Availability and Confirmation Biases

I remember hearing a story of my colleague who lost a huge amount of money in forex trading. The very next day, I found myself hesitating to open a trade, not because the trade was wrong, but because that story was still stuck in my head. I have also seen people who watched Bitcoin rise from 300,000 pesos to 3 million, and now they expect the same kind of return every time they invest in crypto. That is Availability Bias at work. It is a mental shortcut where we judge situations based on the stories that come to mind most easily, not on logic or solid data. The truth is, our memory does not work like a calculator; it works like a storyteller. And the stories that linger are usually the most recent, emotional, or dramatic, even if they are not the most accurate or useful.

What Is Availability Bias?

Availability bias is a cognitive bias that causes people to overestimate the probability of events that they can easily recall, especially if those events are recent or emotionally charged. Conversely, it also leads people to underestimate the probability of events that are not easily remembered, even if they are statistically more likely. This bias was first described by psychologists Amos Tversky and Daniel Kahneman, who showed that people often make decisions not based on actual statistics or objective reasoning, but on how quickly examples pop into their minds. In other words, what you remember most clearly often feels more real even if it is rare or exceptional.

We all fall into availability bias without even noticing it, and it shows up in many areas of life. After seeing news about a plane crash, some people avoid flying even though it remains much safer than driving. Hearing about a burglary in a nearby neighborhood might push someone to install an expensive security system, even if break-ins are statistically rare. People may also believe shark attacks are more common than they really are, simply because they have watched them in movies or viral clips. In the end, availability bias tricks us into focusing on what feels vivid and memorable rather than what is truly logical or likely.

Availability Bias in Trading and Investing

In trading and investing, availability bias can quietly distort the way we see risk and opportunity. It makes us judge situations based on recent or vivid memories rather than objective data. This often leads to poor risk assessment, emotional decision making, and missed chances in the market.

One way it shows up is when traders overreact to recent news. A market crash caused by a specific crisis can leave many expecting another crash soon, even if conditions have already improved. They hold on to the memory of fear instead of focusing on updated information. Another example is chasing recent winners. When a stock, currency pair, or crypto asset makes a strong rally, traders often jump in late, believing the trend will continue. The fresh memory of gains overshadows the fact that sharp moves are often followed by corrections. Availability bias also appears when traders avoid trades after a loss. A recent loss feels so real that it outweighs the logic of a strong setup, creating hesitation at the wrong time. Finally, traders sometimes overestimate rare events. For example, seeing someone lose heavily in a margin call might create a fear of leverage altogether, even when proper risk management could prevent such outcomes.

I experienced this myself with a gold trade. I once took a loss when gold dropped suddenly and hit my stop loss. The amount was not significant, but the memory of that loss stayed with me. In the following days, every time I spotted a gold setup, I hesitated. My brain kept replaying that moment, whispering, “Remember what happened last time?” Because of that, I skipped a breakout setup that could have easily recovered my loss and given me more profit. Looking back, I realized I was not analyzing gold logically, I was reacting to a memory. That single event had hijacked my judgment and pulled me into availability bias.

The lesson I learned is that our brains hold on to emotional memories more strongly than logical analysis. If we do not train ourselves to separate emotion from market structure, our decisions will always be influenced by what feels most memorable rather than what makes the most sense. Recognizing this bias is the first step to overcoming it and making better trading decisions.

How to Overcome Availability Bias

Availability bias is not a flaw. It is a mental shortcut that developed to help us make quick decisions when faced with uncertainty. Imagine early humans encountering danger. If one of them saw a tiger near the river, they would avoid that river. They avoid the place not because they analyzed statistics of tiger attacks, but because they remembered what happened the last time. In such dangerous situations, a quick memory often outweighed slow and careful analysis. However, in modern finance, this instinct can work against us. Financial markets are complex and driven by data. Reacting emotionally to recent events can often do more harm than good.

We cannot completely eliminate availability bias, but we can learn to manage it. Here are some strategies I use over the years as a futures trader:

First, I use data and not drama. I make my trading and investment decisions based on facts and strategy instead of emotions. I focus on long-term patterns rather than just recent events. Second, I keep a trading journal. I record my trades, my reasons for making them, and the results. When fear or strong memories influence my thinking, I review my journal and ask myself whether my feelings are based on evidence or emotion. Third, I slow down. Bias thrives when decisions are made in a hurry. I give myself time to think before acting. I step back and review my analysis. I ask if I would still make the same decision if I had not just experienced a recent loss or gain. Fourth, I practice statistical thinking. I study probabilities and think in terms of odds instead of stories. For example, just because my last three trades were winners does not guarantee the fourth will be. Each trade stands on its own. Finally, I limit my exposure to noise. Constant news updates and social media can overwhelm my mind with vivid, dramatic stories that trigger availability bias without my awareness. I focus on trusted sources and reduce my intake of emotional content.

Availability bias is one of the most subtle and powerful mental traps in finance. It convinces you that what is vivid or recent is also most likely. It replaces careful analysis with anxiety and turns short-term memories into long-lasting fear or false confidence. But you can learn to recognize this bias. You can train your mind to pause and reflect, choosing reason over reaction. You can make decisions not based on what you remember most clearly, but on what the market data truly shows. The next time you hesitate because of a recent loss or rush to chase a trade after a win, ask yourself: Am I responding to the current reality, or just to a loud memory? Be mindful. Be objective. Because in trading, the most dangerous story is often the one you keep replaying in your mind.

Confirmation Bias: When Your Mind Chooses What It Wants to Believe

I remember a time when I was completely convinced a certain currency pair was about to move in my favor. I spent hours digging into analysis that supported my belief and felt a rush of excitement whenever I found traders on social media sharing the same outlook. Every bullish comment felt like confirmation that I was on the right track. But whenever I came across warnings or bearish reports, I brushed them aside or told myself they were overblown. Looking back, I realize I wasn’t being objective. I was caught in confirmation bias. My mind was only accepting the information that agreed with me while shutting out anything that suggested I could be wrong.

Why Do We Have Confirmation Bias and how to avoid them?

The human brain craves certainty and consistency. Holding conflicting thoughts or admitting we might be wrong feels uncomfortable. So, our minds take shortcuts to protect our existing beliefs and avoid mental discomfort. This bias helps us feel secure, but it can lead us far away from the truth especially when it comes to trading, investing, or any decision involving uncertainty.

When confirmation bias takes over, it distorts how we process information. We begin interpreting facts in a way that supports our preconceptions. This often leads us to ignore warning signs or risks, overestimate the strength of our ideas, and make costly decisions based on incomplete or misleading information. It can also prevent us from learning from mistakes because we refuse to accept them. In the markets, where conditions change constantly and new data emerges every second, holding onto outdated beliefs without question can result in serious losses.

The good news is that with awareness and consistent practice, it is possible to reduce the grip of confirmation bias. One effective approach I do is to actively seek out contradictory evidence. Instead of only focusing on data that supports my belief, I challenge myself to look for opinions and analysis that suggest the opposite. Although uncomfortable at first, this habit helps build a more balanced perspective. Another strategy is I play the role of devil’s advocate with my own ideas. I ask myself, “What if I am wrong? What would have to happen for that to be true?” This mindset forces me to evaluate my assumptions more critically instead of relying on emotion. Over time, this practice reveals patterns of cherry-picking information and helps me train my mind to think more objectively.

Surround yourself with people who are willing to provide honest feedback. Whether it is mentors, peers, or trading communities, outside perspectives can expose blind spots and help you see a bigger picture than you might notice on your own. Above all, it is important to stay humble and open-minded. No trader is right all the time. Markets are unpredictable, and flexibility is one of the greatest assets a trader can have. By embracing uncertainty instead of resisting it, you put yourself in a stronger position to adapt and grow.

Final Thoughts: Choosing Truth Over Comfort

I’ve learned the hard way that confirmation bias is not something you can completely escape. It sneaks in quietly, no matter how much experience you have. There were times I was so focused on being “right” that I ignored the bigger picture, and those moments usually cost me. The real turning point for me was recognizing that my comfort in being reassured was actually blinding me from seeing the truth. Now, whenever I notice myself getting too attached to a trade or an idea, I stop and ask, “Am I really looking at the full story, or just the parts that feel good? If new evidence shows up, am I willing to change my mind?” That simple pause has saved me from repeating painful mistakes.

What I’ve come to realize is that the best traders are not the ones who never mess up. They are the ones who keep questioning themselves, who are willing to learn from reality, and who have the courage to adapt even when it feels uncomfortable. So whenever I catch myself leaning too much toward information that supports what I already believe, I remind myself: the real growth is in facing the truth, not in clinging to comfort.
