Thinking trap

Should statements: what it is, with everyday examples

Updated 2 November 2026

Should statements
Rigid rules about how you or others must be.

“Should”, “must” and “ought to” turn a preference into a rule. When the rule is about you, breaking it brings guilt; when it's about other people, it brings frustration.

Everyday examples

  • About yourself

    “I should never make mistakes.”

  • At work

    “I must answer every email the same day.”

  • Others

    “He ought to know how I feel without me saying it.”

Questions to check the thought

From the Socratic questions in ThinkGO. Pick one or two; you don’t need all of them.

  1. What does believing this thought do for you? What might change if you saw it differently?
  2. If a friend had this thought, what would you tell them?
  3. What points to this thought being true? What points the other way?

A fairer alternative

The trap

“I should never make mistakes.”

A fairer thought

“I'd like to make fewer mistakes. Everyone makes some, and I can learn from mine.”
