Quick answer: Automatic negative thoughts (often called ANTs) are quick, unplanned thoughts that pop into your mind in response to a situation and push your mood down, such as "I always mess this up" or "They think I'm boring". In cognitive behavioural therapy (CBT), they're the thoughts you learn to notice, write down and check against the evidence. You can't stop them appearing, but you can get much better at catching them and deciding how much to believe them.
Key takeaways
Automatic thoughts arrive on their own, in a second or two, and often feel like facts rather than opinions.
They matter because they shape how you feel and what you do next, often before you notice them.
Everyone has them. The aim isn't to get rid of them, but to spot them and weigh them up.
A simple routine helps: catch the thought, check it against the evidence, then change it to something more balanced.
Writing thoughts down close to the moment makes them far easier to examine later, on your own or with a therapist.
What are automatic negative thoughts?
An automatic thought is one that pops into your head without you choosing it. The Centre for Addiction and Mental Health (CAMH) describes how, in CBT, these thoughts shape the emotion you feel in a situation, and how CBT focuses on the negative automatic thoughts linked to strong low or anxious moods (CAMH: Cognitive-behavioural therapy information guide).
They're called "automatic" because they're fast and habitual. You don't sit down and decide to think "I'm going to fail this". It just arrives, and a moment later you feel tense or flat. Because the thought is so quick, it's usually the feeling you notice first.
The term comes from Aaron Beck's cognitive model of depression, which suggests that how we interpret events matters more than the events themselves. A review in the Indian Journal of Psychiatry summarises Beck's view that negative automatic thoughts both trigger and deepen low mood (Gautam et al., 2020).
What do automatic negative thoughts look like? 12 examples
Automatic thoughts are usually short and personal. Here are common examples, grouped by the kind of situation they show up in:
Situation | Automatic negative thought | Feeling it often brings |
A friend doesn't reply | "They're annoyed with me." | Anxious, hurt |
Making a small mistake at work | "I never get anything right." | Ashamed, low |
Before a meeting | "I'll say something stupid." | Nervous |
Looking in the mirror | "I look awful." | Low, self-conscious |
A plan changes | "This is going to be a disaster." | Panicky |
Someone else gets praised | "I'm not as good as everyone else." | Envious, flat |
Feeling tired | "I'm so lazy." | Guilty |
A partner seems quiet | "I've done something wrong." | Worried |
Starting a new task | "There's no point, I'll give up anyway." | Hopeless |
A social event | "Nobody will want to talk to me." | Lonely, anxious |
Getting feedback | "They think I'm useless." | Hurt, defensive |
Late at night | "Everything is going wrong." | Overwhelmed |
None of these thoughts is unusual. What matters is how often they show up, how strongly you believe them, and what they lead you to do.
Why do automatic negative thoughts happen?
Our brains are built to make fast judgements, especially about possible threats or rejection. That speed is useful, but it means first thoughts are often rough guesses rather than careful conclusions. When you're stressed, tired, low or anxious, those guesses tend to lean negative.
Automatic thoughts also follow habits. If you've often told yourself "I'm not good enough", that thought becomes easier to reach for. This is why the same few thoughts can turn up again and again in different situations, and why tracking them over time can reveal a pattern. Our guide to spotting patterns in your thinking explains how.
Night-time is a common trigger, because there are fewer distractions. If that's when your thoughts get loudest, see why you might overthink at night.
What's the difference between automatic negative thoughts and cognitive distortions?
They're closely linked, but not the same thing:
An automatic negative thought is the specific thought you had: "My boss hates my work."
A cognitive distortion is the type of thinking error behind it, such as mind reading (assuming you know what someone thinks) or catastrophising (expecting the worst).
The Canadian Mental Health Association in British Columbia calls these patterns "thinking traps", and describes them as automatic thoughts and assumptions that distort how you see a situation (CMHA BC: Challenge thinking traps). Naming the trap can make a thought easier to question. Our list of 10 common cognitive distortions covers the main types with examples.
How do I catch automatic negative thoughts?
Because they're fast, the trick is to use your feelings as a signal. When you notice a sudden change in mood, pause and ask: "What just went through my mind?"
Notice the shift. A drop in mood, a knot in your stomach or a sudden urge to avoid something is often the first clue.
Ask what you were thinking. Try to put the thought into words, exactly as it sounded in your head.
Write it down quickly. A few words in a notes app or a voice note is enough. Detail fades fast, so capture it close to the moment.
Rate how much you believe it. A rough 0 to 100% helps you see whether it shifts later.
Note the situation and feeling. Where were you, what happened, and how did you feel?
Our guide to tracking negative thoughts in the moment has more ideas for capturing thoughts on busy or hard days.
How do I challenge automatic negative thoughts?
The NHS suggests a simple three-step approach: catch the thought, check it, then change it (NHS Every Mind Matters: Reframing unhelpful thoughts). When you check a thought, useful questions include:
Is there good evidence for this thought? Is there any evidence against it?
What would I say to a friend who had this thought?
Am I falling into a thinking trap, such as expecting the worst or seeing things as all or nothing?
Is there another way of looking at this?
What's the most likely outcome, rather than the worst one?
Then try writing a more balanced thought. It doesn't need to be positive, just fairer. The NHS notes that this can feel hard at first and gets easier with practice, and that sometimes a thought can't be reframed, which is okay.
For a fuller, structured version, a thought record walks you through the situation, feelings, evidence and a balanced thought. The NHS calls the thought record a common CBT exercise (NHS Every Mind Matters: Thought record), and our step-by-step thought record guide has a worked example.
Worked example: catching and checking one thought
Here's how this can look in practice. This is an illustration, not a real person.
Step | What Priya wrote |
Situation | Sent a message to the group chat. Nobody replied for two hours. |
Feeling | Anxious, a bit embarrassed (70%) |
Automatic thought | "They find me annoying. I shouldn't have said anything." (Belief: 80%) |
Thinking trap | Mind reading |
Evidence for | One friend replied with a short message last week. |
Evidence against | It's a weekday afternoon and most of them are at work. Two of them messaged me yesterday. |
Balanced thought | "They're probably busy. A slow reply doesn't mean they're annoyed." (Belief: 65%) |
Feeling now | Calmer, still a little uneasy (35%) |
The thought didn't disappear, and it didn't need to. Priya believed it less and felt less anxious, which made it easier to get on with her afternoon.
Can you stop automatic negative thoughts completely?
Probably not, and that's not the goal. Automatic thoughts are a normal part of how minds work. What CBT aims to change is your relationship with them: noticing them sooner, believing them less automatically, and choosing how to respond.
If these thoughts are frequent, very distressing, or affecting your sleep, work, relationships or daily life, it's worth talking to your GP, family doctor or a therapist. CBT is a well-established talking therapy, and you can read more in our guide to what CBT is.
How MindTrace helps
MindTrace is a CBT-inspired thought tracker for iOS and Android. When an automatic thought shows up, you can capture it in a few seconds by text or voice, so you don't have to remember it later.

Frequently asked questions
What does ANTs stand for in CBT?
ANTs stands for automatic negative thoughts. It's an informal name for the quick, unhelpful thoughts that pop up in response to everyday situations and affect how you feel.
What is an example of an automatic negative thought?
Common examples include "I always mess things up", "They don't like me", "I'm going to fail" and "This is going to be a disaster". They're usually short, personal and feel true in the moment.
Are automatic negative thoughts the same as intrusive thoughts?
Not quite. Automatic negative thoughts are usually judgements about yourself, other people or the future that feel believable. Intrusive thoughts are unwanted thoughts or images that feel out of character and distressing. If intrusive thoughts are troubling you, talk to a GP, family doctor or therapist.
How long does it take to change automatic negative thoughts?
It varies. Many people find it easier to notice their thoughts within a few weeks of regular practice, but changing long-standing habits of thinking takes longer. Practising between sessions is a normal part of CBT.
Should I write down my automatic negative thoughts?
Yes, if you can. Writing a thought down, with the situation and how you felt, makes it easier to look at it calmly later and to spot patterns. A few words or a quick voice note is enough.
MindTrace is not a crisis service and doesn't replace professional care. If you're in crisis or worried about your safety, call or text 988 in Canada or the US, call 999 or Samaritans on 116 123 in the UK, or contact your local emergency services.
