Popular delusions are ideas or cultural fads that become transiently popular in a given society. They are characterised by their rapid transmissibility and fickle nature. Historically, they start with a trigger (see Figure 1) then move rapidly into their hype phase, and cause frantic activity of crowds such as the South Sea Bubble (see Figure 2), Tulip Mania or Witch Mania. Today popular delusions have become ever more transmissible through the use of social media and the advertising industry. The Pessimist Archive tracks popular delusions overtime to remind us when we are in a fad, they may seem permanent but they are merely temporary blips.

Popular delusions can have significant impacts on society and individuals. They can lead to irrational behaviors, poor decision-making, and in some cases, can result in harm or injustice. Understanding and recognizing these delusions can help individuals and societies make more informed and rational decisions.

It's important to note that what may be considered a "delusion" can be subjective and may vary across different cultures and societies. What one group considers a delusion, another group may consider a deeply held belief or tradition. Therefore, the term should be used with caution and understanding of its potential cultural implications.
