We need to stop using the term “conspiracy” alone. Instead a conspiracy probability should be associated with every such theory.
As a strawman, a conspiracy which requires 10K people or more to pull it off gets assigned 0.0, while a single person conspiracy is assigned 1.0.
So anytime someone tells you about a conspiracy theory, ask them to estimate the conspiracy factor.
Examples of high conspiracy factor theory’s would be sports with a single, extremely important player (a goalie) for example since only one person needs to be corrupted.
An example of a low conspiracy factor theory would be the Moon landing as 1000s of people would need to be corrupted.
