Irrational exuberance is a term used to describe behavior that is characterized by excessive, irrational, and often uncontrollable enthusiasm or passion. It is a psychological state in which one’s emotions and judgments are driven by intense, irrational feelings of excitement or admiration for a particular object, person, or idea.

Symptoms:

• Unreasonable enthusiasm: Excessively positive emotions and reactions to an object, person, or idea that are not proportionate to its actual merit.
• Lack of rationality: Difficulty controlling emotions and judgments based on logic, reason, or evidence.
• Impaired judgment: Inability to make sound judgments due to emotional bias and irrational exuberance.
• Disproportionate investment: Dedicating an overly large amount of time, resources, or energy to an object or idea.
• Believing in impossible or excessive outcomes: Holding unrealistic expectations or beliefs about the potential outcomes of a situation.
• High-risk behavior: Engaging in risky or dangerous behavior without considering the potential consequences.
• Emotional volatility: Fluctuations in mood and emotional states that are influenced by external factors or the object of passion.

Causes:

• Emotional dysregulation: Difficulty controlling emotions, which can lead to irrational exuberance.
• Histrionic personality disorder: A personality disorder characterized by excessive emotionality, exhibitionism, and lack of self-control.
• Mania: A mental condition characterized by uncontrolled impulsive behavior, often related to substance abuse or gambling.
• Certain neurochemical imbalances: Imbalances in neurochemicals such as dopamine and serotonin can contribute to irrational exuberance.
• Cultural factors: Certain cultures may encourage emotional expressiveness and exuberance.
