Thinking errors happen regularly to many of us. These “errors” are faulty ways of thinking that can cause us to feel defeated and bring on unwanted emotional behaviors and feelings.  Being strong mentally can be challenging at times and requires you to manage the way you’re thinking, control your emotions and the way you’re feeling and act responsibly and adequately despite what is going on around you.  You may be the type of person who struggles in these areas and find this difficult, but more often than not, the overriding factor is the way we think. How you think, handle, and react to a situation is essential.

It’s easy for many people to get inside their heads and begin to overthink a situation. They may even anticipate an outcome before anything has even started. Sometimes that inner voice is hard to overcome, and it directs us in the wrong direction. It can cause problems with work, relationships, and other aspects of your life.

About 5 years ago, a health care professional shared with me these 10 common thinking errors and ways to challenge them. I reference these daily when I catch myself thinking a certain way. It’s not always easy to do, but it has helped me in many a situation. These are good for anyone, young and old!

10 Common Thinking Errors and How To Overcome Them


Black and White Thinking

Thinking in black and white is thinking that everything is either good or bad, there is no in-between. You’re either great, or you’re a loser. People are good and bad, and life is filled with either successes or losses. You do not see shades of gray. It is one way or the other. When you think in black and white, you can’t see any benefits from a loss or a failure.

Try to look for shades of grey. It’s important to avoid thinking about things in terms of extremes. Most things aren’t black and white. Usually, they are somewhere in-between.

Ask Yourself:

  • Is it so bad, or do I see things in black-and-white?
  • How else can I think about the situation?
  • Am I taking an extreme view?



Unreal ideal/unfair to compare

Making unfair comparisons between specific individuals and yourself. You compare yourself to people who have a particular advantage in some areas. Making unfair comparisons can leave you feeling inadequate. Looking at your neighbor who drives a sports car and thinking, “I should have that too,” isn’t helpful. Don’t measure your life against someone else’s, commit to focusing on you, and how you plan on achieving success. It also helps to be grateful for what you do have.

Ask Yourself:

  • Am I comparing myself with people who have a particular advantage?
  • Am I making fair comparisons?
  • What am I thankful for?




When you filter, you hone in on the negative aspects of your situation, and you ignore or dismiss all the positive aspects. You could have a day where 5 things went your way, but one didn’t, and this becomes “a bad day.” You didn’t have a bad day you just had one bump in the road.

You need to consider the whole picture. Aim for balance and notice the positives and the negatives.

Ask Yourself:

  • Am I looking at the negatives while ignoring the positives?
  • Is there a more balanced way to look at this?




When you personalize, you feel responsible for anything that goes wrong, even when it’s not your fault. People who personalize think that the world revolves around them. Every teenager has dealt with this at some point in their life while they wait to hear back from a boyfriend or girlfriend. “He/she doesn’t like me anymore, and they aren’t calling me back.”  There are a million reasons why the person may not be calling, don’t automatically jump to the negative.

Ask Yourself:

  • Am I really to blame?
  • What other explanations might there be for this situation?



Seeing the future

We are not fortune tellers, nor can we predict the future. We’ve all heard someone say, ” I don’t bother to go on diets because I only gain the weight back.” Thinking like this is only setting yourself up for failure. You’ve already put the negative thought in your head that dieting is a waste of time because you gain the weight back. Perhaps you gain the weight back because you don’t stick to your diet.

These “fortune tellers” are the doom and gloom people you run into daily. Don’t focus on the negatives that can happen but instead focus on the positive.

Ask Yourself:

  • What is the evidence? How do I know what other people are thinking?
  • Just because I assume something, does that mean I’m right?




When you catastrophize, you exaggerate the consequences when things go wrong, and you imagine that things are or will be disastrous. The catastrophizer believes things are always worse than they are. “I can’t believe I’m not married yet. I’m going to die alone”. Remember that your situation is only temporary and can always be changed.

For me, this is my most common thinking error. I think it’s because of all my years being in sales and dealing with rejection.

Ask Yourself:

  • What’s the worst thing that can happen and the best thing that can happen?
  • What’s most likely to happen?
  • Will this matter in five years?
  • Is there anything good about the situation?
  • Is there any way to fix the situation?

It can be easy to get swept up into catastrophizing a situation once your thoughts become negative.




When you overgeneralize, you exaggerate the frequency of negative things in your life, like mistakes, disapproval, and failures. “I’ll never close another sale again.”  Have you ever had an altercation with someone in a city you’re visiting and caught yourself saying, “Everyone in this city is rude.” That’s not necessarily the case, you’ve just run into one rude person.

Ask Yourself:

  • Am I overgeneralizing?
  • What are the facts, and what are my interpretations?



Fact versus feeling/thinking

Sometimes you might confuse your thought or feelings with reality. You might assume, “If I feel like a loser, I must be a loser.”  These feelings aren’t based on facts; they are just feelings.

Ask Yourself:

  • Am I confusing my feelings with the facts just because I am feeling this way?
  • Am I thinking this way just because I am feeling bad right now?




When you use labeling you take one characteristic or fault of a person, and apply it to the whole person. Instead of thinking, “He made a mistake,” you might call your co-worker “an idiot.” You are basing your labeling of the person on one individual incident.

Ask Yourself:

  • What are the facts, and what are my interpretations?
  • Just because there is something that I’m not happy with, does that mean that I’m totally no good? ?



Can’t stand “itis”

People can become very intolerant when they have things to do they don’t enjoy. They tell themselves they can’t stand certain things instead of just acknowledging that they don’t enjoy them. As a result, they very quickly become frustrated and angry. We call this can’t stand “itis.”

You need to accept that frustration is a normal part of life and that we can’t always get what we want. Be open to new situations, and you might find that what you thought you couldn’t stand, you enjoy.


The most important step is recognizing these common thinking errors as they are occurring. Once you recognize these thinking errors, you can begin to challenge your way of thinking and correct the patterns. Your end-goal should be to replace negative thoughts with realistic ones. Changing your way of thinking and recognizing your thinking errors won’t happen overnight; it takes time.

Don’t get frustrated, be patient, and you will see changes in your mental state. If you’d like to read more about the topic, check out David Burns’s book, Feeling Good: The New Mood Therapy and download our free Thinking Errors Worksheet

    Our minds are capable of doing so much good but we often allow them to do so much harm – often to ourselves. Attitude is so important in life, and your post shows exactly why.
    It’s an excellent post and great advice from the health care professional. We really need to try to be aware of how we are thinking to avoid some of those seriously damaging issues.

    • Scott DeNicola

      The mind can be tricky at times for sure!

  2. Emily

    I definitely tend to catastrophize! Plus I have anxiety so I get sucked into a hole of worst-case scenarios and nerves. I have to remind myself to take a step back and try to just focus on the present and not an imaginary future.

    • Scott DeNicola

      I have a sheet you can print out to keep handy for reference. It was something given to me by a therapist years ago. It’s quite handy as a reminder. 🙂

  3. Kelly Martin

    I think I’m guilty of most of these thinking errors. It’s easy to get into a spiral of negative thoughts when things aren’t going your way. I’m making a real effort to stop myself when I start thinking negatively and shift my thoughts to something more positive.

    • Scott DeNicola

      I think at some point or another most have been in one of these categories.

  4. Kileen

    This is a great post, I think it’s so important to be aware of our common thinking errors. Comparison is definitely a big one!


  5. LuLu B - Calabrisella Mia

    I used to constantly think of the worst-case scenario which sent me into panic mode and stopped me from pursuing certain things. I have also been guilty of filtering my thoughts – and thankfully I had friends around me that always brought the positive aspects out. I’m starting to do this much more often and it feels like a huge weight has been lifted. I love the ask yourself questions because it’s those simple questions that can completely change your mind about something! The mind is an incredibly powerful thing – and if we train it to think in a more positive way, things really do work out better!

    • Scott DeNicola

      I feel myself slip back at times and I have to quickly correct my thinking.

  6. Lyosha

    I tend to focus on negative sides when thinking of things I need to do or any changes. Following this list must be tough but I need to start improving my thinking as well

    • Scott DeNicola

      Give it a try Lyosha!

  7. Britt K

    I love this and I think it’s so important for people to take ownership of their thoughts and recognize these patterns. I have seen A LOT of people confusing fact/feeling thinking recently, especially with the rise of popularity of social media. People see things online that trigger an emotional response and it isn’t long before many are reacting and lashing out. It’s important to stop, take a step back and reassess the situation before allowing yourself to blindly respond based on your emotions at any given time!

    • Scott DeNicola

      Thanks for the comment Britt! I couldn’t agree more.

  8. Lene Andersen

    Could not love this post more — definitely going to share it with my readers. Great tips, great to just the questions to prompt you to think a bit more deeply about why you feeling what you are. I think they can imply any situation, but anything about people living with chronic illness, it can be so overwhelming that these questions can be an excellent way to start getting a bit of control back, even if it is only emotionally. It could make a huge difference.

    • Scott DeNicola

      Thanks so much Lene! Would love a share.

  9. Thuy

    I can definitely relate to having the “itis”. It ranges anywhere from “I can’t stand” country music to whiners. I need to work on that

  10. Subhashish Roy

    Controlling our mind becomes so difficult at times especially when it’s got to do with some setbacks that we face. That’s when we need to focus on the power of our positive convictions. Seeing the future is a powerful way I believe to set our focus right. Nice read.

    • Scott DeNicola

      Thanks for the comment Subhashish.

  11. Lyanna Soria

    Those are some great tips to keep in mind. I must say, totally relate in the Filtering part since I do that mistake quite often.

  12. Dreams Abroad

    You read my mind when you write your posts. In this day with social media people compare themselves all the time. It hurts them. They thing acting a certain way or having a material object will make them happy to get them somewhere. Really in fact, hard work and dedication will do it. We will all fail trying to get to our goals but I know there are only so many hours in one day, better make the best of them.

  13. Debra Roberts

    This is a fantastic article! I’m currently working on one about self-righteousness–probably a passive-aggressive musing for my mother, but at least I admit it! 🙂 I’m so over society-driven expectations, religious finger-pointing, and one-sided political thinking. This stuff needs to be said and you have said it all very well!

  14. Luna S

    I am guilty of comparing myself to others often which sometimes leads to not completing the task or over thinking. This post was a great read and well written!
