I developed this theory with colleagues starting in the 1980s, and it became the scientific foundation for ACT. I want to explain it plainly, because it answers a question most people have never thought to ask: why does language create suffering? Relational Frame Theory is a scientific account of how human language and thinking work. The core finding is that humans, uniquely among animals, learn to relate anything to anything else in an almost infinite number of ways: this is like that, this is better than that, this causes that, this is the opposite of that. This ability is what gives us science, art, and civilization. It also means we can never fully escape painful experiences by changing our environment, because any situation, any word, any sunset can trigger an entire network of connected meanings that brings pain back. A dog can learn to avoid a hot stove by touching it once. A human being who has been hurt by someone named Michael can feel anxious meeting a new Michael who has done nothing wrong, simply because the name carries the relational network forward. That's RFT in action.
