Thomas Theorem

Also called Definition of the situation

If people define situations as real, those situations are real in their consequences.

The Thomases stated it in 1928, and Merton built the self-fulfilling prophecy directly on it. Sometimes wrongly attributed to Schelling.

In practice

  • A rumour that a school is closing empties its reception intake, and the falling roll becomes the reason to close it.
  • A market that believes a currency will be devalued sells it, and the selling is what forces the devaluation.
