Fear of Commitment in 27 Pages

The City of Richardson's Statement of Goals has always been a grab bag. Part vision and mission statement, part job description for city government, part wish list, part laundry list, it's a jumble of goals, priorities and action items. Its length is indicative of its problems. This year, after several multiple hour sessions, the City Council managed to whittle it down from 28 pages to, let's count 'em, 1, 2, 3, ..., 27 pages.

After the jump, some random examples of what's wrong with the current draft of the City of Richardson's Statement of Goals.

Counting the Holes, Not the Trees

How do you count 50,000 trees? How do you count 3,000,000? Recently, I blogged about Richardson's "Tree the Town" program (goal: plant 50,000 trees) and North Texas's "Tree North Texas" program (goal: plant 3,000,000 trees) and pondered the challenge of counting all those trees.

Since then, I've learned a thing or two from readers (wonderful readers!) that turns my thinking completely upside down. I experienced an "ah ha!" moment. You know, when the light bulb clicks on over your head (the new cool squiggly kind, not the old Easy-Bake Oven heat source kind). I was thinking about the problem of counting trees in the exact opposite way I should have been. The experience reminded me of a chapter in the history of science:

"Around 1752, Benjamin Franklin developed his theory on the flow of electricity. Franklin believed that electricity flows like a fluid, and this fluid flows from areas of positive charge to areas of negative charge. It would be over 100 years before it was understood that current flow was actually the movement of charged particles.

"By the time science understood that electric current was the movement of negatively charged electrons, it was too late to change the standards, the textbooks, the schematic diagrams, and the generally accepted theory. The direction of current flow was set as opposite to the actual flow of the charge carriers, which we now know flow from areas of negative charge to areas of positive charge."

Today, it's best to think of electric current not as a flow of electrons in one direction, but as a flow of "holes" left behind as electrons move in the opposite direction.

After the jump, why Ben Franklin's mistake is like the challenge of counting trees.

Budget Apples, Oranges and Cherry-Picking

Yesterday, I cited Texas jobs' data as the perfect example of how data can be cherry-picked in different ways to tell two completely different stories. Do the jobs' data make Rick Perry's case for a Texas economic miracle? Or do they make his critics' case for a Texas economic myth? The answer to both questions is yes.

Last week, I explored the City of Richardson's proposed budget. I reconstructed historical data from the last six of Richardson's budgets. I concluded that "the fact that Richardson's proposed 2011-2012 budget shows a very slight deficit is not a cause for concern."

Is this another case of cherry-picking data? After the jump, an analysis.

The Best of Times, The Worst of Times

"There are three kinds of lies: lies, damned lies, and statistics."
" 'Lies, damned lies, and statistics' is a phrase describing the persuasive power of numbers, particularly the use of statistics to bolster weak arguments, and the tendency of people to disparage statistics that do not support their positions. It is also sometimes colloquially used to doubt statistics used to prove an opponent's point. The term was popularised in the United States by Mark Twain (among others)."
-- Wikipedia
Never was that phrase more apt than in first days after Texas Gov. Rick Perry announced his run for the 2012 GOP nomination for President. Perry made his record of job creation in Texas a centerpiece of his campaign. Critics, including a Nobel Prize-winning economist, quickly pointed out weaknesses in Perry's claim (see here and here). My topic today isn't so much who is correct, as how this topic has provided the perfect illustration of the old saying about "lies, damned lies, and statistics."

After the jump, two charts.

Global Warming, Evolution and Team Eve

Jon Huntsman, the 2012 GOP candidate for President, tweeted, "To be clear. I believe in evolution and trust scientists on global warming. Call me crazy."

To which, Time's Joel Stein tweeted back, "I'll call you Not the GOP Nominee."

That exchange gives me the opportunity to round up news items on some of my favorite topics. After the jump, Global Warming, Evolution and Creationism, the conversation starters - and enders - that never let you down.
