Irrational Thinking is a pattern of thinking in which conclusions, beliefs, or interpretations are not adequately supported by available evidence or sound reasoning. It may feel completely convincing to the person experiencing it because emotions, assumptions, biases, or previous experiences may strongly influence how information is interpreted.
Common forms of irrational thinking
Pattern Example
All-or-nothing thinking “If I fail once, I’m a complete failure.”
Catastrophizing “If this goes wrong, my life will be ruined.”
Mind reading “I know they’re judging me.”
Fortune telling “I already know this will end badly.”
Emotional reasoning “I feel unsafe, therefore I must be in danger.”
Overgeneralization “Everyone eventually betrays you.”
Personalization “They seem unhappy, so I must have done something wrong.”
Confirmation bias Looking mainly for evidence that supports what you already belive Magical thinking Believing that thoughts, rituals, or unrelated events directly cause outcomes without evidence of a causal connection.
False certainty Treating an assumption as an established fact.
Irrational thinking may not be necessarily “crazy”
Everyone engages in irrational thinking sometimes. Stress, anxiety, fear, anger, grief, trauma, sleep deprivation, and strong emotional states may make reasoning less flexible.
A useful distinction may be:
Thought…Interpretation…Belief…Action
For example:
“My friend hasn’t responded.”
“Something must be wrong.”
“They’re angry with me.”
“I should confront them.”
The initial fact is observable. The subsequent conclusions may or may not be accurate.
Rational thinking may ask different questions
Instead of asking:
“How do I feel about this?”
Rational thinking adds:
What do I actually know?
What am I assuming?
What evidence supports my interpretation?
What evidence contradicts it?
Are there alternative explanations?
Am I confusing possibility with probability?
What would change my mind?
Am I reacting to the present situation or to something from my past?
An important clinical distinction
Irrational thinking exists on a continuum. Ordinary cognitive distortions are different from severely impaired reality testing.
For example:
Cognitive distortion: “My boss didn’t smile at me, so maybe she’s upset with me.”
versus
Fixed false belief: “My boss is secretly transmitting messages into my mind through the office lights.”
The second example raises a substantially different clinical question because the belief involves reality testing, evidence evaluation, and potentially delusional conviction.
A useful principle is:
A thought may feel true without being factually true.
That distinction between subjective certainty and objective evidence is central to rational thinking, critical thinking, and psychological reality testing.
