Of course the political news is all ablaze with the ramblings of Glen Beck’s rally in Washington. I was keen to hear the attendance numbers and ensuing vitriol that would be spat from all sides on said numbers. In a mud put like this how does one separate fact from fiction?
Ah science – even the sketchy, fuzzy science of crowd counting delivers better numbers than the biased squint and pull a number out of your ass routine that we’ve seen come from all sides of the media.
Steve Doig does this kind of science. You can read about his latest efforts on Glen Beck’s rally:
My estimate is that about 80,000 people were at the rally. Ryan Shuler, an Airphotoslive image analyst, used the same images and a different grid-density method to produce an estimate of 87,000. Considering the error margins around our separately-calculated estimates, they are statistically identical.
Of course he’s taken all kinds of heat for publishing this from the same right-wing groups that lauded his numbers on the Obama inauguration.
Do numbers really mean anything? Not always. In fact, often it becomes a crutch, a logical fallacy - argumentum ad populum, that because a lot/too little people were there an idea is good/bad. How many news stories will fill the airwaves balanced on this exact crutch rather than addressing the issues that were presented? Too many.
I fully expect one of the few, if only place that will actually dissect the messages presented at the rally will be the Daily Show. Then again, throughout all of man’s history comedy and satire has always delivered the truth.
