Torque Theory: Wired for Growth

Why Authenticity and Positivity Outperform Criticism in the Long Run

There’s a growing movement in science and psychology that explains something many of us in trades and motorsports have long suspected: the mindset you choose directly shapes your outcomes.

We often hear catchphrases like “stay positive” or “be authentic,” but what if there was concrete neuroscience to back it up? According to Emily McDonald, neuroscientist and brain coach behind @mindcraftmethod, there is. And her insights have profound relevance for women navigating traditionally male-dominated industries.

McDonald explains that complaining, judging, or criticising others doesn’t just bring the vibe down—it rewires your brain to do more of the same. Every time you complain, you strengthen the neurological pathway that recognises problems. This is Hebb’s Law in action: *”Neurons that fire together, wire together.”

So if you’re constantly focused on what’s broken, unfair, or frustrating, your brain becomes better at spotting those things—but worse at solving them. It literally weakens your prefrontal cortex, the area responsible for decision-making, focus, and emotional regulation.

It gets worse: negative thinking and chronic stress shrink the very part of your brain that fuels performance. In short? Your ability to lead, respond effectively, or think creatively takes a hit. Meanwhile, your ability to point fingers and spiral into “why me?” grows stronger.

 

But here’s the good news: the opposite is also true.

Emily says that living authentically—showing up as your full, flawed, honest self—activates and strengthens your prefrontal cortex. That means better focus, more motivation, clearer decision-making, and greater resilience. Trying to be who others expect you to be actually triggers the stress response in your brain.

Your body can’t distinguish between performing inauthenticity and being in danger. In both cases, cortisol rises and creativity shuts down. You shift into survival mode. But when you’re unapologetically yourself, you gain energy. Dopamine increases. Self-trust builds. And the compound effect of that state is success.

You don’t become successful by performing the version of you people like best. You become successful by being the version of you that shows up and does the work consistently, authentically, and with purpose.

 

First proposed by psychologist Donald Hebb in 1949, Hebb’s Law says that when two neurons fire at the same time, the connection between them strengthens. Do it enough times, and the brain begins to default to that pathway.

That’s why habits—both good and bad—become so ingrained. That’s why people who think positively tend to see more opportunity. And why those who stay stuck in negativity often feel like the world is out to get them.

But there’s a powerful lesson in this: your brain is plastic. It changes based on what you feed it. That means you can retrain yourself to focus on solutions, gratitude, joy, and growth. It just takes repetition, intention, and awareness.

 

In industries where women often face extra scrutiny, self-doubt, and the pressure to “prove” themselves, this science is a game-changer.

You don’t need to become a robot or silence your emotions. But you do need to be intentional about how you respond to challenges. Do you fall into the spiral of venting and catastrophising? Or do you pause, acknowledge the frustration, then shift into problem-solving mode?

Your mindset can be your most underutilised tool. One that sharpens with every repetition.

 

Your brain doesn’t care about your intentions—only your patterns. That means:

If you practice gratitude, your brain will find more to be grateful for.

If you practice curiosity, your brain will stay open to learning.

If you practice judgment, your brain will find fault faster than it finds solutions.

Your mindset is a muscle. Use it wisely.

 

Authenticity isn’t fluff. It’s a strategic advantage. Being yourself in a world that often pressures you to conform is not only brave—it’s biologically beneficial. It makes you sharper, more motivated, more resilient, and more likely to succeed.

 

The next time you catch yourself spiralling into negativity or trying to meet someone else’s expectation, stop and ask:

What do I need to show up as the best version of me today?

What would happen if I believed in myself as much as I believed in the version others expect?

You don’t get what you want in life. You get what your brain is wired for.

Wire it for joy, for courage, for success. And show up as you.
