What Is Cognitive Dissonance?
Have you ever found yourself in a situation where you believe one thing, but your actions or other beliefs contradict it? Maybe you’ve experienced the internal tug-of-war between wanting to eat that delicious slice of cake and knowing you should stick to your diet. Or perhaps you’ve witnessed people fervently defending their beliefs despite overwhelming evidence to the contrary. Welcome to the intriguing world of cognitive dissonance and confirmation bias.
A Classic Psychological Conflict
Cognitive dissonance comes from classic psychology. Leon Festinger first explained it in his 1957 book. He described it as the mental discomfort that happens when we hold two opposing ideas at once. It’s like your brain saying, “Wait a minute—this doesn’t add up!” Just like hunger or thirst, this discomfort pushes us to resolve the conflict. We want to reduce the tension and restore mental balance.
Why Do We Feel This Way?
But why does this discomfort arise in the first place? When information clashes with our self-concept, it’s like a direct hit to our core beliefs and values. It challenges the very essence of who we think we are. Imagine making a mistake in something you’re usually good at. You’re faced with a choice: admit the mistake and risk shattering your self-image, or deny the evidence altogether.
Denial Beats Discomfort
Here’s where cognitive dissonance kicks in. Instead of facing the uncomfortable truth, we often ignore or overlook evidence that contradicts our beliefs. It’s like trying to fit a square peg into a round hole—sometimes, it just doesn’t work.
Instead of facing reality, we often rationalise or ignore evidence. It’s like forcing a square peg into a round hole. Take smoking, for instance. Smokers know the health risks, but many still light up. Why? Because facing the truth means accepting the need for change. So instead, they might say things like, “I don’t smoke that much,” or “I’ll quit soon.” These justifications reduce the mental strain.
Confirmation Bias: A Filter for Beliefs
But cognitive dissonance doesn’t stop there. Confirmation bias often joins the party. This is our tendency to search for information that supports what we already believe. At the same time, we avoid or dismiss anything that challenges us.
Think of it as a mental filter. We cherry-pick facts that align with our views and ignore those that don’t. A powerful example of this comes from the 1950s. A cult believed the world would end on a specific date. When it didn’t happen, they didn’t admit they were wrong. Instead, they doubled down, finding new reasons to explain the failed prophecy.
Why Awareness Matters
So, what can we take from this? First, awareness is key. Recognising when cognitive dissonance and confirmation bias are at play can help us approach situations more openly. It’s okay to admit when we’re wrong or when our beliefs are being challenged – it’s a sign of growth.
Second, we need cognitive flexibility. When we allow ourselves to evolve with new evidence, we grow wiser. Being able to hold two ideas in our mind without breaking down is a mark of maturity.
Changing the Way We Think
Yes, cognitive dissonance and confirmation bias are hardwired. But they don’t have to control us. By noticing them and questioning our thinking, we can stay open-minded and grounded. Life is messy, full of contradictions—and that’s okay. Growth comes when we lean into that mess with curiosity. So, the next time you find yourself grappling with conflicting beliefs, remember: it’s all part of the wonderfully messy journey called Life.
Real-World Example: Brexit
Let’s look at a clear case of cognitive dissonance and confirmation bias—Brexit.
During the referendum, emotions ran high. Many believed leaving the EU would bring freedom, control over borders, and new trade deals. These beliefs tied deeply to national pride and identity.
But as reality unfolded, cracks began to show. Economic warnings became real: job losses, supply chain issues, and falling investment. The vision of a bright, post-Brexit future grew dim. Here came the dissonance—beliefs clashed with facts.
Digging in, Not Backing Down
Enter confirmation bias. Despite mounting evidence that Brexit was causing more harm than good, many staunch Brexit supporters doubled down on their beliefs. They sought information that painted a rosier picture, dismissing dissenting voices as “project fear” mongers or unpatriotic naysayers. It was easier to bury their heads in the sand than to confront the uncomfortable truth.
Another Example: Liz Truss
However, cognitive dissonance and confirmation bias aren’t limited to grand political movements. They can manifest on a personal level, too. Take, for example, the case of Liz Truss, the former Prime Minister who championed Brexit and promised a bright future for the UK. In the wake of her tenure, marked by economic turmoil and political upheaval, Truss faces a dilemma.
Instead of acknowledging the failures of her leadership and the damage wrought by her policies, Truss chooses to see only the positives. She promotes her new book, touting her accomplishments and painting a rosy picture of her time in office. It’s a classic case of cognitive dissonance at play – faced with conflicting evidence; Truss opts to cherry-pick the facts that support her narrative while ignoring the rest.
Final Thoughts: Spot the Bias, Choose Growth
So, what can we learn from the Brexit saga and the case of Liz Truss? It’s a sobering reminder of the power of cognitive dissonance and confirmation bias in shaping our beliefs and behaviours. It’s easy to get swept up in the enthusiasm of ideology, to cling stubbornly to our convictions even in the face of overwhelming evidence.
But true wisdom lies in the ability to acknowledge our cognitive blind spots, embrace nuance and complexity, and approach life with humility and curiosity. As the UK navigates the choppy waters of post-Brexit reality, and as individuals like Liz Truss grapple with the consequences of their actions, let’s remember that growth and progress come from facing uncomfortable truths head-on, not from burying our heads in the sand.
