Voting is irrational, goes the economic saying.Â Because the amount of effort involved on your part is so much greater than the infinitesimalÂ input you provide into the process.
It stand to reason, therefore, that the fewer people who vote, the more valuable or meaningful your input is.
Which means that there’s a body of voters N at which it is no longer irrational to vote… with a small enough sample, your vote is very valuable.
By decreasing the number of people who vote, you increase the value of your own vote.Â It is, therefore, entirely rational to try to convince people that they should not vote, because of the benefit that brings to your own vote.
So, for example, a professor of economics who attempts to convince you that voting is irrational is, indirectly, attempting to increase the value of their own vote!
