Here is a good blog post showing one great feature of the blogosphere (that term seems to have fallen out of use hasn’t it): interaction. It also shows that you have to think critically. You can’t just accept what you read (you never can, but that is even more true with blogs than it is with newspapers that at least have some standards normally). I tend to agree with this posts look at the data, though I have not examined the issue closely.
Bad Math, Bad Statistics: Trying to get a blogger to admit a mistake
1981: 229465714 * 8476.0 = 1.944 trillion
1992: 255029699 * 14847.0 = 3.786 trillion (94% gain)
2005: 292892127 * 25036.0 = 7.332 trillion (93.6% gain)
Er, doesn’t look like a lag to me. In fact, it looks like it’s doubling every 12-13 years just as much as GDP is. I also looked up total income statistics for the US, and found the following figures (source). (Note these figures are different. More on that later.)
1981: $2,580,600,000 (2.58 / 3.1 = 83% of GDP)
1992: $5,349,384,000 (more than double!) (5.34 / 6.2 = 86% of GDP)
2005: $10,252,973,000 (another double!) (10.25 / 12.4 = 82% of GDP)
Anyway it is a much more interesting argument than I would hear when I listened to TV “pundits” years ago spout meaningless talking points at each other. Granted they argument is not going to be studied as a wonderful example of how we should debate. Still it is much above what passes for debate from our politicians (yes this is more a sad commentary on how failed our politicians are than a statement of how marvelous the argument on the GDP issue is between the two bloggers).
Here is a math question for you, what has a bigger impact moving from 15 to 18 mpg or 50 to 100 mpg?
