The "presenting half of a story and drawing stark conclusions from it" fallacy. I suppose it falls under Straw Man?
Right now there's an attack ad against a politician in my state: "When so-and-so came into office, we had a balanced budget. Then so-and-so spent billions in taxpayer money and left the man who followed him to dig us out of a billion-dollar shortfall. The fact is so-and-so was a major disappointment."
I don't follow politics at all. I was never on a debate team. I'm not even a college graduate.
So how is it that an uneducated wretch like myself can point out all of the following?
1. Does not say what the money was spent on. Going over budget once or twice to substantially improve education or health care for the next thirty years would be of benefit in the long term. Implies spending money is always wrong and the short term effect is always more important.
2. Does not indicate factors outside of human control, e.g. natural disasters which would have required relief spending. In fact no disaster is necessary: a few years ago we had a mild winter followed by a particularly rainy spring. It wreaked havoc on the roads here due to constant freeze-thaw and excess runoff. We spent huge money so our roads wouldn't look like they'd been carpet-bombed. The ad implies incompetence or fault where none may exist. Nobody can be blamed for hurricanes, not even politicians (though I'm sure people have tried). If a disaster had occurred, and relief was not forthcoming, you can bet the ad would attack so-and-so for failing to provide relief, instead. Binary insult.
3. Does not indicate possible incompetence or delay tactics on the part of so-and-so's predecessors. If the guy before him set in motion a house-of-cards policy which looked great for six years, but caused disastrous overruns when it collapsed in year seven, would that guy get the blame? No. So-and-so gets the blame, because so-and-so was in office when the house of cards came down. Again, implies incompetence or fault where none may exist.
3. Assumes a balanced government budget is always attainable. Federal budgets are more than 10,000 pages long. State budgets must be of similar complexity. This presents extreme difficulty to anyone trying to decide what is least necessary. Even when the choice is simple, it is seldom easy. If you can either A) cut aid to the elderly, or B) cut education, how do you choose? There is simply never enough money to go around. There is no single right answer as to what to spend or how to spend it. Balanced budgets are good but, when people suffer for every cut, it's hard to make the choice. (inb4 Balance It By Taxing The Wealthy. It's a pretty good bet that's not going to happen.)
4. Forms opinion based on extremely limited information. Presents this opinion as ironclad fact. This wouldn't be any more insulting or ridiculous if they told us Santa Claus was real.
It doesn't bother me so much that this is done. The sun rises, rivers flow, politicians lie and spin. It's more or less their job. [/cynic]
What bothers me is it must work. If this ignorant, one-sided crap didn't work, we wouldn't get so much of it.
