The Thinking Traps Keeping You Stuck: Cognitive Distortions, Low Assertiveness & Why It Matters

"You've been so busy managing everyone else's feelings that you've forgotten you're allowed to have your own."

If you've ever left a conversation feeling as though you said the wrong thing, took up too much space, or somehow let someone down, even when you can't quite explain how - this is for you.

What often sits beneath those feelings is a combination of two things that rarely get talked about together: cognitive distortions (unhelpful thinking habits) and low assertiveness. Separately, each one can make life harder. Together, they can quietly dismantle your confidence, your relationships, and your sense of self.

What Are Cognitive Distortions?

Cognitive distortions are habitual patterns of thinking that feel completely true inside your head, but are skewed, exaggerated, or simply inaccurate. They were first identified through Cognitive Behavioural Therapy (CBT) research and are associated with anxiety, depression, low self-esteem, and a range of relationship difficulties.

The tricky thing about cognitive distortions is that they don't feel like distortions, or bad habits. They feel like facts, real, useful thoughts!

That's what makes them so powerful, and so worth understanding.

What Is Low Assertiveness?

Assertiveness is the ability to express your thoughts, feelings, needs and boundaries clearly and respectfully, without aggression, and without collapse.

Low assertiveness doesn't mean you're weak or passive. Often, it means you've learned (usually at a young age) that expressing your needs was unsafe, inconvenient, or likely to lead to rejection or conflict. So you adapted. You became accommodating, self-effacing, agreeable.

The cost? Over time, your own needs become invisible. Even to you!

How They Feed Each Other

Cognitive distortions and low assertiveness don't just coexist, they reinforce each other in a cycle that can be very difficult to break without awareness:

• A distorted thought tells you that speaking up will lead to a problem situation 

• Low assertiveness means you stay silent to prevent that imagined situation 

• The silence "confirms" the distorted belief  - nothing went wrong because you said nothing

• Your confidence in your own voice erodes further

Let's look at five of the most common distortions linked to low assertiveness, and what they actually cost you.

The 5 Key Thinking Distortions Linked to Low Assertiveness

1. Mind Reading - "I already know what they think of me"

Mind reading is the assumption that you know what another person is thinking — usually something negative about you, without any real evidence.

"She went quiet after I spoke. She definitely thinks I'm stupid." "He didn't reply straight away. He must be annoyed with me."

In the context of assertiveness, mind reading becomes a reason not to speak up. If you're convinced someone will react badly, why bother? The result is self-silencing and the relationship never gets the honesty it needs.

The reality: You don't actually know what other people are thinking. You are likely projecting your own fears onto them. Most of the time, people are preoccupied with their own inner world, not scrutinising yours.

2. Catastrophising - "If they disapprove, everything will fall apart"

Catastrophising means taking a possibility, even a small or unlikely one and immediately jumping to the worst-case outcome.

"If I say how I really feel, they'll leave me." "If I get this wrong, my whole career is over." "If I disagree, they'll think I'm difficult and I'll lose the friendship."

For someone with low assertiveness, catastrophising is often what prevents them from ever testing reality. The anticipated outcome is so terrible that avoidance feels like the only rational response.

The reality: The feared outcome is rarely as likely, or as catastrophic as it feels. Assertiveness, practised with care, typically leads to more respect and closer relationships, not the collapse of them.

3. Personalisation - "Their mood is my responsibility"

Personalisation is the habit of taking excessive responsibility for other people's emotional states, moods, and reactions, even when there is no logical connection to you.

"She seems upset. I must have done something wrong." "He's stressed today. I should have been more supportive." "They cancelled plans, they must be pulling away from me."

This distortion is exhausting. It turns every social interaction into a performance review. And it makes assertiveness feel dangerous, because if you're already responsible for everyone's feelings, then saying something they don't like feels catastrophic.

The reality: Other people's emotions are theirs. You can care about someone and still recognise that you are not the cause of, or solution to, all of their feelings.

4. All-or-Nothing Thinking - "I must please everyone, or I've failed"

Also called black-and-white thinking, this distortion leaves no room for nuance. Things are either perfect or terrible, successful or a complete failure, loved or rejected.

"If even one person is disappointed in me, I've let everyone down." "I either handle this perfectly or I've ruined everything." "If I can't meet all of their needs, I'm not good enough."

All-or-nothing thinking makes assertiveness feel binary and terrifying: either you please everyone and succeed, or you express a need and everything unravels. There's no middle ground, because the thinking pattern doesn't allow for one.

The reality: Most of life exists in the grey. Is that uncomfortable for you?

You can disappoint one person and still be a thoughtful, caring, valued individual. You can get something wrong and still be more than enough.

5. Overgeneralisation - "One rejection means everyone will leave"

Overgeneralisation takes a single event (usually a negative one) and treats it as evidence of a universal pattern.

"They criticised me. People always find fault with everything I do." "That relationship ended badly. I'm clearly not capable of maintaining close relationships." "I tried to speak up and it didn't go well. Being assertive never works for me."

This distortion makes recovery from difficult experiences almost impossible. One bad outcome becomes proof that the same outcome will always follow. And so the learned helplessness deepens.

The reality: One data point does not make a pattern. Difficult conversations sometimes go badly. That doesn't mean assertiveness is dangerous, it means communication is complex, and skills develop over time.

The Wider Impact

Left unchallenged, this combination of cognitive distortions with low assertiveness, doesn't stay contained. It spreads.

On Relationships

When you can't express your true feelings, needs or limits, intimacy suffers. Resentment builds quietly. You may attract or remain in relationships that are unbalanced, because those dynamics feel familiar. Over time, people around you may not actually know you, they know the version of you that's trying to keep everything smooth.

On Mental Health

Chronic self-suppression is a significant contributor to anxiety and depression. When your inner experience is consistently overridden by what you think others need, the disconnection can become profound. You may find yourself feeling numb, burnt out, or persistently sad, without quite knowing why.

On Self-Esteem

Self-esteem is built, in part, through the experience of being seen, heard and respected and that includes by yourself. When you habitually dismiss your own thoughts and needs, you send yourself a message: ‘your experience doesn't count’. 

Over time, that message becomes a belief. And beliefs shape everything.

So What Can You Do?

The good news and this is genuinely good news, is that these patterns are learned. Which means they can be unlearned. Not overnight, and not without effort. But they can shift.

A few starting points:

• Notice the thought before you act on it. What are you telling yourself? Is there evidence for it, or is it a familiar story?

• Challenge the catastrophe. Ask: what is the most likely outcome, not the worst possible one?

• Start small with assertiveness. You don't have to overhaul your communication overnight. One honest sentence is a beginning.

• Seek support. Cognitive Behavioural Hypnotherapy, schema therapy, and assertiveness training can all help. Working with a therapist gives you a safe space to practise and unpick these patterns with guidance.

You deserve to take up space. You deserve to have your needs matter. And you deserve relationships with others and with yourself that are built on honesty rather than fear.

That starts with recognising the thinking traps. And then, gently, choosing not to be ruled by them.
