Final answer:
REBT suggests that blame is the core of most emotional disturbances, stemming from rigid and irrational beliefs about adversities.
Step-by-step explanation:
According to Rational Emotive Behavior Therapy (REBT), developed by Albert Ellis, the core of most emotional disturbances is blame. REBT posits that when individuals face adversities, it is not the events themselves that cause emotional disturbances, but rather the rigid and extreme beliefs that they hold about these events. Ellis identified three major musts or irrational beliefs that can lead to self-defeating emotions and behavior: “I must do well and be loved and approved by others,” “Others must treat me fairly and justly,” and “The conditions under which I live must be comfortable, enjoyable, and hassle-free.” When these beliefs are not met, individuals tend to blame themselves, others, or the world, leading to emotional turmoil.
