral damage.

The Harper government only just achieved a majority last fall - they have been riding a minority government for several years - so it would be misleading to read the current signs as if their policies of the last few months are responsible.  Prior to that, the centrist (for Canada) Liberal government was in power for decades and was primarily responsible for most of the current policy and our economic position.  So if you want to find something laudable about our strength, look a bit further back in our history instead of singling out decisions made in the last 2 months.  It takes years to define a stable economic position.

Of course, one of the things the current Harper government is in the process of doing is dismantling many of those shielding mechanisms - the 67 year old Canadian Wheat Board (which buys from all wheat farmers and represents them on the international market) has just been killed off.  Harper is certainly a fan of free(r) markets and believes this change long over due.  And let's check back in 10 years and see if we are all that better off.

He is also dismantling our long gun registry (being contested by the provinces), introducing a new hard-on-crime bill (without explaining how the significant new costs will be borne - and despite the general view that the same approach has failed in the US, economically as well as socially), backing out of climate change commitments, turning away from the UN, and building up our military.

Which may sound like an attractive cup of tea - but note that he is simultaneously severely limiting debate in Parliament, raising personal taxes (as mentioned), reorganized the Senate by adding 35 new appointed senators, reducing the transparency and accountability of the government (e.g. closing committee meetings to the public watchdogs who are supposed to oversee and report on the government), dropping our detailed census (that provides facts for effective public policy), and committing the country to expensive, non-economic programs (e.g. military spending, military activity, new prisons, border security unification) without proper accounting and in the face of mounting debt. 

Note that, although the government holds majority in House and Senate, they only won 40% of the popular vote - and yet they regularly claim a mandate from the people as the justification for rushing bills through without more than cursory debate.

So before anyone including the media starts cherry-picking facts from our experience and imagining a causal relationship with our economic performance, I would encourage you to research a little deeper.

There is a bald irony present:  When our healthcare system was being referenced as a possible model for the US, most (including myself) were quick to say that Canada has a very different scale and nature.  Any comparisons would hardly be appropriate or meaningful.  But now that the actions of our current government align ideologically with a more conservative approach, Canada suddenly becomes a model for the US or proof of the value of a particular viewpoint?  That is convenient and selective, not critical, thinking.

Science, Culture, & Humanities / Re: speed of light broken

The media needs to take a cold bath.

As has been said clearly, the result is reproducible and therefore "puzzling" - and so the group at CERN have offered up their data to other groups to confirm (or deny).  The natural course of science.  The speed of light limit is a long-standing principle (if you call 100 years "long") and represents a significant challenge to the scientific status quo.  But note that nothing will fall apart or become more or less true should this result stand - even if it does turn out that neutrinos are "breaking the law", like so many revelations in scientific discovery it will simply mean developing newer and better models that account for everything we have seen to date plus this.

This is currently in the realm of "science fiction" - or at least "science speculation".

In gravitation, Newton was proved "wrong".  Then Einstein.  And I'm sure one day Hawkings will also fall to the latest and best description of gravitation.  We all know that we haven't been able to include gravitation properly into the unified theory.  It may be because there is some subtlety about space-time that we haven't accounted for.  This may help us uncover it.

It's exciting frankly.  I don't know why the media portrays it as threatening.  No scientist thinks that they know the ultimate truth about life the universe and everything.  Science is a series of models - not some stranglehold on truth about reality.  Any scientist who believes otherwise should be shown the door.  In fact, challenging existing canon is a natural consequence of what every critical thinking scientist should be doing - albeit not gratuitously.  It's good science (remember, this is not a religion, despite our tendencies).

In this circumstance, unambiguously, the first position taken is that they must be making systematic errors and they want another group to check it independently.  Good scientific process.  Until that is done, this is like a UFO sighting - possibly something revolutionary but much more likely something quite banal and well understood - a mistake in scientific preparation and/or analysis.  Occam's Razor at work.

The media is like some crazed terrier who goes barking madly up and down the hallway every time it hears a floorboard creak.  You need a new dog.

Update:  From the UK Guardian http://www.guardian.co.uk/science/2011/sep/23/physicists-speed-light-violated:

Quote
Professor Jim Al-Khalili at the University of Surrey said it was most likely that something was skewing the results. "If the neutrinos have broken the speed of light, it would overturn a keystone theory from the last century of physics. That's possible, but it's far more likely that there is an error in the data. So let me put my money where my mouth is: if the Cern experiment proves to be correct and neutrinos have broken the speed of light, I will eat my boxer shorts on live TV."

Ooooooh - thinking about time travel just hurts the head.  And the funny thing is that equations treat time and space the same - so why would it be that we can imagine teleporting through space so easily but time travel gets complicated so quickly?

Anyone see the low-budget scifi called Primer?  Available on NetFlix - a great film considering it was made for $7000.  A great film regardless.  But the way it makes your head hurt.... that seems so typical of time travel.

That aside - the thing to keep in mind about that article is that it applies to quantum states, not elephants:

Quote
“You can send your quantum state into the future without traversing the middle time,” said quantum physicist S. Jay Olson of Australia’s University of Queensland, lead author of the new study.

In ordinary entanglement, two particles (usually electrons or photons) are so intimately bound that they share one quantum state — spin, momentum and a host of other variables — between them. One particle always “knows” what the other is doing. Make a measurement on one member of an entangled pair, and the other changes immediately.

So you have to limit your imagination to what you know about quantum states - the Star Trek analogy involving Scotty doesn't apply so readily.

What does that get anyone?  That's where the imagination really comes in and I must say fails me admirably.  What kind of technology could you build with it?  Undetectable signals (since they aren't present for the "middle time")?  Feedforward loops (mechanisms that track states in the past in order to synchronize themselves with past events)?  Past-time sensors that send data to a future receiver?

Basically they are quantum "echoes from the past" - kind of like a camera recording current events so they can be replayed later.  But you aren't replaying them, you are receiving the signal directly through time.

Maybe.... you could put sensors in an environment where they wouldn't be able to send a signal or record either (for some reason) and have them instead beam the signal into the future.  For example, measuring state within a device that is exploding (and would overwhelm a signal with EM or destroy a stored signal).... now why would you want to do that?

OK - how about back to quantum encryption?  You encode data and send it into the future - it is effectively gone until that later time when it arrives and can be recaptured.  Then it can be retransmitted forward again and the information disappears.   That might be a good way to hide information.

Really, since you are stuck in quantum terms, the only thing worth considering is information - data - communications and computation.

Anyone else have a better concept for using time entanglement?

Science, Culture, & Humanities / Mythology and science - a commentary
« on: January 24, 2011, 08:07:41 AM »
As it happened, I was reading an analysis of the role  of mythology in scientific undertakings (a personal favorite of mine) and found a passage that exemplified some of what I was just referring to in the previous post:

Quote
While many myths simply try to give form to our own past, others are intended to be both descriptive and prescriptive. Like laws of nature, they must hold true everywhere and for all time. Their adherents can brook no alternative perspective. The tendency to settle prematurely on a particular outlook is exacerbated in the guild system of health care. The practitioner must not be seen as equivocating, and the field as a whole must not be seen as thoroughly divided in its core orientation. Science is unitary, and in order to appear scientific, at least provisional assent must be yielded to a unitary vision. Such a unitary vision is likely to start out as largely myth.

The aspirational social sciences have a particular problem here because it is so difficult for a proposition to rise to the level of established fact or theory. Indeed one can sympathize with political scientist Clinton Rossiter who declaimed at one point: “I believe this so strongly that it almost becomes a fact.” Instead these fields move forward by consensus. If reasonable consensus is achieved within a discipline, then provisional scientific validity is simply claimed. The Diagnostic Statistical Manual of psychiatry is perhaps the best exemplar of this process at work. The science behind it is meager, but that becomes a non-issue in the face of general acquiescence to the DSM formalism. What we have here, plain and simple, is myth masquerading as science.

We actually have a ready diagnostic to distinguish myth disguised as science from actual science. If a particular proposition brings forth strong emotions in its defense, then we are dealing with myth. One can be sure that no one mounts the ramparts on behalf of Newton’s Laws of Motion.

Active social mythology is not given significant attention in my view.  But that's another post another time.

Hi - Tricky parachuting in for a glib follow-up or two - I don't peruse the forums too much for lack of time.  But I see that Crafty et al have brought some interesting points to bear.  And he just quoted me - so...

Re: quantum effects - as mentioned, the interesting nature of QM doesn't really play at the macroscopic (read "human") scales.  Various attempts have been made to see QM happening at longer scales - and some interesting things have been seen - but only under very carefully crafted circumstances.  It is largely wishful thinking (so far) to speculate QM has any large-scale relevance day-to-day. 

And science may yet prove otherwise - that's what is really enjoyable about the endeavor.

Much more likely is that human perception and cognition are responsible.  Without impugning anyone's intentions, we often find ourselves experiencing a more subjective reality than we like to admit.  Unless experiments are constructed very carefully, "human effects" creep in almost inevitably.   People often talk about bias - but frankly, that's not even a question in my view - we see what we want to see as matter of course.  Seeing otherwise takes a tremendous amount of discipline and careful process.

A healthy amount of skepticism is warranted - and in fact required by the methodology.

Most of what is being discussed here revolves around very human processes and highly complex systems.  Almost anything have to do with human process is overloaded with uncontrolled influences, many of them cognitive and complicated by socio-political views.  It's pretty difficult to do "hard science" (in the sense of physics) in those circumstances.  Take homeopathy and chiropractic as an example - while both have been next to impossible to prove as beneficial, there are wide-spread reports of benefit.  People have positive experiences and effects that they attribute to the practices.  So what is "true"?

Just try to separate out the human effects from the controllable processes.  It has led to all kinds of strife and struggle - and it is largely because scientific methodology is very difficult to apply reliably in those "soft" contexts".  Particularly as we are not able to isolate the influence of belief and the mind on the body's response.  The placebo effect is the classic case that underscores this influence.

So if you are pointing at science pertaining to anything with a significantly human context, then I fully expect it to be pretty squishy and subject to revision.  Quite likely endlessly.

Similarly, if you are talking about complex systems - such as the global climate - you had better be prepared to be frustrated and challenged.  Not only are there an incredible number of different influences on the system (science often relies on reductionist methods), none of which can be easily tested for, but many of them are highly non-linear.  Which is why we are so bad at predicting the weather on a day-to-day basis.  Or the stock market.  Which isn't to say we know nothing about them.

Thus it doesn't surprise me much to hear that things are not quite the way we thought they were - especially regarding science around soft and/or complex systems.  And you don't have to resort to QM effects to explain it.  Occam's razor.

Meanwhile, I don't think you'll be finding the accuracy of the measures of the speed of light in a vacuum will be slowly falling in the near future.
