Tree and Vine: An Allegory of Attenuated Parasitism.



The town of Forrest has been around for centuries. It’s the kind of place where sons inherit their father’s businesses and nobody can remember when things were too different. The town has always been so small that it supported only a single shopkeeper; the current proprietor of this humble store is a tall and stable fellow named Woody, the descendant of a long line of tall and stable men just like himself who have worked hard to build and maintain what’s always been a social focus of Forrest.

Small towns like Forrest might seem peaceful to visitors, but internally there are the inevitable gripes, grievances, and grudges. For example, a recent family feud over the inheritance of their grandfather’s property has split Woody from his cousin Trey. As a consequence, Trey has recently opened a competing store directly across the street from Woody thus ending Forrest’s long-established one-shop monopoly. This, as you’d suspect, has been terrible for Woody.

Forrest is not entirely full of hard working capable souls – for example, consider Vinnie the thief. Vinnie, like Woody, is descended from an ancient line of Forrest inhabitants. Vinnie, like Woody, pursues the same occupation as his father and his father’s father. But Vinnie, unlike Woody, isn’t exactly a clone of his ancestors.

Vinnie’s father was a notorious scoundrel. An aggressive thief and burglar, he was nevertheless as dimwitted as he was ruthlessness. It doesn’t take a genius to know that if you continue to steal from the same store over and over that there might eventually be nothing left to steal. This concept seemed totally lost on Vinnie’s father and as a result he almost caused Woody’s father to close the only store in town.

But, as suggested, Vinnie was not cut out of the same aggressive yet witless stock as his father. Indeed, Vinnie is more bargainer than terrorist -- a theme established early in his life. When Vinnie’s father began to push him into the family business, his father told him: “Go into Woody’s store, show him who you are, break a few things then take what you want and stroll out like you own the place. That’s how it works for guys like us. That’s how it has always worked.”

Young Vinnie tried. He walked into Woody’s store and looked around. He picked up a few items that looked breakable and considered tossing them to the ground. But, soon he became aware of Woody’s suspicious gaze following him around and found himself placing the stock back on the shelf and adverting his eyes. Finally, Vinnie decided just to come clean.

“Do you know whose son I am?” Vinnie asked Woody naively.

“Of course.”

“Then how about you just give me a hundred bucks?”

Woody thought about this. A hundred dollars was actually quite a small price to pay compared to the usual cost in damage and theft. But, a hundred dollars for what exactly? A hundred dollars just to make some kid walk away? All things being equal, Woody would just assume he didn’t have Vinnie’s small-time extortions nor his father’s grand theft, but that really wasn’t one of the available options and therefore the proposed agreement would be the lesser of two evils.

“I’ll tell you what”, said Woody pulling out the cash, “I’ll give you one hundred dollars a week for doing absolutely nothing as long as you don’t make the same deal with my cousin Trey across the street. This will be your territory, but the store across the street stays your father’s territory. Deal?”

“Deal.” Vinnie said, shaking Woody’s hand three times.

And with that simple verbal contract, an arrangement was made. Each week Vinnie would come in, shake Woody’s hand three times, and earn a hundred dollars.

Over time, their relationship became, if not exactly friendly, at least routine. Little by little they forgot about the initial circumstances of the arrangement and found themselves acting like civil gentlemen considering the issues of the day.

One day, a small force of bandits from a nearby town attempted to invade, seeking to steal supplies and animals. Obviously, both Woody and Vinnie were desperate to repel this invasion and during the crisis all past discord was forgotten. Not surprisingly, between the two of them, Vinnie was the better fighter owing to the weapons and viciousness inherited from his violent family. That’s not to say that Woody didn’t engage the enemy, but violence is clearly Vinnie's comparative advantage.

A few months later, a fire broke out. As before, both Vinnie and Woody had a mutual interest in stopping this mortal threat. While Vinnie pitched in to fight the fire, this time it was Woody – with his access to buckets and hoses – who played the comparatively larger role in extinguishing this mutual threat.

And so it went. As the relationship normalized, they found that their common needs were greater than their distrust and consequently they found more and more ways that it was profitable to depend on each other’s specializations. Vinnie became not only the defender of the neighborhood but also the store’s out-of-town sales representative and Woody paid him a commission on his sales. Meanwhile, Woody’s freed resources meant that he was able to invest more in a nicer shop with more stock to the profitable benefit of both.

Generation after generation inherited the agreement and the benefit of specializing and working together turned out to be great. The paltry hundred dollars became not so much an extortion as just one part of a complex set of mutual exchanges of goods and services. In fact, Vinnie and Woody’s sons didn’t even know why they engaged in this weekly routine of thrice handshakes and an exchange of cash -- maybe it was some sort of ritual of friendship; maybe it had to do with some old debt now long since irrelevant; whatever, it seemed a quaint part of their past. To outsiders, it was hard to imagine the shop running without two employees, and most assumed that it had always been that way and always would.

Geometry of Biological Time, Chapt 2.


Co-tidal map from NASA via Wikicommons. The points of intersection are the "phase singularities" where the tidal phase is undefined.

Slowly making my way through this book. Chapter 2 is about phase singularities -- places where the phase of some oscillation is undefined. The coolest example is the earth's tides. The surface of the earth is a sphere ("S2" in topology speak) and the tides are defined by a phase (S1). So for each point on earth at any given moment there's a tidal phase. But S2->S1 mappings (with certain continuity assumptions) must contain phase singularities -- there must be places where you can't define the phase. Above is a map from NASA showing these places as the intersections of the co-tidal lines. You can think of the tides as sloshing around those points where the sea level doesn't change.

The chapter is mostly about biological versions of such phase singularities. Detailed examples are given from fruit fly circadian rhythms, but the technical details of the experiments were overwhelming so I didn't fully follow and decided, perhaps unwisely, to plod forward without complete understanding.

BSTQ - Bull Shit Tolerability Quotient

There are many traits that determine someone's performance in various social settings such as school, work, military, etc. A popular metric for correlation to "success" in such social system is the "Intelligence Quotient" which purports to measure elements of abstract intelligence. Another metric that has gained popularity is the "Emotional Intelligence Quotient" which purports to measure the ability to perceive and mange emotions in oneself and others. Both of these metrics claim a high correlation to success in aforementioned social institutions.

I submit that success in roles within said social systems -- student, factory worker, warrior, etc. -- requires a high tolerance of activities such as: implementing poorly articulated tasks, engaging in inane conversations, attending pointless engagements, and other time-wasting activities known informally as "Bull Shit" (BS). The ability to tolerate such BS is a very important trait that is not normally rigorously evaluated.

I propose a simple test to measure an individual's tolerance for BS: a list of increasingly inane questions and pointless tasks is given to the test taker. For example, the test might begin with questions like: "Fill in the blank: Apples are __ed" and end with stupendously pointless tasks such as "Sort these numbers from least to greatest" followed by several hundred ~20 digit numbers and then having the next task say: "Now randomize those same numbers". The Bull Shit Tolerability Quotient (BSTQ) would just ignore the given answers and simply count the number of questions that test taker was willing to consider before handing the test back in frustration and declaring: "This Bull Shit!"

If a formal BSTQ test is not available, most standardized academic tests can be used as a reasonable substitute. However, the dynamic range of such generic academic tests to measure BSTQ is low. In other words, only extreme low-scorers of a proper BSTQ test will be measurable via the number of unanswered questions on a standard academic test used as a BSTQ surrogate. Extreme caution must be used when interpreting an academic test as a BSTQ analog -- the test giver may misinterpret the number of unanswered questions as the result of the test taker's low knowledge of the test's subject matter instead of as a spectacularly low BSTQ score.

BSTQ tests can easily be made age independent. For pre-verbal children the test would involve increasingly inane tasks such as matching sets of colored blocks to colored holes and so forth. The test would simply measure how many of these tasks the pre-verbal child could engage in before he or she became irritated or upset with the examiner.

Like the IQ and EIQ I suspect that the BSTQ will be correlated to the degree of success within many social endeavors, in particular: school; however, I also suspect that there is a substantial fraction of the population that has an inverse correlation between their IQ and their BSTQ scores. Of these, of particular interest are those with high IQ with low BSTQ. I would not be surprised if the population of people rated by their co-workers as "indispensable" is significantly enriched for individuals with a high IQ / low BSTQ score. Finally, I submit that these individuals are severely under-served by the educational system which demands -- indeed glorifies -- extremely high BSTQ, especially among those with high IQ.

Adding a BSTQ evaluation to pre-academic children might suggest that the student would excel in a non-traditional educational environment where the student is allowed to select their own agendas and tasks. A very low BSTQ coupled with a very high IQ would seem to almost guarantee rebellion if a traditional educational approach is applied. Identifying individuals with exceptionally high IQ scores and exceptionally low BSTQ scores may be a valuable tool to prevent the mis-classification of such students as "trouble makers" and instead correctly classify them as "potential indispensable iconoclasts".

Belief in torture's efficacy = Belief in witchcraft



This piece on Slate about the history of witch hysteria demonstrates to me the absolute absurdity of torture. Anyone who thinks that torture techniques such as waterboarding are effective tools of interrogation must also believe in witches. Why? Because throughout history (and into the present day) people have confessed to being witches under torture. Therefore, if you believe that torture works to "extract the truth" then all those people who confessed must really have been witches!

This demonstrates the insidious evil nature of torture. Not only can the torturer come to a false conclusion -- the one they want -- but even the tortured can come to hold the same false ideas. In other words, torture isn't merely morally reprehensible, but it doesn't even work!

Indeed, suppose you were "the Devil" and your goal was to explicitly foil legitimate interrogations because, as the devil, you had a sick desire to ensure chaos reigns throughout the world. As such, you couldn't come up with a "better" interrogation technique than torture. The questioner ends up reinforcing the ideas they started with and thereby ignores possibly valid alternative leads and the suspect may end up believing the planted ideas thereby reinforcing the incorrect assumptions of the torturer. If it weren't horrific, it would be the plot of a goofball comedy where two characters engage in a circular conversation convincing themselves of something absurd like up is down or love is hate. A "real" malevolent Devil would watch humans engaged in such cruel pointless floundering and be amused to no end. Will we stupid humans ever stop entertaining "the Devil" by engaging in this ghastly charade given the obvious pointlessness and immorality of it? Signs are not hopeful.

Shopping in the Science Supermarket



"Can you tell me where the mustard is?", I asked the nerdy looking storekeeper.

"It's next to the mayonnaise."

"Um okay....... But where is the mayonnaise?", I replied peevishly.

"Near both the ketchup and the soup."

"Again, this isn't really helping me. Maybe some sort of landmark independent of the foodstuffs themselves would be helpful?"

"Sorry."

"I mean, really? All you can give me is the location of everything in terms of other things! I want mustard and I'm standing next to radishes what am I suppose to do?!"

"Radishes are near the soup!"

"And?"

"Soups..." he directed me like I the slow child I was, "... are... near... the... mayonnaise."

And so I headed towards the soup. Turns out something called "onions" are also near the soup and the smell of these caught my attention: so pungent yet sweet. I peeled one back to see what was inside and what I found was... another onion! Onions are made of onions?! How can that be? So I tore open the onion and found onions all the way down.

That was 30 years ago. Someone just asked me where the mustard is. I don't know, I never did find it but, I told him. "the mayonnaise is near the bread."

Tree logic



The pecan in front of my house is slow. I think it might be, you know, one of the thicker trunks in the forest. The tree in the back yard tells me that it's time to blossom, flower, leaf out, spread its tree-semen with abandon. I say delicately to the front tree, "Look, I don't want to criticize, but, you know, the tree in the back..."

The front tree is having none of this; and, frankly, it resents being judged. "Look, just stop right there monkey," it says to me "I don't need to hear your thoughts on this. I was planted here 100 years ago. I didn't ask to be put here. I'm doing the best I can. I'm from Illinois, I know about snow. You ever had snow on your new leaves? No, you haven't because you're an ape. Trust me, you don't want to get caught out in that. I'm not going to get caught out in that."

"But in the 100 years you've been here has it ever snowed in April?" I queried cautiously.

"I got my ways. I've never been caught out in the snow."

"But it doesn't snow here in spring."

"And I've never been caught out in it."

"But if you don't get a move on, you're going to lose your chance to pollinate the other trees. I mean, don't you care about your legacy?"

"I'm not interested in having children that are so dumb as to leaf out too early and get caught in the snow. I don't want to breed with those premature blossomers, like your friend back there -- that's reckless risk taking. Rather not have children than have stupid children," the tree sulked.

"But it doesn't snow here in April." I repeated.

"And I've never been caught out in it."

Rugs!



The first of a few new rugs has arrived. Thanks to Amberlee for all the help in finding these. I especially like the runner in the entrance.
