Tinkerbell effect
The Tinkerbell effect is a term describing things that are thought to exist only because people believe in them. The effect is named for Tinker Bell, the fairy in the play Peter Pan who is revived from near death by the belief of the audience.
Claimed cases include:
- private property[citation needed]
- the value of a nation's money in a fiat system[citation needed]
- the demand for gold outside its use in industrial applications[citation needed]
- civil society[citation needed]
- the rule of law[1]
Reverse Tinkerbell effect
The efficient-market hypothesis can be regarded as a case of reverse Tinkerbell effect, in that the market would stop being efficient if everyone acted like it already was efficient.[2]
An example of the Reverse Tinkerbell Effect is that of a vote in a democracy. The more people that believe their vote counts towards the outcome of an election, the less their votes count, as there is a greater population of voters, and thus each individual voter has a lower percentage of total votes.
Examples
Tinkerbell effect:
- (Fiat) money: Paper money is actually worth something only because people think it's worth something.
- Popularity: The more popular others think that someone else is, the more popular he or she actually becomes.
Reverse Tinkerbell effect:
- Car safety: The more people think that automobiles are safe, the less cautiously they will drive, creating the reverse effect.
- Value of votes: The more people believe that their vote is valuable, the higher the number of people that vote. This reduces the overall impact of any single vote.
