Voting is not rational (usually.)

araneae

Today is the midterm elections in the United States, and I am not voting.

For the vast majority of elections, voting is irrational, because the individual's vote is proportionately very small. This means it cannot have an effect on the outcome.

There are, however, conditions which can lead to voting becoming rational, and these are:

The number of voters approaches zero.
The ratio of votes for candidates (in a majority wins, 2 person race) approaches .5
The difficulty of voting becomes vanishingly small.
Incentives are created to make the costs of not voting greater than the cost of voting (for instance, not voting is illegal in Australia, and incurs a fine.)

For me, as for nearly everyone, voting this year is irrational. 1 and 2 are nowhere close to true, and 3 is especially bad for me this year. I forgot to change my address on my voter's registration until yesterday and my polling location is both a) usually overpopulated and filled with long lines and b) farther than I care to go.

Only 3 and 4 are something that we can certainly do something about. The web-based absentee voter system that was tested this fall is a step in that directions, but its subsequent hacking was unsurprising. Is opening our system up to fraud a reasonable trade-off to get more people to vote? Should there be an option to use paper absentee-like ballots even if you are not absent? Should the U.S. go the Australia route?

The reason to discuss it is that one of the strengths of a rationalist website is (more) rational discussion of issues in which there is a high degree of irrationality (e.g- politics). To the extent people on such a site are more rational they are more likely then politicians or political debaters to get accurate answers to the problems on which there is public debate.

The risk here is in several dimensions. First, I expect the rational answer is often "I don't have enough information to have an informed opinion." Second, it seems easier to develop rationality on simple, painless issues before moving to complex, painful issues. Telling people about the dangers of identity in the abstract, letting that sink in, then having them find examples in their life is one thing; introducing them to the concept with something fundamental to their identity is another entirely. I haven't seen much talk about religion here- p... (read more)
