How the Psychology Behind Our Decisions Really Works

Did you know your brain makes decisions up to 10 seconds before you’re consciously aware of them? It’s as if your brain already did the job while you’re still sitting there believing you’re in control!

The Power of the Unconscious

Decision-making is a complex process influenced by a wide range of psychological factors. Whether we’re facing everyday choices or life-changing decisions, it helps to understand how psychology shapes the way we choose. Let’s explore the key factors that influence how we make decisions.

Unconscious Decisions

A significant part of our decision-making happens at a subconscious level. Ever come home from the store with a new product, only to realize you recently saw it in an ad? You might have been exposed to the commercial without even noticing it. This is called priming – when prior exposure to information influences our choices without us realizing it. Research shows that our brain stores information that can later affect our decisions, even if we don’t consciously remember it.

Words and images can influence decisions without our awareness – like how a rabbit’s ears can suddenly become a duck’s beak, once someone tells you it is.

Cognitive Bias

Cognitive biases are systematic errors in our thinking that lead to less-than-optimal decisions. One of the most common is confirmation bias – where we actively seek out information that confirms what we already believe. For example, someone who’s skeptical of vaccines may avoid reading studies that show their benefits.

Another is the availability heuristic, where we judge the likelihood of events based on how easily we can recall examples. After hearing news about a plane crash, people often overestimate the risk of flying, even though air travel is much safer than driving.

Fun Fact:
Studies show that around 90% of our decisions are driven by emotions rather than logic. That’s why emotional ads can trigger impulsive purchases we might not have planned.

Emotional Influence

Emotions play a huge role in how we decide. Positive emotions can make us more optimistic and impulsive, while negative ones make us cautious. For example, someone in a good mood might be more open to risky investments, while someone feeling sad or anxious might avoid opportunities out of fear.

Fun Fact:
We’re more likely to buy products that make us feel happy. That’s why so many ads use joy, nostalgia, or warmth to create emotional connection.

Social Influence

As social beings, we’re heavily influenced by those around us. Groupthink can cause teams to suppress dissent in order to preserve harmony – often leading to poor decisions. Peer pressure also plays a role, especially for teenagers who might engage in risky behavior just to fit in.

Fun Fact:
In the famous Asch experiment, 75% of participants changed their answers to fit the group’s opinion, even when they knew it was wrong.

Risk and Uncertainty

We typically prefer security over risk – even when the potential reward is greater. Interestingly, when people feel a loss of control, they often become more willing to take risks, like gamblers betting more after a loss.

Fun Fact:
According to prospect theory, losses hurt more than gains feel good. It takes more than a win to emotionally cancel out a loss.

Decision-Making Models

Several models help explain how we make choices. Rational choice theory suggests we make decisions based on logic and data, aiming to maximize benefit. But real life is rarely that rational – emotions and biases often take over.

Prospect theory shows that we value gains and losses differently, which explains why people hold on to losing stocks to avoid realizing a loss – the emotional pain of “losing” is too great.

Short-Term vs. Long-Term Thinking

We often favor instant rewards over long-term benefits – a concept known as temporal discounting. It’s why someone might choose junk food now, even if it hurts their health later.

Fun Fact:
Studies show people frequently choose smaller rewards now over larger ones later – even when the future amount is significantly higher.

Decision-Making Traps

There are many common pitfalls in decision-making. Overconfidence can lead us to take unnecessary risks because we believe too much in our own judgment. Loss aversion can make us avoid risks entirely, based on past failures.

We also tend to underestimate how much information we need to make good choices, which can lead to decision paralysis – putting things off or avoiding decisions altogether.

Fun Facts About Decision-Making

  • Brainwash effect:
    Research shows our brain makes decisions before we consciously do – up to 10 seconds ahead.
  • Priming:
    Simple words or images can guide our decisions. Seeing photos of successful people can increase optimism.
  • Too many options:
    Having too many choices can cause paralysis. Known as the paradox of choice, more options can actually reduce satisfaction.
  • Circadian rhythm:
    The time of day affects our decision-making. We’re more likely to take risks in the evening.
  • Emotional decisions:
    About 90% of our decisions are emotion-based – which is why we sometimes regret choices when we reflect later with a logical mindset.
  • Social risk:
    People take more risks in groups than alone – a phenomenon known as social influence.

In Conclusion

Understanding the unconscious decisions we make – and how marketing plays into them – is crucial to becoming more aware of our choices. In business, it’s not about what you believe in, but why someone else would want to buy into it. That’s why an interest in psychology is a major advantage in sales.

By grasping how decision-making psychology works – including how priming, emotions, and bias guide us – we become better sellers, designers, marketers, developers, or professionals in any field.

I discovered Kolenda over a decade ago and have followed him ever since. He’s brilliant at breaking down academic studies into practical advice rooted in how our brain actually works. His books, talks, and online resources help businesses understand consumer behavior and improve their strategies.

Kolenda’s work covers topics like persuasion, pricing, and how to apply psychological techniques to boost conversions and engagement. He regularly shares his insights through social media, courses, and his website.
