Today’s release is the latest in our series of audio versions of our articles.

In this one — How much does a vote matter? — I investigate the two key things that determine the impact of your vote:

• The chances of your vote changing an election’s outcome
• How much better some candidates are for the world as a whole, compared to others

I then discuss what I think are the best arguments against voting in important elections:

• If an election is competitive, that means other people disagree about which option is better, and you’re at some risk of voting for the worse candidate by mistake.
• While voting itself doesn’t take long, knowing enough to accurately pick which candidate is better for the world actually does take substantial effort — effort that could be better allocated elsewhere.

Finally, I look into the impact of donating to campaigns or working to ‘get out the vote’, which can be effective ways to generate additional votes for your preferred candidate.
