Your Brain is a Liar: Why Most "Realistic" Thinking is Actually Self-Sabotage

Here's something that'll ruffle feathers at your next networking event: positive thinking isn't some new-age nonsense, and "realistic" thinking is often just pessimism wearing a business suit. After two decades consulting with everyone from mining executives in Perth to tech startups in Melbourne, I've watched brilliant professionals torpedo their own careers with what they proudly call "being realistic."

The human brain, magnificent as it is, evolved to keep us alive in a world where saber-toothed tigers were genuine concerns. It wasn't designed for quarterly reports, performance reviews, or LinkedIn updates. Yet here we are, using Stone Age wiring to navigate 21st-century challenges.

The Catastrophising Epidemic

Let me paint you a picture. Sarah, a project manager I worked with in Brisbane, received feedback that her presentation "could use more data visualisation." Her brain immediately translated this into: "I'm terrible at presentations, my boss thinks I'm incompetent, I'll never get promoted, and I should probably start looking for another job."

Sound familiar?

This is catastrophising—taking a minor setback and mentally fast-forwarding to complete disaster. It's like stubbing your toe and immediately planning your funeral. We've all been there, but some of us have set up permanent residence in Worst-Case-Scenario-ville.

Research shows that 78% of business professionals engage in catastrophic thinking at least weekly. That's not my statistic—that's from people who actually count these things properly, unlike the rest of us who just wing it with "most people" or "everyone knows."

The kicker? Sarah's boss had intended the feedback as a minor suggestion to enhance an otherwise solid presentation. But Sarah's brain had already written her career obituary.

Mindreading: The Business World's Favourite Delusion

Another classic distortion is mindreading—assuming you know what others are thinking. I've lost count of the number of times I've heard: "He didn't respond to my email immediately, so he must hate my proposal" or "She looked annoyed in the meeting, clearly she thinks I'm useless."

Here's the thing: we're terrible at reading minds. Absolutely shocking at it. That person who looked "annoyed" might have been concentrating, hungry, or dealing with their teenager's latest drama. But our brains love a good story, especially if it casts us as the victim.

I learned this lesson the hard way back in 2008 (yes, during the GFC—lovely timing). I was convinced a major client was about to drop us because their usually chatty CEO had become monosyllabic in meetings. Turns out, his father had been diagnosed with dementia. My "expert reading" of his behaviour was completely wrong.

The truth is, most people are too busy worrying about their own problems to spend much time judging yours.

All-or-Nothing: The Perfectionist's Poison

Then there's black-and-white thinking, the perfectionist's drug of choice. Everything is either brilliant or terrible, success or failure, with no middle ground. I see this constantly in high-achievers who can't celebrate a 95% success rate because they're obsessing over the 5% that went wrong.

Take Marcus, a financial advisor who landed 8 out of 10 prospects in a month. Instead of celebrating an 80% conversion rate (which is phenomenal), he spent weekends agonising over the two that got away. "I'm obviously losing my touch," he declared dramatically.

This is like a cricket team complaining about losing one match in a winning season. Ridiculous when you put it like that, isn't it?

For those looking to develop better leadership skills for supervisors, recognising these thinking patterns in yourself and your team is crucial. You can't lead others effectively when your own mental software is running on faulty code.

The Filtering Function From Hell

Our brains come equipped with a sophisticated filtering system that would make a coffee machine jealous. Unfortunately, it often filters out the good and amplifies the bad. You receive ten pieces of feedback—nine positive, one constructive—and guess which one keeps you awake at 2 AM?

This mental filter is why performance reviews feel like root canal procedures for so many people. The brain discounts praise as "just being nice" but treats criticism as gospel truth. It's like having a personal critic who never takes a day off.

I remember one workshop I ran for a construction company (great bunch, terrible coffee). The foreman mentioned how his team would remember every complaint from clients but forget dozens of compliments. "It's like we're programmed to focus on what's broken," he said. Spot on, mate.

Fighting Back Against Your Brain's Bad Habits

Now, before you think I'm suggesting we all skip around singing kumbaya, let me be clear: the goal isn't toxic positivity. It's balanced thinking. Realistic optimism, if you will.

Here's what actually works:

The Evidence Test: When your brain serves up a particularly dramatic interpretation, ask for evidence. "My boss thinks I'm incompetent" needs to be backed up with actual data, not just your overactive imagination.

The Friend Test: What would you tell a mate in the same situation? We're often much kinder and more rational when advising others than ourselves.

The 10-10-10 Rule: Will this matter in 10 minutes, 10 months, or 10 years? Most of our daily dramas fail this test spectacularly.

Those interested in exploring more about employee supervision will find these cognitive tools invaluable when managing teams. After all, if you can't manage your own thinking, how can you effectively guide others?

Sometimes I catch myself slipping back into old patterns. Just last month, I assumed a client's delayed payment meant they were unhappy with our work. Reality? Their accounts person was on annual leave. My brain had created an entire narrative around late payments, difficult conversations, and potential contract cancellations. All nonsense.

The Comparison Trap

Let's talk about something we all do but pretend we don't: comparing ourselves to others. Social media has turned this into an Olympic sport, but it existed long before LinkedIn made everyone's career highlights visible 24/7.

"Everyone else seems to have it figured out" is perhaps the most common distortion I encounter in coaching sessions. Trust me, nobody has it figured out. We're all just making educated guesses and hoping for the best.

The person you're comparing yourself to might be projecting confidence while secretly googling "how to quit job without looking like a failure" at 3 AM. You're comparing your behind-the-scenes reality to everyone else's highlight reel.

When Your Inner Critic Goes Rogue

Your internal monologue probably wouldn't be tolerated if it came from another person. "You're terrible at this," "Everyone can see you don't belong here," "You're going to mess this up"—imagine if a colleague spoke to you this way. You'd report them to HR faster than you could say "workplace harassment."

Yet we allow our own minds to bully us relentlessly.

The solution isn't to argue with these thoughts (that's like wrestling with a pig—you'll both get dirty, and the pig enjoys it). Instead, acknowledge them and move on. "Thanks, brain, for that unhelpful opinion. Now, what's the next action I need to take?"

The ROI of Better Thinking

Here's where the business case gets interesting. Poor thinking patterns don't just affect mood—they impact performance, decision-making, and leadership effectiveness. A study of 500 Australian managers found that those who learned to recognise and challenge cognitive distortions saw a 23% improvement in team engagement scores within six months.

Companies like Telstra and Woolworths have started incorporating cognitive awareness training into their leadership development programs. Not because they've gone soft, but because clear thinking drives better results.

There's also growing recognition that supporting employee well-being through better mental frameworks reduces sick leave, improves retention, and boosts productivity. It's not charity—it's smart business.

The Reality Check

Look, I'm not suggesting we all become relentlessly positive robots. Healthy scepticism and critical thinking are valuable business skills. The problem comes when critical thinking becomes automatic negative thinking.

Sometimes things genuinely are going wrong. Sometimes feedback is harsh because performance is poor. Sometimes that colleague really doesn't like you (though probably not for the reasons you think).

The difference between helpful and harmful thinking is asking: "Is this thought accurate, and is it helping me move forward?" If the answer to either question is no, it's time to challenge it.

Breaking the Pattern

Change starts with awareness. For the next week, try catching yourself in the act of distorted thinking. Don't judge it or try to fix it immediately—just notice it. You might be surprised how often your brain serves up these unhelpful interpretations.

When you catch a distortion, try reframing: instead of "I always mess up presentations," try "I need to practice more before my next presentation." Same information, completely different energy.

Remember, your brain isn't your enemy—it's just a well-meaning but overprotective friend who needs better training. After 20 years in business, I can tell you that the most successful people aren't those who never have negative thoughts; they're the ones who don't let those thoughts drive the bus.
