There are things we know, and then there are things we know but cannot yet bear to know. Somewhere between the two lies a vast, quiet machinery of the mind — one that works around the clock, mostly without our permission, to keep certain truths at a manageable distance. We call these defence mechanisms.
It’s easy to hear that phrase and think of defensiveness in the everyday sense — someone getting prickly when criticised. But what we’re describing here is something both more ordinary and more remarkable. These are not signs of weakness or dishonesty. They are the mind doing what minds have always done: protecting us from more reality than we can absorb at once. A certain amount of self-deception, it turns out, may be the price of staying functional. The trouble starts not when we use these strategies — we all do, constantly — but when we get so attached to one that it starts running our lives instead of helping us survive a difficult moment.
Below are ten of the more common ways we do this. None of them are pathological in themselves. Most of them, we’ll recognize from our own lives — often with a wince.
One: Denial
Pretending it isn’t true
The immediate defensive maneuver – the primitive instinct to feel right about oneself – is to pretend that there is no problem. We think things like we don’t have a drinking problem, or that we couldn’t have helped things going wrong even when we could have.
We do this because admitting to the problem would mean that we’re going to have to do all sorts of difficult and awkward things to change it. Things that we aren’t prepared to do, at least in the short term.
Two: Projection
Seeing our own feelings in someone else
We recognize a negative feeling, but instead of owning it or seeing it as one of our own dark emotions, we attribute it to or ‘project’ it onto someone else. This can sound very complicated but it happens a lot.
We’re certain that a certain colleague resents us or we feel that our partner would be disapproving of us if we don’t make enough money while in truth, the colleague doesn’t resent us at all and the partner is very sympathetic towards our failings.
There’s a particular relief in believing that the anger, the desire, or the contempt belongs in the other person and not in us. It’s a strange kind of trade: we locate an uncomfortable feeling in someone else and receive, in exchange, the comforting sense that at least it isn’t ours.
Three: Rationalization
Explaining it away
We are remarkably talented at making reasonable-sounding excuses to explain what we do (or what others do to us), and it’s carefully tailored to make ourselves believe that we’re innocent, nice and worthy.
If we get rejected for a job or a promotion, we tell ourselves that we didn’t want it anyway because the company wasn’t that good, now that we think of it again. We ended the relationship because they “were emotionally unavailable” — not because closeness itself frightened us. The explanations aren’t entirely false, exactly. They’re just not first in line.
Four: Reaction formation
Acting the opposite of how we feel
This involves doing the opposite of our unacceptable feelings. A child might be being mean to their classmate because they’re embarrassed about their attraction towards the classmate instead of admitting it to themselves. The person consumed by envy becomes their rival’s loudest cheerleader.
We can see this as a kind of over-compensating behavior; there’s often something faintly excessive about these reversals — a warmth that’s a little too bright, a meanness little too pointed and a generosity that seems to cost the giver more than it should.
Five: Displacement
Taking it out on someone safer
The boss who humiliated us gets a polite nod on the way out the door; the family gets the fallout that evening. This is one of the mind’s oldest maneuvers — redirecting a feeling toward a target where it’s less dangerous to express. It explains a great deal about why the people we love most sometimes bear the brunt of what strangers provoke in us.
Six: Turning Against the Self
Directing the blow at ourselves instead
If we become defensive to protect ourselves from psychological suffering, it could sound paradoxical to think that hurting, being angry on or loathing oneself could be a defence. However, it’s a matter of what we find more frightening; there can be things that can appear more frightening than disliking ourselves.
When a child, for example, is abandoned or hurt by a parent, they might think that they are bad and worthless. So the conclusion goes — I still have a good parent. It’s painful but less painful than the truth: that one is actually at the mercy of someone who doesn’t care enough.
It can look like humility, even virtue — we seem hardest on the person who “deserves” it most. But underneath, it’s often the only place the feeling could go without costing us the relationship we couldn’t afford to lose.
Seven: Fantasy
Dissociating from the reality by daydreaming
Fantasy avoids problems by imagining them away. We manifest a range of different scenarios in our head: the person feeling ignored might imagine being famous and adored by others or the poor may imagine enjoying the material comforts they cannot afford. The mind generates a hallucination of its solution.
Eight: Splitting
Thinking of people as all-good or all-bad
This defence is often seen at work in romantic relationships: at the beginning of a romantic relationship we tend to think of our partner as perfect or flawless. But soon enough as their flawed, human side becomes all too apparent we turn our perception of them on its head: we go from idealising them to demonising them.
This has little to do with their inconsistency and more to do with our inability to tolerate their complexity. Nuance is not our strongest point or natural resting place: It is a temptation of the human mind to declare things to be either all-good or all-bad.
Nine: Regression
Going back to what once felt safe
Under enough pressure, we sometimes retreat to older, more childlike ways of coping — sulking, needing constant reassurance, losing the capacity we normally have to tolerate frustration. It’s not really about age. It’s the mind reaching for whatever strategy once kept us safe, even if we’ve long since outgrown it.
A tantrum is a common regressive defence mechanism. Rather than look for a solution to a problem, one tries to solve it by getting upset.
Ten: Sublimation
Turning frustration into something constructive and worthwhile
Not every redirection is destructive. Sometimes grief becomes a work of art, restlessness becomes a business, rage becomes activism. This is one of the few defenses that tends to leave something behind worth having — art, achievement, purpose — even though what’s driving it underneath may be pain we haven’t looked at directly.
Sublimation involves redirecting unacceptable thoughts or emotions into ‘higher’ and ideally more constructive channels.
A Note on How We Outgrow These Defences
Because these defenses exist to protect us, they don’t respond well to pressure. We don’t argue our way out of them, and we certainly don’t scare ourselves out of them. We put our guard down for the same reason we put it up: safety.
It’s only when we feel steady enough that we can afford to be more honest — about what we’ve done, what we’re avoiding, and where we fall short. This is really what good therapy offers: not a confrontation, but enough safety that we no longer need the old defenses quite so badly, and can risk learning something truer instead.
