Moving from Information to Decision-making 

Financial literacy has been positioned as the cornerstone of financial wellbeing for some time now. Schools, Governments, financial institutions and charities invest heavily in programmes designed to improve understanding of financial concepts such as spending, budgeting, saving and investing. The underlying assumption here being that once knowledge obtained and understood, better financial decision-making will follow. 

However, evidence suggests that the relationship is not so simple. 

While financial education often improves knowledge, the effect on behaviour is typically smaller and inconsistent. Ultimately, people may learn about interest rates, but still struggle to act on their knowledge when faced with real-world decisions. This gap between understanding and action has led researchers and policymakers to turn to behavioural science as a complementary lens for improvement of financial literacy outcomes.

What is Behavioural Science?
Behavioural science refers to an interdisciplinary field  that draws primarily on psychology and economics to understand how people make decisions in real-world contexts. Contrary to traditional economics, that assumes that individuals are fully rational and always act in their own best interest, behavioural science recognises that decisions are influenced by a multitude of factors which include:
– Cognitive biases (systematic patterns of thinking)

– Emotional Responses 

– Social influences 

– Time pressure and stress 

– The way choices are presented

These factors often strongly shape behaviour, more so than knowledge alone. 

Exploring how to shift financial behaviours through the lens of behavioural science allows for contextualisation of knowledge – for example, present bias explains why individuals have a tendency to prioritise immediate gratification over long-term benefits. Even those who are knowledgeable and understand the importance of saving may choose short-term spending rewards because of the immediacy of it all. Similarly, behavioural science explains that choice overload, when too many options are presented, can lead individuals to make suboptimal or delayed decisions.

These behavioural patterns help to illustrate why financial knowledge does not always translate to improved financial behaviour. 

Limits of Traditional Financial Literacy Approaches 

Traditionally, financial literacy programmes often emphasise delivery of information: workshops, informational campaigns, curricula and guidance materials. While these interventions are valuable, they frequently assume that once someone understands financial concepts, they will automatically apply them. 

Meta-analyses suggest that financial education has modest effects on behaviour – especially when interventions do not take behavioural factors into account. Fernandes, Lynch and Netemeyer (2014) found that financial education explained ~0.1% of variance in financial behaviour, suggesting that others factors play a significant role. There has not been much change in over a decade, where more recent studies echo that emphasis on behavioural interventions can enhance effectiveness of financial education once integrated into programme design (Kaiser & Menkhoff, 2020).

Though it is important to note, these findings do not negate the importance of financial education – they only highlight that financial knowledge alone is insufficient for achieving long-term behavioural change and improving financial outcomes.

How behavioural science strengthens financial literacy 

To simplify this, we will think of the five domains within behavioural science that, once integrated and taken into consideration, would positively affect learning outcomes in financial literacy interventions. These are as follows:
1. Simplification: reducing complexity of financial information and choices can improve decision-making. Simplified disclosures, clear language and structure options reduce cognitive overload and foster effective engagement. 

2. Defaults: Setting beneficial default options (e.g. auto-enrollment for savings account) leverages inertia – the tendency to stick with pre-selected choices. Research shows that defaults can increase participation significantly in savings programmes. 

3. Timing: Delivery financial information the moment it is needed – rather than in advance – increases relevance and uptake. This is often referred to as “just-in-time” financial education. 

4. Framing: the way information is presented influences interpretation – for example, framing savings as “securing your future” instead of “sacrifice” can affect motivation.

5. Social Norms: Highlighting what peers are doing can keep individuals encouraged and foster positive behaviour. Individuals are more likely to adopt behaviours they perceive as socially endorsed. 

The Organisation for Economic Co-operation and Development (OECD) highlighted the importance of these approaches and noted that behaviour insights can improve financial education initiatives via alignment with real-world contexts and decision-making processes (OECD, 2018).

Financial Decisions Happen in Context 

A key contribution of behavioural science is the recognition that financial decisions occur within environments – not in isolation. These environments include:

– product design 

– policy structures 

– digital infrastructures 

– communication styles 

– emotional and social contexts 

When these environments are poorly designed or complex, even those that are financially literate may struggle to make optimal choices. This perspective reframes financial literacy from being solely an individual responsibility to being a shared responsibility between individuals and systems. 

Towards Behaviourally Informed Financial Literacy 

Integrating behavioural science into fiancial literacy oes not mean abandoning education, instead it involves:
– designing programnes that anticipate biases 

– embedding behavioural supports into financial products 

– delivering information at decision points 

 – testing interventions through pilots 

– evaluating behavioural outcomes, not just knowledge gains 

This approach recognises that financial capability develops through practice, reinforcement and supportive environments, rather than knowledge alone. 

Conclusion
Finaicnal literacy remains essential for improving financial wellbeing. However, knowledge alone cannot guarantee better decisions. Behavioural science prvoides a complementary lens that helps explain why individuals sometimes struggle to act on what they know – and how systems can be designed to support better outcomes.

By combining financial education with behavioural insight, institutions can move beyond awareness and toward sustained and meaningful behaviour change. This shift offers a more realistic and effective path to improving financial capability in complex financial environments.
