Answer
Rational thinking is a cornerstone of Rational Emotive Behavior Therapy (REBT). REBT posits that irrational beliefs and thoughts lead to negative emotions and behaviors. By challenging and disputing these irrational beliefs, individuals can develop more rational thinking patterns, which in turn promote emotional well-being and adaptive behaviors. REBT emphasizes the importance of identifying and replacing irrational thoughts with rational ones, thereby fostering a more positive and realistic outlook on life.
