REBT believes that irrational thinking is the core of psychological problems. REBT points out several specific irrational beliefs that people exhibit. These requirements include: harsh or mandatory-rigid beliefs that allow people to think in absolute terms such as “must” and “should”. For example, “I have to pass this test” or “I should always be loved by my important others.” The views expressed in these statements are often unrealistic. This dogmatic thinking can paralyze individuals and destroy them. For example, I hope to pass the test, but it may not pass. If an individual does not accept the possibility that he or she may fail, this can lead to delays and attempts to fail because they are worried about what will happen if they fail. Awful – personally, experience or situation is the worst thing that can happen. The horrific statements include words such as “terrible”, “terrible” and “terrible”. Literally, these statements give individuals nowhere to improve the situation and are therefore not constructive.
