Blame
In CBT, blame — whether directed outward at others or inward at yourself — is understood as a thinking pattern that tends to block problem-solving and emotional resolution.
When you externalise blame, you place full responsibility for your distress onto other people or circumstances, which can feel temporarily satisfying but leaves you stuck, because it positions you as a passive victim with no agency to change anything.
When you internalise blame, you hold yourself wholly responsible for everything that goes wrong, often in harsh, globalising ways ("I always ruin everything"), which fuels depression, shame, and low self-worth.
Either direction, blame tends to be black-and-white thinking — assigning 100% responsibility to one source rather than acknowledging the messier, more accurate reality that most situations involve multiple contributing factors.
CBT doesn't ask you to abandon accountability — it draws an important distinction between responsibility and blame. Responsibility is clear-eyed and forward-facing: it asks "what is my part in this, and what can I do differently?" Blame is backward-facing and emotionally charged: it's about punishment, fault, and verdict.
A common CBT technique here is the responsibility pie, where you map out all the factors that contributed to a difficult outcome and assign rough percentages to each — which almost always reveals that your share of responsibility is smaller than the blame you've been carrying. The goal is to hold yourself and others accountably without the cruelty that blame tends to carry with it.
