The principle that underlies cognitive therapy is that a person’s emotions and behaviors are largely determined by their thoughts and interpretations of events, rather than by the events themselves.

Core idea in one line

  • How you think about a situation shapes how you feel and what you do far more than the situation itself.

What this means in practice

  • People do not simply react to events; they react to the meaning they give those events (their beliefs, assumptions, and automatic thoughts).
  • By identifying and changing distorted or unhelpful thoughts, people can reduce emotional distress and change problematic behaviors.

Classic cognitive therapy view

  • Cognitive therapy focuses on “automatic thoughts” and deeper beliefs (like “I’m worthless” or “The world is unsafe”) that color how someone interprets everyday experiences.
  • The therapist and client work together, in a structured, time-limited way, to test and revise these thoughts against real-life evidence.

Why this principle matters today

  • This principle explains why the same event can feel devastating to one person and manageable to another: their internal commentary is different.
  • It also underpins modern cognitive-behavioral therapy (CBT), one of the most researched and widely used therapies for conditions like depression and anxiety.

In short: the guiding principle of cognitive therapy is that changing maladaptive thinking can change how a person feels and behaves, because thoughts, feelings, and behaviors are tightly interconnected.
