This is nonsense. For instance, in the last approval voting election for the board of trustees at Dartmouth, there was an average of 1.8 approvals per ballot for four candidates. The average voter voted for almost half of the candidates. http://scorevoting.net/BulletBugaboo http://scorevoting.net/BulletBugaboo Approval voting is beloved by game theory experts specifically for its immense resistance to strategy. It was adopted by a 64% landslide majority in Fargo and a 68% landslide majority in St Louis.

Approval voting isn't resistant to strategy. Whether or not to bullet vote or not is a very complicated strategic decision that has huge effects.

  No voting system is resistant to _all_ strategies, but some strategies are worse than other strategies.

  Yes, approval voting is resistant to strategy. Here are Bayesian regret and VSE figures showing it performs excellently, generally better than IRV/RCV in all kinds of strategic scenarios. https://www.rangevoting.org/BayRegsFig https://www.rangevoting.org/BayRegsFig https://rpubs.com/Jameson-Quinn/VSE5key https://rpubs.com/Jameson-Quinn/VSE5key Here's a mathematical proof that, even in the worst case scenario where 100% of voters are maximally strategic, approval voting elects the Condorcet winner (candidate who beats every rival head-to-head). https://www.rangevoting.org/AppCW https://www.rangevoting.org/AppCW Moreover, in 422 of the 440 ranked choice voting elections since 2004, the winner was the candidate with the most first-place votes. So even if it was true that everyone would just bullet vote with approval voting, approval voting would still elect the same winner as RCV 96% of the time. At radically lower cost and complexity. https://clayshentrup.medium.com/bullet-voting-is-fine-52e6f22057a9 https://clayshentrup.medium.com/bullet-voting-is-fine-52e6f2...
