“Delulu” Thinking Is More Common Than You Think

Reading Time: 3 minutes

Delusional thinking, colloquially referred to as “delulu thinking”, is a phenomenon that has fascinated psychologists and the general public alike. This term, a blend of “delusional” and “thinking,” is often used to describe a mindset where individuals hold firmly to beliefs despite clear evidence to the contrary. These beliefs can range from the seemingly benign – like the conviction that one is destined to marry a celebrity – to more dangerous and harmful convictions.

The nature of delusional thinking

Delusional thinking is not a modern phenomenon. Throughout history, humans have held steadfastly to beliefs that defy logic and reason. What differentiates delusional thinking from mere wishful thinking or optimism is the intensity and rigidity of the belief. Resistance to contrary evidence is a common trait of delusions. This means that no matter how much proof is provided to counter the delusional belief, the individual clings to it as if it were an undeniable fact.

Types of delusional thinking

Delusional thinking can manifest in various forms, often categorised based on the nature of the belief. Here are some common types:

  • Grandiose delusions. Individuals believe they have exceptional abilities, wealth, or fame. They may think they have a special relationship with a prominent person or deity.
  • Persecutory delusions. These involve the belief that one is being targeted, harassed, or persecuted. This can include thoughts of being spied on, plotted against, or subjected to unfair treatment.
  • Erotomanic delusions. The belief that someone, often of higher status, is in love with the individual. This can lead to obsessive behaviours and unwelcome advances towards the perceived admirer.
  • Somatic delusions. These involve beliefs about the body, such as having a disease or physical defect, despite medical evidence to the contrary.
  • Mixed delusions. A combination of various delusional themes without a dominant one.

Causes of delusional thinking

The exact cause of delusional thinking is complex and multifaceted. It is often a combination of genetic, neurological, psychological, and environmental factors. Here are some key contributors:

  • Genetics. A family history of mental health disorders can increase the risk of developing delusional thinking. Certain genes may predispose individuals to conditions like schizophrenia, which often includes delusions as a symptom.
  • Neurological factors. Brain abnormalities, such as imbalances in neurotransmitters like dopamine, can contribute to delusional thinking. Research has shown that areas of the brain responsible for perception and reasoning may function differently in those with delusional disorders.
  • Psychological factors. High levels of stress, trauma, and significant life changes can trigger delusional thinking. Psychological conditions such as schizophrenia, bipolar disorder, and severe depression often include delusions as a symptom.
  • Environmental factors. Social isolation, substance abuse, and certain cultural or societal influences can also play a role in the development of delusional beliefs.

The impact of delusional thinking

Delusional thinking can have profound effects on an individual’s life, impacting relationships, employment, and overall well-being. Here are some of the ways it can manifest:

  • Social isolation. People with delusional thinking often withdraw from social interactions, either because they feel misunderstood or because their beliefs lead to conflict with others.
  • Strained relationships. Delusional beliefs can strain relationships with family and friends. For example, someone with persecutory delusions might accuse loved ones of conspiring against them.
  • Employment challenges. Delusions can interfere with job performance and workplace relationships. Grandiose delusions, for example, might lead someone to overestimate their abilities and make poor decisions at work.
  • Legal and financial troubles. In some cases, delusional thinking can lead to actions that have legal or financial consequences. This is often seen in individuals with grandiose or persecutory delusions.

Treatment and management

Treating delusional thinking requires a comprehensive approach that addresses both the psychological and biological aspects of the condition. Here are some common strategies:

  • Medication. Antipsychotic medications are often prescribed to help manage symptoms of delusional thinking. These medications can help regulate neurotransmitter levels in the brain.
  • Therapy. Cognitive-behavioural therapy (CBT) is a common therapeutic approach for treating delusions. CBT helps individuals challenge and reframe their irrational beliefs.
  • Support groups. Joining support groups can provide individuals with a sense of community and understanding. It can also be beneficial for families and friends of those experiencing delusions.
  • Education and awareness. Educating individuals and their loved ones about delusional thinking can help them better understand and manage the condition.
  • Lifestyle changes. Encouraging healthy lifestyle choices, such as regular exercise, a balanced diet, and avoiding substances that can exacerbate symptoms, is crucial.


Delusional thinking is a complex and often misunderstood phenomenon. While it can be challenging to deal with, understanding its nature, causes, and treatment options can help those affected manage their symptoms and improve their quality of life. By fostering empathy, education, and support, we can create a more compassionate and effective approach to addressing delusional thinking.
