Inside Your Brain: Money, Biases, and Behaviour

Have you ever regretted a purchase, but did it again anyway? Maybe you’ve bought stocks during a market high or overspent during a sale, even though you knew better. You’re not alone. These irrational money behaviours are more common than you’d think.

You might believe your financial decisions are logical. But in reality, your brain is constantly playing tricks on you. The field of behavioural finance reveals how psychology, rather than pure numbers, often drives our money choices.

This post explores the patterns and pitfalls in how we think about money, and how understanding them can improve your product sales, investments, and daily budgeting.

What Is Behavioural Finance?

The study of how psychological influences affect market outcomes and personal financial decisions is Behavioural finance. Unlike traditional finance, which assumes people act logically, behavioural finance says: they don’t.

Behavioural economics combines psychological insights with economic principles. Traditional economics often overlooks how people actually think, choosing instead to simplify decision-making processes to make models simpler.

  • Analysts examine behavioural finance from multiple viewpoints, not just limited to stock market returns.
  • In the stock market, psychological behaviour frequently influences outcomes and returns.
  • The broader aim of behavioural finance classification is to understand why individuals make specific financial decisions and how these choices impact market dynamics.
  • Behavioural finance assumes that investors are not entirely rational or consistently self-disciplined.
  • Instead, individuals display psychological influences alongside relatively normal and moderately self-controlling behaviours.
  • Financial decision-making often depends on both mental and physical health.
  • When an investor’s health improves, their mental clarity typically strengthens, resulting in more rational financial choices.
  • Conversely, a decline in health can lead to poorer judgment and less consistent decision-making across all real-world matters, including financial ones.

Key Concepts in Behavioural Finance Theory:

Bias Description Real-World Impact
Anchoring Bias Relying heavily on the first piece of info E.g., setting product price too high
Loss Aversion Avoiding losses at all costs Holding onto bad investments
Herd Mentality Copying others without their own analysis Buying when everyone is buying
Overconfidence Overestimating own knowledge Excessive risk-taking in stock trading

How to Apply Behavioural Finance in Real Life

A client we once advised—an SME owner in Pune—had invested in a marketing tool that was underperforming. Even after three months of poor ROI, they refused to cancel the subscription. 

Why? 

Because they had already spent ₹20,000 and felt it would be a waste to stop now.

Behavioural finance emerged to explain exactly this: why rational financial models fail when applied to real human behaviour. And it’s helping businesses, from solo entrepreneurs to Fortune 500s, correct those instincts.

Even product sales teams fall prey. When launching a new item, anchoring can cause businesses to price too high based on competitor pricing, rather than actual demand and perception.

Turning Psychology into Profit: A Step-by-Step Guide

In 2025, financial markets experienced a prolonged bear phase that noticeably affected investor confidence and overall market stability. 

This shift raised fresh concerns about speculative behaviour and the spread of misinformation during uncertain times.

So, how do you put these insights into practice? 

Here’s a framework:

  1. Recognise the Bias
  • Keep a decision log. Write down why you’re making a financial choice.
  • Revisit it after a month to spot patterns in logic versus emotion.
  1. Use Framing to Your Advantage
  • Frame product pricing as savings rather than costs.
    E.g., Instead of “₹100 off”, say “Save ₹100 today only”.
  1. Apply Behavioural Nudges in Product Sales
Technique How It Works Application in Sales
Scarcity Highlight limited availability “Only 2 left in stock!”
Social Proof Showcase testimonials, ratings, or usage data “Used by 20,000+ customers”
Defaults Pre-select popular options “Best Seller” tag on recommended plans
  1. Train with Behavioural Finance Knowledge
  • Courses like the ACCA course integrate behavioural modules into financial planning, helping you make informed, emotionally intelligent decisions.

Key Biases and Business Outcomes

Think about your last three money decisions. Did you really compare the alternatives? Or did you follow a gut feeling, a flashy deal, or a friend’s advice?

Understanding behavioural finance doesn’t just help you make smarter investments. It rewires your thinking to approach product sales, budgeting, and even personal goals with more clarity and discipline.

It’s not magic. It’s psychology—with data.

Behavioural Bias Description Business Impact
Loss Aversion Fearing losses more than valuing gains Delayed exits from bad projects
Anchoring Fixating on initial information Inflated product pricing
Herd Behaviour Following the crowd blindly Poor stock timing decisions
Status Quo Bias Sticking to existing choices Low adoption of new tools

What is Behavioral Finance? Exploring the Psychological Factors Influencing Investment Decisions

Behavioral finance is the study of economic affairs and psychology. Behavioral finance shows how an investor makes emotional financial decisions contrary to conventional business decisions. Unlike traditional finance, behavioral finance shows how emotional biases and human feelings are incorporated into decision-making.

An important feature of behavioral finance is the impact of psychological bias on investment decisions. Understanding behavioral finance bias is crucial for implementing business decisions in an organisation. Read on to gain a deeper insight into financial bias.

What is behavioral finance?

Behavioral finance is an amalgamation of psychology and economic matters. It is important to evaluate the impact of emotional bias on financial decision-making. While traditional finance assumes rationality of business decisions, behavioral finance acknowledges the irrationality of decisions based on biases. Primarily, behavioral finance biases revolve around five key concepts:

  • Mental accounting refers to the tendency of individuals to allocate resources for particular purposes.
  • Emotional gap refers to the inclination to make decisions based on strained emotions.
  • Herd behaviour refers to how an individual tends to mimic the financial behaviour of most individuals. Herd behaviour is quite prevalent in the stock market.
  • Self-attribution refers to the inclination of an individual to make decisions with excessive reliance on one’s expertise. The bias of overconfidence lies at the root of self-attributive behavioral finance.
  • Anchoring refers to the association of a spending level with a particular reference.

To understand the concepts of behavioral finance it is recommended to enroll in financial services courses by Imarticus.  

An exploration of the psychological factors that affect business decisions

Cognitive factors have a significant impact on investment outcomes. A few key psychological factors that influence business decisions are described below:

Overconfidence bias

Investors often tend to overestimate their predictive power and knowledge while making business decisions. Overconfidence bias compels investors to execute frequent trades leading to the incurrence of risks. For example, an investor may ignore a market downturn and continue trading despite the risks leading to poor portfolio performance.

Loss aversion

Investors often prefer avoiding losses to attaining equivalent profits. The loss aversion theory suggests that the pain of incurring a loss is more impactful than the pleasure of acquiring gains. For example, an investor may decline to sell a deteriorating stock hoping that the price of the stock may rebound.

Confirmation bias

Investors tend to extract information that confirms the existing beliefs of the investor despite contradictory evidence. Such investors tend to focus on positive news updates about a particular stock while ignoring the associated risks. Ignoring the signs of deteriorating market trends often results in poor investment decisions and losses.

Regret aversion

Regret aversion refers to an irrational fear of making regrettable investment choices leading to avoidance of making decisions. Regret aversion bias goes beyond fiscal loss to emotional discomfort. Investors tend to avoid the sale of collapsing assets fearing that they may regret the business decision. This leads to wasted prospects of portfolio diversification.

Bias of fear and greed

Fear and greed often influence value investing and behavioral finance decision-making in an organisation. Emotional investing causes poor decision-making in stock trading. Fear and greed trigger volatile market trends and stock crashes.

Mental accounting

Mental accounting is a behavioral pattern of treating assets differently based on the source of the assets. Instead of assessing the overall financial state, investors make random business decisions based on the source of the stock. Mental accounting often leads to irrational decision-making in business. For example, an investor tends to be traditionalist about retirement savings while spending money thoughtlessly from a different account.

Recency bias

Recency bias makes an investor prioritise recent market patterns over historical data. Stockholders generally tend to give more importance to short-term market development and make flawed decisions. For example, an investor may chase current market trends and incur losses due to neglect of historical market patterns.

Anchoring bias

Shareholders often feel inclined to rely on a particular piece of market information while ignoring other factors. This piece of market information is considered an anchor. Investors often skip rudimentary market analysis and choose to stick to their anchor bias for making business decisions. For example, a stockholder may hold onto an asset until the asset process reaches a past peak price while simultaneously ignoring current market patterns.

Herd bias

Herd bias is one of the most prominent biases that investors harbour. Shareholders tend to imitate the behaviour of a larger group of investors while neglecting appropriate analysis of the market. Herd behaviour creates a bandwagon effect in which stockholders tend to follow generic trading patterns instead of conducting independent evaluations. Such a bias often results in market crashes and asset bubble formation. For example, purchasing a booming asset without assessing the company incurs huge losses when the asset bubble bursts.

Availability bias

Availability bias refers to a behavioral tendency to give undue importance to news and personal experiences. Such a bias can compel investors to waste profitable opportunities depending on what is readily available in their minds. Such investors tend to invest in assets based on success stories while neglecting an evaluation of the assets.

Conclusion

Psychological factors like herd mentality, overconfidence, and emotional biases have a great impact on business decisions. Behavioral finance recognises the infusion of emotions and business decisions. Awareness of psychological influences helps in avoiding investment errors and making rational decisions.

Budding investors may consider enrolling in the Advanced Management Programme in Financial Services and Capital Markets at Imarticus to understand behavioral finance.
